What Is Broken Link Building?
Broken link building is an SEO strategy where you find broken (dead) links on other websites, create content that replaces the dead resource, and then ask the site owner to swap the broken link with a link to your new content.
Think about it: the internet is full of dead links. Pages get deleted, domains expire, URLs change, and entire websites shut down. Every one of those broken links represents a potential backlink opportunity for you.
When a resource page links to a URL that returns a 404 error, the site owner probably does not even know about it. And that dead link is hurting their user experience. You are doing them a genuine favor by flagging it.
Here is the beauty of this approach: you are not cold-pitching a stranger. You are reaching out with a problem (the broken link) and a solution (your replacement content). That changes the entire dynamic of the outreach conversation.
Unlike guest posting or directory submissions, broken link building creates a natural, editorial backlink from a page that already has authority. The link was already there. You are simply replacing the dead destination with a live one.
This is one of the few link building tactics that genuinely works at scale, feels ethical, and produces links that move the needle on rankings.
Why Broken Link Building Works
Most outreach emails get ignored. The average cold email response rate in link building hovers around 5-8%. But broken link building campaigns consistently hit 15-20% reply rates or higher.
Why? Three reasons.
1. The Psychology of Reciprocity
When you tell a webmaster about a broken link on their site, you are doing them a favor. You are identifying a problem they did not know they had. That triggers a natural sense of reciprocity.
People want to help people who have helped them. By pointing out the issue first, you build goodwill before making any ask. The link swap becomes a natural next step, not a forced transaction.
2. It Is a Genuine Win-Win
This is not some manufactured "value proposition." You are solving a real problem. The webmaster gets a fixed link. Their visitors get a working resource. You get a backlink. Everyone wins.
Compare this to a generic "Hey, I wrote a great article, would you link to it?" pitch. There is zero incentive for the webmaster in that scenario. With broken link building, the incentive is baked into the outreach itself.
3. The Success Rate Is Remarkably High
Because you are offering something tangible (a fix for their site), site owners are far more likely to act. Many experienced link builders report conversion rates between 5-15% on the link placement itself, which is significantly higher than most other link building methods.
When you combine a high reply rate with a strong conversion rate, the math gets very attractive. Even a modest campaign targeting 100 prospects can yield 5-15 quality backlinks. That is excellent ROI for any link building effort.
The highest-converting campaigns target resource pages specifically. These are curated lists of links on a topic, and the webmaster has a vested interest in keeping every link working. When you find a dead link on a resource page, you have found gold.
The Step-by-Step Process
Now let's get into the actual process. I am going to break this down into five clear steps that you can follow from start to finish.
Find Resource Pages in Your Niche
The first step is finding pages that are likely to have broken outbound links. The best targets are resource pages, "best of" lists, link roundups, and curated guides.
Use these Google search operators to find resource pages:
"your keyword" + "resources""your keyword" + "useful links""your keyword" + "recommended sites""your keyword" + inurl:resources"your keyword" + inurl:links"your keyword" + "helpful resources"
For example, if you are in the digital marketing space, you might search for "SEO" + "resources" + inurl:links. This will surface pages that curate links about SEO topics.
Focus on pages with high Domain Authority (DA 30+). A broken link on a DA 60 resource page is worth far more than one on a DA 10 blog. Quality over quantity always wins in link building.
Identify Broken Links on Those Pages
Once you have a list of resource pages, you need to find which links on those pages are actually broken. There are several ways to do this:
- Check My Links (Chrome Extension) - The fastest method for checking individual pages. Install it, visit the resource page, and click the extension. It highlights broken links in red instantly.
- Ahrefs Broken Backlinks Report - Enter a competitor domain and go to the "Broken Backlinks" report. This shows you every external site linking to dead pages on that domain. Incredibly powerful for finding opportunities at scale.
- Screaming Frog - Crawl a resource page and filter by "External Links" with a 404 status code. This is the most thorough method for auditing a single site.
- Ahrefs Content Explorer - Search for a topic, filter by "one page per domain," and check for pages with broken outbound links. This gives you a huge list of prospects in minutes.
The best approach is to combine multiple tools. Use Ahrefs for bulk discovery and Check My Links for quick verification. This two-step process ensures you are working with real broken link opportunities, not false positives.
Create Better Content (or Match Existing)
Before you reach out, you need content that can replace the dead resource. This is where many people make a critical mistake: they try to pitch content that does not match what the dead link pointed to.
Here is the right approach:
- Check the Wayback Machine - Use web.archive.org to see what the dead page used to look like. This tells you exactly what content the webmaster originally chose to link to.
- Match the intent - Your replacement content should serve the same purpose as the original. If the dead link pointed to a statistics page, create a statistics page. If it was a how-to guide, create a how-to guide.
