Broken Link Building: How to Find Dead Links & Earn Replacements

Quick answer: what is broken link building?

Broken link building is the process of finding dead external links on relevant websites, identifying what the missing resource used to provide, and suggesting a current useful replacement.

The tactic works because you are helping the publisher fix a real user-experience problem. But it only works well when the replacement genuinely matches the broken resource. Sending any vaguely related URL because a page contains a 404 is not useful outreach.

Why broken link building still works

The web constantly changes. Pages are deleted, domains expire, companies rebrand and URLs move without redirects. Resource pages and older articles can accumulate dead links over time.

For the publisher, a broken outbound link reduces usefulness. For the marketer, it reveals an existing editorial slot where the writer previously believed an external source was valuable.

That does not mean the publisher owes you the replacement. Your job is to provide a source that makes the page at least as useful as it was before.

Three broken link building models

1. Prospect-first broken link building

Find relevant sites, crawl them for broken outbound links, then look for replacement opportunities.

This is useful when you already have a tightly qualified publication list.

2. Resource-first broken link building

Start with a linkable asset you want to promote. Find dead resources that covered the same subject, then identify pages that linked to those dead URLs.

This is often more scalable because one defunct resource can reveal many prospects.

3. Competitor lost-link replacement

Monitor competitor links that disappear because a competitor page was deleted or moved. When the linking page still exists, offer a current relevant alternative.

Step 1: choose a replacement-worthy asset

Broken link outreach is easier when your site already has something useful.

Good replacement assets include:

• updated guides;
• research;
• statistics pages;
• calculators;
• templates;
• glossaries;
• tools;
• checklists.

A generic homepage is rarely the best replacement for a dead informational source.

Step 2: find broken external links

You can use crawlers, browser extensions, backlink tools or manual inspection.

Common workflows include:

• crawl a resource page and export 4xx external URLs;
• search a competitor’s lost backlinks;
• find expired resources with many referring domains;
• inspect older best-resources pages in your niche.

The broken status should be verified. A temporary server error is different from a permanently removed resource.

Step 3: investigate what the dead page used to contain

This is essential.

Use web archives, old anchor text, surrounding copy and other linking pages to infer the original purpose. Was it a research report? A tool? A definition? A PDF? A product?

Your replacement should satisfy the same user need.

If the dead page was a detailed government dataset and you pitch a 500-word opinion post, the substitution is weak even if the topic is similar.

Step 4: find pages linking to the dead resource

Once you have a genuinely dead resource with a useful replacement opportunity, use a backlink index to find its referring pages.

Filter by:

• topical relevance;
• live/indexed page;
• publication quality;
• language and geography;
• whether the broken link is still present;
• whether the article is actively maintained.

This becomes your prospect list.

Step 5: qualify the page before contacting anyone

A broken link does not automatically make the page valuable.

Read the page and ask:

• Does the article still serve readers?
• Is the publication legitimate?
• Is the broken citation relevant to our resource?
• Would our link improve the exact section?
• Is the author or editor identifiable?

Step 6: improve the replacement if necessary

Sometimes your existing asset is close but not good enough. Update it before outreach.

Add missing data, current examples, clearer sourcing or the specific feature the dead page offered. Broken link building works best when the editor can make a simple quality-preserving swap.

Step 7: find the right contact

Contact the person most likely to maintain the page: author, editor, content manager or webmaster depending on the publication.

Avoid emailing five people at the same company simultaneously.

Step 8: write the outreach email

A strong broken-link email is short because the value proposition is obvious.

Subject: broken resource in your [topic] guide

Hi [Name],

I was reading your [article title] and noticed the link to [old resource] currently returns a 404.

If you’re updating the page, we have a current resource covering the same point here: [URL]. It includes [one useful differentiator].

Either way, I wanted to flag the broken link while I had the page open.

Best,
[Name]

Do not pretend you stumbled across the page if you clearly ran a broken-link campaign. You can be concise without being deceptive.

Step 9: follow up once, if appropriate

One follow-up is usually enough. Add useful context rather than writing "just checking."

For example: mention that you updated a data point, added a downloadable table or found another broken link on the same page.

If there is no response, move on.

Step 10: verify the live result

When a link is added, record:

• live linking URL;
• destination URL;
• anchor text;
• link attribute;
• publication date or update date;
• acquisition method;
• referral traffic if available.

Finding dead resources with many links

A scalable approach is to find discontinued tools, old studies, expired domains and deleted guides in your niche that still have referring domains.

Good candidates often come from:

• old industry reports;
• acquired companies with retired content;
• discontinued products;
• university resources moved during redesigns;
• defunct associations;
• expired statistics pages.

The best opportunity has two characteristics: the old resource had meaningful backlinks, and you can provide a genuinely equivalent or better source.

Broken link building with resource pages

Resource pages are especially suitable because they exist to curate external links and often contain older URLs.

You can combine tactics:

1. find a relevant resource page;
2. identify a dead outbound link;
3. suggest your resource as a replacement;
4. optionally flag other broken links to be helpful.

Broken link building with competitor research

Monitor competitor pages that once attracted many links but are now removed, redirected incorrectly or outdated.

If a competitor retires a popular study, create your own original current research rather than copying the content. Then approach the publishers that need a current source.

How to prioritize broken link prospects

| Factor | Question | |—|—| | Relevance | Does our resource satisfy the same need? | | Page quality | Is the linking page useful and maintained? | | Publisher legitimacy | Would we want to be cited here anyway? | | Edit likelihood | Does the site update older content? |

A high-authority page that has not been touched in ten years may be less actionable than a smaller publication with active editorial maintenance.

Broken link building mistakes

Suggesting a poor replacement

The replacement must match the old resource’s function, not just its keyword.

Pitching irrelevant high-DR pages

Broken does not mean relevant.

Failing to verify the 404

Temporary errors and geo-blocking can produce false positives.

Sending generic mass emails

The outreach should name the page, broken resource and reason your replacement fits.

Creating a copy of the dead page

Recreate the user value, not the copyrighted content.

Is broken link building safe?

Broken link building is fundamentally an outreach method. The risk depends on how it is executed. Helping a publisher replace a dead resource with a useful relevant source is very different from purchasing large numbers of manipulative links.

Google’s spam policies still apply to any commercial link arrangement intended to manipulate rankings.

How many broken link emails should you send?

There is no universal conversion rate worth promising. Results depend heavily on prospect quality, freshness, asset match, deliverability and the publisher’s willingness to update old content.

Track your own funnel:

• qualified pages;
• contacts found;
• emails delivered;
• replies;
• links earned;
• referral traffic.

Then improve the weakest stage.

Frequently asked questions

What is broken link building?

It is the process of finding dead external links on relevant pages and suggesting a current useful resource that can replace the missing source.

What tools can find broken links?

Crawlers, backlink indexes and browser extensions can all identify 4xx URLs. The important step is manually verifying the broken page and editorial context.

Do I need to recreate the old content?

No. You need to satisfy the same reader need. Your resource should be original and can be better or more current than the old page.

Can broken link building work for service pages?

Usually informational assets are easier replacements. A service page works only when the original citation was genuinely commercial or product-oriented.

Final takeaway

Broken link building works when you approach it as content maintenance assistance, not a loophole for inserting any URL into an old page.

Find dead resources with real editorial context. Understand what the missing source provided. Offer an original replacement that makes the article useful again. That gives the publisher a reason to update the link and gives you a defensible backlink opportunity.
