Fetching robots.txt…
Connecting to the server and analyzing directivesA robots.txt file tells search engine crawlers which pages or sections of your site they can or cannot access.
Directs bots like Googlebot on which URLs to crawl. Use Disallow to block admin areas, staging pages, or duplicate content from being indexed.
Declaring your sitemap URL in robots.txt helps all search engines find and process it automatically, speeding up indexation of new pages.
Blocking CSS/JS files, setting Disallow: / accidentally, or missing the wildcard (*) user-agent rule are the most common robots.txt SEO errors.
Your robots.txt file sits at the root of your domain and quietly shapes how search engines crawl your site. It is the first file Googlebot and other crawlers look for, and a single wrong line can hide your best pages from search — or, just as easily, leave the door open to pages you meant to keep out of the index. Because it is plain text with a deceptively simple syntax, small mistakes slip through easily, which is exactly why it is worth checking.
This tool fetches the live file from any domain, reads every directive the way a real crawler would, and points out the issues that actually affect how your site is crawled and indexed. Instead of squinting at raw text, you get a clear picture of what you are allowing, what you are blocking, and whether your sitemap is properly declared.
Paste any website URL or domain. The tool automatically finds and fetches the robots.txt file from the site’s root.
Each user-agent block, Allow, Disallow and Sitemap directive is read and interpreted exactly as a crawler would.
You get a plain-language report of what is blocked, what is allowed, and any rules that could quietly hurt your SEO.
Use the findings to correct a stray Disallow, add your sitemap, or open up resources you blocked by accident.
On large sites, crawlers only spend so much time per visit. Blocking low-value URLs such as filters, internal search and admin paths keeps that budget focused on the pages you actually want ranked.
Staging environments, internal tools and thank-you pages usually should not appear in Google. A correct Disallow rule helps keep them out of the way.
Declaring your sitemap in robots.txt gives every crawler a direct map of your important URLs, which can speed up how quickly new content gets discovered.
A misplaced “Disallow: /” can wipe an entire site out of search results. A quick check catches that kind of mistake before it costs you traffic.
Google needs to render your pages to understand them. Disallowing your CSS or JS folders can hurt how your pages are judged for layout and mobile-friendliness.
Disallow stops crawling, not access. Anyone can still open the file and read the paths you listed, so never rely on it for anything that needs to stay private.
Leaving out the Sitemap directive means you are hoping crawlers stumble onto your sitemap. Declaring it is a free, easy win.
A leftover “Disallow: /” from a staging build is one of the most damaging errors there is — it tells crawlers to skip everything.
Reputable search engines respect robots.txt, but many scrapers ignore it entirely. Treat it as guidance for good crawlers, never as security.
