ADVERT
robots.txt Auditor
Paste your robots.txt file to inspect syntax errors, visualize user-agent coverage, and test whether URLs are blocked or allowed.
How to use this tool
- Paste your `robots.txt` file into the source input.
- Review parser issues, user-agent rule groups, and sitemap entries.
- Simulate URL access per user-agent to verify allow/disallow behavior.
Audit coverage
- Highlights malformed directives and missing user-agent context.
- Groups allow/disallow rules by crawler for quick inspection.
- Surfaces crawl-delay and host directives when present.
Validation tips
- Keep groups separated and avoid directive typos for predictable crawler behavior.
- Check high-value URLs against multiple agents before deployment.
- Ensure sitemap URLs are absolute and publicly reachable.
FAQ
- Does this validate unknown directives?
- Yes. Unrecognized directives are flagged so you can correct potential syntax issues.
- Can I test specific crawler behavior?
- Yes. Use the URL simulator with a user-agent value to see allow/block outcomes.
- Does this replace search engine testing tools?
- No. It helps catch structure and rule conflicts quickly, but live crawler tools are still recommended.
