FAQ
How does the Broken Backlink Finder work?
Paste backlink data with URL + HTTP status code (and optional anchor + source). The tool categorizes each status code into 2xx/3xx/4xx/5xx, flags broken links (4xx/5xx), and scores each broken link for reclamation opportunity — 404/410 with anchor and source scores highest because they're the easiest to reclaim.
What counts as a 'broken' backlink?
Any URL returning a 4xx (client error) or 5xx (server error) status code. The exception is 429 (Too Many Requests / rate-limited), which is treated as temporary and not broken. 2xx and 3xx are healthy.
How is the reclamation opportunity score calculated?
Base 50 for any broken link. 404 adds +30, 410 adds +25, 5xx adds +10, 403 adds +5. Having an anchor text adds +10 (easier to recreate matching content). Having a source domain adds +10 (easier outreach). Capped at 100.
What input format does it accept?
CSV with header (url, status_code, anchor, source_url, source_domain) or headerless rows in that same column order.
What extra features does this tool have compared to others?
(1) Status code categorization (2xx/3xx/4xx/5xx). (2) Broken link detection (4xx/5xx, except 429). (3) Reclamation opportunity scoring (0-100). (4) Anchor text per broken link. (5) CSV export. (6) Plain-text report copy. (7) Stats summary. (8) History (localStorage, last 20). (9) Shareable URL. (10) Full status code reference (200/301/404/410/500/etc.).
Is my data sent anywhere?
No. All analysis runs locally. History is stored in localStorage on this device only.
