Find the dead links before your visitors do
Links rot. Pages move, sites disappear, and a link that worked when you wrote it now leads to a 404. This checker scans a page for broken links so you can find and fix them, rather than leaving visitors and search engines to hit dead ends.
Why broken links cost more than a bad click
A broken link is a small failure with outsized effects. For a visitor it is a dead end that erodes trust in the whole page. For search engines, links that lead nowhere signal a poorly maintained site and waste the crawl budget that could have gone to real pages. An internal broken link is worse than an external one, because it means part of your own site is unreachable through that path.
Regular checks keep a site healthy
Link rot is continuous, so a page that was clean six months ago may not be now. Periodically scanning key pages catches the breakages as they happen rather than letting them accumulate. Fixing a broken link is usually a one-line change; finding it is the hard part, which is what the checker does.

Frequently Asked Questions
What is a broken link?
A link that leads to a page that no longer exists, returning a 404 or similar error. It happens as pages move or sites disappear over time.
Why do broken links hurt SEO?
They signal a poorly maintained site to search engines and waste crawl budget on dead ends. Internal broken links also leave parts of your own site unreachable.
How often should I check?
Periodically, because link rot is continuous. A page that was clean months ago may have accumulated broken links since, especially if it links to external sites.
Are internal or external broken links worse?
Internal ones are worse, because they mean part of your own site cannot be reached through that path, though both should be fixed.
What does the checker report?
The links on the page that fail, so you can update or remove them.
