What is a lost backlink?

A lost backlink is a link that used to point to your site and no longer does: the page was deleted, the link removed, the site closed or your URL changed. Every site loses links over time. Directory listings are lost when directories die, prune old listings or require a badge you removed.

Cause Example
Page deleted A blog removes old posts
Link removed An editor updates an article
Site gone A dead directory closes
Your URL changed You renamed a page without a redirect
Condition broken You removed a required badge
Became nofollow A directory changed its link policy

Research on link rot finds large shares of links on the web break within a few years, so some loss is normal.

Finding them

SEO tools list lost links with dates. Your submission tracker helps for directories: recheck listing URLs every few months. Search Console's Links report shows current links only, so compare exports over time.

Which to reclaim

Reclaim strong, relevant links: fix your redirects, update listings, reply to the directory. Let go of links from dead or spam sites. See link reclamation.

Example

After a site redesign, a startup loses 90 backlinks overnight because its blog URLs changed. Adding 301 redirects from old to new URLs restores them within weeks.

FAQ

Is losing backlinks bad?

Losing strong ones can hurt rankings. Losing weak or spam links doesn't matter.

How do I get a lost link back?

Fix the cause: redirect your old URL, update the listing, or ask the site owner.

Why did my directory listing disappear?

The directory may have closed, pruned old listings, or removed you because a badge or condition was no longer met.
