Robots.txt Checker and Crawl Directive Validator

Our free robots.txt checker lets you quickly verify if a website has a valid robots.txt file, read its raw directives, check user-agent rules, and confirm if XML sitemap declarations are correctly listed. This tool runs in real-time, fetching data directly from the target domain's root server.

Why is the robots.txt file critical for SEO?

A robots.txt file resides in the root directory of a website and acts as an advisory instruction guide for search engine bots (like Googlebot, Bingbot, and DuckDuckGo). It tells the bots which sections of your site they should crawl and which sections they should ignore. A properly configured robots.txt file is crucial for preserving crawl budget, keeping sensitive directories (like admin areas or checkout pages) private, and ensuring sitemaps are found easily.

How to use this tool:

1. Enter your complete domain or website URL in the input field.
2. Press the "Check robots.txt" button.
3. Review the real-time fetch logs, raw file text, and compliance checklist (detecting sitemap declarations and custom user-agent rules).
