Find the dead links on any page.

Up to 30 links from the page you give it, checked in parallel so results come back in seconds rather than minutes. If the page has more than 30 links we tell you how many we skipped. This is a single-page checker by design — a full-site crawl is a different job and we do those as part of a technical SEO engagement.

Anything returning a 4xx status (usually 404 Not Found or 403 Forbidden) or a 5xx server error, plus links to domains that no longer resolve. We list redirects separately because they are not broken — but a link that redirects is still a link worth updating to point at the final destination.

Two reasons. Visitors who hit a dead link usually leave rather than hunt for the right page. And search engines spend a limited amount of time crawling your site — every request that ends in a 404 is budget spent on nothing, which matters more the larger your site gets.

A few servers deliberately reject automated requests, or block the HEAD method we use to check status without downloading the page. If a link shows an error but loads fine for you, that is almost always what happened rather than a genuine fault.

Yes — both internal and external links are checked, and the table marks which is which. External links breaking is very common, because you have no control over whether someone else keeps their page alive.
