Independent Consulting Case: How I Shaped European Market Expansion for a German eCommerce Client

A German eCommerce Business Ready for Its Next Stage of European Growth

During the COVID period, while living in Munich and working independently as a digital marketing consultant, I worked with a growing German eCommerce client that had built a strong position in its home market.

Germany was the core business. Paid media was performing well, customer acquisition was established, and we had enough history to understand how customers responded across channels, products, web and app.

The business wasn't starting from zero elsewhere in Europe either.

There were already customers, traffic, transactions and early demand signals coming from markets including the Netherlands, France and Austria.

But there was an important difference.

These markets had presence, not scale.

They weren't yet meaningful growth markets for the business, and media investment outside Germany had not reached the level or maturity of the home market.

That created a much more interesting expansion question:

Which of these existing European markets had enough potential to justify serious investment and become the client's next meaningful growth market?

This wasn't a multinational with unlimited budgets, local teams in every country and the ability to invest aggressively everywhere until something worked.

It was a growing eCommerce business.

Expansion therefore had to be commercially disciplined.

My role as an independent consultant was to work out where the opportunity existed, how paid media could validate it, how much investment each market could absorb and how we could progressively turn early demand into sustainable growth.

What started as a market-expansion question developed into a six-month engagement covering the complete journey from analysis to execution and scale.

The Engagement at a Glance

→ Client: Growing German eCommerce business

→ Engagement: Independent digital marketing consulting

→ Core market: Germany

→ Expansion markets: Netherlands, France, Austria and other European opportunities

→ Starting position: Existing customers and demand outside Germany, but limited market penetration and relatively small commercial contribution

→ Objective: Turn selected European markets into meaningful growth contributors

→ Duration: Approximately 6 months

→ Media investment: Multi-million-euro paid-media scale across the business and expansion activity

→ Scope: Market assessment, media strategy, media planning, media buying, tracking, attribution, measurement, optimization and scaling

→ Customer ecosystem: Web + App

The objective wasn't simply to increase international campaign spend.

It was to determine which existing European opportunities could support meaningful scale and then build the media approach required to get them there.

I Used Germany as the Benchmark, Not the Blueprint

Germany gave me something extremely valuable before I started increasing investment elsewhere:

a mature reference point.

I already had visibility into how the business behaved when paid media operated at meaningful scale.

I could understand:

→ Customer acquisition patterns
→ Search and Shopping behaviour
→ Paid Social response
→ Product and category demand
→ Audience performance
→ Creative response
→ Conversion behaviour
→ Web and app journeys
→ Revenue generation
→ How acquisition economics changed as investment increased

Germany therefore gave me a benchmark for what an established market looked like for this particular business.

But I deliberately didn't treat it as the European expansion template.

Austria might share a language with Germany, but it had a different market size and growth ceiling.

The Netherlands had different customer behaviour, competition and media economics.

France represented a considerably larger potential opportunity, but required deeper localization and a different approach to building demand.

Germany showed me what success could look like. It didn't tell me how to create it everywhere else.

I Started With the Demand That Already Existed

Because the client already had some activity outside Germany, I didn't have to make the expansion decision entirely from market reports or forecasts.

I had something much more useful:

actual customer behaviour.

I started looking at what the existing data was already telling me market by market.

That included:

→ Existing orders and revenue
→ Website traffic
→ App activity where relevant
→ Conversion behaviour
→ Search and category demand
→ Product-level interest
→ Existing paid-media performance
→ Customer acquisition patterns
→ Geographic demand
→ Organic and direct demand
→ Existing customer behaviour

Then I combined those signals with the wider market picture:

→ Addressable audience
→ Competitive intensity
→ Media costs
→ Market maturity
→ Localization requirements
→ Potential commercial scale
→ Remaining growth headroom

This immediately made the decision more nuanced than:

“Which country currently has the highest ROAS?”

A smaller market could look extremely efficient while having a relatively limited ceiling.

A larger market could initially be more expensive but offer substantially more room to grow.

And an existing trickle of customers from a market could be particularly interesting if the business was generating that demand without yet putting serious media investment behind it.

Before I Compared Performance, I Made Sure I Could Trust the Measurement

If I was going to use paid-media and customer data to influence where a multi-million-euro media budget should move next, I needed confidence in what the numbers represented.

So I reviewed the measurement foundation.

Tracking

I looked at whether customer actions and commercial outcomes were being captured consistently across markets.

→ Conversion tracking
→ Revenue tracking
→ Web measurement
→ App measurement
→ Conversion definitions
→ Market-level reporting consistency

Attribution

Then I looked at how different channels were receiving credit.

→ Platform-reported conversions
→ Analytics reporting
→ Cross-channel journeys
→ Cross-device behaviour
→ Web-to-app journeys
→ Attribution windows
→ Potential channel overlap

Measurement

Finally, I focused on the question that mattered commercially:

Was additional media investment actually producing additional business growth?

I didn't need attribution to become theoretically perfect.

I needed enough measurement confidence to avoid mistaking a reporting difference for a market opportunity.

I Built a Market-by-Market Opportunity View

Once the measurement baseline was reliable enough for decision-making, I evaluated the markets individually.

For the Netherlands, France, Austria and the other opportunities under consideration, I looked at the combination of:

→ Existing customer demand
→ Current paid-media performance
→ Search/category opportunity
→ Audience potential
→ Product-market response
→ Competitive intensity
→ Acquisition economics
→ Conversion behaviour
→ Existing market penetration
→ Potential scale
→ Remaining headroom

This was where the distinction between performance and opportunity became important.

Germany could still have the strongest historical numbers.

That didn't automatically mean Germany had the greatest remaining opportunity for the next level of investment.

