Free Lost Backlinks Tracker

The Lost Backlinks Tracker compares two backlink lists (previous vs. current snapshot) to identify which links were lost, which were gained, and which were retained — plus churn rate and retention rate stats.

Churn rate is the share of your previous backlinks that disappeared, calculated as lost links divided by your previous total, multiplied by 100. If 8 of 80 links from your earlier snapshot are missing from the current one, that is a 10% churn rate. As a rule of thumb, a stable profile runs under 10% monthly churn, 10 to 20% is moderate and worth watching, and anything above 20% signals trouble that calls for immediate reclamation. The figure matters because losing links erodes the authority that helped pages rank, and high churn often points to broken redirects after a migration or editors removing references. The Lost Backlinks Tracker computes churn for you the moment you compare two lists, alongside retention rate and net change, so you can judge profile stability at a glance instead of counting links by hand.

A lost backlink is a link that existed in an earlier snapshot but no longer appears in your current data, usually because the linking page was deleted, the editor removed your reference, or a competitor's link replaced yours. A broken backlink still exists on the linking page but points to a URL that now returns a 404 or dead destination, often after you moved or deleted the target page. The distinction matters for recovery: a truly lost link needs outreach to the site owner, while a broken one is frequently fixable on your own side with a 301 redirect from the old URL to the new one. This tool surfaces lost links by diffing two lists you supply; once you have that list, check each one to see whether the page is gone entirely or simply pointing at a broken URL you can redirect.

It happens when the same link is written slightly differently across two exports, since a naive text match treats them as separate URLs. For example, one tool might list https://www.example.com/page/ while another lists example.com/page, and a plain comparison would flag the first as lost and the second as gained even though they are the same link. To prevent this, the Lost Backlinks Tracker normalizes every URL before comparing: it lowercases the address, strips a leading www., removes a trailing slash, and adds a scheme if one is missing. After normalization both versions resolve to the same canonical form and are correctly counted as one retained link. This is why exports from different sources still diff cleanly. If you want a specific match treated differently, edit the URLs in your input lists before clicking Compare so they reflect the exact form you intend.

For most sites a monthly comparison strikes the right balance, catching churn early without reacting to normal day-to-day fluctuation in crawl data. Export your backlinks on a fixed schedule, label the older file as your previous snapshot and the newer one as current, then diff them to see what changed over the period. Run an extra comparison after major events that disrupt links, such as a site migration, a replatform, or a large content restructure, since those are when redirects break and references get stranded on dead URLs. Faster-moving sites earning links daily may prefer weekly checks, while smaller sites can space comparisons further apart. Whatever cadence you pick, consistency matters more than frequency because clean period-over-period diffs reveal trends. Paste your two dated snapshots into the tracker to see your churn rate and full list of reclaim targets for that window.

Many lost links are recoverable, especially when the linking page is still live and only your link was removed or redirected. Start by visiting each lost URL: if the page returns a 404, the webmaster likely deleted it, so a polite note asking whether they can restore or redirect it is worth sending. If the page still exists but your link is gone, check whether you moved or significantly changed the target content, then offer the corrected URL. Watch for cases where an editor swapped your link for a competitor's, which usually means you need a stronger pitch on why your resource is better. Finally, confirm that old URLs on your own site carry proper 301 redirects, since many losses are just missing redirects after a restructure. Export the lost-links list from this tool and work through it as a focused reclamation campaign.
