A robots.txt generator builds a valid robots.txt file that tells search engine crawlers which parts of your site they may access. You choose which user-agents to address, which paths to allow or disallow, and where your sitemap lives, and it outputs correctly formatted directives. This free tool removes the guesswork from crawl control, giving you a clean file that guides Googlebot and other crawlers without risky syntax mistakes.
What the robots.txt generator produces
The generator produces a complete robots.txt file, formatted with the exact syntax crawlers expect. You specify one or more user-agent lines, such as a rule for all crawlers or a specific bot, then list the paths to allow or disallow. The tool assembles these into valid directives, adds a sitemap reference pointing to your XML sitemap, and can include a crawl-delay where a bot supports it. Common presets help you block folders like admin, cart, or search results without writing rules by hand. The output is plain text ready to save as robots.txt, so you get a correct file even if you have never written crawl directives before.
How to install your robots.txt file
Save the output as robots.txt and upload it to the root of your domain, so it loads at yoursite.com/robots.txt, since crawlers only check that location. On many platforms you can paste the rules into an SEO plugin or site settings field instead of uploading a file directly. Before it goes live, test a few important URLs against the rules to make sure you are not blocking pages you want indexed. Confirm the sitemap line uses the full, absolute URL. After publishing, fetch the file in a search console to verify it parses cleanly. Update it whenever you add sections you want to hide or open, keeping the file short and deliberate.
Robots.txt best practices for crawl control
Keep the file minimal, blocking only what genuinely should stay out of search, such as internal search results or duplicate parameter URLs. Never disallow CSS or JavaScript files that pages need to render, since blocking them can hurt how Google evaluates your layout. Remember that robots.txt stops crawling but does not guarantee a page stays out of the index, so pair it with a noindex tag when you truly want a URL hidden. Always include a sitemap line to help crawlers discover your content. Avoid using robots.txt to protect sensitive pages, because the file is public and lists the very paths you block. Review it after any redesign or migration to catch stray rules.
Frequently Asked Questions
What does a robots.txt file actually do?
It tells search engine crawlers which parts of your site they can and cannot request. Placed at your site root, it helps you keep admin areas, duplicate pages, or staging paths out of crawlers' way while leaving important pages open.
Is this robots.txt generator really free?
Yes. The tool is free to use after creating a Brainito account. You can generate, edit, and download robots.txt files as often as you need, and update your rules whenever your site structure changes in 2026 and beyond.
Will robots.txt remove my pages from Google?
Not by itself. Robots.txt controls crawling, not indexing. A blocked page can still appear in results if other sites link to it. To keep a page out of search results, use a noindex tag or remove the page, and use robots.txt to manage crawl access.
