Google-Extended

A robots.txt control token only: Google crawls with its usual crawlers, so no request is ever Google-Extended. It controls Gemini training and grounding, not Search or AI Overviews.

If you block it

Tells Google not to use your pages for this purpose. It is a control token, so crawling by its other bots carries on.

Check a visit is real

Nothing to check: no request ever carries this name. It only appears in robots.txt.
