What an AI training crawler does
A training crawler gathers public pages that may end up in the data used to train AI models. It sends no visitors back, so blocking it is the usual choice for sites that don't want their content used that way.
Common Crawl warns that other bots pretend to be CCBot, so check the IP.
Block or allow CCBot in robots.txt
Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.
