Quick answer: Broken link building means finding dead links on relevant sites, then offering your content as the replacement. It works because you lead with the publisher’s problem rather than your request. Be realistic about the numbers: published success rates range from about 2% to 20%, and the spread is explained by fit. A generic pitch offering vaguely related content converts near the bottom of that range; a genuine one-to-one replacement for exactly what died converts near the top. Treat it as a steady supplementary campaign, not your main strategy.
This is the tactic everyone learns second, and it earns its place: the outreach is warm, the ask is helpful, and it scales. It is also routinely oversold. This guide covers what it actually returns and how to land at the good end of the range. It is part of our ecommerce link building guide, within our ecommerce SEO guide.
If you would rather have this run for your store, our ecommerce link building service builds editorial links to the category and product pages that actually earn, not just the homepage.
The numbers, honestly
The published figures contradict each other badly, so here is the spread rather than a flattering pick. Authority Hacker data puts broken link building at 2 to 5% from outreach to placed link. Blue Tree reports 8 to 15% on targeted campaigns, calling it the second-highest converting cold approach. Another 2026 compilation says generic campaigns run 1 to 2% but climb toward 20% when the replacement is a perfect one-to-one match for the dead resource.
Those are not really in conflict. They are measuring different levels of effort. The variable is match quality, which means the number you get is mostly under your control. That same data offers the practical lever: creating a purpose-built replacement rather than offering something you already had can raise success rates substantially.
The honest positioning: broken link building is used by a modest share of marketers and rated highest-ROI by very few. It is a supplementary campaign with the lowest cost per link of any tactic, not the engine of your program. Run it alongside reclamation and assets, not instead of them.
Where the dead links are
Some page types rot faster than others, and knowing which saves hours:
- Resource pages. They have the highest density of dead links of any page type, averaging around 7% broken, because they are lists of other people’s URLs that nobody maintains.
.eduand.govpages. These run higher than commercial sites, roughly 8 to 12%, because the content outlives whoever maintained it.- Competitor backlink profiles. Run a competitor through Ahrefs and look at broken backlinks: every site linking to their dead page is a prospect who has already shown they link to your niche. This overlaps neatly with competitor backlink replication.
- Old roundups and “further reading” lists. Same rot, same opportunity.
The process
- Find the dead link. Ahrefs Site Explorer’s broken backlinks report, or crawl a target site with Screaming Frog for 404 outbound links.
- Check what it used to be. Paste the dead URL into the Wayback Machine. You need to know what the page actually covered before you can offer a real replacement. Skipping this step is why most pitches fail.
- Find everyone linking to it. One dead page often has many linking sites. That is one piece of research and dozens of prospects.
- Match or build. Do you already have a genuine equivalent? If not, and the opportunity is big enough, build one. That is the difference between 2% and 20%.
- Pitch the problem, not the ask. Lead with their broken link.
Template
Subject: Broken link on [ARTICLE_TITLE]
Hi [NAME],
I was reading your piece on [TOPIC] and the link to [WHAT_IT_WAS] looks like it is returning a 404.
I published something covering the same ground that might work as a replacement: [YOUR_URL]. Either way, I thought you would want to know it was broken.
[YOUR NAME]
The last line is what makes it work. You are genuinely helping regardless of the outcome, and that tone is the reason this converts better than a cold ask.
The ecommerce catch
One caveat specific to stores. Your replacement has to be genuinely equivalent content, which means it is almost never a product page. Nobody’s dead link pointed at a shop. It pointed at a guide, a resource, a set of data. So this tactic works only if you have linkable assets or genuine category-as-guide pages to offer. If your site is only products, there is nothing to swap in, which is another reason the asset library comes first.
Common mistakes
- Offering content that is not a real match. The single biggest cause of the 2% end of the range.
- Skipping the Wayback check. If you do not know what died, you cannot replace it.
- Pitching a product page. The dead link was not a shop. Yours will not be either.
- Treating it as the main strategy. Low cost per link, low ceiling. It supplements; it does not carry.
- Only checking one linking site. One dead URL usually has many. Do the research once, pitch everyone.
- Leading with the ask. Lead with their broken link. That is the entire reason it converts.
Frequently asked questions
What is broken link building? It is finding dead links on relevant websites, then contacting the site owner to point out the broken link and offer your content as a replacement. It converts better than most cold outreach because you lead with a problem the publisher genuinely wants fixed rather than with a request for a favor.
What is the success rate of broken link building? Published figures range from about 2% to 20%, and the spread reflects match quality rather than measurement error. Generic pitches offering loosely related content sit at the bottom; a genuine one-to-one replacement for exactly what died sits near the top. Building a purpose-made replacement raises the rate substantially.
How do you find broken links for link building? Use Ahrefs Site Explorer’s broken backlinks report on competitors and relevant sites, or crawl targets with Screaming Frog for 404s. Focus on page types that rot fastest: resource pages average around 7% dead links, and .edu and .gov pages run roughly 8 to 12%. Then check the Wayback Machine to see what the page covered.
Does broken link building work for ecommerce stores? Only if you have content to offer. Dead links almost never pointed at product pages, so your replacement must be a genuine guide, resource, or data asset. Stores with only product and category pages have nothing to swap in, which is why building linkable assets comes first.
Broken link building is honest work: you find something broken, you tell someone, and sometimes they thank you with a link. It will not carry your program, and the guides promising otherwise are selling something. But it has the lowest cost per link of any tactic, the outreach is genuinely welcome, and the difference between the bad numbers and the good ones is simply whether you bothered to offer a real replacement.
This tactic needs two things: content worth swapping in, and someone doing the prospect research and manual outreach. Our ecommerce link building service covers the research and outreach across editorial targets, and our ecommerce SEO blog writing builds the guides and assets that make a replacement possible, since a product page will not do.
