Googlebot

Google's main search crawler; controls Google Search, including AI features built on the Search index. Almost never block.

Should you block it?

Almost never block

Googlebot builds the Google Search index, and Google states that crawl preferences addressed to it affect Google Search — including AI features built on the Search index. Blocking it removes you from normal Search results as well as those AI surfaces.

If you want to control snippet or AI usage without leaving Search, use nosnippet or noindex at page level instead.
