Google — User-initiated

All crawlers · Agent Accessibility Index

Purpose: User-initiated. Fetches a specific page because a user asked, rather than crawling broadly. Blocking this stops people using an assistant to read the site; it does not prevent training.

Fetches pages while Gemini carries out a multi-step research task for a user.