- Make it better - Do not just match the original. Exceed it. Make your version more comprehensive, more up-to-date, better designed, and more useful. This makes your pitch irresistible.
Sometimes you already have existing content that is a natural fit. In that case, there is no need to create something new. Simply identify which piece of your existing content best matches what the dead link used to point to.
The closer your content matches the original dead resource, the higher your conversion rate will be. Webmasters are not looking to add random new links. They want to fix the broken experience for their readers with a relevant replacement.
Reach Out to the Site Owner
Now comes the outreach. This is where broken link building either succeeds brilliantly or falls flat. The difference comes down to how you frame the email.
Key principles for your outreach:
- Lead with the broken link - Open by identifying the problem. Do not lead with your content or your ask.
- Be specific - Name the exact page and the exact broken link. Generic emails get deleted immediately.
- Mention the dead URL - Show you have actually visited their page and found the issue. This proves you are not sending a mass template.
- Suggest your replacement casually - Position your content as "one option" to replace the dead link. Do not be pushy. Let them decide.
- Keep it short - Under 150 words. Webmasters are busy people. Respect their time.
- Personalize every email - Reference something specific about their page, their site, or their niche. This turns a template into a conversation.
Finding the right email address matters too. Check the website's about page, contact page, or use tools like Hunter.io to find editorial email addresses. Avoid generic info@ addresses when possible. You want to reach the person who actually manages the content.
Follow Up
Most broken link building guides skip this step. But it is arguably the most important one. A single follow-up email can double your conversion rate.
Here is the follow-up framework:
- Wait 5-7 days after your initial email before following up.
- Keep it even shorter than your first email. 2-3 sentences is ideal.
- Reference your original email without repeating everything. Just bump the thread.
- Add one new piece of value if possible. Maybe you found another broken link on their page. Or you have updated your resource with new data.
- Do not follow up more than twice. Two follow-ups is the sweet spot. After that, you are just annoying someone.
Most people who will say yes do so after the first follow-up, not the initial email. They saw your first message, meant to respond, and then got distracted. The follow-up is your reminder.
The Broken Link Building Workflow
Here is the complete broken link building process visualized from start to finish. Each step flows naturally into the next, creating a repeatable system you can run every week.
The Outreach Funnel: Realistic Numbers
One of the biggest mistakes in broken link building is expecting every outreach email to land a link. Let's set realistic expectations with an outreach funnel based on industry benchmarks.
These numbers might look modest. But consider this: if you run this funnel once per week across different niches and resource pages, you are looking at 20-40 high-quality backlinks per month. That is more than enough to move the needle for most websites.
Broken Link Building for AI Visibility
Here is something most link builders are not thinking about yet: broken link building does not just improve your Google rankings. It directly impacts your visibility in AI-generated answers.
Large language models like ChatGPT, Claude, Gemini, and Perplexity do not just pull information from thin air. They are trained on web content, and they increasingly cite sources in their answers. The brands and domains that get cited most share one thing in common: strong backlink profiles from authoritative sources.
Why Backlinks Matter for AI Citation
AI models assess entity authority when deciding which sources to reference. Entity authority is built through a combination of signals, and one of the most powerful signals is your backlink profile.
When your website has backlinks from authoritative resource pages, university sites, government pages, and industry-leading publications, AI models treat your brand as a more credible source. This means you are more likely to be cited when someone asks an AI assistant a question related to your expertise.
AI models trust brands with strong backlink profiles from authoritative sources. Building high-authority backlinks through broken link building increases your entity authority, making AI models more likely to cite your content in their responses. This is the foundation of Answer Engine Optimization (AEO).
Broken link building is uniquely suited for this because the links you earn are:
- Contextual and editorial - They sit within relevant, curated content. AI models weigh contextual links more heavily than random directory listings.
- From authoritative pages - Resource pages tend to have strong authority themselves, often from .edu, .gov, or high-DR domains.
- Topic-relevant - The link points from a topically related page to your content, reinforcing your topical authority in that space.
- Natural and organic - There are no footprints, no spammy patterns. These are the types of links that AI training data values most.
If you want to future-proof your SEO strategy, combine traditional broken link building with an AEO mindset. Every high-quality backlink you earn is not just a ranking signal for Google. It is also a trust signal for every AI model that processes web data.
Real Outreach Email Templates
Here are battle-tested email templates that consistently produce results. Use these as starting points, but always personalize them for each prospect.
Template 1: The Classic Broken Link Pitch
Hey [Name],
I was reading your page on [topic] today and noticed one of the links seems to be broken. The link to [dead resource name] on [specific page URL] returns a 404.
Just thought you would want to know! I actually published a similar resource on [topic] recently that could work as a replacement: [Your URL].
Either way, hope that helps. Love the resource page, by the way. Already bookmarked a few of the other links.
