robots.txt validator

The robots.txt file, located at the root of a website, provides the first set of instructions that search engine crawlers (like Google, Bing, etc.) receive. Its role is to give them clear directives about which sections of the site they are allowed or forbidden to "crawl." A proper configuration of this file is therefore essential to effectively guide bots to your important content and deny them access to irrelevant or sensitive areas. Our free robots.txt validation tool allows you to quickly check the syntax and validity of these directives.

A simple syntax error or a misconfigured rule in the robots.txt file can have significant consequences for your online visibility, ranging from the accidental blocking of strategic pages to the crawling of useless resources that consume your crawl budget. By analyzing your file's structure and the logic of your Allow and Disallow directives, this validator helps you pinpoint potential errors. This allows you to ensure that your instructions are correctly interpreted by crawlers, guaranteeing that your site is explored and indexed in perfect alignment with your SEO goals.
