Build a valid robots.txt to control how search engines crawl your site.
The robots.txt Generator helps you create a valid robots.txt file visually. Allow or disallow specific paths, target individual crawlers, set a crawl-delay, and add your sitemap URL, then copy a file that tells search engines how to crawl your site. It turns the exact syntax rules of the robots exclusion standard into a few simple choices.
robots.txt is a plain-text file at the root of your domain that gives instructions to web crawlers. It can allow or disallow access to paths for all bots or for named ones like Googlebot and Bingbot, suggest a crawl-delay, and point to your sitemap. Well-behaved crawlers read it before fetching your pages, so it is your first line of control over crawl budget and coverage.
A common and costly misunderstanding is that Disallow hides a page from search results. It does not. Disallow tells crawlers not to fetch a path, but a disallowed URL can still be indexed if other sites link to it — Google just shows it without a description. To keep a page out of search results entirely, you need a noindex directive on the page itself, which means the crawler must be allowed to fetch it. Understanding this difference is essential to using robots.txt correctly, and it is where many accidental SEO problems begin.
Block an admin area but allow everything else, and declare a sitemap:
User-agent: *
Disallow: /admin/
Allow: /
Sitemap: https://example.com/sitemap.xmlThis tells every crawler to avoid /admin/, permits the rest of the site, and points them to your sitemap so new pages are discovered quickly.
The single most damaging error is a stray Disallow: /, which blocks crawlers from your entire site — always double-check you have not left one in after testing. Do not rely on robots.txt to hide sensitive content, since the file is public and listing a secret path effectively advertises it; use authentication instead. Always include your sitemap line so crawlers find new content quickly, and after publishing, verify the file with a search engine's testing tool to confirm your important pages are still crawlable. Remember too that robots.txt is a request, not enforcement: reputable crawlers obey it, but it does not secure anything.
At the root of your domain, e.g. example.com/robots.txt, so crawlers can find it.
No — it controls crawling, not indexing. Use a noindex directive to reliably keep a page out of search results.
Yes — the generator includes a field for your sitemap URL.
Yes — set rules for all crawlers or for named user-agents like Googlebot.
No — robots.txt is public, so use authentication for anything sensitive.
No. The file is generated entirely in your browser.
Pair it with the .htaccess Generator to configure redirects and server behaviour.