Likewise, a smaller European market didn't need to outperform Germany today to become an attractive place to scale tomorrow.

I Planned Media Differently for Each Market

Once I had a clearer view of the opportunity, I translated it into market-specific media plans.

I didn't copy the German account structure and change the language.

I looked at the role paid media needed to perform in each market.

Media Planning

I worked through:

→ Market-level investment
→ Channel allocation
→ Demand capture versus demand creation
→ Funnel role
→ Audience strategy
→ Product/category priorities
→ Prospecting versus remarketing
→ Web versus app acquisition where relevant
→ Test budgets
→ Budget phasing
→ Scaling thresholds

The resulting media mix could differ considerably.

A market with meaningful existing search demand could justify stronger Search and Shopping coverage.

Another market might need more prospecting through Paid Social before demand capture could reach meaningful scale.

A larger but less-developed market might need broader demand creation.

And an adjacent market with strong existing signals might justify faster progression from testing into acquisition.

Then I Took the Plan Into Media Buying

The engagement wasn't limited to recommending what the client should do.

I was involved in turning those decisions into actual market activity.

Depending on the market and objective, the activation covered areas such as:

→ Paid Search
→ Shopping
→ Paid Social
→ Display
→ Programmatic
→ Online Video
→ Retargeting
→ App acquisition
→ App re-engagement

I worked across:

→ Campaign architecture
→ Bidding
→ Budget pacing
→ Audience activation
→ Geographic targeting
→ Product feeds
→ Product/category prioritisation
→ Prospecting
→ Remarketing
→ Creative requirements
→ Localization

The media buying itself became part of the expansion analysis.

Because once real investment started flowing into a market, I could stop asking what customers might do.

I could measure what they actually did.

Localization Was Part of Performance

The German proposition gave me a starting point.

It didn't give me permission to assume that the same message, product emphasis or creative approach would work everywhere.

I looked at:

→ Local messaging
→ Creative response
→ Product propositions
→ Promotional behaviour
→ Product/category demand
→ Landing-page alignment
→ Feed requirements
→ Local customer expectations

What worked in Germany became a hypothesis.

Customer response in each market determined whether that hypothesis survived.

That mattered because weak performance in a new market doesn't automatically mean weak demand.

Sometimes the media isn't the problem.

Sometimes the proposition, localization, landing experience or product emphasis simply isn't right yet.

I Used Controlled Media Investment to Test the Expansion Opportunity

The client couldn't put substantial budgets behind every European market simultaneously and wait to see what happened.

So I built the expansion around progressive investment.

Plan

↓

Buy

↓

Measure

↓

Learn

↓

Reallocate

↓

Scale

The first objective wasn't maximum revenue.

It was decision-quality evidence.

I wanted enough investment in each priority market to understand whether the existing demand signals could translate into scalable customer acquisition.

I monitored:

→ New-customer acquisition
→ CAC / CPA
→ ROAS
→ CVR
→ Revenue response
→ Product/category performance
→ Audience response
→ Creative response
→ Web behaviour
→ App behaviour
→ Customer-quality signals where available

But I wasn't only interested in the number each metric produced.

I was interested in what happened to those numbers when I increased investment.

The Question Became: What Happens to the Next Euro?

This was one of the most important parts of the engagement.

Historical averages could tell me how a market had performed.

Expansion required me to understand marginal performance.

When I increased investment:

→ Did CAC remain commercially viable?

→ Did additional spend continue producing new customers?

→ Did revenue continue growing with investment?

→ Did CVR hold?

→ Did audience saturation begin appearing?

→ Was there still meaningful search and category demand available?

→ Did we need to create more demand rather than simply capture what already existed?

→ Were particular products or categories becoming local growth engines?

This is where a market with a smaller existing contribution could suddenly become much more interesting.

It might not have Germany's historical scale.

But if it continued responding strongly as investment increased, it could have something extremely valuable:

more remaining growth headroom.

Germany, the Netherlands, France and Austria Began Playing Different Roles

As the data developed, I stopped thinking about the markets as competitors on one performance leaderboard.

They were at different stages.

Germany

Germany remained the established commercial engine and the benchmark for mature paid-media performance.

The objective was to protect that position while continuing to identify incremental opportunities.

Netherlands

The Netherlands provided an opportunity to understand how far an underdeveloped but promising market could move when investment became more deliberate.

The focus became validating scalability rather than simply comparing its current revenue with Germany.

France

France represented a larger potential market, but one that required its own approach to localization, proposition, audiences and demand development.

Its absolute potential couldn't be judged from early acquisition efficiency alone.

Austria

Austria represented a natural adjacent opportunity, but its smaller market size meant that strong efficiency still needed to be considered alongside its absolute growth ceiling.

The question therefore wasn't:

Which country wins?

It was:

What role should each market play in the client's next stage of European growth?

Web and App Behaviour Changed How I Read the Media Performance

The customer journey wasn't always:

Ad → Website → Purchase

Customers could move across several touchpoints.

Paid Social → Website → App Install → App Purchase → CRM → Repeat Purchase

or:

Shopping → Website → Retargeting → App → Purchase

That mattered when I was deciding where to put additional investment.

A platform could report one version of the conversion.

Analytics could show another.

The eventual customer relationship could tell a different story again.

So I connected paid-media performance with the broader signals available across:

→ Web behaviour
→ App behaviour
→ Analytics
→ CRM/customer data where available
→ Product performance
→ Revenue
→ New-customer acquisition
→ Repeat behaviour
→ Customer-value signals

This helped me avoid making expansion decisions entirely from whichever platform happened to claim the final conversion.

The Client Expanded in Stages

The initial market recommendation wasn't where the engagement ended.

