AI Crawlers

AI crawlers are bots such as GPTBot and PerplexityBot that fetch web content for AI training and retrieval; allowing them is a prerequisite to being cited.

AI crawlers are automated bots — such as GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, and Google-Extended — that fetch web content for AI training and real-time retrieval. Site owners control their access through robots.txt directives.

Allowing reputable AI crawlers is a prerequisite to being cited: a page that is blocked cannot be retrieved or referenced in an answer. Blocking them protects content from training but also removes it from AI answer visibility.

Frequently asked questions

Should I allow AI crawlers?
If AI visibility is a goal, yes — a blocked page cannot be cited. Some publishers block them to protect content from training, which is a trade-off between control and visibility in AI answers.
