Does blocking Google-Extended remove my site from AI Overviews?

No. AI Overviews and AI Mode are built on the regular Search index created by Googlebot, so Google-Extended has no effect on them. To limit appearance there, use existing Search controls like nosnippet or noindex.

Is Google-Extended a separate crawler bot?

No. Google-Extended has no user agent string of its own. Crawling is done by existing Google crawlers; the token only controls whether that content may be used for Gemini training and grounding.

Does blocking Google-Extended hurt my Google Search visibility?

No. Google-Extended is a robots.txt token that only opts your content out of Gemini model training and grounding — Google's official documentation states it does not affect a site's inclusion in Google Search and is not used as a ranking signal. Search crawling is handled separately by Googlebot, and AI Overviews are built on the regular Search index, not on Google-Extended.
