Broken Link Building (the cleanest white-hat move)
Find dead links on relevant authority sites, suggest your content as the replacement. Wins because everyone — site owner, your readers, the internet — comes out better.
Broken link building (BLB) is the cleanest white-hat tactic in SEO because every party benefits: the site owner gets their content fixed, you get a high-relevance backlink, and the reader gets a working link instead of a 404. Conversion rates on BLB outreach are 3-5x higher than cold-email backlink outreach because you're solving a real problem for the recipient, not asking for a favor.
Why this works when other outreach doesn't
Most link-building outreach is some flavor of "Hi, I love your blog, would you link to my article?" Site owners get 30-100 of these per week, almost all useless. Conversion rate: 1-3%.
Broken-link outreach inverts the dynamic. You're not asking the site owner for a favor — you're flagging that one of their links is broken AND suggesting a replacement. Now you're providing value, not extracting it. Conversion rate: 8-15%.
The trick is finding broken links pointing at content YOUR content is a genuine equivalent for. That sourcing problem is what most BLB tutorials skip over.
Step-by-step: from sourcing to email send
The repeatable BLB workflow has 5 phases. Each phase has a specific output, so you can pause between sessions and pick up where you left off.
- 1Pick a topic you have content for. Not "marketing" — be specific. "Cold email subject lines for B2B" or "ROI calculation for HVAC equipment upgrades." Specificity is what separates BLB that converts from BLB that bounces.
- 2Find 10-30 high-DA pages that rank for your topic. Google your target keyword. Open the top 30 results that aren't direct competitors (you're not going to link-build to a competitor's blog).
- 3For each page, scan it for outbound links. Most authority articles cite 5-15 sources. Open all of them in tabs.
- 4Test for dead links. The free Chrome extension "Check My Links" highlights every broken link on a page in red after a 5-second scan. Or Ahrefs/Semrush's site explorer if you have a subscription. You're looking for 404s on outbound links from authority pages.
- 5For each broken link found, check what content WAS there using Wayback Machine (web.archive.org). If it's a topical match for content you have, you've found your target.
- 6Email the site owner. Script below.
The outreach email that converts
Tone matters. You're a peer pointing out an issue, not a beggar asking for a favor. Keep it short — 5-7 sentences — and lead with the broken-link finding, NOT your replacement pitch.
Subject: Quick heads-up — broken link in your [topic] post Hi [Name], I was reading your post on [post title] (great breakdown, especially the [specific section] section) and noticed that the link to [broken-link source] under [exact context where the link appears] is now a 404. Looks like the page got moved or the site went down. If you're looking for a replacement, I wrote up [your topic] at [your URL] which covers the same ground. No pressure either way — just figured you'd want to know about the broken link. Thanks for the post — it genuinely helped me think through [something specific]. [Your name]
Realistic numbers + time investment
Sourcing one good prospect takes 5-15 minutes once you have the workflow down. Writing the email takes another 5 minutes. Conversion rate is 8-15% in our customer base — so 10 prospects = 1-2 backlinks landed.
A focused 90-minute BLB session can produce 6-10 sent emails. Over 4-8 weeks, that's 25-40 emails sent → 3-6 backlinks landed. Not infinite-scale, but the backlinks tend to be high-quality (DA 50-80) because authority pages cite authority pages.
When NOT to use BLB
BLB is not great for new sites with little content yet. The replacement you're suggesting has to be at least as good as the broken-link source — otherwise the site owner has no real reason to link to you over linking to a different alternative.
It's also weak for very local intent (e.g. "HVAC Charlotte"). Local SEO leans more on the chamber/sponsorship/supplier sources from the local link-building playbook than on BLB. BLB shines for content-marketing-driven SEO where you have substantive long-form content other sites would credibly cite.
