Broken links frustrate visitors and waste the link value you pass to other pages. Enter a URL and the checker collects every unique link on the page — internal and external — and requests each one from our server, following redirects.

Results are split into Broken (4xx, 5xx, DNS failures and timeouts), Redirects (links that work but should point straight at the final URL) and All, with the anchor text so you can find each link in your editor. Optionally include images, and export everything to CSV.

    Update, replace or remove them.

    Update redirected links

    Point them at the final URL.

Frequently asked questions

Do broken links hurt SEO?

A few won't sink rankings, but they waste link equity, hurt user experience and can signal a neglected site.

Can it check my whole website?

It checks one page at a time. Start with high-traffic pages; the XML Sitemap Generator can crawl the site to list them.

What's the difference between a 404 and a 410?

404 means not found; 410 means gone permanently. Both count as broken links.