It was where the real scaling work began.

The client progressively increased its presence in the markets where the evidence justified doing so.

Germany remained the established base

↓

Existing European demand was assessed

↓

Priority markets received controlled investment

↓

Acquisition was validated

↓

Media plans changed based on actual behaviour

↓

Budgets increased selectively

↓

Performance was measured again

↓

Investment moved toward stronger incremental opportunities

↓

Selected markets progressed from limited presence toward meaningful scale

Months 1–2: Proving the Opportunity

The early phase focused on validation.

I wanted to understand:

→ Which markets could generate sustainable acquisition
→ Which channels produced meaningful demand
→ Which audiences responded
→ Which products travelled well across markets
→ Where localization needed improvement
→ How web and app customers behaved
→ Whether the measurement was giving me a consistent picture

The initial market assessment gave me hypotheses.

The first weeks of media buying started challenging them.

And that was exactly what I wanted.

Months 2–3: I Started Reallocating the Investment

As the evidence developed, I changed the original allocations.

I increased investment where customer acquisition remained healthy.

I held or reduced investment where the data wasn't yet strong enough.

I rebalanced:

→ Markets
→ Channels
→ Audiences
→ Products/categories
→ Prospecting and remarketing
→ Web and app activity
→ Campaign budgets

The media plan wasn't a document I created at the beginning and followed for six months.

The buying generated new evidence, and that evidence continuously changed the plan.

Months 3–4: Scaling Became the Test

Once a market demonstrated enough potential, I increased investment progressively.

The operating rhythm became:

Increase → Observe → Measure → Adjust → Increase again

At this point, I wasn't trying to prove that the market could generate conversions.

I was trying to establish how far it could scale before the economics materially changed.

I continued watching:

→ Customer acquisition
→ CAC / CPA
→ ROAS
→ CVR
→ Revenue
→ Audience saturation
→ Product/category growth
→ New-customer contribution
→ Web/app behaviour
→ Customer-quality signals

A market working at a small test budget wasn't enough.

I wanted to understand how it behaved when it started receiving meaningful investment.

Months 4–6: From Campaign Scaling to Market Scaling

By the later stages of the engagement, I was no longer simply reallocating money between campaigns.

I was making investment decisions across several levels:

Market

↓

Channel

↓

Audience

↓

Product / Category

↓

Campaign

↓

Geography

With a multi-million-euro paid-media investment across the wider activity, even relatively small percentage reallocations represented meaningful commercial decisions.

The question increasingly became:

Where should the next portion of growth budget go?

If one market continued showing healthy incremental economics, I could increase its share.

If another began showing signs of saturation, I could slow the investment.

If a channel stopped contributing efficiently, I could move budget elsewhere.

If customer behaviour suggested that a market deserved more investment despite a slightly higher initial CAC, I could factor that into the decision.

This was media optimization at the level of business growth allocation, not simply campaign management.

I Could Finally Look Beyond the First Purchase

Six months also gave me something the initial market tests couldn't:

time to understand the customers being acquired.

As customer cohorts developed, I could increasingly evaluate:

→ New versus returning customers
→ Repeat purchase behaviour
→ Average order behaviour
→ Product/category development
→ Web versus app engagement
→ Retention signals
→ Customer quality

That sometimes changed how attractive a market looked.

A market with a higher initial acquisition cost could still be commercially interesting if it produced stronger customers.

Likewise, cheap first purchases didn't automatically mean high-quality growth.

The expansion strategy therefore continued evolving as customer behaviour matured.

The Media Mix Evolved With Each Market

The media strategy used to develop a market didn't remain static.

Early-stage markets could initially focus on:

Capture demand → Acquire customers → Learn

As confidence increased:

Expand audiences → Build demand → Increase reach → Scale acquisition

And as the customer base developed:

Re-engage → Strengthen app and CRM relationships → Drive repeat purchase → Increase customer value

Each market moved through those stages differently.

That was another reason I never treated European expansion as one German media strategy translated into multiple languages.

The Results

By the end of the six-month engagement, the client had moved beyond simply having scattered demand outside Germany.

Selected European markets had progressed from relatively limited presence into structured, measurable and scalable growth activity.

Media Scale

→ Multi-million-euro paid-media investment managed across the wider activity

→ Multiple European markets moved through structured test, validation and scaling stages

→ Market-level budgets progressively reallocated based on actual customer and commercial performance

→ Web + App incorporated into the wider acquisition and measurement approach

Campaign Performance

→ ROAS maintained at commercially sustainable levels while investment increased

→ CAC / CPA controlled through progressive scaling rather than unrestricted budget increases

→ CVR improved through market-specific media, product, creative and customer-journey optimization

→ New-customer acquisition expanded beyond the established German market

Business Growth

→ European revenue contribution increased as selected markets moved beyond limited presence

→ Customer acquisition diversified beyond Germany

→ Priority expansion markets developed into meaningful commercial contributors

→ The business established a repeatable model for evaluating and scaling further European opportunities

Six Months Later, the Business Had More Than Campaigns Running in More Countries

That was never the real goal.

The client now had a clearer understanding of:

→ Which markets could absorb additional investment
→ Which channels played different roles by market
→ What acquisition economics remained sustainable at greater scale
→ Which products and categories drove local demand
→ Where customer quality justified further investment
→ How web and app behaviour influenced acquisition
→ Which markets still had meaningful headroom
→ Which markets required more development
→ How future growth budget could be allocated based on evidence rather than assumptions

The engagement had started with a German eCommerce business already seeing some demand elsewhere in Europe.

Six months later, selected markets were no longer simply international traffic and occasional customers.

They had become part of a structured European growth strategy.

