Broken link building is a link-earning technique that helps other website owners while helping your own site. The idea is simple: find links on relevant websites that point to pages that no longer exist, create or identify a useful replacement on your site and politely let the site owner know. They fix a problem on their site, and you have a good chance of earning a relevant link.
This guide explains how to find broken links, choose the right opportunities, create replacement content and write outreach emails that get positive responses.
Why Broken Link Building Works
- It provides value: broken links hurt the user experience on the linking site.
- It is relevant: the original link shows the site owner wanted to reference that topic.
- It feels helpful: your email offers a fix, not just a request.
- It scales reasonably: one dead resource can have many sites linking to it.
Step 1: Find Relevant Pages with Broken Links
Resource pages
Many websites maintain lists of helpful resources. These often contain old links. Search for terms like “your topic” + “resources”, “useful links” or “recommended tools”.
Browser extensions and crawlers
Link-checking extensions highlight broken links on any page you visit. Site crawlers can scan entire websites for broken outbound links.
Dead competitor or industry pages
Use an SEO tool to find pages in your niche that return 404 errors but still have many backlinks. Each linking site is a potential opportunity.
Step 2: Understand the Missing Content
Before offering a replacement, find out what the broken page used to contain. Archive services can sometimes show older versions of pages. Review the anchor text and surrounding context on the linking site as well. Your replacement should match or improve on the original’s purpose.
Step 3: Create or Choose a Replacement
If you already have a relevant page that covers the topic well, you can use it. If not, consider creating a better resource, especially when many sites linked to the dead page. Make it up to date, comprehensive and genuinely useful.

Step 4: Find the Right Contact
Look for the author of the page, the site editor or a contact form. Personal outreach to the right person is far more effective than a generic support email.
Step 5: Write a Helpful Outreach Email
Keep it short, friendly and specific:
- Mention the exact page where you found the broken link
- Identify the broken link and its anchor text
- Suggest your resource as a possible replacement, briefly explaining why it fits
- Thank them, and make it clear there is no pressure
Avoid long templates, flattery that sounds automated and repeated follow-ups. One polite follow-up after a week is usually enough.

|---|---|
| Friendly greeting | Personal, respectful start |
| Thanks | Appreciation, no pressure |
Step 6: Track Your Outreach
Use a spreadsheet to record the site, page, broken URL, contact, date emailed, follow-up and result. Tracking helps you avoid duplicate emails and learn which approaches work best.
Tips for Better Success Rates
- Prioritise relevant sites with real audiences
- Personalise every email
- Offer genuinely better content than the original
- Mention other broken links you noticed as an extra favour
- Be patient; responses can take weeks
Common Mistakes
- Offering irrelevant pages as replacements
- Sending mass emails to hundreds of sites
- Being pushy or sending many follow-ups
- Creating thin replacement content
- Targeting low-quality sites only for links
Fixing Your Own Broken Links
Broken link building also reminds you to check your own site. Broken outbound links hurt your readers’ experience. Run a regular check and update or remove dead links. If other sites link to your deleted pages, redirect them to relevant live pages so you keep the value of those links.
Real-World Example
A gardening blog found that a popular composting guide from an old university extension page had been removed, yet over sixty websites still linked to it. The blogger wrote a detailed, illustrated composting guide covering everything the old page did plus updated methods. She contacted the editors of thirty relevant sites, and nine replaced the broken link with her guide over the next two months, bringing relevant links and steady referral traffic.
Frequently Asked Questions

Conclusion
Broken link building is a practical, helpful way to earn relevant links. Find dead links on quality pages in your niche, understand what was lost, offer a better replacement and reach out politely.
