Broken Link Building

Broken link building is finding dead links on other people's websites and persuading the site owner to replace them with a link to your equivalent (usually better) resource. It's fully white-hat — you're fixing someone's site for them — but anyone selling it as easy is lying: the yield per hour is low, and most of your emails will be ignored.

The honest pitch: why it works, and why it underdelivers

The logic is sound. The web rots — pages get deleted, domains expire, URLs change — and every dead outbound link is a small embarrassment for the site that hosts it. You arrive with a genuine favor ("this link on your resources page is dead") and a self-interested suggestion ("my guide covers the same ground"). Value for both sides, no guidelines bent.

The catch is the funnel. Most dead pages worth replacing have already been pitched by everyone else running the same Ahrefs report. Many linking pages are themselves abandoned — nobody is home to answer your email. And webmasters who do respond often just delete the dead link rather than swap in yours. So a hundred prospects become a few dozen deliverable emails become a handful of links. The links you do land are real editorial links on aged, relevant pages — genuinely good ones — but you earn them one at a time, and the hourly math only works if your prospecting is sharp.

A real example

Say you run a site about home coffee roasting. You find that a popular "coffee science" resource page at a culinary school links to a roast-profile explainer that died when a hobbyist's blog lapsed in 2021. You check the dead URL in the Wayback Machine, confirm your own roast-profile guide covers everything it did (and more), and email the page's maintainer: here's the dead link, here's the archived version so you can verify, here's my replacement if it fits. That specificity — proving you actually looked — is what separates a swap from a delete.

The pipeline: stages, tools, and what actually converts

How to run it, step by step

1. Pick a topic where you already have (or will build) a genuinely strong page. Everything downstream depends on the replacement being an upgrade.
2. In Ahrefs, open a competitor or big niche site → Best by links → filter 404. Every dead page with referring domains is a prospect list in one click.
3. Export the referring pages for each dead URL and cut the junk: scrapers, forums, dead blogs, non-English mismatches.
4. Check the dead page in the Wayback Machine and make sure your page covers what linkers were originally citing.
5. Find a named contact with Hunter.io or the site's about page.
6. Send a three-sentence email: where the broken link is, proof it's dead, your replacement. No flattery paragraphs, no "I hope this email finds you well."
7. Follow up once, then let it go. Track placements in a simple sheet against hours spent, so you know your real cost per link.

Common mistakes (and fixes)

• Pitching a loosely related page as a "replacement." Webmasters check, and mismatches get deleted, not swapped. Fix: reconstruct the dead page first and only pitch true substitutes.
• Targeting dead pages nobody links to. A 404 with two referring domains isn't a campaign. Fix: qualify by live referring domains before writing anything.
• Mass templated blasts. That's how this tactic became outreach spam in the first place, and recipients can smell it. Fix: fewer prospects, visibly hand-checked emails.
• Counting the wrong outcome as success. "Thanks, fixed!" (link removed) helps their site, not yours. Fix: make the swap effortless — exact URL to remove, exact URL to add.
• Running it as your only tactic. The yield is too thin to carry a program alone. Fix: treat it as one channel in a broader link building mix.

FAQ

Is broken link building still worth doing?

Yes, in niches with aging resource pages (education, health, government-adjacent, hobbies) and if you value link quality over volume. In fast-moving commercial niches the prospect pool is thinner and more picked-over, and your hours may return more via digital PR.

What response rate should I expect?

Plan for most emails to get no reply at all, and for only a fraction of replies to become links. If your placement rate on cold outreach reaches the high single digits, your prospecting and targeting are above average — don't let a vendor promise you otherwise.

Do I need paid tools?

Realistically yes for prospecting at any scale — Ahrefs or Semrush for dead-page discovery is the engine. The free tier: Check My Links for spot-checking resource pages, the Wayback Machine for reconstruction, and manual contact-finding.

Is broken link building white-hat?

Completely. You're reporting a genuine defect and offering an editorial replacement the site owner freely chooses. There's no payment, no scheme, no footprint — which is exactly why the links it produces hold their value. The full workflow lives in our step-by-step broken link building tactic.

Should I write new content for a campaign or use existing pages?

Start from dead pages with the most referring domains, then decide: if an existing page truly substitutes, pitch it today; if not, and the dead page has enough linkers to justify it, build the replacement — the prioritization logic is covered in our broken link building strategy article.
