Enter your domain and get a focused broken-link report. This tool crawls pages on your site, validates discovered internal links, and shows the URLs that need to be fixed first.

What We Check
Page discovery, internal link extraction, HTTP validation, and the broken destinations still linked from your site.
Why It Matters
Broken links interrupt navigation, waste crawl budget, and leave stale paths in your content and templates.
Best Use Cases
Use it after migrations, template changes, CMS cleanups, URL deletions, or navigation updates that may have left dead links behind.
What is a broken link checker?
A broken link checker crawls your site and validates the links it discovers. It helps you find the pages that still point to URLs returning 404, 410, 500, timeout, or other failure states.
This matters because stale internal links do more than frustrate users. They weaken crawl paths, waste link equity, and often signal that redirects or template updates were missed during publishing or migration work.
How this checker works
1. Discover crawlable pages
The tool starts with sitemap and homepage discovery so it can find a focused set of URLs to crawl.
2. Extract internal links
Each discovered page is parsed for internal links that still point to URLs on the same domain.
3. Validate destinations
Discovered links are checked for status failures so broken destinations are separated from healthy pages.
4. Publish a shareable report
Each run creates a public report URL you can share with engineers, marketers, or content owners while fixes are being deployed.
What to fix first after the report loads
Broken links from navigation or templates
These usually affect many pages at once. Fixing a broken header, footer, sidebar, or repeated CTA removes the issue from the widest set of pages fastest.
Links to deleted or renamed pages
Update the source page when the destination moved, or add a redirect when the old URL still has legitimate references and backlinks.
Broken links created during migrations
If the report spikes after a migration or URL cleanup, review redirect coverage and normalize internal links so they point straight to the current canonical URLs.
