The Google-Extended setting controls whether your content is used for Gemini training and grounding. It does not affect Google Search or AI Mode.
There is no Gemini-only trick: an indexed, crawlable site with clear facts and outside proof is what gets cited.

What is Gemini SEO?

Gemini SEO is the work of getting your business found, understood and cited when people ask the Gemini app a question. It is part of GEO, generative engine optimization. Because Gemini grounds its answers on the Google Search index, Gemini SEO starts with classic SEO and adds clear, quotable facts and proof from other sites.

People use "Gemini SEO" for three different things, and the advice changes with each. So before any tactic, it helps to know which Gemini you are talking about. If you want the bigger picture first, the GEO hub explains how all AI engines pick sources.

Product	What it is	Where it gets web content	What controls it
Gemini app	Google's AI assistant (web and mobile)	Grounding with the Google Search index	Google-Extended, plus normal indexing
AI Overviews	AI summary on top of Google results	Google Search index	Normal indexing and snippet controls
AI Mode	Conversational search tab in Google	Google Search, with query fan-out	Normal indexing and snippet controls

AI Mode has its own guide: Google AI Mode SEO. This page is about the Gemini app.

Where does Gemini get its information?

From two places. The model learned from web text during training, and when a question needs fresh or specific facts, Gemini grounds its answer with content from the Google Search index. Google calls this giving the model content from that index at prompt time. If Google has not indexed you, Gemini cannot ground on you.

That definition comes straight from Google's crawler documentation, and it is the most useful sentence for anyone doing Gemini SEO. It means there is no separate "Geminibot" to invite and no separate index to submit to. Your pages need to be in Google's index, readable without a login and clear enough to be quoted.

Gemini does not always show where an answer came from. Google's Gemini Apps Help says that sometimes the app shows sources within and below a response, and that if it quotes a large amount of text from a webpage, a link to that page appears in the sources list. If there is no Sources button, the app did not provide links for that answer. In practice, this means being named matters as much as being linked: many Gemini answers mention a business by name with no link at all.

Should you block Google-Extended?

Usually not, if you want Gemini to recommend you. Google-Extended is a robots.txt token that controls whether Google may use your content to train Gemini models and to ground answers in the Gemini app. Blocking it does not remove you from Google Search, but it can keep your pages out of the facts Gemini uses when it answers.

Google is explicit that Google-Extended does not impact a site's inclusion in Google Search and is not a ranking signal there. AI Overviews and AI Mode are part of Search, so they are not controlled by this token. The trade-off is simple: a news publisher protecting its articles may block it; a dentist, a store or a consultant who wants to be recommended normally leaves it open. Check your robots.txt: some security plugins and "block AI" toggles add a Google-Extended disallow without telling you.

Gemini SEO in 6 steps

This is the order I use, from the fastest fix to the slowest:

Confirm you are indexed. Use Search Console's URL Inspection on your home page and main service or product pages. Gemini grounds on the Search index, so unindexed pages do not exist for it.
Check robots.txt for Google-Extended and Googlebot. Remove accidental blocks. Keep important text in the HTML, not only inside images or late JavaScript.
Write the answer in the first lines. Say what you do, for whom, where and at what price. That is the sentence Gemini can repeat.
Add facts with sources. The original GEO study found that citing sources, adding quotations and adding statistics raised visibility in AI answers by about 30 to 40%.
Make your business data identical everywhere. Same name, address, phone, services and hours on your site and your Google Business Profile. Gemini mixes what it finds; contradictions lower trust.
Earn proof on other sites. Reviews, directories, local press and industry lists. Do not fake it: Google warns that seeking inauthentic mentions is not as helpful as it seems.

Notice what is missing. Google's guide to generative AI features says you do not need new machine-readable files, AI text files or special schema.org markup, and you do not need to break your content into tiny pieces. Those statements are about Google Search, but since Gemini grounds on the same index, they are the best official guidance we have. My GEO audit checks all six steps and runs your buyers' questions in Gemini.

Does Gemini SEO work for Spanish and local searches?

Yes, and that is where many businesses have an easy opening. Gemini answers in Spanish and often names local businesses, but most GEO advice is written for US brands in English. If your pages, Business Profile and reviews are complete in Spanish, you compete against far fewer prepared rivals. Test your questions in both languages.

In my audits I run every question in English and Spanish, because an AI often finds different sources in each language. For a business in Medellín, Bogotá or Miami, the Spanish answer is frequently thinner and easier to win. If you sell to both markets, write each language for its reader instead of translating word for word, and keep the same facts (prices, hours, address) in both.

How do you measure Gemini visibility?

With a fixed test and one official report. Ask Gemini the same 15 to 25 buyer questions every month, logged out and in both languages, and record who is named and which links appear. GA4 groups chatbot visits, including Gemini, in its AI Assistant channel. Google does not offer a Gemini app report in Search Console.

GA4's AI Assistant channel counts visits that arrive from assistants like ChatGPT, Gemini and Copilot. Search Console's generative AI performance report, rolled out to all sites on August 31, 2026, covers AI Overviews and AI Mode, not the Gemini app. So your monthly test is the main source of truth. Look for a trend over three months, not a single answer, because AI answers change between runs. When you are ready, compare the monthly GEO plans, or go back to the home page to see how I work.

Frequently asked questions

Does Gemini use Google Search?

Yes. Google says the Gemini app can ground its answers with content from the Google Search index at prompt time, to improve factuality and relevancy.

Is there a Gemini crawler I need to allow?

No separate one. Gemini relies on what Googlebot indexed. The Google-Extended token only controls whether that content may be used for Gemini training and grounding.

Why does Gemini mention my competitor and not me?

Usually because the competitor has clearer facts on its pages, more consistent business data or more mentions on other sites. Check that you are indexed and compare what each site says.

Do I need llms.txt or special schema for Gemini?

No. Google's guide says you do not need AI text files or special schema.org markup for its AI features. Accurate structured data that matches the page still helps search in general.

How long does Gemini SEO take?

Indexing and crawl fixes can show within weeks. Mentions on other sites and stronger reputation take months. Measure the trend over at least three monthly tests.
