Broken Link Reclamation
Last updated
Broken link reclamation is the least glamorous and often highest-return link work available, because it recovers value you have already earned rather than chasing new links from scratch. When another site links to a page of yours that no longer resolves, or names your brand without linking, the hard part, someone deciding you were worth referencing, is already done. Reclamation is just repairing the connection.
It sits within link building but inverts its usual direction. Standard link building creates new links; reclamation restores links that existed or should exist. The return per hour is usually far higher, which is why it belongs near the top of any link programme rather than as an afterthought.
What are the three types of link reclamation?
Inbound links pointing at your 404s. Another site links to a URL of yours that has since moved or been deleted, so the link now lands on a 404. The link equity is stranded. This is the most valuable type to fix because the external link already exists and passes authority; you only need to reconnect it to live content.
Your own broken links. Internal links and outbound links on your site that point at pages, yours or others’, that now 404. These do not lose you inbound equity, but broken internal links waste crawl paths and hurt user experience, and broken outbound links date your content.
Unlinked brand mentions. A site names your brand, product, or founder in text but does not link to you. The editorial endorsement is there; the link is not. A short, polite outreach note asking for a link often succeeds precisely because the author already chose to mention you.
How do you fix inbound links hitting a 404?
The fix is almost always a redirect, not outreach. When you find an external link pointing at a dead URL, add a 301 redirect from that old URL to the most relevant live page, ideally the direct successor of the content that used to live there.
The workflow:
- Find the broken inbound links. Use a backlink tool (Ahrefs, Semrush, or Search Console’s links report cross-referenced against your 404s) to list external links whose target URL returns a 404.
- Match each dead URL to its best live replacement. The closest topical equivalent, not the homepage. A homepage redirect passes far less relevance, and Google’s site-move guidance warns against redirecting many old URLs to “one irrelevant single URL destination, such as the home page”, which it says might be treated as a soft 404.1
- Add a 301. This reconnects the external link to live content and restores the equity flow, with no need to contact anyone.
- When nothing equivalent exists, return a 404 or 410. Google’s guidance for a removed page with no replacement is to serve one of those codes rather than redirect somewhere loose, because they tell search engines the content should not be indexed.2 The link equity is lost either way, but a useful custom 404 page still recovers the visitor, and the HTTP status codes reference covers when 410 is the more accurate code. Contacting the linking site to update or remove the link is the remaining option, and unlike a redirect it depends on someone else acting.
This is also why redirects matter during a site migration: a redirect map that preserves old URLs is bulk link reclamation done in advance.
AI assistants send visitors to URLs that do not exist
A backlink tool will not show you this one. In September 2025, Ahrefs checked the HTTP status of 16 million URLs cited by ChatGPT, Perplexity, Copilot, Gemini, Claude and Mistral, and found that “AI assistants send visitors to 404 pages 2.87x more often than Google Search”. ChatGPT was the worst, with 1.01% of clicked URLs and 2.38% of all cited URLs returning a 404, against baselines of 0.15% and 0.84%.3
SE Ranking repeated the test in December 2025 on a separate sample of 145,463 ChatGPT-cited URLs and found 1.22% returning a 404, against 0.65% for Google’s organic results and 0.56% for AI Overviews.4 Both are tool companies measuring their own panels, so the agreement between them counts for more than either figure.
Ahrefs suggests two causes. Some cited URLs were valid once and have since been deleted or moved without a redirect, which is ordinary link rot surfacing through a new channel. The rest are true inventions: URLs that “fit the expected pattern of URLs for a given website, but don’t actually exist”.
Both are worth reclaiming where the traffic justifies it, and Ahrefs is explicit about the scale: hallucinated URLs “impact a small percentage of an already-small-percentage of an average website’s traffic”, so it recommends filtering to 404s that are actually receiving visits before redirecting anything. Where the guess is reasonable and a relevant live page exists, honouring it costs one redirect: an assistant guessing /pricing/ or /blog/seo-guide/ is telling you what a reader expected to find. At volume the answer changes, and Ahrefs’ own alternative to “a spiderweb of 301 redirects” is to make the 404 page itself useful, with a short list of your most-visited pages.3
The discovery route differs from the rest of this article. These URLs have no backlinks, so they appear in no backlink report. Find them in analytics or server logs by filtering 404s for AI-assistant referrers, or by reviewing 404s with traffic but no referring domains.
How do you find your own broken links?
The third type is the cheapest to find and the least urgent to fix, because no inbound equity is at stake. Two sources cover it:
- A site crawler. Screaming Frog or Sitebulb crawls your site and reports every internal and outbound link returning a 404, with the pages each one sits on. This is the only way to see broken outbound links, which no Google report covers.
- Search Console’s Pages report. It shows URLs Google tried to crawl and could not, which catches internal links to dead pages even where your crawler misses them. Read it as triage rather than a defect list: many non-indexed URLs are deliberate, and crawl errors covers which reasons are genuine problems.
Fix internal breaks by repointing the link at the live URL rather than by redirecting, because an internal link is yours to edit and a redirect adds a hop you do not need. Broken outbound links are a judgement call: replace the source if an equivalent still exists, and remove the link if the claim no longer needs it.
Where unlinked mentions fit in
Unlinked mentions are found by monitoring, then converted by outreach. Brand mentions covers the monitoring tools and the outreach pattern in full; what follows is how the work sits inside a reclamation sweep.
Find them. Set up alerts for your brand name, key product names, and prominent people (founders, spokespeople) so new mentions surface as they publish. A mention-monitoring tool or a simple alert service works; the goal is a steady feed of new references to review.
Qualify them. Not every mention is worth pursuing. Prioritise mentions on relevant, credible sites where a link would genuinely help the reader. Skip low-quality sites and contexts where a link would look forced.
Ask well. A short, specific note works best: point to exactly where you are mentioned, thank them genuinely, and ask if they would consider linking the mention to the relevant page, offering the URL. Because the author already chose to reference you, the ask is small and the success rate is high relative to cold link outreach.
An unlinked mention already carries value. AI systems read the text of a page, not only its link graph, so a credible site describing what you do, by name and in context, contributes to how you are recognised as an entity and to whether you surface in AI answers, whether or not anyone adds the anchor. Two practical consequences follow: a mention retains value when outreach fails, so it should not be written off, and a page whose mention is already doing that work is a lower priority for a link request than one where it is not.
Why is reclamation worth prioritising?
The economics are simply better than most link building. The endorsement already exists, so you are not persuading anyone that you deserve a link, only that the mechanics should match the intent. Fixing an inbound 404 needs no one else’s cooperation at all; converting an unlinked mention needs only a small, warm ask. Compared with the effort of earning a genuinely new editorial link, the same hour spent on reclamation typically recovers more authority. Run it as a standing, periodic sweep, quarterly for most sites, rather than a one-off, because new 404s and new unlinked mentions accumulate continuously as your site changes and your brand gets referenced.
