Google only requires that your page is indexed and can be shown with a snippet. Beyond that, I'd bet on four things: an answer near the top of the section, coverage of the follow-up questions, mentions on the pages AI Overviews already cite, and facts that are still true. There's no special markup, file or paid route into the cited links. If AI Overviews answer your best keywords and name competitors instead of you, this is SEO work aimed at the questions an AI Overview pulls together.

How Google picks pages for AI Overviews

Google picks AI Overview sources from its normal search index: only pages it has indexed and could show with a snippet qualify. Google's own guide to AI features and your website puts it plainly: "There are no additional technical requirements."

The same guide explains how a single AI Overview gets built. Google may use a "query fan-out" technique, issuing several related searches across subtopics and data sources, then showing a wider set of supporting links than a classic results page would. So an AI Overview for one question can cite pages that rank for the sub-questions, not only the page that ranks first for the words the searcher typed.

That is why this work overlaps so much with GEO, the broader job of getting named in AI answers across ChatGPT, Gemini, Perplexity and Google. Google's version is the most SEO-shaped of them, because its AI features run on Google Search itself.

AI Overviews show up most on question-style searches. In Pew Research Center's analysis of March 2025 browsing data from 900 US adults, 60% of searches that opened with a question word produced an AI summary, compared with 8% of searches of one or two words. So start with the who, what and why queries that already bring you traffic, since that's where an AI Overview is most likely to sit above you. Google also says AI Overviews only appear when Google decides they add something beyond the classic results, so they often don't trigger at all. And when they do, Pew found people click links less often, which adds to the problem of zero-click searches.
