Google says there are no extra requirements to appear in AI Overviews or AI Mode beyond being indexed and eligible to show a snippet. This guide covers how sites appear, what Google says you do not need, the snippet and indexing controls, and where the traffic shows up.
Google's documentation says AI Overviews and AI Mode surface relevant links to help people find information quickly. AI Overviews give a quick take on a topic with links to explore further. AI Mode suits queries that need more exploration, reasoning or comparison, and returns an AI-powered response with links to supporting sites.
Google says both features may use query fan-out, which means issuing multiple related searches. Google states this lets it display a wider and more diverse set of helpful links. It also says AI Overviews are only shown when its systems determine they are additive to classic Search, so they often do not appear.
To be shown as a supporting link, a page must be indexed and eligible to be shown in Google Search with a snippet. It must meet the Search technical requirements, and Google says there are no additional technical requirements. Google also notes that meeting the requirements does not guarantee crawling, indexing or serving.
Google does not say that being indexed and snippet eligible places a page in an AI response. Eligibility is a minimum, and the documentation makes no promise of inclusion or of a link position.
Google states there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary. It says you do not need to create new machine readable files, AI text files or markup to appear, and that there is no special schema.org structured data to add.
Google's separate AI optimization guide repeats and extends this. It says structured data is not required for generative AI search, there is no requirement to break content into tiny pieces, there is no ideal page length, and you do not need to write in a specific way for generative AI search. The guide still suggests keeping structured data as part of your overall SEO strategy.
Google points to the same controls it offers for classic Search results. The robots meta tag documentation says which of them reach the AI features.
| Control | What it does | AI features, per Google |
|---|---|---|
| robots.txt for Googlebot | Manages crawling access for Search | Google calls it the control for site owners to manage access |
| nosnippet | Do not show a text snippet or video preview | Applies to AI Overviews and AI Mode; prevents use as a direct input |
| max-snippet | Limits snippet length in characters; 0 acts like nosnippet | Limits how much content may be used as a direct input |
| data-nosnippet | Marks parts of an HTML page not to be used as a snippet | The robots meta tag page does not say whether it affects AI features |
| noindex | Do not show the page in search results | The robots meta tag page does not say whether it applies to AI features |
| Google-Extended | robots.txt token for Gemini training and grounding | A separate control for some other Google systems; not a Search ranking signal |
Google says sites appearing in AI Overviews and AI Mode are included in the overall search traffic in Search Console. That traffic appears in the Performance report under the Web search type. The documentation does not describe a separate filter for AI features, so you cannot isolate it from this guidance alone.
If content still appears after you add a preview control, Google says to verify the control with the URL Inspection tool and allow time for recrawling, which can take days to months.
Confirm your important pages are indexed and can show a snippet. Check that robots.txt does not block Googlebot and that no stray nosnippet or noindex rule applies. Use max-snippet or nosnippet only if you accept losing normal snippets too, because the same controls apply to classic results. Keep structured data accurate and consistent with visible text, but do not add markup just for AI features.
