Test Robots.txtFrequently Asked Questions
Is this robots.txt tester free?
Yes. You can test any public domain and receive a free robots.txt report with crawl rule analysis and recommendations.
Can robots.txt block my entire site from search?
Yes. A rule such as Disallow: / for a broad user-agent group will effectively block crawling for that segment. The tester highlights these patterns so you can avoid accidental lockouts.
Does this tool modify my robots.txt file?
No. The tester performs a read-only HTTP request to /robots.txt, parses the response and presents the rules in a human-friendly format.
How often should I review robots.txt?
Review your robots.txt whenever you launch a new section, migrate a site, change CMS routing or update your AI crawler policy.
Why do AI crawler rules matter?
As AI crawlers become more common, robots.txt acts as the public contract for your AI bot policies—stating which agents may access your content and which should stay away.
