robots.txt checker for AI
Check any site's robots.txt, or paste your own. We flag mistakes, show which AI crawlers are blocked, and write a corrected file.
How do AI crawlers read robots.txt?
Each crawler uses the group that names it; if none does, it uses the * group. Within a group the longest matching rule wins, and Allow wins a tie.
Will opening up to AI hurt my SEO?
No. Allowing AI search crawlers does not affect Google rankings. Blocking Google-Extended or GPTBot only stops model training, not search.
Where does robots.txt go?
At the root of your domain, for example example.com/robots.txt. Each subdomain needs its own.
Is robots.txt enough?
It is a request, not a lock. Check your firewall too with the AI crawler checker.
