Build a valid robots.txt file with an easy rules builder
The Robots.txt Generator helps you create a correct robots.txt file without memorizing syntax. Add user-agent groups, specify allow and disallow paths, set an optional crawl delay, and include your sitemap line. The tool assembles a clean, valid file in real time that you can copy or download and drop straight into your website's root directory.
Robots.txt is the first file most search-engine crawlers request when they visit your site, and it controls which areas they may explore. Used well, it keeps low-value or private paths out of crawl queues, protects staging areas, conserves crawl budget on large sites, and points bots to your sitemap so new content gets discovered faster. Used carelessly, a single stray rule can hide your whole site from search.
This builder reduces that risk by structuring rules into clear groups and generating well-formed output you can review before publishing. Whether you run a small blog, a busy store, or a large content platform, you can define exactly how different crawlers behave. Everything is generated locally in your browser with no signup, so your site structure stays private.
