Introduction
One of the most effective and ethical link-building strategies in SEO is broken link building. Instead of begging for links or spamming outreach emails, you provide real value by helping webmasters fix dead or outdated links on their websites.
Here’s how it works:
- You find websites in your niche that are linking to broken resources (404 pages, outdated guides, expired tools).
- You reach out to the webmaster, letting them know about the broken resource.
- You recommend your own content as a replacement — ideally, a fresher, more relevant, high-quality resource.
Done right, this creates a win-win: the site owner improves user experience by removing dead links, and you earn a high-quality backlink.
But the key challenge is step one: How do you identify broken resources to pitch your content? In this first half, we’ll dive into what broken resources are, why they matter, and detailed strategies for uncovering them.
What Are Broken Resources?
Broken resources are assets on the web that no longer function, yet are still linked to from other websites. They include:
- Dead Web Pages (404 Errors): The page has been deleted or the site restructured.
- Expired Domains: Websites that have gone offline but still have inbound links.
- Outdated Tools or Software: A free calculator, plugin, or app that no longer works.
- Old Research Reports: Studies or whitepapers that have been removed or archived.
- Removed PDFs or Media: Downloads no longer available from the host server.
When these resources break, all the backlinks pointing to them lose their value and create a poor user experience. That’s your opportunity.
Why Pitching Content for Broken Resources Works
1. It Solves a Real Problem
Webmasters hate broken links because they:
- Hurt SEO rankings (Google discourages linking to dead pages).
- Damage user experience (visitors bounce away).
- Signal neglect or outdated site maintenance.
By pointing out the broken resource, you become genuinely helpful.
2. It’s a Natural Fit for Your Content
If you have a relevant replacement (e.g., a new guide, updated research, or a working tool), recommending it feels authentic — not forced.
3. It Yields High-Quality Backlinks
Broken links often come from authority sites that have been around for years. These backlinks are more valuable than low-quality directory submissions.
4. It’s Scalable
There are millions of broken links across the web. Once you master the process, you can scale it with tools and automation.
Step 1: Understand the Types of Broken Links You Can Target
Not every broken resource is worth your time. Focus on those that align with your niche and where your content makes sense as a replacement.
High-Priority Targets
- Industry Guides & Evergreen Resources: Example: An “Ultimate Guide to SEO” from 2015 that’s now offline.
- Niche Tools or Calculators: Example: A keyword tool that was shut down.
- Government or Educational Resources: Broken .gov or .edu references (these yield extremely valuable backlinks).
- Widely Cited Research: Old reports that were frequently linked in blog posts and articles.
Low-Priority Targets
- Links on spammy, low-authority blogs.
- Irrelevant niches (even if the link is broken, if your content isn’t a match, don’t bother).
Step 2: Use Google Search Operators
One of the simplest ways to identify broken resources is with advanced Google search operators.
Examples:
keyword + “useful resources”keyword + “links”keyword + “inurl:resources”keyword + “intitle:resources”
These searches surface resource pages — curated lists of links where broken resources are common.
Process:
- Search using operators in your niche (e.g., “content marketing inurl:resources”).
- Visit the resource pages.
- Use a Chrome extension like Check My Links or Broken Link Checker to highlight dead links.
- Record the broken links in a spreadsheet.
This manual approach is slower but often yields highly targeted opportunities.
Step 3: Analyze Competitor Backlinks
Another strategy is to find broken links that competitors once had.
Steps:
- Use a tool like Ahrefs, SEMrush, or Majestic.
- Enter a competitor’s domain.
- Filter their backlinks by “Broken.”
- Export the list.
This reveals:
- Competitor pages that once earned backlinks but are now dead.
- Websites still linking to those dead competitor resources.
If you’ve created content covering a similar topic, you can pitch it as the perfect replacement.
Step 4: Identify Expired Domains with Backlinks
Sometimes entire websites disappear, leaving behind dozens or even hundreds of broken backlinks.
Tools to Use:
- Ahrefs Site Explorer: Search an expired domain and view its backlinks.
- ExpiredDomains.net: Find expired domains with backlink profiles.
- Wayback Machine: See what the old site looked like and what type of content it had.
If you have or can create content similar to the expired domain, you can contact linking sites and recommend your version.
Step 5: Audit High-Authority Sites in Your Niche
Some of the best opportunities come from auditing resource hubs like:
- Universities (.edu domains).
- Government websites (.gov domains).
- Nonprofit or industry associations.
These sites often maintain “Recommended Resources” pages but may not update them regularly. A single backlink from such a domain can significantly boost your authority.
