    Backlink Reclamation Finder: Fix 404 Pages That Still Have Backlinks (301 Map)

    Example session with this skill installed

    Here's my Search Console 'Top linked pages' export for acme-dental.com. Which pages with backlinks are broken, and give me the redirects.

    • Read your context and instructions
    • Compiled the backlink reclamation finder
    • Generated the data export

    Backlink Reclamation report: https://acme-dental.example

    Checked 2026-10-30 by Backlink Reclamation Finder 1.0 (Cygnix Labs). Export: per-target (referring domains), per-link (source -> target), Google Search Console Links: per-target (referring domains); 17 rows, 14 linked-to URLs on this site.

    Summary

    9 linked-to URLs are broken (404/410/5xx/soft-404/redirect to homepage), carrying

    81 referring domains of links you already earned.

    7 redirects ready to deploy, 0 to review, 3 with no close replacement (recreate the page or ask linkers to update).

    • 2 redirect chains/temporary redirects (18 referring domains): point them straight at the final page.

    • 2 linked-to URLs are fine. 1 skipped (blocked by robots.txt for this checker).

    • 1 URL(s) return 5xx: fix the server error first; a redirect would hide a live page.

    Do this next

    1. Deploy the HIGH/MEDIUM redirects (they are 301s to the closest live page, not the homepage). Review the # REVIEW lines by hand.
    2. For pages with no close match and many referring domains, recreate the content at the old URL: it is cheaper than earning those links again.
    3. Collapse chains so each old URL is one hop from its final page, and swap temporary (302/307) redirects for 301s.
    4. Fix 5xx pages at the server; do not redirect them.
    5. Re-run this check after deploying, then in Search Console use URL Inspection on the top 5 old URLs.

    Checks are polite: identifies as CygnixBacklinkReclaim, obeys robots.txt, waits between requests. Referring-domain counts come from your export; they are not re-verified.

    About this skill

    Free backlinks you already earned. Find the pages other sites link to that are now broken on your site, and get a ready 301 redirect map ranked by referring domains.

    After a redesign, migration or content cleanup, links from other sites keep pointing at URLs that now 404. That link equity is lost until you redirect them. Site crawlers miss this because they only follow your internal links. This skill starts from your backlink export instead.

    What it does

    • Reads any backlink export: Google Search Console Links (Top linked pages, free), Ahrefs Best by links / Backlinks (UTF-16 tab files work as is), Semrush Indexed pages / Backlinks, Moz, Majestic, or a plain URL list. Combine several. Per-link exports are grouped by target and counted by unique referring domains.
    • Checks every linked-to URL live: 404, 410, 5xx, soft 404 ("not found" pages that return 200, plus a site-wide soft-404 probe), redirects to the homepage (Google treats these as soft 404s), redirects that end in a 404, redirect chains (2+ hops) and 302/307 temporary redirects.
    • Finds the best live replacement from your sitemap (index sitemaps and WordPress/Yoast/Rank Math sitemaps followed) and homepage links, scored on slug words, slug similarity, same section, and the old title or anchor text. Top candidates are fetched to confirm they are live. It never suggests the homepage.
    • Ranks everything by referring domains, so the first redirect you deploy recovers the most link equity.

    Output

    • redirects.htaccess (Apache/LiteSpeed, including query-string URLs), redirects-nginx.conf, redirect-map.csv (imports into WordPress Redirection, Rank Math or Yoast). HIGH/MEDIUM matches are active; low-confidence lines are commented # REVIEW.
    • report.md (client-ready): broken URLs and the referring domains they carry, chains to collapse, pages with no replacement and the sites to ask for a link update, next steps.
    • findings.csv and result.json.

    Stdlib Python 3.9+, no installs, no API keys, no tool logins. Polite checker: identifies itself, obeys robots.txt, 1 s between requests, checks the top 200 URLs by default (max 1000). 16 tests on a fake site included.

    Pairs with our Site Migration QA, Plan 301 Redirects and Spam Backlink Triage skills.

    Checks your site as it is now, from outside (no login). Referring-domain counts come from the export and are not re-verified. Replacement matching is by URL slug and title, so heavily renamed pages may need a human choice. JavaScript-only redirects are not followed.

    What's inside

    Frequently Asked Questions

    No. The free Search Console Links export (Links > Top linked pages > Export) works. Ahrefs, Semrush, Moz and Majestic exports also work, and you can pass several at once.

    Broken link checkers crawl your own internal links. This starts from links on other sites (your backlink export), so it finds broken pages that nothing on your site links to anymore, and ranks them by referring domains.

    Never. Google treats that as a soft 404. Each broken URL is matched to the closest live page by slug, section and title; low-confidence matches are commented out for review, and pages with no match get a 'recreate or ask linkers' note.

    Apache/LiteSpeed (.htaccess, including query-string URLs), nginx (location blocks), and a CSV that imports into the WordPress Redirection plugin, Rank Math or Yoast.

    No. Referring-domain counts come from your export. The skill checks your own site's target URLs and finds replacements.
