How many Google AI surfaces can show my brand?

Google doesn't have one AI product that cites websites. It has several, and each one reaches your content through a different path.

The reasoning is simple. Google's AI features documentation says a page must be "indexed and eligible to be shown in Google Search with a snippet" to appear as a supporting link in AI Overviews or AI Mode, and that there are no additional technical requirements. The Gemini app sits outside that rule. Google's common crawlers page says Google-Extended cuts training and grounding for Gemini Apps and Vertex AI, and that it "does not impact a site's inclusion in Google Search nor is it used as a ranking signal." So a site can be fully visible in AI Overviews and absent from Gemini, or the reverse. If you're unsure how those two relate, see whether Gemini is the same as AI Overviews.

These are the levers that sit in your hands. All of them work by removing a block, not by adding a boost.

For AI Overviews and AI Mode

• Googlebot in robots.txt. There is no robots.txt token that blocks AI Overviews or AI Mode on their own. Google says robots.txt directives for Googlebot are the control, because AI is built into Search.
• Robots meta and snippet rules. noindex, nosnippet, max-snippet:0 and data-nosnippet keep content out of AI answers. Templates often carry these by accident, for example on a block meant to hide a cookie banner.
• The Search Console inclusion control. Inclusion is opt-out and is "the default control for all properties." It covers AI Overviews, AI Mode and Discover's generative features. Child properties inherit from the parent, so a site can be excluded without anyone touching it. Read whether a Search Console setting could be hiding your site before you debug anything else.

For the Gemini app

• Google-Extended. Disallowing it removes your content from Gemini Apps training and grounding. Our digest of Google's common crawlers doc and Google-Extended covers the exact wording.

One thing Googlebot does that most AI crawlers don't: it renders JavaScript. Client-side rendering is a real risk for ChatGPT or Claude crawlers, but it isn't the usual cause of a Google AI gap.

A single number for "Google AI" averages things that don't belong together.

• Different models. Google's AI features page says AI Overviews and AI Mode "may use different models and techniques." As of October 2026, Google states AI Mode's default model changed on 2026-05-19, while it describes AI Overviews only as the Gemini 3 family. Our page on which models power AI Mode and AI Overviews tracks this.
• Different queries. AI Mode may use query fan-out, running several related searches across subtopics. Gemini API grounding generates its own search queries. Your test prompt isn't the query Google ran.
• Different triggers. AI Overviews often don't appear at all for a given search.
• Different gates. A Google-Extended block hurts Gemini and leaves AI Overviews untouched. An inherited Search Console opt-out does the opposite.

If one surface scores zero and another scores well, the blended score lands in the middle and points you at nothing. The fix depends on which gate is closed, so the measurement has to be per surface. The AI Overviews vs AI Mode comparison shows how far two Google surfaces can diverge.

Index status carries straight through to Google's AI surfaces. In OtterlyAI's published 2026 experiment, Google deindexed two AI-generated sites, and Google AI Overviews, AI Mode and Gemini almost never cited them afterward. Bing kept the sites, and Microsoft Copilot kept citing them. That is one pair of sites, but it matches Google's written eligibility rule.

Measurement is thin. Search Console's generative AI report shows impressions for AI Overviews and AI Mode, with no clicks, no CTR and no position. A Google-side bug depressed impressions in that report from around 2026-08-12, so treat trends from that window with care. Our Search Console generative AI report playbook explains what it can and can't tell you.

Opting out has limits too. Google says excluding content from AI features doesn't stop it being used to power Search as a whole, such as understanding the language of queries. And no setting guarantees inclusion: Google states indexing and serving aren't guaranteed.

1. Confirm Google indexing. Check that your key pages are indexed and carry no noindex or snippet restrictions you didn't intend.
2. Check the Search Console inclusion control on every property, including parents that children inherit from.
3. Read your robots.txt for Google-Extended. Decide on purpose whether Gemini Apps may use your content.
4. Measure each surface on its own. Run the same buyer questions in AI Overviews, AI Mode and Gemini, and record which cite you. The free checker on this site gives a quick snapshot for three buyer questions.
5. Fix wrong facts at the source. State prices, numbers and one-line definitions plainly on fetchable pages, so an engine that retrieves you has a sentence it can quote.

None of this promises a citation. It removes the blocks that are yours to remove.

Does blocking Google-Extended remove me from AI Overviews? No. Google's common crawlers documentation says Google-Extended controls training and grounding for Gemini Apps and Vertex AI, and that it does not affect inclusion in Google Search or act as a ranking signal. AI Overviews and AI Mode follow Search eligibility instead. To limit display there, use snippet controls such as nosnippet or data-nosnippet, or the Search Console generative AI inclusion control where your property has it.

Do I need special markup or an llms.txt to appear in AI Overviews or AI Mode? No. Google says there are no additional requirements or special optimizations for AI Overviews or AI Mode beyond being indexed and snippet-eligible. Its optimization guide says Google Search ignores AI text files such as llms.txt. Structured data isn't required for generative AI search either. Existing markup does no harm, but it isn't a lever for appearing in these answers.

Is the Gemini API the same as the Gemini app? No. The Gemini app is Google's consumer assistant, governed by Google-Extended. The Gemini API is what developers call from their own products, and Grounding with Google Search is a feature they switch on and pay for separately. When grounding runs, the model writes its own search queries. A test against the API is a proxy for the app, not a measurement of it, and neither stands in for AI Overviews.

Can Search Console tell me which Google AI surface showed my brand? Partly. As of October 2026, Search Console's generative AI report shows impressions for AI Overviews and AI Mode, broken down by pages, countries, dates and devices. It shows no clicks, CTR or position, and it doesn't cover the Gemini app. To see what each surface actually says about your brand, you have to run the questions yourself and record the answers surface by surface.

Why does my brand appear in AI Overviews but not in AI Mode? They are separate surfaces. Google says they may use different models and techniques and return different links, and AI Mode may fan a question out into several related searches. Your page can be eligible for both and still be picked for only one. Check eligibility first, then compare answers to the same question on each surface before changing any content.
