How Gemini chooses its sources, what Google-Extended really controls, and the steps to get your brand and pages cited in Gemini, AI Overviews and AI Mode.

In short
Gemini answers with the knowledge of its model and, for most factual or commercial questions, with results from Google Search that it uses to ground its answer and cite sources. To rank in Gemini, first rank well on Google for the questions behind your prompts, write passages that answer one question clearly, keep your brand facts consistent across the web, earn mentions on the sources Google trusts, and allow Google-Extended if you want your content to be used for grounding in the Gemini app.

Gemini is Google's AI assistant, available as an app, inside Android and Chrome, and in Workspace. Its answers draw on the same index as Google Search, which makes ranking in Gemini closer to classic SEO than ranking in other assistants. Google explains how it controls AI uses of your content in its documentation on Google crawlers, including the Google-Extended token.
Gemini combines two layers. The model itself holds general knowledge learned during training. For questions that need current or precise information, Gemini runs searches in Google's index, reads the results and grounds its answer in them, often showing the pages it used. Google's own AI features in Search, AI Overviews and AI Mode, work in a similar way and also break a question into several sub queries before choosing passages.
The practical consequence: a page that Google does not index or ranks poorly for the underlying queries has little chance of being used. A page that ranks and contains a clear, self-contained answer to a sub question has a real chance, even if it is not in first position.
| Setting | Effect |
|---|---|
| Blocking Googlebot | Removes your pages from Google Search, and therefore from AI Overviews and AI Mode |
| Blocking Google-Extended | Your content is not used to train future Gemini models or to ground answers in the Gemini app and Vertex AI; it does not affect Google Search ranking or AI Overviews |
| Allowing both | Your content can appear in Search, in Google's AI features and in Gemini answers |
If being cited in Gemini matters to you, do not block Google-Extended in robots.txt. Check with your CMS or CDN that no default rule blocks it. See our glossary entry on Gemini for background.
List the prompts your customers type in Gemini, then the Google queries they imply: "best [category] for [use]", "[brand] reviews", "[product] price", "how to [task]". Work your SEO on those queries first: indexing, intent, content depth, internal links, authority.
Gemini and AI Overviews extract passages, not whole pages. Put a direct answer of two or three sentences under each question heading, define terms, state numbers with their source, and use tables for comparisons. Each section should make sense if read alone.
Google connects your brand to an entity in its Knowledge Graph. Keep the same name, description, address and offer on your site, your Google Business Profile, social profiles and directories. Add Organization and, where relevant, Product, LocalBusiness or Person structured data.
Reviews, comparison articles, industry media, YouTube videos and forum discussions shape how Gemini describes your brand. Being mentioned for the same use case by several independent sources is what turns a brand into a recommendation.
Gemini avoids sources that look outdated or contradictory. Update prices, features and dates, and remove pages that no longer reflect your offer.
| Surface | Where it appears | What drives citations |
|---|---|---|
| AI Overviews | Above Google results for some queries | Google index and ranking, clear passages |
| AI Mode | A dedicated conversational tab in Google Search | Many sub queries, passages from varied sources |
| Gemini app | Standalone assistant, Android, Chrome, Workspace | Model knowledge plus grounding in Google Search; Google-Extended applies |

Answers vary with the wording and the user, so a single test proves nothing. Track a fixed set of 20 to 50 prompts over time and note whether your brand is mentioned, how it is described, and which competitors and pages are cited. Our free Gemini ranking tool gives a first snapshot.
Ranking in Gemini starts with ranking on Google, then with passages clear enough to be quoted and a brand that independent sources describe the same way. Sorank tracks your visibility in Gemini, alongside ChatGPT and Claude, and publishes the articles that close the gaps on autopilot, with a 3-day free trial.
No. Google states that Google-Extended does not affect inclusion or ranking in Google Search. It only controls whether your content can be used to train Gemini models and to ground answers in the Gemini app and Vertex AI. AI Overviews and AI Mode depend on Googlebot and on Search indexing.
They are related but not identical. Both rely on Google's index, so good SEO helps both. AI Overviews appear inside Google Search results, while the Gemini app is a standalone assistant that also uses its model's knowledge and is subject to the Google-Extended setting.
If your pages already rank on Google for the relevant queries, improving passages and structured data can show effects within weeks. Building the authority and third-party mentions that make Gemini recommend a brand usually takes two to four months of steady work, sometimes more.
