Introduction
Broken Link Building is an SEO strategy that helps website owners earn relevant backlinks by finding broken or outdated links on other websites and suggesting a useful replacement from their own site. Instead of asking a website owner for a completely new link, you identify an existing link that no longer works and provide a relevant resource that can replace it.
This approach can benefit both sides. The website owner gets an opportunity to improve their content and user experience by fixing a dead link, while you may earn a valuable backlink to a useful page on your website.
Broken Link Building Process Overview
| Broken Link Building Element | What You Do | Main Purpose |
| Find broken links | Identify dead or outdated links | Discover opportunities |
| Evaluate the source | Check relevance and quality | Prioritize valuable prospects |
| Create or identify content | Provide a useful replacement | Match the original resource |
| Contact website owners | Explain the broken link | Start outreach |
| Suggest your resource | Offer a relevant replacement | Earn a backlink |
| Monitor results | Track responses and links | Measure performance |
In this guide, you will learn what broken link building is, how it works, how to find opportunities, how to conduct effective outreach, common mistakes to avoid, and how to turn the strategy into a repeatable link-building process.
Quick Answer: What Is Broken Link Building?
Broken link building is a link-building technique based on finding links on external websites that lead to pages that no longer exist, are unavailable, or are otherwise broken.
You then determine whether your website has a relevant resource that could replace the missing page. If it does, you can contact the website owner or editor and suggest your resource as a possible replacement.
The basic process is:
- Find relevant websites.
- Identify broken external links.
- Evaluate the broken page and linking website.
- Create or select a suitable replacement resource.
- Contact the website owner.
- Suggest your resource naturally.
- Track responses and acquired backlinks.
The strategy works best when your replacement genuinely improves the page rather than simply being an excuse to request a backlink.
What Is Broken Link Building?
Broken link building is a proactive SEO technique that combines link research, content creation, and outreach.
Imagine that a website published an article several years ago and linked to a useful industry resource. Later, that resource was removed, the URL changed, or the original website disappeared. Visitors clicking the link may encounter a 404 error or an unavailable page.
That creates an opportunity.
If you have a high-quality resource covering the same subject, you can notify the website owner and suggest your page as a potential replacement.
Why Broken Links Create Opportunities
Broken links can negatively affect the user experience because visitors may be sent to pages that no longer provide the expected information.
Website owners therefore have a reason to fix them.
This makes broken link building different from a completely cold backlink request. You are bringing a specific issue to the publisher’s attention and offering a relevant solution.
Broken Link Building vs. Traditional Link Outreach
Traditional outreach often starts with:
“Would you consider linking to my website?”
Broken link building starts with:
“I noticed a resource on your page is no longer available. I have a similar resource that may be useful as a replacement.”
The second approach provides a clear reason for contacting the publisher.
Benefits of Broken Link Building
Earn Relevant Backlinks
The strongest opportunities usually come from websites that already publish content related to your subject.
A contextual backlink from a relevant page can be more useful than a random link from an unrelated website.
Improve Website Visibility
Acquiring relevant external links can help increase your website’s exposure to new audiences and create additional referral-traffic opportunities.
Build Relationships With Website Owners
Good outreach is not only about obtaining one backlink. A helpful interaction with an editor, blogger, or website owner can create opportunities for future collaboration.
Improve Existing Content
The research process can reveal topics that other websites previously considered valuable enough to reference.
These findings can help you identify content gaps and create stronger resources for your own website.
Provide Value Instead of Making a Generic Request
Broken link building has a natural value proposition: you are identifying a problem and presenting a potential solution.
However, the replacement must actually be relevant and useful.
How Does Broken Link Building Work?
The process can be divided into several stages.
Step 1: Choose a Relevant Topic
Start with a topic closely related to your website, products, services, or expertise.
For example, a website about digital marketing might search for broken links related to:
- SEO
- Content marketing
- Keyword research
- Link building
- Technical SEO
- Website analytics
The more closely the topic matches your website, the easier it is to create a useful replacement resource.
Step 2: Find Relevant Websites
Search for websites that publish authoritative content in your industry.
Potential sources include:
- Industry blogs
- Resource pages
- Educational websites
- Professional organizations
- Research publications
- Industry guides
- Community websites
Focus on genuine websites with useful content and a real audience.
Step 3: Find Broken External Links
Review relevant pages and identify links that lead to:
- 404 pages
- Deleted resources
- Expired pages
- Unavailable domains
- Incorrect URLs
- Redirects that no longer provide the intended information
SEO tools and browser extensions can help speed up this process, especially when working with large websites.
Step 4: Investigate the Original Resource
Finding a broken URL is only the beginning.
Try to understand what the original page contained.
Ask:
- What was the original topic?
- Who was the intended audience?
- What information did the page provide?
- Was it a guide, study, statistic, tool, or resource?
- Why did the website link to it?
Understanding the original purpose helps you create a much better replacement.
Step 5: Check Whether You Have a Suitable Replacement
Your existing content may already be an appropriate replacement.
If not, consider creating a new resource.
For example, if a website links to a deleted “SEO Statistics” article, you might create an updated research-based statistics page that covers the same subject.
The goal is not to create something merely similar. The goal is to provide a resource that makes sense in the context of the original link.
Step 6: Evaluate the Linking Website
Not every broken backlink opportunity is worth pursuing.
Consider:
- Topical relevance
- Content quality
- Website reputation
- Audience
- Organic visibility
- Referral potential
- Link placement
- Overall legitimacy
Do not judge a website solely by one third-party SEO metric.
