Google Gemini answers factual and current questions by grounding with Google Search: it retrieves from Google’s index and cites the sources it used. So the foundation for appearing in Gemini is the same as SEO, being indexed, authoritative, and structured, with one Gemini-specific lever on top: Google-Extended. This guide explains how grounding works, what Google-Extended actually controls, and a step-by-step checklist you can run this week.
Gemini is one model on two surfaces#
The first thing to get straight is what “Gemini” means. Gemini is Google’s AI model, and it shows up in two different places: the Gemini app (the standalone assistant) and AI Overviews inside Google Search. Same model, different surfaces and different controls. Optimizing for one largely helps the other, because both ground in Google’s index, but as you will see, one control behaves differently between them.
How Gemini grounds an answer#
For a factual or current question, the Gemini app does not answer from memory alone. It grounds with Google Search: it issues a search, retrieves candidate pages from Google’s index, favors authoritative sources, and synthesizes an answer with citations to the pages it used. Its double-check feature can then validate individual statements against Search, highlighting what is corroborated.
The signals that get you grounded#
Because Gemini grounds in Google’s index and leans on Google’s quality signals, the signals that win a citation look like authoritative SEO aimed one layer deeper at the passage.
The Gemini checklist#
You can run this in an afternoon.
- Confirm indexation. Googlebot can crawl the page and it is indexed.
- Allow Google-Extended in robots.txt so Gemini can use your content.
- Answer first, with authority. A self-contained answer under each heading, backed by demonstrated expertise.
- Add schema and structure. FAQPage and Article, clean headings, lists.
- Earn corroboration. Get the claim confirmed across credible sources.
- Keep it fresh. Visible dates; refresh time-sensitive pages.
- Measure across engines. Track Gemini alongside ChatGPT, AI Overviews, Perplexity, and Claude.
Where measurement fits#
Gemini’s answers vary by query and grounding, so you cannot eyeball whether you appear. The reliable approach is to monitor a set of target questions on a schedule and record when Gemini cites you, across every engine, since Gemini, Google AI Overviews, ChatGPT, and Perplexity pull different sources for the same question. That cross-engine, honest measurement is what Prefer is built for. See the companion guides on how to appear in Google AI Overviews and how to get cited by Perplexity, or run a free AI visibility audit to see where you stand across all five surfaces today.
