Run the Audit
The validator parses every directive and runs semantic checks — full-site blocks, duplicate groups, missing sitemaps, directives without a User-agent, and syntax errors on every line.
3
Test Bot Access
Use the Bot Access Tester to confirm whether a specific crawler (Googlebot, GPTBot, AhrefsBot, etc.) is allowed or blocked from any URL path before you deploy your changes.
