Gemini: Make Your Documentation Discoverable by AI
AI Can't Find Your Documentation on Gemini? Here's why it happens, the fix, and how to prevent it.
Gemini Context
Position your brand to be recommended by Google's Gemini AI across Search, Workspace, and Google's ecosystem.
Leave the Google-Extended robots.txt token allowed if you want Gemini to use your content for grounding (it does not affect Google Search)
Maintain strong traditional SEO fundamentals
Implement comprehensive structured data markup
Why This Problem Matters
Users ask AI for help with your product but it can't find or cite your documentation. Get your docs into AI knowledge.
Why This Happens in Gemini
Documentation is only usable if Gemini can reach it through content Googlebot crawls, subject to your Google-Extended setting for Gemini grounding. Docs behind a login, on a blocked subdomain, or rendered client-side are invisible however good they are.

Gemini Technical Details
Gemini has no separate crawler: Googlebot does the crawling, and the Google-Extended robots.txt token (not a separate user agent) controls whether that content is used for Gemini training and grounding without affecting Google Search. Pages a user hands to Gemini are fetched by Google's user-triggered fetchers, which generally ignore robots.txt.
Googlebot
Search / answers
Crawls for Google Search; its fetches also supply Gemini.
Google-Extended
