Free broken link checker

What this tool checks

• Links to your own pages

  Links on the same site as the page (same protocol and domain), collected from the page as the browser renders it, with links in the navigation tested first.

• Up to 12 internal and 5 external links

  The first 12 unique links to your own pages and the first 5 links to other websites. Links to your own subdomains, email, phone and javascript: links are skipped, and #section links count as the page they belong to.

• Broken means an error or no answer

  An internal link is broken when it returns 400 or higher or doesn't answer within 8 seconds. Redirects are followed one hop at a time (up to 5). For other websites, 401, 403, 405, 429 and 999 count as inconclusive, because many sites refuse automated visitors.

• JavaScript errors

  Uncaught errors thrown while the page loads, which often mean a menu, form or slider doesn't work.

• Console errors

  Errors the page logs to the browser console.

• Form checks (never submitted)

  Each form's markup: password fields on an HTTP page or sent over http://, passwords sent with GET, placeholders used as the only label, missing labels, input types, autocomplete hints, external actions, a CSRF-style token and a submit button.

• Files that fail to load

  Your own scripts, stylesheets, images and fonts that fail or return an error status while the page loads, and images that load broken.

How the check works

What this tool does not check

• Every link on the page

  Only the first 12 internal and 5 external links are tested. Links on other pages need a site scan.

• Sites that block automated visitors

  Some sites refuse checkers with 403 or 429. We treat those as inconclusive rather than broken.

• Whether your forms actually work

  Forms are never submitted, so we can't test what happens after sending, server-side validation, CSRF protection or spam filtering.

• Buttons and interactions

  Nothing is clicked, so errors that happen only after a tap — opening a menu, adding to cart — aren't caught.

Common problems we find

• Pages that were moved or deleted

  Old blog posts, discontinued products or renamed pages that still have links pointing to them.

• Typos in links

  A missing letter or an extra slash in a hand-typed link.

• Links left over from a redesign

  Old URL structures or links to a staging copy of the site.

• Server errors

  Pages that return a 500 error because of a broken plugin or template.

• JavaScript that breaks on load

  A missing library, a script loaded in the wrong order, or code that expects an element that isn't on this page.

• Files that fail to load

  Images, fonts or scripts that return 404 after a redesign or a plugin update.

• Insecure or unlabelled forms

  Login forms on pages still served over HTTP, search boxes that rely on placeholder text instead of a label, and email fields using type="text".

How to fix them

1. 1

   Update or remove the link

   If the page moved, change the link to its new address. If it's gone for good, remove the link or point it to the closest useful page.

2. 2

   Redirect old addresses

   Set up a permanent (301) redirect from the old URL to the new one so bookmarks and links from other sites keep working too.

3. 3

   Fix JavaScript errors from the top

   Open the page, then your browser's developer tools (F12) and the Console tab. The first error often causes the rest, so fix that one first.

4. 4

   Re-check after publishing

   Run the check again after changes, and after moving or deleting pages.

5. 5

   Tidy up your forms

   Serve and submit forms over HTTPS, use method="post" for anything with a password, give every field a visible label, and use the right type and autocomplete values (email, tel, current-password) so phones and password managers help.
