How to get cited by Gemini: same company, different rules

Three products, one name

Most confusion about "getting cited by Gemini" comes from treating it as a single target. It is not. The Gemini app is a standalone chatbot, competing directly with ChatGPT and Claude. The Gemini API, used by developers, can be "grounded" with live Google Search results at the moment a query runs. AI Overviews are a different surface entirely: a panel inside regular Google Search results, now built on Gemini models but governed by Search's own ranking logic first. This guide is about the first two. Optimizing for Google AI Mode and how Google picks AI Overview sources already cover the third, and treating all three as the same problem is how a site ends up optimizing for the wrong one.

One crawler token, two jobs

Google runs Googlebot for Search indexing and a separate token, Google-Extended, for Gemini. Google's own crawler documentation, last updated 14 July 2026, states plainly that Google-Extended controls whether content can be used both for "training future generations of Gemini models" and for grounding, meaning Grounding with Google Search inside Gemini Apps and the Vertex AI API. Blocking Google-Extended in robots.txt opts a site out of both at once. It does not touch Search ranking. That same page states outright that Google-Extended "does not impact a site's inclusion in Google Search nor is it used as a ranking signal in Google Search." That matches what Google first said when it introduced the token on 28 September 2023 and later clarified was unchanged, per Google's own crawling changelog. The practical read: a site that blocked Google-Extended years ago to opt out of AI training may have quietly opted out of live Gemini citations too, without anyone deciding that on purpose. Confirming your own robots.txt against the current token list, alongside the other AI crawlers, is covered in the AI crawlers guide.

The ranking correlation nobody expects

Ahrefs analyzed 15,000 long-tail queries across AI engines and published the results on 11 August 2025. Google AI Overviews cited a page already ranking in the top 10 for the same query about 76% of the time, which tracks with Google's own description of Overviews as built on top of Search. Perplexity showed the next-closest alignment, 28.6%. Gemini and ChatGPT were nearly identical to each other and far lower than either, around 8%. A page that dominates page one of Google can be completely absent from a Gemini answer to a related question, and the study's own framing captures why: AI Overviews function like an extension of traditional search, while standalone assistants, Gemini included, do not, even when the assistant is built by the same company running the search engine.

What the API actually returns

Google's Gemini API documentation describes grounding with Google Search as a five-step process: the model decides whether a search would help, runs one or more queries, retrieves and synthesizes the results, then returns a response with inline citations. Cited text comes back as annotations attached to specific spans of the answer, each naming a source URL and the exact start and end of the text it supports, not a single source list bolted onto the bottom. The documentation does not publish how it chooses which retrieved pages earn a citation. That omission is the same one every other engine makes, and treating any third-party list of "Gemini ranking factors" as more than an educated guess is the same discipline this site recommends for Perplexity and ChatGPT.

What a person actually sees in the app

Google's own Gemini Apps help documentation describes a "Sources" panel that appears on some, not all, responses. The clearest trigger it names is a direct quote: if Gemini's answer lifts a substantial chunk of text from a page, that page shows up as a source link. Images pulled from the web and connected Workspace documents get the same treatment. The documentation says plainly that plenty of responses carry no visible sources at all. That means the absence of a citation on any single answer proves little. The only way to know your real citation rate is to run the same buyer questions repeatedly and count, which is exactly what measuring AI visibility walks through instrument by instrument.

What this means for your site

Decide about Google-Extended on purpose rather than by inherited default. If being cited inside Gemini matters to your business, confirm the token is allowed; if you blocked every AI crawler in 2023 out of blanket caution, you may have switched this off without meaning to. Write the sentence you want quoted as a single, complete, checkable claim, because citation attaches to a text span, not a page. And stop treating a page-one Google ranking as proof of Gemini coverage: the two systems agree often enough to be confusing and disagree often enough that only 8% of the time is real. The gap between what you rank for and what Gemini actually names you for is precisely the citation-gap analysis behind the AEO Visibility Audit.

A two-week check

Week one: pull your robots.txt and confirm whether Google-Extended is allowed or blocked, then check your server logs for its requests the way you would for any other crawler. Ask Gemini your five most valuable buyer questions directly in the app and note whether a Sources panel appears and what it names. Week two: take the one page you most want cited, tighten its core claim into one quotable sentence with a number attached, and re-ask the same five questions. The 8% figure means most pages will not move on the first try. That is the honest baseline, not a reason to skip the test.

Sources

Google's crawler documentation names what Google-Extended controls: see Google's common crawlers reference, updated 14 July 2026. The citation-overlap figures come from Ahrefs' analysis of 15,000 long-tail queries across AI engines, published 11 August 2025. The grounding mechanics come from Google's Gemini API documentation on grounding with Google Search, and the consumer-facing behaviour from Google's Gemini Apps help article on sources and related content.