What This Engagement Changed in the Way I Look at European Market Expansion

This experience reinforced something that has stayed with me throughout my work in multi-market performance marketing.

I don't treat countries as a ROAS leaderboard.

For me, the stronger view is:

Measurement Confidence

↓

Customer Demand

↓

Current Performance

↓

Media Scalability

↓

Customer Economics

↓

Remaining Growth Headroom

↓

Business Readiness

Germany gave me the benchmark.

The Netherlands, France, Austria and the other European markets gave me the evidence.

My role over those six months was to turn that evidence into action: assess the opportunity, plan and buy the media, measure the customer response, change the allocation, scale what worked and continuously test whether that growth remained commercially sustainable.

The market performing best today tells me where a business has already built something valuable.

For market expansion, the more important question is:

Where can the next stage of investment create the strongest sustainable growth?

 

Connected TV (CTV) in the Media Mix: What Happens When Premium Reach Meets Performance Across Germany & Europe?

 

For years, media planning had a relatively clear separation.

Premium video was largely about reach, attention and brand building.

Performance media was expected to target, measure, optimise and deliver measurable business outcomes.

Connected TV (CTV) is making that separation increasingly difficult to maintain.

Not because CTV has suddenly turned the biggest screen in the home into another performance placement.

And not because every CTV impression should be expected to produce an attributable conversion.

What makes CTV interesting is that many of the characteristics associated with premium video now sit alongside capabilities performance marketers know well:

→ Audience-informed buying
→ Programmatic activation
→ First-party data
→ Frequency management
→ Cross-device measurement
→ Experimentation
→ Commerce and Retail Media data
→ Stronger connections to business outcomes

For advertisers across Germany and Europe, that creates an interesting question:

What happens when premium reach starts operating inside a media environment increasingly expected to demonstrate performance?

CTV Doesn't Need to Do the Same Job as Paid Search

A performance-led media mix doesn't mean every channel should be pushed toward the final conversion.

Different channels have different jobs.

Paid Search can be exceptionally effective at capturing existing intent.

Paid Social can create and capture demand across highly scalable audience environments.

Retail Media can reach consumers close to commerce and purchase decisions.

Digital Out-of-Home (DOOH) can create visibility across physical environments.

CTV brings something different.

It gives advertisers access to a premium, large-screen video environment, while adding targeting, buying and measurement capabilities that were historically more associated with digital media.

That makes its potential role broader than simply generating awareness.

Depending on the business objective, CTV can contribute to:

→ Building broad or targeted reach
→ Reaching audiences incrementally beyond other video activity
→ Creating demand before someone actively searches
→ Introducing products or propositions that benefit from storytelling
→ Reinforcing consideration
→ Supporting product launches and market expansion
→ Working alongside lower-funnel channels that capture subsequent demand

The important question isn't:

“Can CTV generate conversions?”

Of course conversions may happen after CTV exposure.

The better question is:

“What job are we asking CTV to perform within the overall media strategy?”

That decision should come before choosing the KPI.

CTV Isn't Simply Another Online Video Placement

It is tempting to put CTV into the same bucket as every other form of digital video.

But the viewing environment matters.

Someone watching premium content on a television screen is in a different situation from someone scrolling through a mobile feed or watching a short video on a laptop between browser tabs.

The differences can include:

→ Screen size
→ Viewing distance
→ Viewing duration
→ Content environment
→ Household viewing
→ Attention and interruption patterns
→ Creative experience

That has implications for both media planning and creative.

A six-second social asset doesn't automatically become a strong CTV advertisement simply because it can technically be delivered to a television screen.

The creative has more space to tell a story, demonstrate a product, communicate a proposition or build memory.

At the same time, the media investment needs to consider whether CTV is actually adding something the advertiser isn't already getting elsewhere.

That makes incremental reach and frequency particularly important.

If the same household is already being heavily exposed through other video activity, adding more impressions isn't necessarily adding more value.

The question becomes:

Who are we reaching through CTV that we weren't reaching effectively before, and what does that exposure contribute?

This Is Where Performance Starts Entering the Conversation

CTV becomes particularly interesting when the premium viewing environment is combined with more sophisticated media capabilities.

Advertisers can increasingly work with:

→ Audience segments
→ First-party customer data
→ Programmatic buying
→ Geographic and contextual signals
→ Frequency controls
→ Cross-device relationships
→ Experimentation
→ Retail and commerce audiences
→ Exposure and outcome measurement

That changes the planning conversation.

Instead of buying premium reach and evaluating it almost entirely through delivery metrics, advertisers can start asking more detailed questions.

Which audiences are we reaching?

Are we reaching new households or repeatedly reaching the same ones?

What happens after exposure?

Does Search activity change?

Does website or app behaviour change?

Do exposed audiences purchase differently?

Does CTV create incremental customers or revenue?

This doesn't turn CTV into Paid Search.

It makes premium reach more accountable.

And that distinction matters.

First-Party and Commerce Data Make the Story More Interesting

For Retail, eCommerce and D2C businesses, another layer is emerging.

CTV doesn't necessarily have to operate separately from customer and commerce intelligence.

Depending on the activation environment and available partnerships, audience strategy can increasingly connect with:

→ CRM audiences
→ Existing versus prospective customers
→ Product/category purchasers
→ Customer-value segments
→ Retail Media audiences
→ Purchase behaviour
→ Other permitted first-party signals

Imagine an eCommerce retailer preparing for Back-to-School.

The business doesn't necessarily need to reach every household equally.

It may want to build reach among relevant prospective customers, suppress existing customers from particular acquisition activity, communicate different product propositions to different audience groups or understand whether CTV exposure ultimately influences purchasing behaviour.

