Dead link checker: find and fix dead links fast

A dead link checker tells you which links on a page lead nowhere. If you run a site and want a quick answer for one page, the dead link checker from seogeoaeo.ai reads that page, tests the links that point back to your own site and lists the ones that fail.

Here is what a dead link is, why it matters and how to clear one out in a couple of minutes.

What counts as a dead link

A link is dead when the page it points to no longer loads properly. In practice, the server answers with an error code instead of the page:

404 Not Found: the page is gone or the address has a typo.
410 Gone: the page was removed on purpose.
500 and other 5xx codes: the server failed while answering.

A visitor who clicks one of these hits a dead end. A search crawler that follows it wastes a request and learns nothing new about your site.

Why internal dead links deserve attention first

Links from one of your pages to another are fully in your control, so they are the easiest to fix. They also carry readers through your site. A dead link in the middle of a popular post or in the main menu breaks that path for everyone who reaches it.

Run the check

Open the Broken Internal Link Finder on seogeoaeo.ai.
Paste the public URL of the page you want to test.
Run it. The cost is 15 credits, shown before you start.
Read the list of links that came back with a 4xx or 5xx error.

The checker looks at links in the main content before navigation links, so the results lead with the links readers are most likely to click.

Fix it

Situation	Do this
The page moved	Change the link to the new address
Lots of pages link to the old address	Redirect the old address to the new one
The page is gone for good	Remove the link or swap in a related page

Then publish and run the same page again to confirm the list is empty.

Know its scope

This is a one-page tool. It does not crawl the full site, does not test links to other websites and does not see links that are added by JavaScript after the page loads. For a wider sweep, seogeoaeo.ai's Orphan Page Finder crawls from your homepage and reports broken internal links too. If you need every outbound link on a large site checked, a free whole-site option such as the Ahrefs broken link checker may suit that job better. For the everyday task of keeping your own pages free of dead internal links, seogeoaeo.ai is the simplest place to start.

Quick habit

Make a dead link check part of any change that renames or deletes a page. It takes a minute per page and saves readers from hitting a wall. You can also browse the other seogeoaeo.ai checks for related site structure problems.
