Start here · What is a broken link?
A broken link points to a URL that no longer works, often returning a 404 or 500 status code.
Broken links frustrate users and waste crawler attention. They can also weaken internal linking if important pages are no longer reachable.
Fixing broken links is one of the simplest SEO maintenance wins because the action is usually clear: update, redirect, remove, or replace.
When to use this tool
- Routine site maintenance
Run checks monthly or after content pruning, migrations, plugin changes, or large publishing batches.
- Editorial QA
Check an article before publication so citations, product links, and internal links do not lead to dead pages.
- Migration cleanup
Find internal links still pointing to old URLs after redirect maps and template changes.

Short tutorial
Follow in order the first time you use the tool; later you can skip to the step you need.
- Step 1 - Enter a URL or URL list
Start with important pages: home, category, top traffic articles, or recently migrated sections.
- Step 2 - Sort by status code
Fix 404 and 500 errors first. Then review redirecting links that should point directly to the final URL.
- Step 3 - Choose the right fix
Update the link, add a redirect, replace the destination, or remove the link if it no longer serves users.

FAQ
- Do broken external links hurt SEO?
- They are usually not a direct penalty, but they hurt user trust and page quality. Fix important ones.
- Should I redirect every broken URL?
- Redirect when there is a relevant replacement. If no useful replacement exists, a 404 or 410 can be acceptable.
- How often should I check broken links?
- Check after major changes and on a recurring schedule. Larger sites need more frequent monitoring.
