Free Robots.txt Checker
Test and validate your robots.txt file according to official RFC 9309 standards. Test specific paths against major crawlers and detect syntax errors instantly.
How to Use Free Robots.txt Checker
Enter your website domain or full robots.txt URL, specify an optional URL path to test (such as /blog/new-post or /checkout/), and select the search engine crawler you wish to validate (such as Googlebot, Bingbot, or wildcard *). Click 'Check Robots.txt' to fetch your live file. The tool parses directives using RFC 9309 standards, highlights whether the path is allowed or blocked, pinpoints the exact line number of matching rules, and validates all declared XML sitemaps.
Enter Domain
Type your website domain (e.g., example.com) to automatically locate robots.txt.
Define Test Path

Why Robots.txt Validation Matters
Your robots.txt file is the front door of your website for search engines. A single misplaced slash or poorly placed wildcard directive can accidentally instruct Google and other crawlers to ignore entire sections of your website or block critical CSS and JavaScript files needed for rendering. Conversely, an outdated robots.txt may leave staging directories or duplicate pages exposed to indexation, squandering crawl budget. Regularly testing your directives prevents catastrophic de-indexing accidents and ensures crawl budget is focused on revenue-generating pages.
