AI crawler guide

AI Crawler User Agents List

Reference list of AI crawler robots.txt tokens, companies, purposes, and practical allow/block defaults.

Search intent

Users want to know which bot names to put in robots.txt and what each one does.

Practical checklist

  • Crawler names change, so each token should link back to a vendor or maintained list.
  • Some controls are robots.txt tokens rather than strings you will see in logs.
  • Use company-specific pages when you need more detailed tradeoffs.
