Broken Link Building: Winning Backlinks via Broken Links

Broken Link Building in one sentence

Broken link building (also dead link building) is a link building method in which you find broken links on other websites, point them out to the operator, and propose your own thematically fitting content as a replacement. The appeal lies in the double benefit: you help the webmaster fix an error on their page – and gain a high-quality backlink in the process. This makes broken link building one of the more advanced techniques in link building.

The basic idea: webmasters do not want to offer their visitors faulty links. Anyone who supplies a working alternative provides real added value – and thereby increases the willingness to link.

Does Broken Link Building Still Work Today?

Opinions differ. Some consider the method less effective than others, while others continue to achieve success. The truth lies in between and depends heavily on the execution. Link building is generally demanding – broken link building is no exception. It requires patience, the right tools, and a well-thought-out approach. The decisive advantage remains, though: you offer a concrete benefit first, instead of merely asking for a link.

The Process in Four Steps

A successful campaign can be divided into four phases: find broken pages with backlinks, evaluate the backlinks, provide replacement content, and finally do outreach.

Step 1: Find Broken Pages with Backlinks

Without specialized tools, it is barely possible to find broken pages with noteworthy backlinks. Tools like Ahrefs, Semrush, or Moz Link Explorer are indispensable here. These methods have proven themselves:

• Analyze competitors' broken pages: Enter a competitor's domain into the "Site Explorer", navigate to the "Best by Links" report, filter by the status code 404 not found and sort by the number of referring domains. Background on status codes is under HTTP status codes.
• Search by topic: The Ahrefs Content Explorer searches the entire web. Enter a broad keyword, set the mode to "In title", filter by "Only broken pages" and optionally by a minimum number of referring domains.
• Check broken outbound links: Almost every website links to external resources, some of which lead nowhere. The "Broken links" report under "Outgoing links" lists them.
• Search resource pages: Find link collections with search operators like KEYWORD intitle:resources inurl:links.html and check them with browser extensions like Check My Links.
• The Wikipedia "dead link" technique: Search with site:wikipedia.org "KEYWORD" intext:"dead link" for articles with sources marked as dead. Do not replace the link directly on Wikipedia (mostly nofollow there), but check which other pages also link to the dead source.

Step 2: Evaluate Link Potential (Vetting)

It is tempting to create replacement content right away – but check the quality first. Not every backlink is valuable.

Check the quality of the backlinks: Enter the URL of the broken page into a backlink analysis tool and filter out low-quality links – for example show only dofollow links, exclude domains with a very low Domain Rating, and remove sources without traffic. How to systematically evaluate a link profile is shown by the backlink analysis.

Understand the reasons for the link: Why did others link to the dead page? There are two types:

• General links: The page is recommended as a whole, without a recognizable reason (e.g. anchor text "click here").
• Deep links: The page is linked because of a specific aspect – a statistic, definition, or guide. The reason is clear from the context (e.g. "according to this study …").

Pay particular attention to deep links and note which information led to the link. The Wayback Machine (archive.org) helps you view the original content of the dead page.

Step 3: Provide Replacement Content

With the knowledge from step 2, you provide a fitting replacement. Either you use existing content that fills the gap well – or you create new content. Good replacement content should resemble the purpose of the original page, cover the "linkable points" of the deep links, and improve on the original: more up-to-date, more understandable, more visually appealing, or supplemented by additional resources. The goal is a replacement that is at least as good, ideally better. Use the Wayback Machine as a template, but avoid direct copies (plagiarism).

Step 4: Carry Out Outreach

Now you contact the webmasters who link to the dead page. An email to a general info@ address rarely leads to success – find the responsible person via "About us" pages or author profiles.

The following principles apply to the message: point out the specific broken link in a friendly way, write personally instead of generically, and offer your content as a clear alternative. Briefly explain why it is a good replacement – same topic, more up-to-date information, additional template. If you know why the link was originally set, address that specifically. Keep the message short; a subject line like "Broken link on your page [name]" helps. And stay friendly rather than demanding: a gentle suggestion goes over better than a direct request for a link. We go deeper into the general outreach principles under Outreach for Link Building.

Not everyone will reply – that is normal. A friendly follow-up after some time is fine, without becoming pushy. Do not waste time on websites that have not been maintained for years.

Conclusion

Broken link building is a proven tactic that, applied correctly, can still deliver high-quality backlinks. The key lies in offering real added value by helping webmasters improve their pages. This requires careful research, an honest assessment of the link potential, relevant replacement content, and a personalized, helpful approach. The process is time-consuming – but thanks to the clear value proposition, broken link building belongs in every comprehensive link building strategy.
