If you’re trying to improve your website’s search rankings, backlinks still matter—a lot. But many link building tactics are slow, expensive, or spammy.
Broken link building is different.
It’s one of the most practical and ethical SEO strategies because it helps both sides: you gain a backlink, and the website owner fixes a broken link on their site.
In this guide, you’ll learn exactly what broken link building is, why it works, and how to do it step-by-step—even if you’re new to SEO.
What Is Broken Link Building?
Broken link building is an SEO strategy where you:
- Find broken (dead) links on other websites
- Create or identify relevant content on your site
- Contact the site owner and suggest replacing the broken link with your content
Since broken links create a poor user experience, many website owners are happy to fix them.
This creates a win-win situation:
- The site owner fixes a dead link
- You earn a valuable backlink
Why Broken Link Building Works So Well
Many SEO tactics involve asking for favors. Broken link building works because you’re actually helping the website owner.
Here’s why it’s effective:
1. Website Owners Want to Fix Broken Links
Broken links hurt user experience and can negatively affect SEO.
If you help someone find one and offer a relevant replacement, you’re providing value.
2. It’s White-Hat SEO
This method follows Google’s guidelines because you’re not buying links or using spam tactics.
3. High-Authority Sites Often Have Broken Links
Large websites, blogs, and resource pages accumulate broken links over time, creating opportunities for backlinks.
4. You Get Contextually Relevant Links
The replacement link is placed within relevant content, which is exactly what search engines value.
How Broken Link Building Works (Step-by-Step)
Let’s break down the exact process.
Step 1: Find Relevant Websites in Your Niche
Start by searching for resource pages or blog posts related to your topic.
Example search queries:
- SEO resources
- digital marketing useful links
- best tools for bloggers
- keyword research guide resources
These pages often contain many outbound links, which increases the chance of broken ones.
Step 2: Find Broken Links
Use SEO tools or browser extensions to detect broken links.
Popular options include:
- Ahrefs
- SEMrush
- Screaming Frog
- Check My Links (Chrome extension)
These tools quickly scan pages and highlight links returning 404 errors.
Example:
A marketing blog links to a guide that no longer exists.
That’s your opportunity.
Step 3: Create or Match Relevant Content
Now you need a page that fits the same topic as the broken link.
You can either:
- Use an existing blog post
- Create a new, better piece of content
Example:
Broken link topic:
“Beginner’s Guide to Keyword Research”
Your replacement content could be:
“Keyword Research for Beginners: Step-by-Step Guide”
The closer the match, the higher your success rate.
Step 4: Contact the Website Owner
Reach out politely and let them know about the broken link.
Your goal is helpful outreach, not aggressive promotion.
Simple email example:
Subject: Quick heads-up about a broken link
Hi [Name],
I was reading your article on [Topic] and noticed one of the links appears to be broken.
The link pointing to [broken resource] returns a 404 error.
I recently published a similar guide on the same topic that might work as a replacement if you’re updating the page.
Here it is:
[Your URL]
Either way, I thought you’d want to know about the broken link.
Thanks for the great resource!
Best,
[Your Name]
Keep the message short, helpful, and respectful.
Example of Broken Link Building in Action
Imagine you run a fitness blog.
You find a health website linking to an article called:
“Top 10 Home Workout Routines”
But the page no longer exists.
You create a new article:
“10 Effective Home Workout Routines for Beginners”
Then you contact the site owner suggesting your article as a replacement.
If they update the link, you gain a relevant backlink from a health website.
Tips to Improve Your Success Rate
Broken link building works best when you focus on quality.
Target Resource Pages
Pages with long lists of resources often contain outdated links.
Offer Better Content
If your content is more detailed and updated, your chances increase.
Personalize Your Outreach
Avoid mass emails. Mention the page you actually read.
Focus on Relevance
Your content must match the original topic closely.
Be Patient
Link building is a numbers game. Not every email gets a response.
Common Mistakes to Avoid
Even experienced marketers make these mistakes.
Sending spammy outreach emails
Website owners ignore generic templates.
Replacing unrelated links
If the content doesn’t match, it won’t work.
Ignoring content quality
A weak article won’t convince anyone to link to it.
Targeting low-quality sites
Focus on reputable websites with real traffic.
