Create a clean robots.txt, test your live file, or validate pasted rules before putting them on your website.
Check whether a specific URL is allowed or blocked by your live robots.txt rules.
Find sitemap directives and identify missing or invalid sitemap URLs.
Spot unsupported directives, malformed rules and potentially risky crawl blocks.
Use this free robots.txt tool to create a robots.txt file, test your live file, validate directives, and check whether Googlebot can crawl a specific URL. Robots.txt controls crawler access; it is not a direct indexing or ranking control.
/robots.txt.Search-engine crawlers use robots.txt rules to determine which URLs they may crawl. Google supports fields including User-agent, Allow, Disallow and Sitemap. Google also documents a 500 KiB robots.txt size limit.
A robots.txt file contains crawler rules for a website. It is normally placed at the root of the host, such as https://example.com/robots.txt.
Not necessarily. Robots.txt controls crawling. A URL can still potentially appear in search if Google knows about it from other sources.
Disallow: / under a matching User-agent group blocks crawling of all URL paths covered by that group. Use it carefully.
Adding a full sitemap URL can help crawlers discover your sitemap. This tool can generate a Sitemap directive for you.
No. The generator and validator run without a paid API. The live tester fetches the robots.txt file directly from the target website.
