Free Robots.txt Checker
A wrong Disallow rarely shows up as a red banner in your CMS. You notice it when organic traffic dips, AI answers stop citing you, or Search Console says “blocked by robots.txt” on URLs you thought were open.
Most free SEO tools want an account before they show you anything. These don’t. Every tool on this page runs in your browser. Paste a URL, read the result, move on. No signup. No download.
Search Console and Analytics cover the big picture. A desktop crawler handles the deep audit. The gap is the small checks you run all day. Is this redirect clean. Will this title fit in Google. Is this campaign link tracking properly. That gap is what these tools fill, right in the tab you are already working in.
What you’ll find here:
A wrong Disallow rarely shows up as a red banner in your CMS. You notice it when organic traffic dips, AI answers stop citing you, or Search Console says “blocked by robots.txt” on URLs you thought were open.
A broken hreflang cluster doesn’t throw an error. It just serves the wrong language page to the wrong searcher, quietly, for as long as nobody checks.
Check rel=canonical on any URL in seconds. See self-referencing, missing, conflicting, or pointing-elsewhere tags before Google does.
Paste a URL to scan that page for broken links, redirects, and 404s in seconds—or use the Sprout SEO extension to check links on any tab you open.
Preview how your title and meta description will look in Google search results before you publish. Catch truncation and weak snippets early.
Build clean UTM campaign URLs with consistent source, medium, and campaign tags so you can see which marketing channels actually drive traffic.
Check HTTP status codes, response headers, and full redirect chains for any URL. Spot loops, wrong codes, and header issues without leaving your browser.
