Is Gemini the same as Google AI Overviews?

Google runs several AI products, and they share a brand more than they share rules. AI Overviews are summaries that Google Search shows for some queries. AI Mode is a conversational mode inside Search. The Gemini app is a standalone assistant. If you want the full map, see how many Google AI surfaces can show your brand.

The controls split along the same line:

What this means: a site can block Google-Extended and still be eligible for AI Overviews. A site that blocks Googlebot or sets nosnippet loses AI Overviews eligibility, whatever it does with Google-Extended.

Google's AI features documentation is direct. To be shown as a supporting link in AI Overviews or AI Mode, "a page must be indexed and eligible to be shown in Google Search with a snippet." Google adds: "There are no additional technical requirements."

Three things follow from that.

• No separate crawler. There is no robots.txt token that blocks AI Overviews alone. Googlebot rules are the control, as covered in AI Overviews and Googlebot.
• Snippet rules apply. 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.
• Search Console has an opt-out. Inclusion is the default, and child properties inherit the parent's setting. Google describes the control as rolling out to a subset of owners, so many sites see no toggle yet. Read more on Google's AI features control in Search Console.

Eligibility is not inclusion. Google says indexing and serving "isn't guaranteed," and AI Overviews often don't trigger at all.

Google-Extended is a robots.txt token. Per Google's common crawlers documentation (updated July 2026), disallowing it cuts your content from training and grounding for Gemini Apps and Vertex AI. The same page says it "does not impact a site's inclusion in Google Search nor is it used as a ranking signal."

A site-wide block looks like this:

User-agent: Google-Extended
Disallow: /

Blocking it removes a grounding source for the Gemini app. It does not touch AI Overviews, which this answer on Google-Extended and AI Overviews covers in detail. Nobody has measured whether allowing it makes Gemini name a brand more often. Decide based on whether you want Gemini Apps to use your pages, not on a promised visibility gain.

The confusion has real causes. Here are the edge cases worth knowing as of October 2026.

• Gemini is also a model family. Google's I/O post named gemini-3.5-flash as AI Mode's default from May 2026. Secondary reports say AI Overviews run on the Gemini 3 family, and Google publishes no exact version. So AI Overviews can use a Gemini model while remaining a separate product.
• AI Overviews and AI Mode differ too. Google says they "may use different models and techniques" and can return different links for the same query.
• The Gemini API is another path. Developers can call Grounding with Google Search directly. An app built on it is neither the Gemini app nor AI Overviews. See how Gemini grounds answers.
• Retrieval is per query. The Gemini app may answer from what the model already knows, without searching. A missing mention on one query is a data point, not a verdict.

Work through the controls you own first, then measure.

1. Confirm Googlebot can crawl your key pages and that Search Console shows them indexed.
2. Scan templates for noindex, nosnippet, max-snippet and data-nosnippet, and remove any you didn't intend.
3. Check the Search Console AI features control, including any setting a child property inherits from its parent.
4. Set Google-Extended deliberately, and write down why.
5. Track AI Overviews, AI Mode and the Gemini app as three columns. Search Console's generative AI report shows impressions only, for AI Overviews and AI Mode. Learn what Search Console reports for Gemini.
