Broken Link Building: 5 Proven Steps to Earn Real Backlinks

Hey! If you have ever clicked an old link on a trusted site and landed on a dead page, you have already met the opportunity this guide is about. Most people just hit the back button. A few people turn that dead page into a backlink.

Picture a resource page that has been linked to from dozens of sites for years, except the page itself went offline a while back and nobody ever noticed. Every one of those old links is now pointing at nothing. Broken link building is the practice of finding pages exactly like that one, building something better in their place, and asking the sites that linked to the original to send that traffic your way instead.

Broken link building is a link acquisition tactic built around a simple fact: pages die constantly, but the links pointing at them usually do not get cleaned up. Ahrefs describes the process as finding a dead page with backlinks, creating a similar or better page of your own, then asking the sites linking to the dead page to swap that link for yours.

It works in three parts. First you find a page that now returns a 404 or some other error but still has real sites linking to it. Second you publish a page covering the same ground, ideally better than what was lost. Third you email the webmasters who linked to the dead page and point out that their link is broken, with your page offered as the fix.

This is different from most link building tactics because you are not asking for a favor out of nowhere. You are flagging a genuine problem on someone else's site and handing them a ready made solution, which is exactly why this approach keeps showing up in SEO guides more than a decade after it was first popularized.

A dead link is a small but real problem for whoever owns the page it sits on. It sends visitors to an error page, it wastes the link equity that page once passed along, and on a resource list it makes the whole page look unmaintained.

Broken link building succeeds because you are not interrupting someone's day with an unrelated request. You are telling them something they would want to know anyway and offering the easiest possible fix, a single find and replace in their own content management system.

That is also why this tactic reads as a genuinely white hat approach rather than a trick. Semrush frames it plainly: broken link building is the process of finding dead links on other sites and convincing the people who run those sites to replace them with working links to your own content.

Everything starts with finding a dead page that other sites still link to. A handful of real tools make this practical rather than a guessing game.

The most direct route is Ahrefs Site Explorer. Drop in a competitor's domain or a relevant resource page, filter outgoing links by status code, and you get a list of every link on that page or domain that now returns a 404 or similar error, along with how many sites link to each one. Respona's own walkthrough of the process notes that defunct websites with a large backlink profile are especially good targets, since a single abandoned domain can surface a dozen broken pages at once, each with its own set of linking sites.

For checking a single page rather than a whole domain, the free Check My Links browser extension does the job in seconds. It scans every link on the page you are viewing, color coding working links green and broken ones red, with the specific error code shown next to each one. The project is open source and actively maintained on GitHub, so it is worth running directly against resource pages and link roundups in your niche.

Tool	What It Finds	Best Use
Ahrefs Broken Link Checker	Dead outgoing links on any domain, plus how many sites link to each one	Scanning competitors and whole resource hubs at once
Check My Links	Every broken link on the single page open in your browser	Quickly auditing one resource page or article
Wayback Machine	Archived snapshots of what a dead page used to contain	Matching your replacement page to the original content

Not every dead page is worth chasing. A site that only has a handful of weak, spammy links pointing to it is not going to move the needle, so check the authority and relevance of the linking sites before you invest time in a replacement page.

Equally important is understanding what the dead page actually covered, since your replacement needs to match that intent closely, not just the general topic. This is where the Wayback Machine earns its place in every broken link building workflow. Pulling up an archived snapshot shows you the original headings, the data it cited, and the exact angle it took, so your new page can genuinely replace it rather than loosely resemble it.

Checking the anchor text the dead link used on each referring page is worth the extra minute too. If a dozen sites all linked using the same phrase, that tells you exactly what those readers expected to find when they clicked, and your pitch should speak to that expectation directly.

This step is where most broken link building campaigns quietly fail before a single email is sent. If your replacement page is thinner, older, or less useful than what disappeared, nobody has a good reason to link to it.

Semrush's own research into why site owners respond to this kind of pitch is blunt about it: they are more likely to update a link when the new page is contextually relevant and genuinely high quality, and less likely to respond if a better alternative already exists elsewhere or the replacement looks outdated.

Use what you pulled from the archived snapshot as a floor, not a ceiling. Cover everything the original page did, then add what it was missing, a clearer structure, more current data, a simpler explanation, or examples the old page never had.

With a finished replacement page ready, the next step is finding an actual person to email, not a generic contact form. An editor, a content manager, or whoever wrote the page with the broken link is a far better recipient than a general info address.

Your email needs three things to land: the exact broken URL you found, a one line note on what your page covers, and a link to it. Mention the specific page their link sits on, since that single detail proves you actually looked at their site rather than mass mailing a template.

Response rates for outreach like this are modest by nature, which is worth knowing going in. An analysis of 12 million outreach emails by Backlinko and Pitchbox found that only 8.5 percent of outreach emails receive any reply at all, and the same study found that outreach specifically about link building, guest posts, and resource roundups performed above that overall average.

A quiet inbox does not always mean no. The same large scale outreach study found that sending a single polite follow up message increased reply rates by roughly 66 percent, so one short nudge a week later is worth the thirty seconds it takes to write.

Most broken link building pitches that get ignored fail for the same handful of reasons, and they are easy to spot once you know what to look for.

Once a handful of pitches start landing, keep a simple log of which prospects responded, which niches reply most often, and which email framing worked best. This approach rewards patience far more than volume, a dozen genuinely relevant, well matched placements from one campaign is a realistic, solid outcome.

Treat broken link building as one tool in a wider kit rather than your only source of links. Running a backlink profile analysis on a few competitors first often surfaces several dead pages worth pursuing before you even start building a replacement.
