How to get cited by Google Gemini
Gemini cites the web when it grounds answers in Google Search, which means Gemini visibility is Search visibility plus citability. There is no separate Gemini index and no Gemini submission form. The 1 Gemini-specific control, Google-Extended, is documented by Google as an opt-out from Gemini training and grounding that “does not impact a site's inclusion in Google Search nor is it used as a ranking signal in Google Search” (Google crawler docs). So the work is 4 layers: be indexed, be readable, be liftable, be unambiguous.
Understand the one Gemini-specific switch
Google-Extended is a robots.txt token, not a crawler you will see in logs. Disallowing it tells Google not to use your content for training future Gemini models or for grounding Gemini answers. It does not remove you from Search, and per the documentation it is not a Search ranking signal in either direction. But the grounding half matters: because grounding is inside Google-Extended's documented scope, blocking it can keep your pages out of grounded Gemini citations even while your Search rankings stay untouched. Background in our Google-Extended glossary entry. If you want Gemini citations, leave it allowed.
Layer 1: Search eligibility, the boring foundation
Grounded Gemini answers draw on Google Search. If a page is not indexed, or your site ranks nowhere for the topic, there is nothing for Gemini to find. Confirm indexation in Search Console, fix any accidental noindex, and get honest about whether you have any ranking presence in the topic you want cited for. AI answers are downstream of the index. Everything downstream inherits problems from here.
Layer 2: readable without JavaScript
Machines reading your pages at scale read HTML. If your content only exists after scripts execute, you are invisible to every reader that does not run them. View source, search for your own key sentence, and if it is absent, start at the JavaScript rendering fix. This single failure suppresses Search ranking and AI citation together, which is why it sits near the top of our audit's severity order.
Layer 3: liftable passages
A model assembling an answer needs a passage it can extract and attribute: self-contained, specific, factual. Pages that open with the answer, state numbers, and cite sources give the model a safe quote. Pages that are all narrative give it nothing. Restructure your money pages using answer blocks and passage extractability. This is the same work that targets AI Overviews, and it compounds: one restructure serves both surfaces.
Layer 4: an unambiguous entity
Attribution requires certainty about who you are. Publish complete Organization schema, keep your name and details consistent everywhere machines look, and connect your profiles with sameAs links. The details are in fixing entity clarity. An engine that cannot resolve your identity cites a competitor it can resolve.
What we do not know, stated plainly
Google does not publish Gemini's citation selection criteria, and anyone reciting a precise recipe is guessing with confidence. What is documented: grounding uses Search, training controls are separate, and content standards are the same people-first guidance as everywhere else in Google's ecosystem. Optimize the documented layers, then measure referral traffic from gemini.google.com in your analytics rather than interrogating the model about itself.
Frequently asked questions
Is Gemini optimization different from ChatGPT optimization?
The site-side work overlaps almost completely. The difference is the index behind the engine: Gemini grounds in Google, ChatGPT search leans on Bing among other sources. Cover both indexes and the rest of the checklist is shared. See the ChatGPT diagnostic.
Should I block Google-Extended?
Understand what you are trading first. Blocking it does not change your Search rankings, but per the documentation it withdraws your content from Gemini training and grounding, which can remove your Gemini citations. If AI visibility is the goal, that is a real cost.