Step 7: Contact the Website Owner
Keep your outreach short, specific, and helpful.
Mention the exact page containing the broken link and explain what you found.
Then introduce your replacement resource only if it is genuinely relevant.
Step 8: Follow Up Professionally
Website owners and editors may receive many emails, so a single unanswered message does not necessarily mean rejection.
A brief follow-up can be reasonable, but avoid sending repeated messages or pressuring the recipient.
Step 9: Track Your Results
Maintain a simple outreach spreadsheet with fields such as:
| Field | Purpose |
| Website | Identify the prospect |
| Page URL | Record the page containing the broken link |
| Broken URL | Document the unavailable resource |
| Replacement URL | Record your suggested resource |
| Contact | Track the relevant person |
| Date contacted | Monitor outreach |
| Follow-up date | Organize follow-ups |
| Response | Record the outcome |
| Link status | Track whether the backlink was acquired |
Types of Broken Links to Look For
Broken Resource Links
These point to guides, research, reports, or other useful resources that have disappeared.
These can be excellent opportunities when your website has a comparable resource.
Broken Statistics and Research Links
Older statistics pages and research reports are frequently replaced or moved.
An updated and well-sourced resource can potentially serve as a replacement.
Broken Tool Links
Websites sometimes link to online calculators, tools, templates, or software that later becomes unavailable.
If you offer a similar or improved tool, this may create a relevant opportunity.
Broken Image or Infographic Links
Visual resources can disappear when websites are redesigned or assets are removed.
However, evaluate the context carefully before proposing a replacement.
Outdated Resource Links
Not every outdated link is technically broken. A page may still work but provide old or inaccurate information.
In some situations, a newer and more useful resource may be worth mentioning to the publisher.
Practical Example of Broken Link Building
Suppose a marketing blog has an article titled “Complete Guide to Keyword Research.”
Inside the article, it links to an external keyword research guide. Several years later, that guide disappears and the link now returns an error.
You discover the broken link and review the original resource.
Your website already has a comprehensive, updated keyword research guide covering the same subject.
You can then contact the blog owner and explain:
- Which page contains the broken link
- Which resource appears to be unavailable
- That you have a relevant updated guide
- Where your guide could potentially fit
The publisher can then decide whether your resource is appropriate.
The important part is that the replacement should make the article better for readers.
Broken Link Building Tools
Several types of tools can make the process faster.
Backlink Databases
SEO platforms can help identify pages, referring domains, historical links, and competing content.
Website Crawlers
Crawlers can scan pages and identify links that return errors or unavailable responses.
Browser Extensions
Link-checking extensions can be useful when manually reviewing resource pages or long-form articles.
Search Engines
Search operators can help discover resource pages and relevant industry content.
For example, searches around phrases such as:
- “useful resources”
- “helpful links”
- “recommended resources”
- “industry resources”
can help identify pages that may contain external references worth reviewing.
Tips and Best Practices
Prioritize Relevance
Relevance should be one of your first filters.
A broken link on a highly authoritative website is not automatically valuable if the subject has nothing to do with your website.
Make the Replacement Better
Do not simply reproduce an old resource.
Where possible, improve it with:
- Updated information
- Better structure
- Original research
- Clear explanations
- Helpful examples
- Visual assets
- Reliable references
Personalize Outreach
Avoid sending exactly the same generic message to hundreds of websites.
Mention the specific article and broken resource so the recipient understands why you contacted them.
Keep Outreach Short
Website owners generally do not need a long explanation of your SEO strategy.
Clearly explain the problem and provide the potential solution.
Focus on User Value
The strongest question to ask is:
Would this replacement genuinely help the readers of this page?
If the answer is no, the opportunity probably is not worth pursuing.
Maintain a Prospect Database
Record your prospects and outreach history.
This prevents duplicate outreach and makes it easier to identify which approaches produce the best results.
Don’t Depend on One Metric
Third-party metrics can be useful for prioritization, but they should not be the only factor.
Consider relevance, editorial quality, audience, traffic potential, and context together.
Common Broken Link Building Mistakes
1. Suggesting an Irrelevant Page
A website owner is unlikely to replace a broken link with a resource that does not cover the same subject.
2. Creating Content Only for a Backlink
If the replacement resource has little value, it becomes much harder to justify the outreach.
Create content that would be useful even without the backlink opportunity.
3. Sending Generic Emails
A message that could have been sent to any website often feels like mass outreach.
Personalize the key details.
4. Chasing Every Broken Link
Not every broken link represents a worthwhile opportunity.
Prioritize relevant websites and pages with genuine value.
5. Overusing Follow-Ups
One or two polite follow-ups may be reasonable, but repeated messages can damage your reputation.
6. Ignoring the Original Context
A replacement should match the intent of the original resource as closely as possible.
7. Focusing Only on SEO Metrics
A website with strong metrics may still have little relevance to your audience.
Always consider the human value of the link.

Conclusion
Broken Link Building combines SEO research, useful content, and relationship-based outreach to create potential backlink opportunities.
The process is straightforward: find relevant websites, identify broken links, understand the original resource, provide a useful replacement, contact the publisher, and track the results.
However, success depends on quality rather than volume. A relevant resource on a legitimate website is generally a much better opportunity than dozens of unrelated prospects.
The best approach is to treat broken link building as a way to help website owners improve their content while making your own resources more discoverable. When your replacement genuinely benefits readers, your outreach becomes more natural and more valuable.
