How to use the broken link checker

Three steps, no sign-up.

  1. 1

    Enter a URL

    Type or paste the address to check, then press Check or Enter.

  2. 2

    Fix the broken links

    Broken links come first, with their status code and where redirects end.

  3. 3

    Copy the result

    Copy the findings in one click. We don't store the URL or the page.

Broken Link Checker: what to know

The broken link checker tests every link on one page. Our server reads the page's HTML, collects up to 100 unique links and images (links first), and requests each one, headers only, to see what it returns. Each link is marked as working, redirecting, broken (a 4xx or 5xx error, a domain that doesn't resolve, a refused connection or a timeout), needing a look (sites that refuse automated checks with codes like 403 or 429), skipped or not checked, with the status code, where redirects end, whether it's internal or external, and whether it carries nofollow, ugc or sponsored.

Checks run five at a time with 5 seconds per request, trying a light HEAD request first and a normal request when a server refuses HEAD, and the whole check stops after about 25 seconds, so a page with many slow links may show some as not checked. Links to private or local addresses are skipped without being requested. The page is read as raw HTML without running JavaScript, so links added by scripts don't appear, and response times are measured from our server. Only the page URL leaves your browser; the URLs and the page aren't stored or logged. Fix broken links by pointing them at the right page, and update redirecting links to the final URL.

Popular uses

  • Finding dead outbound links on an old blog post
  • Checking a page's internal links after a site migration
  • Finding missing images that return 404
  • Reviewing which links on a page carry nofollow or sponsored
  • Updating links that go through redirect chains

Tips for the best result

  • Open links marked Needs a look in a browser before changing them: many sites block automated checks.
  • Update internal links that redirect so they point straight at the final URL.
  • When a page you link to is gone, link to a good replacement or remove the link rather than leaving it.
  • For a whole site, run your crawler; this tool checks one page at a time.

Frequently asked questions

Up to 100 unique links and images on the one page you enter, links first, read from the raw HTML without running JavaScript. Our server checks them five at a time, headers only, with 5 seconds per request; links it has no time left for are marked "Not checked". It doesn't crawl the rest of your site.

Some sites refuse automated requests, answering 401, 403, 429 or a made-up code such as 999 even though the page works for people. Those links are marked "Needs a look" rather than broken: open them in a browser to be sure.

Not directly: Google says 404 errors for pages that don't exist don't hurt how the rest of a site does in Search. But a broken link is a dead end for visitors, and a broken internal link can keep Google from finding the page it should point to. Update links to moved pages with the new URL.

No. Your browser sends only the page URL; our server requests the page and each link, then returns the results to your browser. The URLs and the page aren't stored or logged, private and local addresses are skipped without being requested, and a rate limit stops the tool being used to flood other sites.

No. The text, HTML, files and images you paste or open are processed on your device and are not sent to our server or stored. The five URL tools (SEO audit, indexability checker, redirect checker, HTTP header checker and broken link checker) are the exception: they send the URL you enter to our server, which requests that public page (and, for the broken link checker, each link on it) and returns what it received to your browser to check. The URL and the page aren't stored or logged. The optional Import from URL in the meta tag, Open Graph and Twitter card generators works the same way.

Yes. Every tool is free with no sign-up and no limits on use. Clearly labeled ads keep it that way.

They help you get the details right: tags that are complete and valid, previews that read well, files crawlers can parse. No tool can guarantee rankings; those depend on your content, your site and how search engines evaluate them.
