Most link building tactics are some variation of asking a stranger for a favour. Broken link building is different. It works because it offers the linking site something genuinely valuable: a fix for a problem they did not know they had. That is why it remains one of the most effective and lowest-risk link tactics in 2026, and why it is still underused.
How broken link building works
The web is full of broken links. Sites go down, pages get deleted, companies fold, URLs change. Any given authoritative site has links pointing to resources that no longer exist. Broken link building is the process of finding those broken links on relevant sites, having a resource that could replace them, and letting the site owner know.
The pitch is genuinely helpful: “You have a broken link on this page pointing to a resource that no longer exists. Here is a working alternative that serves the same purpose.” The site owner gets a fixed page. You get a link. Nobody is doing anyone a favour, both sides win.
Step 1: Find the broken links
Start with resource pages and link roundups in your industry, pages that exist specifically to link out to useful resources. These accumulate broken links over time. Tools like Ahrefs and Semrush can scan a page or a whole site for broken outbound links. Browser extensions can check links on the fly while browsing relevant pages.
Another angle: find a competitor or a defunct resource that used to have many backlinks, then look at who links to it. Every one of those links is now broken and is a broken link building opportunity.
Step 2: Have the replacement ready
The tactic only works if you have a resource that genuinely replaces what was lost. If the broken link pointed to a “guide to small business SEO” and you have a comprehensive guide to small business SEO, that is a match. If you have nothing relevant, the outreach has no foundation.
Sometimes the right move is to create the replacement resource specifically. If you find twenty sites linking to a now-dead authoritative resource on a topic, building the definitive modern version of that resource gives you twenty warm outreach targets.
Step 3: The outreach
The outreach email is short and genuinely helpful. Identify the broken link specifically, mention the page it is on, briefly note that the destination is dead, and offer your resource as a replacement without being pushy about it. The tone is “thought you would want to know”, not “please link to me”.
Response rates for broken link building are higher than cold link outreach because the email leads with value. Even when the site owner does not use your resource, they often appreciate the heads-up, which keeps the relationship warm.
Why it is low-risk
Every link earned through broken link building is editorial. The site owner chose to add it, on a real page, because it genuinely improved that page. There is no payment, no scheme, no pattern Google would flag. It is exactly the kind of link Google wants to see, earned the way Google wants it earned.
The honest limitations
Broken link building is slow and the hit rate is modest. You might check fifty pages to find ten good broken links, send ten emails, and earn two or three links. It does not scale infinitely. But the links it does produce are high quality and permanent, and the process also surfaces relationship opportunities and content gaps along the way.
It works best as one tactic within a broader link building program, alongside digital PR and editorial outreach, rather than as a standalone strategy.
Where it fits
For a business that has good content already, broken link building is a way to get that content in front of site owners who have a reason to link to it. The content exists, the broken links exist, the tactic just connects them.
