What it is definition
Crawls and renders pages for Google Search, Images, Video, News and Discover.
Googlebot is operated by Google and classified here as answer index. These agents build the index an answer engine queries at question time. Disallowing one removes the site from those answers and from the citations that link back to it. Training is governed by separate tokens, so this is the expensive block, not the protective one.
Disallowing googlebot removes the site from the index Google Search queries when it answers a question. The engine can then neither quote nor link the page, which is a traffic decision rather than a licensing one. Model training is governed by separate tokens.

Common questions answered
Does blocking Googlebot remove me from Google Search?
Yes, in effect. Googlebot builds the index Google Search reads at question time, so disallowing it takes the site out of those answers and out of the citations that link back to it. This is the block that costs traffic.
How do I verify Googlebot requests are genuine?
Run a reverse DNS lookup on the source address. It must resolve to a host under googlebot.com or google.com, and a forward lookup of that host must return the same address. Google also publishes its crawler ranges as JSON, so an address match works when reverse DNS is unavailable.
