Robots.txt Checker/Tester

Fetch and parse robots.txt, test specific URLs against crawling rules, and find configuration issues.

What is Robots.txt Checker/Tester?

The Robots.txt Checker fetches and analyses your website's robots.txt file — the text file that tells search engine crawlers which pages and sections of your site they can and cannot access. It validates the syntax, lists all crawl rules, and lets you test whether a specific URL would be allowed or blocked by the current rules.

Robots.txt is one of the most powerful and most dangerous SEO files on your server. A single misconfigured Disallow rule can accidentally block Google from crawling your entire website. This tool gives you full visibility into your crawl rules before they cause indexation problems.

Why Use Robots.txt Checker/Tester?

The most catastrophic SEO mistake — accidentally blocking your entire site from Google — comes from a robots.txt misconfiguration. Every site owner should regularly verify their robots.txt allows search engines to crawl all important content while correctly blocking internal pages, admin areas, and duplicate content.
