Advantages of New SiteLinks in google

•Visibility. The links have been boosted to full-sized text, and augmented with a green URL and one line of text snippet, much like regular search results. This increases the prominence of both the individual sitelinks and the top site overall, making them easier to find.

•Flexibility. Until now, each site had a fixed list of sitelinks that would either all appear or not appear; there was no query-specific ranking of the links. With today’s launch, sitelink selection and ranking can change from query to query, allowing more optimized results. In addition, the maximum number of sitelinks that can appear for a site has been raised from eight to 12, and the number shown also varies by query.

•Clarity. Previously, pages from your site could either appear in the sitelinks, in the regular results, or both. Now we’re making the separation between the top domain and other domains a bit clearer. If sitelinks appear for the top result, then the rest of the results below them will be from other domains. One exception to this is if the top result for a query is a subpart of a domain

•Quality. These user-visible changes are accompanied by quality improvements behind the scenes. The core improvement is that we’ve combined the signals we use for sitelinks generation and ranking -- like the link structure of your site -- with our more traditional ranking system, creating a better, unified algorithm. From a ranking perspective, there’s really no separation between “regular” results and sitelinks anymore.
