How link reclamation works
Every link pointing at your site was earned once. Some of them stop working, and reclamation is the routine of finding those and putting them back to use. It is the cheapest link work available, because the persuasion is already done.
Lost links come in a few recognisable shapes. A link points at a URL you deleted or renamed, so visitors land on a 404. A redesign or a migration changed your URL structure and nobody mapped the old addresses. A publisher rewrote an article and dropped the reference. An image you produced is used on another site with no credit. A profile or listing was rebuilt and the links inside it were not carried over.
Each shape has its own fix. Broken destinations are yours to solve with a 301 redirect to the closest equivalent page, and no email is needed. Removed references and uncredited images need a polite message. Nothing here requires a new relationship.
Why it matters
A link that returns an error passes nothing on and sends visitors to a dead end, so the loss is both technical and commercial. Recovering it takes minutes, while earning a comparable new link takes weeks of pitching.
It matters most immediately after a website migration or redesign, which is when the largest number of links break at once and when the resulting traffic drop is usually blamed on an algorithm rather than on the redirect map. Checking the links report before and after a launch turns a mystery into a task list.
Where link reclamation goes wrong
Redirecting everything to the homepage is the classic mistake. A redirect only makes sense to a page that answers the same question; sending a reader who wanted a discontinued product guide to a homepage helps nobody, and search engines may treat the redirect as the soft error it effectively is.
The second is doing it once. Links decay continuously as sites are rebuilt and articles are pruned, so a one-off recovery project leaves a slow leak behind it. The third is assuming lost links explain a ranking drop before checking. Losing links is common, and it is only one of several possible causes.
How to act on it
Make it a scheduled review rather than a project. In Search Console, look at pages returning errors that still have inbound links, and check the links report for referring pages that no longer resolve. Backlink tools such as Ahrefs and Semrush both report lost and broken inbound links, which catches the cases Search Console will not show you.
Fix everything you can from your own side first, then write to publishers about genuine removals, keeping the note short and factual. Where an image or a piece of research is used without credit, ask for attribution rather than demanding a link. Treat the whole routine as maintenance within your link building work, and run it whenever the site structure changes.
