Separate replacement research from repairing your own site
Broken link building starts with a reference on another publisher's page that may no longer serve its reader. You investigate the original resource and, when useful, suggest a suitable replacement. Repairing a missing page on your own domain is a different task: you may control restoration or a relevant redirect. You cannot redirect a publisher's link by changing a page you do not own.
Keep three addresses separate: the referring page, the reported broken destination and your proposed resource. The explorer above uses seven fictional cases to show how those records interact. Its dates, responses and resources are teaching material, not a discovered inventory of available links or evidence of a live crawl.
Find references with a concrete reader purpose
Start with a relevant resource page, an industry guide or a research article. Record the referring URL, the exact destination and the sentence surrounding the reference. A tool export can help discover candidates, but a row saying broken does not explain why the publisher used that source or whether the link still exists.
In the insulation example, the reference supplies a cost-comparison worksheet. That role is more specific than the general topic of home improvement. Group repeated findings by the same referring-page and destination pair while preserving their observation dates. Several rows from one page are not several independent publishers or several outreach opportunities.
Recheck both ends and retain the timeline
Review the current source page as well as the reported destination. A source may remove its reference while an old export still contains it. A previously failing destination may recover, move or restrict access. Keep the earlier observation instead of overwriting it, then identify which later evidence supports the next action.
The explorer always uses its later record for the decision, including while the older report is highlighted. A later 200 with restored content closes the missing-resource claim; a functioning redirect requires inspecting the moved material. A 403, rate limit, server error or failed connection does not establish deletion. These are research decisions for a human review, not a simulation of Google's indexing. An HTTP response alone does not prove indexing or usefulness.
Recover the original task from context
Read the source paragraph, nearby headings, anchor and any available description of the old material. Existing records or an archived version may help establish its purpose, but an archive is not permission to copy somebody else's work. Record what you actually established and which details remain unknown.
The final example deliberately has only a vague “more information” reference. A keyword in its address cannot establish whether the original was a calculator, a study or a product page. Even a convincing new resource cannot resolve missing evidence about the original task. Keep the decision open until the context is adequate.
Compare the replacement at the level of the task
The worksheet example needs a usable comparison with assumptions, not simply another page mentioning insulation. The historical research example needs data from the cited period with compatible definitions and methodology. A sales page serves a different purpose. A modern overview may be useful in its own right while still being a poor substitute for a historical dataset.
Select each of the three replacement cards in the explorer. The persistent worksheet case and the dataset case require different resources. The decision is based on the authored task, not a domain score or a count of matching words. For a real suggestion, inspect your resource's availability, accuracy, format, audience and limitations, and explain any meaningful differences from the original.
Use the correct Ahrefs report for the direction of the link
Ahrefs documents Site Explorer's Outgoing links → Broken links report for references leaving a chosen domain or URL. Its Broken backlinks report instead lists referring pages pointing to 404 destinations within the chosen target. Choose the direction that matches your investigation; your own broken incoming links are primarily a repair problem.
In an outgoing-links export, retain referring-page and destination check dates, labeled RP check and DP check in the documentation. Ahrefs describes these records as dependent on its crawler's last checks. Its documentation points to Site Audit for on-demand external-link checks, with that check enabled. These are documentation-based navigation notes, not a test of an authenticated Ahrefs account, its current coverage, plan limits or a live opportunity list. Revisit each candidate yourself before making a current claim.
Prepare a specific, optional publisher suggestion
A qualified handoff includes the source page, old address, check date and method, original reader task, proposed replacement and differences. Establish the publication's appropriate contact route and review the actual correspondence history. A stop request or unsuitable audience ends that outreach path regardless of how attractive the missing destination looks.
Describe the observation accurately: what you checked and when, rather than claiming the whole website is broken. Explain why your resource helps and disclose your connection to it. The publisher decides whether to update the page, choose a different source or decline. Google's link-spam policies still apply to the underlying arrangement; describing a paid or conditional placement as a helpful correction does not change that arrangement. This guide does not send the request.
Keep investigation, correspondence and publication separate
Download a case to inspect both observations and the selected replacement reasoning. Use the blank review sheet for your own work; it contains no invented checks or prefilled outcomes. The existing source-and-destination checker can support a real observation when you choose to run it, and the outreach guide helps qualify a publisher before drafting.
A prepared review is not a sent message, an acceptance is not a live link, and a publication is not proof of ranking gains. If a reference appears, save the actual URL and inspect its destination and attributes. Record the outcome even when a candidate is closed: recovered resources, removed references and inadequate context are useful research results, not failures to hide in a success count.
