Google-Extended blocked — should you allow it?

If Google-Extended is blocked in your robots.txt, Google's generative AI crawler may not fetch your pages for Gemini-related use cases, whilst Googlebot can still crawl for classic Search indexing. Whether you should allow Google-Extended depends on legal policy, content licensing, and appetite for Google's generative AI systems to read public pages — not on a guarantee of more AI Overviews or citations. Allowing Google-Extended does not force inclusion; blocking it does not automatically protect all training uses if other crawlers or channels apply.

Document the decision for your team: allow both Googlebot and Google-Extended, block only Google-Extended, or seek counsel for regulated industries. Re-fetch live robots.txt after CMS updates because plugins often reintroduce blanket AI disallows.
