Broken link building is a white-hat link building tactic that turns other people's mistakes into opportunities for you. The idea is simple: you find dead links on relevant websites, then reach out to suggest your own content as a replacement. It works because you are genuinely helping the site owner fix a problem — and in return, you earn a quality, relevant backlink.

Why broken link building works

Most link building asks a webmaster to do you a favor. Broken link building flips that: you are doing them a favor by pointing out a broken link that hurts their user experience and credibility. That makes your outreach far more welcome, and your success rate much higher than a cold 'please link to me' request. The links you earn are also contextual and relevant, which is exactly the kind Google values.

The step-by-step process

  • Find relevant pages. Look for resource pages, link roundups and articles in your niche that are likely to contain outbound links.
  • Scan for dead links. Check those pages for broken outbound links with the Broken Link Checker.
  • Create or match content. Make sure you have a page that genuinely fits as a replacement for the dead resource.
  • Reach out. Email the site owner, point out the broken link helpfully, and suggest your content as a replacement.

Finding the best opportunities

The highest-value targets are pages that already link out to several sites like yours. Find domains that link to multiple competitors with the Link Intersect / Backlink Gap — these sites clearly link to content in your space and are prime candidates. Study a competitor's overall footprint with the Competitor / Site Explorer to understand the kinds of resources that earn links in your niche. This research focuses your effort on outreach most likely to succeed.

Writing outreach that works

Your email should be short, genuine and helpful. Lead with the value to them — you found a broken link on their page — then mention your resource as a possible replacement without being pushy. Personalize it, keep it concise, and make it easy for them to say yes. Avoid templated, mass-mailed messages; webmasters can spot them instantly and ignore them.

Frequently asked questions

Is broken link building worth the effort?

Yes, especially for smaller sites. It is more labor-intensive than some tactics, but the links are relevant and earned ethically, and the success rate is higher than generic outreach because you are providing real value. A handful of quality links from this method can meaningfully move rankings.

What content makes a good replacement?

Your replacement should closely match what the dead link originally offered — the same topic, format and depth, or better. If the broken link pointed to a guide on a subject, offer your own thorough guide on that subject. The closer the fit, the more likely the webmaster is to use your link.

Conclusion

Broken link building is one of the most beginner-friendly, ethical link building tactics available. Find dead links on relevant pages, create a fitting replacement, and reach out helpfully. Use the Broken Link Checker to find opportunities and the Link Intersect / Backlink Gap to target the best prospects, and combine it with the broader strategies in our link building guide.

Like all link building, broken link building rewards patience and volume. Not every email will get a reply, and not every reply will result in a link — a modest success rate is normal. The key is to keep a steady pipeline: regularly find new resource pages, check them for dead links, and send genuine, personalized outreach. Over weeks and months, those individual wins accumulate into a backlink profile that competitors relying on shortcuts simply cannot match.
