AI Overviews are AI-generated summaries that Google Search shows above the regular results for some queries, with links to the pages they draw on. Google shows them only when it judges them helpful, there are no extra requirements to appear in them, and independent data shows fewer clicks on searches that have one.
AI Overviews are AI-generated summaries that Google Search shows above the regular results for some queries, with links to the pages they draw on. Google shows AI Overviews only when it judges them helpful, so many searches never get one.
When does Google show an AI Overview?
Only when Google’s systems decide a summary adds something to the usual results. Google’s AI features documentation says they “often don’t trigger”, and that they were designed for queries where they add benefit beyond what Search already gives.
Independent data shows the pattern. Pew Research Center tracked 68,879 Google searches by 900 US adults in March 2025: 18% produced an AI summary, but that share was 8% for one- or two-word searches and 53% for searches of 10 words or more (Pew, 22 July 2025).
For a store, that means short product searches such as gold hoop earrings rarely show one, while long, question-style searches such as are gold vermeil earrings ok for sensitive ears often do. Availability is wide: Google said on 20 May 2025 that they were live in more than 200 countries and territories and more than 40 languages.
How do pages get in?
The same way they get into Google Search. Google says there are “no additional requirements to appear in AI Overviews or AI Mode”: a page must be indexed and eligible to show a snippet, and the usual SEO practices apply.
Google’s own list for these features is practical: important content in text form, good images and video where relevant, structured data that matches the visible text, and an up-to-date Merchant Center and Business Profile. It adds that you don’t need “AI text files” or special schema. The links shown come from the same index as the regular results, so a store page that ranks poorly for the underlying sub-questions is unlikely to be cited. Pew found that 88% of AI summaries cited 3 or more sources, so one answer can credit several pages, including competitors’ guides next to your product page.
Do AI Overviews reduce clicks to stores?
On average, yes, in the best public data so far. In Pew’s study, users who saw an AI summary clicked a traditional result on 8% of visits, against 15% when no summary appeared, and clicked a link inside the summary on just 1% of visits.
They were also more likely to end their browsing session: 26% of pages with a summary against 16% without. These are US browsing figures from March 2025, across all topics, not a store-specific study. Google’s own line is that clicks from pages with AI Overviews are “higher quality”. You can’t check either claim directly, because Search Console counts AI Overviews inside the “Web” search type rather than separately.
Can you keep your pages out of AI Overviews?
Yes, page by page, with Google’s preview controls: nosnippet, data-nosnippet, max-snippet or noindex. Google-Extended doesn’t do it; that token covers Gemini training, not Search.
Few stores do. In our check of 30 jewelry, fashion and beauty stores on 17 October 2026, none of the 43 homepages and product pages we fetched used nosnippet, max-snippet or data-nosnippet. Opting out also removes the page’s normal snippet, so for most stores the better move is to make each page the clearest answer to its question. Our Google AI Overviews service does that work, built on e-commerce SEO; the AI search optimization hub covers the other engines.
