FREQUENTLY ASKED
What is Google-Extended?
Google-Extended is a separate crawler from Googlebot used for AI training and Gemini products including Google AI Overviews. Blocking it affects Gemini citations but not your Google Search rankings.
Should I block Google-Extended?
Only if you explicitly don't want your content used for AI training. For most businesses, allowing Google-Extended means potential citation in Google AI Overviews — high-visibility placements above search results.
Is Google-Extended the same as Googlebot?
No. Googlebot powers traditional Google Search. Google-Extended powers Gemini and AI Overviews. You can block one without affecting the other using separate robots.txt rules.
