Broken link building is one of the most effective white-hat techniques for earning high-quality backlinks. It works because you’re helping website owners fix a problem while gaining a valuable link for your site. Everyone wins.
This strategy involves finding dead links on other websites, creating content that matches what the original link pointed to, and then reaching out to ask for a replacement link. When done right, broken link building can significantly boost your search rankings and domain authority.
Let’s walk through exactly how to use broken link building to grow your website’s backlink profile.
What Is Broken Link Building?
Broken link building is an outreach-based SEO tactic. You find links that lead to 404 error pages on websites in your niche. Then you contact the site owner and suggest your content as a replacement.
This approach works better than cold outreach because you’re providing genuine value. Website owners don’t want broken links hurting their user experience or SEO. By alerting them to the problem and offering a solution, you make their job easier.
Understanding what a 404 status code means is essential before you start. A 404 error tells visitors that the page they’re looking for no longer exists. These dead ends frustrate users and can negatively impact a site’s search performance.
Why Broken Link Building Works So Well
Several factors make this strategy particularly effective:
- High success rates: You’re solving a problem, not just asking for a favor
- Scalable approach: Thousands of broken links exist in every niche
- Quality links: You target existing editorial links, not manufactured ones
- White-hat method: Google approves of this approach to link building
According to Ahrefs’ research on broken link building, this tactic remains one of the most reliable ways to earn contextual backlinks from authoritative websites.
Before starting any link building campaign, you should know how to evaluate a backlink to ensure you’re pursuing links that will actually help your rankings.
Step-by-Step: How to Use Broken Link Building
Step 1: Find Broken Links in Your Niche
Start by identifying dead links on websites relevant to your industry. There are several methods to do this:
Use SEO tools: Platforms like Ahrefs, SEMrush, and Moz can scan websites for broken outbound links. Enter a competitor’s URL or a resource page in your niche to find opportunities.
Check resource pages: Many websites maintain resource pages with lists of helpful links. These pages often contain outdated URLs. Search Google using queries like:
- “your keyword” + “resources”
- “your keyword” + “useful links”
- “your keyword” + “recommended sites”
Analyze competitor backlinks: Look at where your competitors got their links. Some of those linking pages may now contain broken links. Learning how to do competitor backlink analysis gives you a significant advantage in finding these opportunities.
Step 2: Verify the Broken Links
Before reaching out, confirm that the links are actually broken. Tools like Check My Links (a Chrome extension) or Screaming Frog’s broken link checker can help you verify dead links quickly.
Also check the Wayback Machine to see what content originally existed at the broken URL. This helps you understand what type of replacement content you’ll need to create.
Step 3: Create or Identify Replacement Content
Now you need content that can serve as a suitable replacement for the dead link. You have two options:
Use existing content: If you already have a piece that covers the same topic as the dead page, you’re ready to reach out.
Create new content: Build a resource that matches or exceeds the quality of the original. Make it comprehensive, well-researched, and genuinely useful.
Your replacement content should closely align with what the original link offered. If the broken link pointed to a guide about email marketing tips, your replacement should cover that same topic.
Step 4: Find Contact Information
Locate the email address of the website owner or content manager. Check these places:
- The website’s contact page
- About page or team page
- Author bio on the page with the broken link
- LinkedIn or Twitter profiles
- WHOIS lookup tools
Avoid using generic contact forms when possible. Direct emails to specific people get better response rates.
Step 5: Craft Your Outreach Email
Your email should be friendly, helpful, and concise. Here’s a template you can customize:
Subject: Quick heads up about a broken link on [Website Name]
Hi [Name],
I was reading your excellent article on [topic] and noticed that one of your links isn’t working anymore. The link to [original resource] on [page URL] leads to a 404 error.
I thought you’d want to know since broken links can hurt user experience.
If you’re looking for a replacement, I recently published a guide on the same topic: [your URL]. It covers [brief description of what your content offers].
Either way, thanks for putting together such a helpful resource!
[Your name]
Keep your outreach genuine. Don’t be pushy about getting the link. Focus on being helpful first.
Step 6: Follow Up Strategically
Many website owners miss your first email. Send a polite follow-up after 5-7 days if you don’t hear back. Limit yourself to two follow-ups maximum.
Track your outreach using a spreadsheet or CRM tool. Note the date contacted, response received, and outcome for each prospect.

Common Mistakes to Avoid
Many people fail at broken link building because they make these errors:
Poor content match: Your replacement must closely match the original content’s topic and intent. Don’t suggest your homepage when the broken link pointed to a specific guide.
Generic outreach: Personalize every email. Mention something specific about their website. Mass template emails rarely work.
Targeting low-quality sites: Focus on websites with real authority and traffic. A link from a spammy site won’t help your SEO. Understanding backlink relevance vs domain authority will help you prioritize the right opportunities.
Giving up too soon: Broken link building requires patience. Response rates typically range from 5-15%. Keep prospecting and reaching out consistently.
