Google-Extended— definition

With this, you appear in Google search results while not being cited by Gemini.

That said, the GEO recommendation is Allow both as the default (otherwise you forfeit citation opportunities from AI search).

Why is it important?

• Google AI Overview appears at the top of search results: big impact on CTR
• Gemini is seeing growing enterprise adoption
• A new identifier introduced from 2024 onward: many companies still miss configuring it

Configuration (GEO recommendation)

Or, leaving nothing in robots.txt (default Allow) is fine.

Common misconceptions

• "Allowing Googlebot also reaches the AI" -> wrong. Google-Extended is a separate axis
• "Disallowing Google-Extended has no impact on Google Search" -> correct
• "Disallow completely prevents AI training" -> half-correct (only for Google)

See robots.txt and Gemini for details.