That brings CTV closer to the way performance marketers already think:

Audience → message → exposure → behaviour → business outcome

But there is still an important difference.

The customer doesn't necessarily respond on the television.

The journey often continues somewhere else.

The Television Screen May Start the Journey, Not Finish It

Imagine someone watching CTV at home.

They see an advertisement for a German eCommerce retailer's Back-to-School collection.

They don't click anything.

They don't scan a QR code.

They don't immediately visit the website.

Nothing happens that would make a conventional performance dashboard particularly excited.

Later that evening, they pick up their phone and search for the retailer.

The next day, they see a Paid Social ad.

Two days later, they search for a specific backpack, click a Paid Search advertisement and purchase.

The reporting might say:

Paid Search generated the conversion.

Technically, that may be correct within the attribution model being used.

But it doesn't answer a more important question:

What created the demand that Search eventually captured?

This is why CTV becomes particularly interesting when it is evaluated as part of the whole media system, rather than as an isolated channel.

Germany & Europe Add Another Layer

There is another reason CTV needs to be considered carefully across Germany and wider Europe.

Europe isn't one homogeneous media market.

Viewing behaviour, broadcaster ecosystems, streaming adoption, inventory availability, measurement capabilities and commercial partnerships can differ significantly between countries.

Germany itself has a combination of broadcasters, streaming environments, device ecosystems and advertising technology relationships that advertisers need to navigate.

Move into France, Italy, Spain, the Netherlands or other European markets and the environment changes again.

That affects:

→ Available inventory
→ Audience scale
→ Addressability
→ Programmatic access
→ Measurement capabilities
→ Data availability
→ Privacy considerations
→ Creative and language requirements
→ Local viewing behaviour

A European advertiser therefore shouldn't assume that a CTV strategy designed for one market can simply be copied across every other market.

The business objective may remain consistent, but media planning and measurement need to reflect local realities.

So How Should CTV Actually Be Measured?

Once CTV's job in the media mix is clear, measurement becomes much more meaningful.

It helps to think about measurement in layers.

Media Delivery

First, did the campaign actually deliver as intended?

Depending on the buying environment, advertisers can examine metrics such as:

→ Impressions
→ Reach
→ Frequency
→ Audience delivery
→ Completed views
→ Video completion rate
→ Cost efficiency

These metrics matter.

But they answer a delivery question, not necessarily a business question.

Incremental Reach

This becomes particularly important when CTV is part of a wider video strategy.

The business needs to understand whether CTV is:

adding new audience reach

or simply:

adding more frequency against people already being reached elsewhere.

That distinction can materially change the value of the investment.

Behaviour After Exposure

The next layer asks whether something changes after people encounter the campaign.

Depending on the measurement setup, advertisers might examine:

→ Branded Search behaviour
→ Direct traffic
→ Website visits
→ App activity
→ Product/category engagement
→ Store behaviour
→ Other downstream actions

This starts connecting media exposure with customer behaviour.

But there is still a difference between observing behaviour after exposure and proving that the exposure caused it.

Commercial Outcomes

For an eCommerce or Retail advertiser, the analysis can go further:

→ Purchases
→ Revenue
→ New customers
→ Customer acquisition
→ Product/category sales
→ Customer value
→ Offline sales where relevant

CTV can therefore become connected to commercial outcomes.

But again, connection isn't automatically causation.

That takes us to the most important measurement layer.

Incrementality

The strongest question isn't simply:

“How many conversions happened after someone saw our CTV campaign?”

It is:

“How many additional conversions happened because we ran the CTV campaign?”

That may require:

→ Holdout groups
→ Exposed versus suitable control audiences
→ Geographic experiments
→ Matched-market analysis
→ Lift studies
→ Other appropriate experimental approaches

The exact methodology will depend on the platform, market, campaign and available measurement infrastructure.

But the principle remains the same.

Attributed conversions tell us what happened after exposure. Incrementality tries to tell us what happened because of the advertising.

More Measurable Doesn't Mean Perfectly Attributable

CTV's increasing measurability creates an interesting risk.

The more data advertisers receive, the easier it becomes to believe that every customer journey can be reconstructed precisely.

Reality is messier.

A customer might encounter:

CTV → DOOH → Paid Social → Search → Website → CRM → Purchase

Another customer might see:

CTV → Direct Visit → Purchase

Another might see the advertisement several times and buy three weeks later.

Trying to assign perfect credit across every interaction can create an illusion of precision.

That doesn't mean attribution is useless.

It means attribution should be one piece of evidence rather than the entire business case.

For CTV, the combination of delivery, incremental reach, behavioural signals, commercial outcomes and controlled experimentation can provide a much more useful picture.

Imagine a Back-to-School Campaign Across Germany

Consider a fictional German eCommerce retailer preparing for the Back-to-School season.

The company sells backpacks, stationery, laptops, desk accessories and other school-related products.

It is already running Paid Search, Paid Social, CRM and Online Video.

For the new campaign, it adds CTV and DOOH.

Each channel has a different job.

CTV

CTV introduces the Back-to-School proposition through premium video and builds reach among relevant households.

The creative has enough time and space to show the wider product range rather than simply promote one SKU.

DOOH

DOOH creates physical visibility around selected urban, shopping and transport environments.

Programmatic activation can add location, timing and contextual relevance.

Paid Search

Search captures active demand when customers begin looking for brands, categories and individual products.

Paid Social

Social continues the conversation through product, creative and audience-led campaigns across personal devices.

CRM

Existing customers receive relevant Back-to-School communication based on the relationship the retailer already has with them.

Now imagine a customer sees the CTV campaign on Sunday evening.

On Monday morning, they encounter the DOOH campaign during their commute.

