External Link Checker

Audit outbound links & spot nofollow / dead ones.

List every outbound (external) link on a page or across your site, check that each destination is alive, and see which links are nofollow, sponsored or ugc. Find dead outbound links that leave readers at a dead end and export the full report as CSV.

Frequently asked questions

What is an external link?

A link to a different hostname than the site you entered. Links back to your own host are internal and shown by the Internal Link Checker.

What does nofollow mean?

rel="nofollow" tells search engines not to pass ranking credit through the link. We also flag sponsored and ugc relationships.

Do broken external links hurt SEO?

They mostly hurt user experience and trust. Fixing or removing dead outbound links keeps your content reliable.

Is this external link checker free to use?

Yes — the external link checker is a free online tool with no sign-up. Enter a URL to list every outbound link and check that each destination is still live.

How do I find broken outbound links on my site?

Run the external link checker in “Whole site” mode and filter by status. It flags every outbound link returning an error so you can fix or remove dead external links across all your pages.

Which links should be nofollow or sponsored?

Paid, affiliate, and untrusted outbound links should use rel="nofollow" or rel="sponsored". The external link checker shows each link's rel attribute so you can confirm they're tagged correctly.

Why audit external links regularly?

External sites move or shut down without warning, leaving dead outbound links that frustrate readers and erode trust. A regular external link check keeps every outbound link working and relevant.
