Can a Backlink Checker Tool Identify Lost or Broken Links?

Yes. A backlink checker tool can identify lost backlinks, broken links and links whose destinations have changed by regularly monitoring referring pages, link attributes, HTTP status codes and target URLs. It can show whether a backlink is still present, whether the referring page or target page returns an error, and whether a link now leads through a redirect or to a different destination. This makes it possible to investigate changes and take corrective action before valuable links stop contributing to your SEO performance.

A lost backlink is a link that previously pointed to your website but can no longer be found on the referring page. The page may have been edited, removed or replaced, or the publisher may have deleted the link. A backlink checker normally identifies this by comparing current crawls with earlier records. The result should be reviewed rather than treated as conclusive immediately, because a temporary crawling issue, server outage or page update can make an active link appear to be missing.

A broken backlink is still present on the referring page but does not provide a usable route to your website. This can happen when the linked URL returns a client or server error, the page has been deleted, the domain has expired, or the URL contains a typing error. Some tools also flag links to pages that return a soft error, where the server technically responds successfully but displays a missing-page message. These cases are important because the referring page may still be able to send visitors, authority and context if the destination is restored or corrected.

Backlink monitoring can also reveal links affected by redirects. A redirect is not automatically a problem, particularly when it is a deliberate permanent redirect to a relevant replacement page. However, a chain of redirects, a temporary redirect, an irrelevant destination or a redirect to an error page may reduce the value and usability of the link. Reviewing the original URL, the redirect path and the final destination helps distinguish a healthy redirect from one that requires attention.

When assessing a flagged backlink, review the following information:

• Link status: whether the link is active, missing, broken, redirected or temporarily unavailable.
• Referring page: whether the source page is live, relevant and still accessible to users and search engines.
• Target URL: whether the linked page is the intended destination and returns the expected content.
• HTTP response: whether the destination returns a successful response, an error or a redirect.
• Link attributes: whether the link is marked as sponsored, user-generated or otherwise qualified.
• Historical status: whether the change is recent, recurring or part of a longer-term decline in link coverage.

A practical recovery process starts by confirming the issue manually. Open the referring page, check that it is accessible and search its source or visible content for your domain or target URL. Then open the destination and confirm its response and content. This helps rule out temporary technical problems or a reporting delay in the tool.

If the referring page is live but the backlink has been removed, contact the site owner with a specific correction request. Explain which page previously contained the link and suggest the most relevant destination on your website. Keep the request factual and make sure the proposed page genuinely supports the surrounding content. If the destination is broken but the referring page still links to it, restore the original page where appropriate or create a closely matching replacement and redirect the old URL to it.

Where a page has been permanently moved, implement a relevant redirect from the old URL to the new one and update internal references to use the final destination. Avoid redirecting unrelated URLs to the homepage simply to preserve a backlink. A redirect should help users reach substantially similar content; otherwise, it may provide little practical value and can create a poor experience for visitors.

Not every lost or broken backlink requires recovery. Prioritise links from relevant, authoritative pages that attract referral visits, support important commercial or informational content, or contribute to a broader pattern of coverage for a topic. A single low-quality or irrelevant link is usually less important than a broken link from a page that is closely aligned with your audience and subject matter. You should also investigate several losses occurring around the same time, as they may indicate a website migration, a discontinued publication or a technical issue affecting your own domain.

Backlink checker data has limitations. Crawlers may not access every page, JavaScript-generated links may not be detected consistently, and a source page can change between crawls. A link that is temporarily unavailable may also be marked as lost after a failed request. For this reason, use repeated observations and manual checks before removing pages, changing redirects or contacting publishers. Server logs, crawl reports and website analytics can provide additional evidence, particularly when you need to establish whether users are still reaching the destination.

For ongoing protection, schedule regular backlink checks and compare new findings with historical data. Pay particular attention after website migrations, URL changes, content pruning, domain changes or major technical updates. Maintaining a record of important referring pages, their linked destinations and any agreed corrections makes it easier to identify recurring problems and recover valuable links efficiently.
