Every broken backlink is wasted endorsement: a real page vouched for a URL of yours that now returns a 404 or loops through redirects. Those citations already survived editorial approval — the hardest part of link earning — so recovering them costs less than prospecting fresh ones. The right tools to find broken backlinks turn that arithmetic into a repeatable process instead of luck.
Precision matters here. A broken backlink points at a dead target; a lost backlink simply vanished from the source page — edited away, deindexed, blocked. Tools track the two differently, and conflating them muddies recovery priorities.
Quick Answer: Ahrefs' Broken Backlinks report pairs referring pages with the dead URLs they point to — on your site and competitors', enabling reclaim outreach — while Semrush tracks newly lost links day by day.
Broken Versus Lost Backlinks
- Broken — the linking page still exists but its target returns an error or redirects; fixable instantly with a redirect or revived page.
- Lost — the link itself disappeared from a live source page; recovery requires outreach or acceptance.
- Both decay silently, which is why monitoring cadence matters more than dashboard polish.
What Matters in a Recovery Tool
- Crawl recency — stale indexes waste outreach on links already restored elsewhere.
- History depth — knowing a link existed six months ago enables archaeology on older losses.
- Referrer metrics for triaging which reclamation pitches deserve effort first.
- Clean exports so outreach teams work from lists, not screenshots.

Tool Reviews
Ahrefs
Site Explorer's Broken report matches referring pages with the dead targets they point at. Flip the lens onto competitor domains and the same report becomes a reclaim-prospect list — their dead endorsements are pitchable to webmasters who demonstrably link out. Free Webmaster Tools covers verified sites only. Details at ahrefs.com.
Semrush
Backlink Analytics charts lost and newly found links daily, while Backlink Audit flags targets returning errors — strong for maintaining ongoing recovery cadence across many clients.
Majestic
Deep historical indexes show links that once existed and later vanished, making it the archaeology tool for long-window recovery projects newer indexes cannot see.
Linkody
Lightweight daily emails listing new and lost backlinks at budget pricing — sensible monitoring between heavy quarterly audits.
Google Search Console
The free baseline: export your external link inventory and intersect it with server-side 404s. It never labels links broken, so pairing with logs or a crawler is essential.
Workflow Tip: Reclaim Before You Rebuild
Sort broken links by referring-domain authority. For each dead target choose: revive an equivalent page, or redirect to the closest living resource so endorsement transfers. Then email referrers whose context suggests willingness — resource-page curators respond well to "your list links to a guide that moved." Reply rates stay modest, yet a handful of restored editorial links beats a month of cold prospecting.
Key Takeaways
- Broken backlinks are pre-approved citations — the cheapest authority available to recover.
- Distinguish broken targets from lost links; each needs different treatment.
- Redirect dead targets to closest equivalents so remaining equity flows immediately.
- Competitors' broken links double as your outreach prospect list.
