Broken link checker
Free Broken Backlink Checker for Source Pages and Outreach
Use this page when you have a backlink source page, partner page, guest post, roundup, or outreach prospect you want to review. DeadLinkTool checks the links found on that public page and helps you spot broken outbound links, 404s, and opportunities for follow-up. It does not crawl a private backlink database or replace tools like Ahrefs; it is a free page-level checker for backlink cleanup work.

FAQ
Is this the same as a backlink database?
No. This checker reviews the links found on a public page you submit. Use it for backlink source pages, prospect pages, and manual outreach research.
How do I fix a broken backlink?
If a page links to an old URL on your site, set up a relevant 301 redirect or ask the publisher to update the link.
Can I download the backlink check results?
Yes. After a scan, download the filtered results as a CSV report.
