Broken Link Building: Step-by-Step Guide to Earning Backlinks from Dead Links
Learn how to execute broken link building campaigns from scratch. Find broken links on relevant sites, create the right replacement content and earn quality backlinks with this proven technique.
Broken link building is one of the few link building techniques where you genuinely offer value to the editor before asking for anything in return. The premise is simple: find a broken link on a relevant site in your industry, have or create equivalent content to the broken link, and contact the editor to suggest replacing the dead link with yours. The editor wins (their site improves), you win (you earn a backlink). It delivers some of the highest outreach conversion rates in link building.
Why Broken Link Building Works
Most link building techniques ask for something without giving anything first. Cold outreach for guest posts lands when the editor has no context of who you are. Broken link building arrives with a gift: "I found a problem on your site and I have the solution." This investment in the value proposition completely changes the conversation dynamic.
Conversion data confirms it. A standard outreach campaign achieves 3–8% response rates. A well-executed broken link building campaign can reach 10–25% because the first message is helpful to the editor regardless of whether they accept the link. Combined with the fact that the backlinks earned are genuinely editorial and relevant, it's a high-ROI technique for sites at any DA stage.
Step 1: Finding Pages with Broken Links
There are three main methods to find broken link building opportunities:
- Ahrefs Content Explorer: Search for content in your niche by topic and filter by "Broken backlinks" to see which pages have broken links pointing to them. You can also directly search for resource pages in your industry.
- Check My Links (Chrome extension): Visit resource pages, directories and articles in your niche and run the extension. It highlights all broken links (in red) in seconds with no premium account needed.
- Ahrefs Site Explorer on competitors: Site Explorer → competitor URL → Best by links → filter by "404". You see all competitor pages that no longer exist but have many backlinks — perfect candidates to create replacement content for.

Not all broken links are worth the same energy. Before creating content or sending emails, filter opportunities by these criteria:
| Criterion | Minimum | Ideal |
|---|---|---|
| DA of site with broken link | DA 30+ | DA 50+ |
| Topical relevance | Same general niche | Same exact category |
| Referring domains to broken resource | 5+ referring domains | 20+ referring domains |
| Has published contact info | Email or form | Direct editor email |

Step 3: Creating the Replacement Content
Before contacting the editor, have the replacement content ready or identified. Options:
- You already have equivalent content: The ideal case. If the broken link was to "link building guide for SaaS" and you have that article published, you can reach out immediately.
- Create new content: If the opportunity is strong enough (DA 60+ with 20+ referring domains to the broken resource), it may be worth creating a dedicated article. Use Wayback Machine to see what the original content looked like and create something equal or better.
- Adapt existing content: You have a similar but not identical guide. You can update the title and intro to better match what the broken link was pointing to.
Step 4: The Outreach Email That Converts
The broken link building email structure must be specific: value first (the problem you found), then the solution (your content), never in reverse. A template that works:
Subject: Broken link in [article name] Hi [name], While reading your article "[title]" I noticed the link to [resource description] no longer works (returns a 404 error). We have an updated resource that covers exactly that topic: [Your content URL] It might be a good replacement for your readers. Best, [Your name]
Three rules of broken link building outreach: (1) Mention the specific article where the broken link appears, not just the site. (2) Describe the broken link in terms of what it did, not the URL that no longer exists. (3) Don't explicitly ask for the link — suggest your resource may be useful and let the editor decide.

Scaling Broken Link Building
The limitation of this technique is prospecting time. To scale without losing quality: use Ahrefs Alerts to get notifications when relevant URLs in your niche return 404 — you capture opportunities in real time. Build a spreadsheet with columns: URL with broken link, DA, editor email, broken resource (description), your replacement URL, outreach status. Process 10–20 opportunities per week rather than sporadic large batches.
With a systematic process, broken link building can generate 3–8 quality backlinks per month with 2–3 weekly hours of work — one of the best effort-to-result ratios in technical link building.
Esbuenisimo Links integrates broken link building into broader campaigns combining PR in media, guest posts and links on verified platforms, maximizing monthly DA growth for each client.
Frequently Asked Questions
How many broken link building opportunities typically exist in a niche?+
It depends on the maturity and size of the niche. In established niches (health, finance, technology, digital marketing): hundreds of opportunities because years of accumulated content inevitably lead to pages disappearing or moving. In newer or smaller niches: 20–50 quality opportunities may be more realistic. The most efficient tool for quantifying: Ahrefs Content Explorer with broken backlinks filter on your topic. In 30 minutes you can have a list of 50–100 opportunities to then filter by DA and relevance.
What conversion rate can I expect from broken link building outreach?+
Rates vary by email quality, replacement relevance and contact volume. Typical ranges: 5–10% response rate with generic outreach. 10–20% when the email is personalized and mentions the specific article. 20–30% when the proposed replacement is clearly better than the original (more updated, more complete). For context: standard guest posting outreach has 3–8% rates. Broken link building converts better because the first message offers genuine value regardless of whether they accept.
Is it worth creating new content just for a broken link building opportunity?+
Yes, when the value equation is favorable: if the broken resource has 30+ referring domains and the site it appears on has DA 60+, a well-earned backlink can be worth the equivalent of weeks of SEO work. Criteria to justify creating new content: (1) The original broken URL received enough traffic or links to justify replicating it. (2) Multiple sites have broken links to the same resource — you create the content once and propose it to all of them. (3) The content is useful to your audience regardless of the links — so it has value even if the outreach doesn't convert.
How long after a URL breaks is it still a good broken link building opportunity?+
The best opportunities are the most recent: pages that broke less than 6–12 months ago are more likely to have editors who still actively maintain the content and can make the change. URLs broken 3–5 years ago are often in abandoned articles or sites no longer actively maintained. However, if the broken link is in an evergreen high-DA article that still receives traffic (verifiable in Ahrefs), the age of the broken URL isn't necessarily disqualifying — the editor may be willing to update it.
Does broken link building still work after Google's algorithm updates?+
Yes, and it has an important algorithmic advantage: backlinks earned through broken link building are genuinely editorial. The editor chose to include your link because the replacement content was useful for their readers, not because they were artificially incentivized. This makes it one of the most algorithm-resistant link profiles available. Unlike PBNs or directories that Google can devalue in bulk with a single update, an editorial link in a quality DA 60 article is exactly the type of backlink Google wants to promote.
