Documentation
Open source documentationWhat is Google-Extended?
Google fetches pages with existing Google user agents. Google-Extended then controls whether Google-crawled content may be used for the documented Gemini purposes.
Purpose and SEO meaning
The KI-Console group is training, more precisely a control token for training and grounding. Google says Google-Extended does not control Google Search inclusion and is not a Search ranking signal.
Visibility and privacy note
Blocking Google-Extended can reduce how systems from Google see, index, train on, or retrieve your public content. Allowing it improves technical access, but it never guarantees crawling, ranking, citation, or a positive AI answer.
Use the exact Google-Extended token in robots.txt. Blocking it reduces eligibility for the listed Gemini uses, but it does not block Googlebot.
