Why broken links hurt your SEO
Real Broken Link Checker example: before vs. after
A real result from scanning an old blog post that hadn't been checked in over a year.
- /old-guide-2022 → 404 Not Found
- partner-site.com/resource → 404 Not Found
- docs.tool.io/api → redirected 3 hops
- 12 healthy links
3 dead links and a 3-hop redirect chain were quietly wasting crawl budget and frustrating readers who clicked through.
- /old-guide-2022 → updated to /guide-2026
- partner-site.com/resource → removed, dead resource
- docs.tool.io/api → updated to direct link
- 15 healthy links
All broken links fixed or removed, and the redirect chain flattened to a single direct link, no more wasted crawl budget or dead ends for readers.
