What are AI Overviews

AI Overviews defined for SEO

In SEO terms, an AI Overview is a cited position that sits above the first organic link. A lower-ranked page can earn a citation even when the top result is left out. Pew Research Center found that 88% of summaries cited three or more sources, which means several pages share the slot on each query. So rank tracking now includes checking whether your page is one of the sources the summary names.

Why AI visibility matters

AI visibility matters because the summary answers the question before anyone clicks. In Pew's study of 68,879 searches, users clicked a regular result in 8% of visits when a summary appeared, against 15% when none did. Sundar Pichai, CEO of Google, told investors in July 2025 that "AI Overviews now has over 2 billion monthly users."

That's why we track mentions, share of voice, sentiment and citations in ChatGPT and Google AI Overviews, where most AI search traffic happens, with weekly prompt sets.

How Google AI Overviews work

Google builds an AI Overview by running extra searches behind your query and writing one answer from the pages those searches return. Two steps decide which pages end up cited.

What query fan-out does

Google's Search Central documentation says AI Overviews "may use a 'query fan-out' technique," which means Google runs several related searches across subtopics. In Google's own example, "how to fix a lawn that's full of weeds" fans out into searches such as "best herbicides for lawns" and "remove weeds without chemicals." The model then writes the summary from that wider pool of results.

How Google picks sources

Google picks sources from its regular search index, so a page has to be crawlable and indexed before it can be cited. Google states there are no extra requirements to appear in AI features. In our experience, the pages that get cited answer a sub-question directly, in a passage the model can quote without rewriting. That's why ranking for the fan-out queries counts as much as ranking for the main term.

What triggers an AI Overview

Long searches phrased as questions are the most frequent triggers of AI Overviews. Pew found that just 8% of short searches of one or two words produced a summary, and that share rose to 53% for searches of 10 words or more. Across all searches in March 2025, about 18% showed one. So when we test visibility, we type buyer questions as full sentences, because that's how real buyers trigger the feature.

Example of an AI Overview

For a search like "how do I get rid of weeds in my lawn without chemicals," the AI Overview opens with a two-sentence answer, then lists methods such as hand-pulling and mulching. Source cards beside the text link to the gardening pages it drew on. Pew measured the median summary at 67 words long, so the whole answer fits on one screen.

AI Overviews versus ChatGPT

AI Overviews appear inside Google results without being asked for, while ChatGPT answers only when someone types a prompt into it.

A page that wins citations in one helps in the other, but the results differ by prompt, so we track them separately. 1StopVAT, in tax and fintech, saw 10x growth in ChatGPT visibility in 7 weeks. We measured that result on ChatGPT alone.

Get cited in AI Overviews

You get cited by publishing pages that answer your buyers' real questions directly, on a site Google can crawl. We work through these steps in order:

1. 011List the real questionsWhen we run an AI visibility audit, we start from tailored buyer prompts and check which competitors get cited for each one.
2. 022Answer in the first linesPut a direct answer of 40 to 60 words under each heading, then the evidence.
3. 033Cover sub-questions sensiblyAnswer the fan-out questions inside one strong page. Google warns that pages made for every query variation violate its spam policy on scaled content abuse.
4. 044Check crawlingConfirm in Google Search Console that your key pages are indexed.
5. 055Measure every weekRun the same prompt set weekly and record whether your pages are cited.
