What it is

The classic search crawler. It is also the crawler behind AI Overviews: Google does not run a separate bot for them, which is why the only AI opt-out is the Google-Extended token and not a Googlebot block.

What blocking it costs you

Total. You leave Google Search. Never block this to avoid AI use; use Google-Extended instead.