On Tuesday, they search for one of the advertised product categories.

Later, they encounter a Social ad.

On Wednesday, they purchase.

The objective shouldn't be to spend days arguing about whether CTV, DOOH, Search or Social deserves the sale.

The more valuable question is whether the combined media strategy generated additional demand, customers and revenue.

Measuring the Campaign as a Media System

The retailer can still evaluate each channel individually.

CTV should deliver the reach, frequency and audience quality expected from the investment.

DOOH should deliver against its planned locations, audiences and contextual opportunities.

Search should capture relevant demand efficiently.

Social should deliver against its audience and campaign objectives.

But the business can also create a measurement design that looks across the media mix.

For example, comparable geographic markets could receive different combinations of activity:

Market A: Existing media activity

Market B: Existing media + CTV

Market C: Existing media + DOOH

Market D: Existing media + CTV + DOOH

With a properly designed experiment, the retailer can investigate:

→ What incremental effect did CTV create?
→ What incremental effect did DOOH create?
→ What happened when both were present?
→ Did Search demand change?
→ Did new-customer acquisition change?
→ Did total Back-to-School revenue change?
→ Did the combined media investment produce more incremental value than the existing mix alone?

Now the conversation moves beyond:

“What was the CTV ROAS?”

and toward:

“What did adding CTV actually do to the economics of the overall media plan?”

That is a much more useful business question.

CTV Should Work With the Media Mix, Not Compete Against It

There is a temptation in performance marketing to make channels compete against one another.

Search generated this many conversions.

Social generated that many.

CTV delivered this reach.

DOOH delivered those impressions.

Then budgets are moved toward whichever dashboard appears to show the strongest immediate return.

But customers don't experience advertising as separate reporting columns.

They move between screens, devices, platforms and physical environments.

CTV may create demand that Search captures.

DOOH may reinforce something first seen on CTV.

Paid Social may continue a product story.

Retail Media may influence the decision close to purchase.

CRM may finally convert an existing customer.

The job of media planning is therefore not simply to identify which channel wins.

It is to understand what each channel contributes and whether the combination produces a stronger business outcome.

So, What Happens When Premium Reach Meets Performance?

CTV doesn't stop being a premium reach environment simply because advertisers can measure more of what happens around it.

And it doesn't need to become another direct-response channel.

What changes is the level of accountability surrounding that reach.

Advertisers can increasingly ask:

→ Who did we reach?

→ Did CTV add incremental reach?

→ What happened after exposure?

→ Did demand change?

→ Did customer behaviour change?

→ Did commercial outcomes change?

→ And most importantly, did CTV create incremental value that would not otherwise have happened?

That is where premium reach and performance start to come together.

Not by forcing CTV to behave like Paid Search.

But by giving premium video a clearer role inside a media strategy where reach, audience, creative, customer behaviour and business outcomes can increasingly be considered together.

For advertisers across Germany and Europe, that makes the question around CTV much more interesting than whether it belongs to the brand or performance budget.

The better question is:

What job should CTV perform in the media mix, what should it work alongside, and what evidence will tell us whether that investment actually made the overall media strategy stronger?

 

Digital Out-of-Home (DOOH) Beyond Awareness: What Role Should It Play in a Performance-Led Media Mix Across Germany & Europe?

 

For a long time, the role of Out-of-Home advertising was relatively easy to understand.

Put a strong message in a high-traffic location. Build visibility. Reach people as they move through cities, transport hubs, shopping districts and other public spaces.

That role still matters.

But Digital Out-of-Home (DOOH) now deserves a broader conversation.

Not because it has suddenly become another direct-response channel. And not because every screen exposure can now be connected neatly to a conversion.

The more interesting change is that DOOH can increasingly combine the physical presence of Out-of-Home with capabilities performance marketers are familiar with:

→ Data-informed planning
→ Programmatic activation
→ Audience and contextual signals
→ Dynamic creative
→ Flexible buying
→ More sophisticated measurement

For businesses across Germany and Europe, that raises a bigger question:

What role should DOOH actually play in a performance-led media mix?

Performance-Led Doesn't Mean Every Channel Has to Behave Like Paid Search

One of the easiest mistakes in modern media planning is judging every channel by the same standard.

Search is extremely effective at capturing expressed demand.

Paid Social can create and capture demand across scalable audience environments.

Retail Media can connect advertising closely with commerce.

Connected TV (CTV) brings premium video into increasingly addressable and measurable environments.

DOOH does something different.

It can put a brand into the physical environments where customers actually live, commute, shop, travel and spend their time.

Across Germany, that could mean:

→ Urban centres
→ Railway and transit environments
→ Airports
→ Shopping districts and malls
→ Retail locations
→ Business districts
→ Leisure and entertainment environments

The same opportunity exists across wider Europe, but the cities, mobility patterns, media environments and customer behaviour can be very different.

The value of DOOH is therefore not simply that it adds another digital screen to the media plan.

It creates a connection between digital media strategy and the physical world.

And in a performance-led media mix, that can be a very different job from capturing the final click.

The Role of DOOH Has Expanded

The screen may exist in the physical world, but the way advertisers can plan and activate against it has changed considerably.

Programmatic Digital Out-of-Home (pDOOH) is an important part of that development.

Instead of every campaign being defined entirely by fixed placements and long booking periods, programmatic buying can provide greater flexibility around where and when advertising runs, while allowing location, audience and contextual information to influence activation.

That opens the door to more interesting decisions.

→ Location: Which environments are commercially relevant?

→ Time: When does that environment become most valuable?

→ Audience: What audience patterns are associated with that location?

→ Context: What is happening around the screen?

→ Weather: Does the product become more relevant under particular conditions?

