Broken Link Checker — 404 Error & Dead Inbound Link Auditor
Detect broken inbound backlinks and 404 dead links pointing to your domain to reclaim lost PageRank equity and execute broken link outreach.
Link Equity Decay & The Cost of Broken Backlinks
Over time, websites undergo URL restructuring, CMS migrations, category consolidation, and content pruning. When an external authoritative domain links to a URL on your site that now returns a 404 Not Found HTTP response, 100% of the PageRank link equity from that referring domain is permanently lost.
Broken Backlink Reclamation is the process of auditing dead inbound links and implementing permanent 301 Redirects to the most relevant surviving page on your domain. This immediately restores accumulated PageRank authority, improves crawl budget efficiency, and eliminates 404 drop-offs for human referral traffic.
Broken Link Severity & Remediation Matrix
| Broken Link Scenario | Equity Impact | Recommended Fix | Time to Recovery |
|---|---|---|---|
| High-DR Media Link (404) | Severe (DR 70+ authority trapped) | 301 Redirect to matching live category or pillar guide. | Immediate on next Google crawl. |
| Typo in Inbound URL | Moderate | 301 Redirect typo URL to correct canonical destination. | Instant recovery. |
| Competitor 404 Asset | High Outreach Opportunity | Execute broken link outreach pitch to referring webmaster. | 1 to 3 weeks outreach cycle. |

Frequently Asked Questions (FAQs)
Google has confirmed that 301 redirects pass full PageRank equity without dilution, provided the target destination is topically equivalent to the original URL.
No. Redirecting unrelated broken URLs to your homepage is classified by Google as a 'Soft 404' and link equity is nullified. Always redirect to a relevant matching subpage.
A 301 is a permanent redirect that transfers link equity and canonical status. A 302 is temporary and preserves signals on the original URL.