Cheers,
[Your Name]
Template 2: The Multi-Broken-Link Approach
Hey [Name],
I was going through your [topic] resource page and found a couple of links that seem to be dead:
1. [Dead URL 1] - returns 404
2. [Dead URL 2] - domain expired
3. [Dead URL 3] - redirects to unrelated page
For the [specific dead link], I recently put together a comprehensive guide on that exact topic: [Your URL]. It covers [brief description of what it includes].
Figured this might save you some time tracking down replacements. Great list otherwise!
Best,
[Your Name]
The multi-broken-link approach works especially well because it demonstrates you have genuinely audited their page. You are providing even more value by identifying several issues, which makes the ask feel smaller in comparison.
Template 3: The Follow-Up
Hey [Name],
Just bumping this up in case it got buried. The broken link on [page name] is still showing a 404. Happy to help if you need a replacement suggestion.
No worries either way!
[Your Name]
Templates are starting points, not scripts. The more you personalize each email (mention their latest blog post, reference their company, comment on a specific resource they have listed), the higher your response rate. Spend 60 seconds personalizing each email. That small investment pays off enormously.

Common Mistakes to Avoid
After running hundreds of broken link building campaigns, here are the mistakes we see most often. Avoid these and your success rate will jump significantly.
1. Pitching irrelevant content. The number one reason broken link pitches fail is that the replacement content does not match the dead resource. Always check the Wayback Machine first.
2. Sending mass, generic emails. If your email reads like a template, it will be treated like spam. Personalize every single one.
3. Targeting low-authority pages. A broken link on a DA 5 blog is not worth your time. Focus on DA 30+ sites with real traffic and editorial standards.
4. Forgetting to follow up. Half of your links will come from follow-up emails. Skipping them means leaving links on the table.
5. Creating thin replacement content. If your replacement page is a 300-word post, no one is going to link to it. Make your content genuinely better than what was there before.
6. Being too aggressive in the ask. Phrases like "I would really appreciate a link" or "Can you link to my site?" sound pushy. Instead, casually suggest your content as one option.
7. Not verifying the broken link. Sometimes a page is temporarily down or returns a soft 404. Always double-check before reaching out. Flagging a link that is not actually broken destroys your credibility.
Scaling Your Broken Link Building
Once you have the basic process down, it is time to scale. The key is building systems, not just running one-off campaigns.
Build a Prospect Database
Create a spreadsheet or use a tool like BuzzStream to track every resource page in your niche. Include columns for the URL, domain authority, number of outbound links, contact email, outreach status, and response. This becomes your master list that you can mine repeatedly as you publish new content.
Create a Content Library
Instead of creating new content for every broken link you find, build a library of comprehensive, link-worthy resources in your niche. When you find a broken link opportunity, you can often match it to something you have already published. This dramatically reduces the time from discovery to outreach.
Batch Your Work
The most efficient approach is to batch each step of the process:
- Monday: Prospect research. Find 50-100 new resource pages.
- Tuesday: Broken link identification. Run through your prospect list and flag all dead links.
- Wednesday: Content matching. Map your existing content to the broken link opportunities. Identify gaps where new content is needed.
- Thursday: Outreach day. Write and send all emails with personalization.
- Friday: Follow-ups and tracking. Follow up on last week's outreach and update your tracking spreadsheet.
Leverage Virtual Assistants
Steps 1 and 2 (finding resource pages and identifying broken links) can be partially delegated to a trained virtual assistant. Create clear SOPs with screenshots, and a VA can handle the prospecting while you focus on the high-leverage activities: content creation and outreach.
One of the fastest ways to scale is to plug your competitors' domains into Ahrefs and pull their broken backlinks. Every dead page on a competitor's site represents a link that someone was willing to give. If you create a better version of that dead page, you can reach out to every site that linked to it. One dead competitor page can yield dozens of link opportunities.
Track Your Metrics
You cannot improve what you do not measure. Track these metrics for every campaign:
- Prospects found per hour of research
- Emails sent per campaign
- Reply rate (aim for 15-20%+)
- Link placement rate (aim for 5-10% of emails sent)
- Average DA of earned links
- Time per link from prospect to placement
- Cost per link (your time + tool costs)
Over time, these numbers will show you exactly where your process is strong and where it needs optimization. Maybe your reply rate is great but your conversion rate is low (content matching issue). Or maybe your conversion rate is high but you are not finding enough prospects (research process issue). The data tells the story.
Broken link building works because it solves a real problem for webmasters while earning you high-quality, editorial backlinks. The process is simple: find resource pages, identify broken links, create matching content, and pitch the site owner with a helpful email. With a systematic approach and consistent follow-ups, you can earn 20-40 quality backlinks per month. In the age of AI search, these authoritative links also strengthen your entity authority, making your brand more likely to be cited by AI models. Start small, track your metrics, and scale once you have a repeatable system.