→ Events: Is there a moment when audience concentration or relevance changes?

→ Proximity: Is the customer close to a store, dealership, restaurant, venue or another commercial location?

→ Creative: Should the message or product change depending on the situation?

The important shift isn't simply from manual buying to automated buying.

It is the ability to think beyond where a screen is located and consider when, why and under what circumstances that location becomes commercially relevant.

Context Can Make the Same Screen a Different Media Opportunity

Consider a digital screen near a major German railway station.

At 7:30 on a weekday morning, it may be surrounded largely by commuters.

On Friday evening, the audience, journey and mindset may look very different.

During a major trade fair, football match or cultural event, the same location can take on another commercial meaning.

Weather adds another dimension.

A food-delivery brand may find particular conditions relevant.

A fashion retailer could change the products it promotes as temperatures change.

A travel company may adapt its proposition around seasonality or destination demand.

A retailer could emphasize a nearby store or promotion.

An automotive advertiser could use different creative around relevant mobility environments.

This doesn't mean every DOOH campaign needs dozens of triggers.

Sometimes broad reach is exactly the job DOOH needs to perform.

The point is that advertisers can increasingly have more control over the circumstances in which that reach occurs.

That makes context part of the media decision.

Creative Has to Respect the Environment

There is another difference that becomes important when performance marketers work with DOOH.

The creative isn't being consumed on a phone held 30 centimetres from someone's face.

Someone may be:

→ Walking through a station
→ Driving past a roadside screen
→ Waiting for public transport
→ Moving through an airport
→ Shopping inside a retail environment
→ Seeing the message from considerable distance

Screen size, viewing distance, movement, dwell time and surrounding environment all influence what the creative needs to accomplish.

That means a successful Paid Social or Display asset shouldn't automatically become a DOOH asset simply by resizing it.

Dynamic Creative Optimisation (DCO) can make the message more relevant to location, time, weather, events, product availability or other contextual conditions.

But greater creative flexibility doesn't mean greater complexity.

Sometimes the strongest DOOH creative is still the simplest: one clear message that makes sense in that particular environment and can be understood quickly.

Germany & Europe Are Not One DOOH Market

For brands operating internationally, this distinction matters.

A campaign across Germany, France, the Netherlands, Spain or Italy may share a strategic objective, but the media environment around it can differ substantially.

Different markets can have:

→ Different DOOH inventory and screen environments
→ Different audience measurement approaches
→ Different public transport and mobility patterns
→ Different levels of programmatic availability
→ Different data and measurement ecosystems
→ Different privacy and regulatory considerations
→ Different relationships between city centres, retail and transportation
→ Different consumer behaviour

Even within Germany, Berlin is not Munich, and Frankfurt is not Hamburg.

A European DOOH strategy therefore shouldn't simply be a centrally designed campaign replicated screen-for-screen across countries.

The business objective can remain consistent while planning, activation, creative and measurement reflect local market realities.

That becomes particularly important when DOOH is part of a wider European media strategy rather than a standalone awareness campaign.

Before Comparing CPMs, What Does a DOOH Impression Actually Mean?

This is where DOOH becomes technically different from many other digital channels.

A Display ad served to a browser or device and a DOOH ad shown on a public screen do not represent exposure in the same way.

A DOOH screen may be visible to multiple people during a single ad play.

That is why audience estimates and impression multipliers matter.

At a simplified level:

One ad play does not automatically equal one impression.

The impression multiplier estimates the average audience associated with an ad play using available audience information such as traffic or footfall, dwell time and presence within the relevant exposure environment.

Depending on the measurement methodology, there can also be an important distinction between someone being present within the potential viewing area, having an Opportunity to See (OTS) the screen, and more refined estimates of Likelihood to See (LTS).

That sounds like a technical detail.

It isn't.

It affects how advertisers interpret:

→ Impressions
→ CPM
→ Reach
→ Frequency
→ Audience delivery
→ Cross-channel comparisons

This is why putting a DOOH CPM next to a Display or Paid Social CPM and assuming the numbers mean exactly the same thing can be misleading.

The metrics may share the same names.

The underlying exposure is not necessarily being measured in the same way.

Measurement Should Follow the Job DOOH Is Supposed to Do

There shouldn't be one universal DOOH KPI.

Measurement should follow the role the medium was asked to perform.

If the objective is reach and visibility

The relevant questions may include:

→ How much of the intended audience did the campaign reach?
→ At what frequency?
→ In which locations and environments?
→ How efficiently was that audience delivered?

If the objective is building demand

The business may look further:

→ Brand awareness or consideration
→ Search behaviour
→ Branded search activity
→ Direct traffic
→ Other indicators of changing demand

If DOOH supports physical retail

Additional questions become possible:

→ Did visitation patterns change?
→ Did activated locations behave differently?
→ Did store-level sales show a meaningful change?
→ Can results be compared with suitable control locations?

If DOOH supports customer acquisition

The business can examine subsequent digital and commercial behaviour where the measurement design allows it.

And when the investment becomes significant, perhaps the most useful question is:

Did DOOH create an outcome that would not have happened without the investment?

That moves the conversation from attribution toward incrementality.

More Measurable Doesn't Mean Perfectly Attributable

Digital advertising has created an expectation that every advertising interaction should somehow receive a precise conversion value.

DOOH doesn't fit neatly into that model.

Someone can see an advertisement while walking through a railway station and search for the brand hours later.

Another person may see the same campaign repeatedly across different locations before visiting a store.

Someone else may encounter DOOH, CTV, Paid Social and Search before eventually purchasing.

Assigning that conversion to one screen exposure can create a level of precision the customer journey simply doesn't support.

That doesn't make DOOH unmeasurable.

