Broken Link Building: A Step-by-Step Guide

Broken link building is a white-hat tactic where you find a dead (404) link on someone else's page, then offer your own relevant page as a replacement. It works because you are doing the site owner a favor — nobody wants broken links on their site — and giving them an easy, specific fix. When your page is a genuinely good substitute for what used to be there, the swap is a win for both sides.

Why it works

Most outreach fails because it asks for a favor and offers nothing. Broken link building flips that: you lead with a problem the owner already has and hand them the solution. It is also naturally relevant — you are only pitching pages that fit the exact context where a link already existed, so the resulting link is on-topic by design.

The step-by-step process

1. Find relevant pages: look at resource pages, roundups, and articles in your niche that are likely to link out a lot ('best tools', 'further reading', link lists).
2. Scan for dead links: use a broken-link checker or a browser extension to spot 404s on those pages.
3. Check what the dead page used to be: look it up in the Wayback Machine so you understand what content it offered.
4. Match or create a replacement: point to your existing page that covers the same ground — or write one if the fit is close but not exact.
5. Find the right contact: the author, editor, or site owner, via the page byline or the site's contact page.
6. Send a short, specific email: name the exact broken link, why it matters, and your replacement — make saying yes effortless.

An outreach template that respects their time

Keep it under 120 words. Something like: 'Hi [name] — I was reading your guide on [topic] and noticed the link to [resource] returns a 404. I recently published [your page], which covers the same ground, in case it's a useful replacement. Either way, thought you'd want to know about the dead link.' You are helping first and pitching second, which is exactly why it converts better than a cold 'please link to me.'

Realistic expectations

Response rates are modest — a few percent to low double digits — so this is a numbers game built on a real value exchange. Send a batch of well-researched, genuinely helpful emails, expect most to go unanswered, and treat the links you do earn as the durable, relevant kind that keeps working for years.
