Debugging why a page is or isn't being crawled
Robots.txt Generator was built so that anyone, professional or first-time visitor, gets what the page promises (audit, build and test robots.txt, fetch any site's file, control ai & search crawler access, and path-test rules like google does) in seconds. Results are instant and accurate, and nothing needs to be installed or signed up for along the way.
All processing runs locally in your browser, so your files and data never leave your device. Like every tool in the SEO Tools collection, it works across all modern browsers on desktop, tablet, and mobile: same features, same results, on every device.
Robots.txt Generator builds a valid robots.txt file from simple options, choose the crawlers to target, set allow and disallow paths, and add your sitemap location, ready to upload to your site's root.
The most important concept to get right is what robots.txt does and doesn't do. It controls crawling, not indexing. Disallowing a URL stops compliant crawlers from fetching it, but the URL can still surface in search results if it's linked elsewhere, so to actually keep a page out of Google, you use a noindex tag, not a disallow rule.
Used well, robots.txt steers crawlers away from genuinely private or low-value paths (admin areas, internal search, duplicate parameter URLs) and points them to your sitemap. Used carelessly, it can backfire, accidentally blocking CSS, JavaScript, or whole sections harms how Google renders and ranks your pages, so block deliberately.
Remember it must sit at the domain root to be found. Generation, linting and path testing all run in your browser, so the file you are writing is never uploaded; the only thing that leaves your device is the site address you type if you choose to fetch an existing robots.txt to audit, which our server retrieves for you and does not store. Pair it with the Sitemap Validator and Meta Tag Validator to round out your site's crawl and indexing setup.
Place robots.txt at your domain root, anywhere else and crawlers won't find it
To keep a page out of Google, use noindex, not robots.txt disallow (which only blocks crawling)
Avoid blocking CSS/JS or whole sections by accident; over-blocking can hurt rendering and rankings