It means measurement needs to be designed around the question being asked.

Depending on the campaign, that might involve:

→ Geographic testing
→ Exposed vs control analysis
→ Brand or search lift
→ Footfall analysis
→ Sales analysis
→ Digital behaviour
→ Incrementality studies
→ Market-level comparisons

The objective isn't to manufacture a perfect attribution number.

It is to build enough evidence to make a better investment decision.

Where DOOH Meets Retail Media

There is another development worth watching, particularly for Retail, FMCG and omnichannel businesses.

DOOH increasingly overlaps with the expanding Retail Media ecosystem.

Digital screens can exist:

→ Inside stores
→ Around shopping centres
→ Near points of purchase
→ Across retail environments
→ Along the physical journey leading to a store

That creates an interesting connection between media exposure, shopper context and commerce data.

A retailer may have information about products, promotions, inventory and customer behaviour. DOOH adds a physical-media layer that can potentially activate some of that intelligence close to the shopping environment.

For example, the question can move from:

“Which advertisement should appear on this screen?”

to:

“Which product or proposition makes the most commercial sense in this location, at this moment, given the wider retail context?”

That brings DOOH closer to merchandising, Retail Media and commerce strategy without requiring it to become a direct-response channel.

Imagine a German Retailer Putting This Into Practice

Consider a fictional German omnichannel sports retailer operating stores and eCommerce across several European markets.

The company is launching a new running collection in Germany.

Instead of treating DOOH as a standalone awareness buy, it builds the campaign around the role DOOH should play within the wider launch.

1. Start With the Business Objective

The company wants to:

→ Build awareness for the new collection
→ Increase consideration among urban runners
→ Generate demand around selected product categories
→ Support stores in Berlin, Hamburg, Cologne and Munich
→ Grow both online and offline sales

DOOH isn't expected to achieve all of this alone.

Its job is to create high-visibility physical presence around relevant urban environments.

2. Add Context to the Media Plan

The company identifies environments where the audience and business opportunity overlap:

→ Commuter locations
→ Areas around selected retail stores
→ Running and leisure environments
→ Relevant transport hubs
→ Locations associated with major sporting events

Programmatic activation provides additional flexibility around timing and context.

Creative can also adapt.

A screen near a store can highlight local availability.

Weather conditions can influence which products are featured.

A relevant sporting event can trigger a different proposition.

The campaign still delivers reach.

But the reach now has commercial context around it.

3. Connect DOOH With the Wider Media Mix

At the same time:

→ Paid Search captures active product and brand demand
→ Paid Social continues the product story across personal screens
→ Online Video builds additional reach and product consideration
→ CRM activates existing customers
→ Stores provide the physical purchase experience
→ eCommerce captures digital demand

DOOH isn't competing with those channels for the same job.

It is contributing something different to the same commercial objective.

4. Measure More Than Screen Delivery

The company still measures reach, frequency and audience delivery.

But it also examines:

→ Changes in branded and category search behaviour
→ Website and product activity in relevant markets
→ Store visitation patterns where suitable measurement is available
→ Online and offline sales trends
→ Differences between activated and comparison geographies
→ New-customer acquisition
→ Incremental business impact where the campaign design allows it

The objective isn't to prove that one particular screen generated one particular sale.

It is to understand whether the combined media strategy created additional business value.

DOOH Works Best When It Doesn't Have to Pretend to Be Another Channel

This is perhaps the most important point.

DOOH doesn't need to become Paid Search.

It doesn't need to become Paid Social.

And it doesn't need to produce a clickable conversion path to justify its existence.

Its strength comes from doing something those channels cannot replicate in exactly the same way:

Creating visible brand presence in the physical environments where people move through their everyday lives.

What has changed is everything that can increasingly sit around that strength.

→ Better planning
→ Programmatic activation
→ Context
→ Dynamic creative
→ Audience intelligence
→ More flexible buying
→ Stronger connections with digital channels
→ More sophisticated measurement

That doesn't transform DOOH into a conventional performance channel.

It makes DOOH more useful inside a performance-led media strategy.

So, What Role Should DOOH Play in a Performance-Led Media Mix?

DOOH doesn't need one fixed role.

Its role should depend on the business objective, customer journey and wider media strategy around it.

For some businesses, that means building broad physical visibility in markets where digital channels alone cannot create the same presence.

For others, it means supporting a product launch, strengthening presence around retail locations, reaching audiences in relevant real-world environments or creating demand that Search, Social, Retail Media and other channels can subsequently capture.

And increasingly, programmatic activation, contextual signals, dynamic creative and better measurement allow that role to become more deliberate.

The value of DOOH in a performance-led media mix can therefore sit across several areas:

→ Building reach and physical-market presence

→ Creating and reinforcing demand

→ Connecting digital campaigns with real-world customer environments

→ Supporting retail, product launches and geographic growth

→ Adding relevance through location, timing and real-world context

→ Working alongside Search, Social, CTV, Retail Media and other channels rather than competing with them for the same job

→ Contributing measurable evidence towards wider business outcomes

The important distinction is that performance-led does not mean every channel must become a performance channel.

It means every media investment should have a clearly defined role, an appropriate way of measuring that role and a reason for being part of the overall growth strategy.

DOOH doesn't need to generate the final click to create business value.

Its opportunity lies in combining something digital advertising often struggles to replicate, visible presence in the physical world, with increasingly sophisticated planning, activation, context and measurement.

So perhaps the question for businesses across Germany and Europe is no longer simply:

“Should DOOH be in the media plan?”

It is:

“What job do we need DOOH to perform, how does it work with the rest of our media, and how will we know whether it created incremental value?”

That, ultimately, is where DOOH belongs in a performance-led media mix.
