Robots.txt Validator FAQ
How does the robots.txt validator work?
Our validator parses your robots.txt file and checks it against the official robots.txt specification. It detects syntax errors, validates directives, checks for common mistakes, and provides security recommendations.
What errors does the validator detect?
The validator checks for: invalid directive names, missing colons, incorrect directive order, invalid user-agent values, malformed sitemap URLs, and more. It also warns about high crawl-delay values and security issues.
Can I validate robots.txt from any website?
Yes! Use the "Fetch from URL" button to automatically load and validate the robots.txt file from any publicly accessible website. Just enter the domain name and we'll retrieve it for you.
How do I validate my WordPress robots.txt?
WordPress automatically generates a robots.txt file, but you can customize it using plugins like Yoast SEO or All in One SEO. To validate your WordPress robots.txt, simply enter your site URL (e.g., yoursite.com) and click "Fetch from URL". Our validator will check for common WordPress-specific issues like blocking wp-content unnecessarily or missing sitemap references.
Can I validate my Shopify robots.txt?
Yes! Shopify generates a default robots.txt automatically. While you can't directly edit Shopify's robots.txt, you can validate it to ensure it's not blocking important pages. Use our validator to check if your Shopify store's robots.txt is allowing search engines to crawl product pages, collections, and blog posts. Note that Shopify automatically handles most robots.txt optimization, but validation helps identify any issues.
Is this robots.txt validator free?
Yes, completely free! No sign-up required, no limits on validations. Use it as many times as you need to ensure your robots.txt file is error-free.
What's the difference between warnings and errors?
Errors are critical issues that prevent your robots.txt from working correctly (like syntax mistakes). Warnings are recommendations or potential issues that won't break functionality but might impact SEO or security.
