Media Planners & Buyers: ChatGPT Just Became Measurable

€2.8–€4.6 CPCs and Ads Manager rollout bring real ROI conversations into play

For media planners and buyers, ChatGPT is no longer just an interesting AI tool sitting outside the media plan.

It is starting to look like a real performance channel.

OpenAI’s move from a mainly impression-led model toward CPC ads changes the conversation. Until now, ChatGPT advertising looked closer to an early branding environment. Useful for testing visibility, but harder to compare directly with performance channels.

With CPC pricing now being tested, advertisers can finally think in a familiar framework:

• What did I pay?
• What did I get?
• How does it compare with Google Search, YouTube, Display, or PMax?

That shift alone moves ChatGPT from “experimental” to “comparable.”

Why the CPC shift matters

The reported CPC range of around €2.8 to €4.6 per click is critical because it gives something tangible to benchmark against existing channels.

It also explains the timing.

ChatGPT CPMs have reportedly dropped from around €55 closer to €23. That’s a significant compression. Moving to CPC allows OpenAI to tie revenue to measurable actions instead of declining impression value.

For advertisers, this means ChatGPT is no longer just selling reach. It’s selling outcomes.

And the moment a platform does that, it starts competing directly with Google for performance budgets.

Where this fits in a real media plan

The current structure for most performance setups is still predictable:

• Search captures demand
• Paid social creates demand
• Video supports consideration
• Retargeting converts

ChatGPT doesn’t sit cleanly in any of these.

It sits between demand generation and demand capture.

Users are not typing keywords. They are explaining problems, comparing tools, asking for recommendations. That creates a different kind of entry point into the funnel.

Not pure intent like search. Not passive discovery like social.

But high-consideration interaction.

If ad placement aligns well with that moment, the quality of traffic could be strong. That’s the hypothesis that needs to be validated.

The Ads Manager signal is just as important

Until recently, advertisers were working with very limited infrastructure. Reporting was basic, often delayed, sometimes just weekly CSV-style outputs.

Now, a new Ads Manager interface is being tested.

That includes:

• Real-time campaign control
• Ability to run and optimise campaigns directly
• Better visibility into performance

This is not a small update.

This is the difference between a beta ad product and a scalable platform.

When you combine that with increasing ad inventory already being spotted from brands like Best Buy and Expedia, it’s clear monetisation is ramping up quickly.

The real challenge: proving intent

Search works because intent is explicit.

ChatGPT has to prove that conversational context can produce equally valuable clicks.

Advertisers will not treat this differently. They will benchmark:

• CPC vs Search
• Conversion rate vs Search
• Cost per lead / cost per acquisition vs existing channels

If ChatGPT cannot compete on these, budgets won’t move beyond testing.

If it can, even partially, it becomes a serious line item in performance planning.

What this means for media planners and buyers

This is not about shifting budgets overnight.

But it does change what needs to be on the roadmap:

• Testing conversational intent vs keyword intent
• Adapting messaging for recommendation-style environments
• Evaluating CPC efficiency vs Search and PMax
• Understanding how early-stage vs mid-stage intent behaves

And most importantly, getting in early before costs rise.

Because they will.

Bottom line

This is not just a new ad format.

This is the early stage of a new performance environment where intent is expressed through conversation instead of keywords.

For media planners and buyers, that means one thing:

You can’t ignore it anymore.
