Free Robots.txt Generator & Tester

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.

How to use the Robots.txt Tool

  1. Use Generate to create a basic robots.txt file and add your sitemap.
  2. Use Test Live File to fetch your website's current /robots.txt.
  3. Use URL Tester to check a specific URL against the selected crawler.
  4. Use Validate Rules before publishing a manually edited robots.txt.

Why robots.txt matters for technical SEO

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.

Frequently Asked Questions

What is a robots.txt file?

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.

Does robots.txt block a page from Google Search?

Not necessarily. Robots.txt controls crawling. A URL can still potentially appear in search if Google knows about it from other sources.

What does Disallow: / mean?

Disallow: / under a matching User-agent group blocks crawling of all URL paths covered by that group. Use it carefully.

Should I add my sitemap to robots.txt?

Adding a full sitemap URL can help crawlers discover your sitemap. This tool can generate a Sitemap directive for you.

Does this tool need an API?

No. The generator and validator run without a paid API. The live tester fetches the robots.txt file directly from the target website.
