Why Gemini Matters for SEO Managers
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. For an SEO manager, that is the part of Gemini you already know how to work: crawl access, indexation and clear page structure feed what it can use. The difference is the output: instead of ranking ten links, Gemini writes an answer from content Googlebot crawls, subject to your Google-Extended setting for Gemini grounding.
The Gemini Mistake to Avoid
Treating Google-Extended as a crawler. It is a robots.txt token with no user agent of its own: disallowing it opts content out of Gemini training and grounding, while a Googlebot block removes pages from Google Search and Gemini alike.
