About Robots.txt File Generator

A robots.txt file tells search engine crawlers which parts of a site they’re allowed or disallowed from accessing — a simple, plain-text file, but one that’s easy to write incorrectly since a single misplaced rule can accidentally block far more than intended.

This tool generates a correctly-formatted robots.txt based on your specified rules, avoiding common syntax mistakes that could unintentionally block search engines from your entire site.

Worth knowing directly: robots.txt is a voluntary convention respected by well-behaved crawlers (like Google’s), not an actual access-control mechanism — it doesn’t prevent access, it requests that compliant crawlers not access specified areas.

Frequently Asked Questions

How do I create a robots.txt file for my website?

Choose Allow all, Block all or Custom rules. For custom rules, enter a user-agent and the paths to disallow or allow, then add your sitemap URL if you have one. Click Copy or Download robots.txt and upload it to your site.

How do I set up robots.txt?

Save the generated file as robots.txt and place it in the root of your domain so it loads at yourdomain.com/robots.txt. A subdomain needs its own file. Then open that URL in a browser to confirm it is live.

What is robots.txt?

Robots.txt is a plain text file at the root of a website that tells search engine crawlers which paths they may or may not crawl. It uses User-agent, Disallow, Allow and Sitemap lines. Well-behaved crawlers follow it, though it is a request rather than enforcement.

What is robots.txt used for?

It is used to manage crawling, for example keeping bots out of admin or internal search pages and pointing them to your sitemap. It does not keep a page out of search results, as a blocked URL can still be indexed if linked, and it is not a security tool.