Example:
If you run a cybersecurity blog and find that a .gov “Internet Safety” resource page links to a dead PDF, you can suggest your updated cybersecurity guide.
Step 6: Automate Broken Link Discovery
Manual searching is valuable, but at scale, automation saves time.
Tools:
- Ahrefs Broken Link Checker: Finds broken outbound links on a domain.
- Screaming Frog SEO Spider: Crawl large websites to uncover 404 errors.
- Dead Link Checker: Monitors entire websites for broken links.
- Hunter.io + Ahrefs: Pair broken link discovery with automated contact finding.
Set up workflows where these tools run scans regularly, alerting you when new opportunities appear.
Step 7: Prioritize Opportunities
Not all broken resources are worth pitching against. Evaluate opportunities by:
- Domain Authority (DA): Higher DA = more valuable backlink.
- Relevance: Does the broken link align with your content?
- Link Volume: If a dead resource has hundreds of backlinks, it’s a goldmine.
- Likelihood of Success: Some webmasters are responsive, others not.
Example of prioritization matrix:
- High DA + High Relevance + Many Backlinks = Priority 1.
- Low DA + Low Relevance = Ignore.
Step 8: Crafting Effective Outreach Messages
Finding broken resources is only half the battle. The other half is convincing webmasters to replace those broken links with your content. This requires thoughtful, personalized outreach.
Key Principles for Outreach
- Be Helpful First
- Don’t open with “link to me.” Instead, highlight the broken link to provide genuine value.
- Keep It Simple
- Webmasters are busy. Get to the point quickly and avoid fluff.
- Personalize the Message
- Mention their site name, the page URL, or even something specific you liked about the resource page.
- Position Your Content as a Solution
- Frame your resource as a helpful replacement, not self-promotion.
Example Outreach Template
Subject: Quick note about a broken link on your site
Hi [Name],
I came across your excellent resource page on [Topic] here: [URL]. While going through it, I noticed that one of the links to [Old Resource] is broken (returns a 404).
Since that resource is no longer live, I thought you might want to replace it. We recently published an updated guide on [Topic] that could be a good alternative for your readers: [Your Link].
Either way, thanks for the great resource — I’ve bookmarked it!
Cheers,
[Your Name]
This simple, polite approach typically gets better results than aggressive salesy outreach.
Step 9: Building Relationships with Webmasters
Link building should not be transactional. Think of it as relationship building.
- Engage on Social Media: Follow their work, share their content, comment thoughtfully.
- Offer Value Beyond Links: Provide feedback, suggest tools, or offer guest content.
- Keep Communication Open: If they don’t link right away, stay in touch for future opportunities.
Over time, a network of friendly relationships can yield far more backlinks than one-off cold emails.
Step 10: Advanced Pitching Strategies
Once you master the basics, you can scale broken link building with advanced tactics.
1. Replace High-Backlink Pages
When you discover a dead resource with hundreds of backlinks, create a dedicated piece of content to replace it. This tactic is called content recreation.
- Use the Wayback Machine to see what the old resource contained.
- Publish a fresher, more comprehensive version.
- Reach out to every site linking to the old page.
2. Multi-Option Outreach
Instead of suggesting only your link, give webmasters two or three replacement options (including yours). This makes your email more genuine and less self-serving.
3. Target Broken Links on Wikipedia
Wikipedia often has “dead link” tags.
- Replace those broken references with your resource (if credible).
- Even if the link doesn’t stay, many content creators use Wikipedia for sourcing and may pick up your link.
4. Leverage HARO and Journalist Outreach
Sometimes journalists unknowingly cite outdated or dead links. Offering your resource as an updated reference can land high-authority editorial backlinks.
Step 11: Common Mistakes to Avoid
Broken link building is powerful, but only when done right.
- Pitching Irrelevant Content
- If your content doesn’t align with the original resource, don’t pitch it.
- Over-Automation
- Automated outreach tools can scale but often come across as spammy. Balance automation with personalization.
- Ignoring Quality of Links
- Not all backlinks are worth pursuing. A few high-authority links beat dozens of spammy ones.
- Being Pushy
- If a webmaster ignores or declines your request, don’t hound them. Move on.
Step 12: Measuring Success
Tracking the ROI of your broken link building campaigns is crucial.
Key Metrics
- Outreach Conversion Rate: How many emails resulted in a live backlink.
- Domain Authority of Links Earned: Focus on quality, not just volume.
- Referral Traffic: Are those links sending visitors to your site?
- Organic Rankings: Monitor keyword improvements tied to new links.
Tools for Tracking
- Ahrefs / SEMrush: Backlink monitoring.
- BuzzStream: Outreach tracking.
- Google Analytics: Referral and organic traffic impact.
