But it’s not entirely foolproof, and there’s some nuance to doing it well.

In this guide, you’ll learn how to get backlinks from broken link building.

But first, let’s cover the basics.

What is broken link building?

Broken link building is where you find a dead page with backlinks, create a similar page, then ask people linking to that page to link to you instead. The idea is that they’ll swap the link because they don’t want to send visitors to a broken resource.

Does broken link building still work?

It would be fair to say that SEOs are somewhat divided when it comes to this question.

In one video, Mark from Authority Hacker said:

I’ve come to the conclusion that it’s an almost pointless tactic, and you shouldn’t waste your time with it.

If you dig through the comments on that video, one stands out:

Let’s set the record straight:

Broken link building isn’t easy. Sometimes it works well. Sometimes it doesn’t.

Is this because there’s something inherently wrong with the tactic?

No. It’s because link building is hard to execute well—whatever tactic you use. The better you understand the tactic, the more likely you are to have success.

How to do broken link building

Broken link building is a four-step process.

1. Find broken pages with backlinks
2. Vet the backlinks
3. Create a replacement page
4. Do outreach

1. Find broken pages with backlinks

It’s impossible to find highly-linked broken pages without SEO tools. Even if you find dead pages manually, you’ll need a backlink checker to see how many links they have. You can use Ahrefs’ free backlink checker for this, but life is much easier with full access to Ahrefs.

Keep this in mind as we go through the tactics below. You’ll need Ahrefs for ¾ of them.

Here are the tactics:

1. Look for your competitors’ broken pages with backlinks
2. Look for broken pages about a topic
3. Look for broken links on competing websites
4. Look for broken links on resource pages (doable without paid Ahrefs)

a) Look for your competitors’ broken pages with backlinks

Many of your competitors will have at least some dead pages because everyone moves, deletes, and reorganizes content over time. If they forget to redirect old URLs when doing this, their backlinks will point to broken pages.

Here’s how to find dead pages on your competitors’ websites:

1. Go to Site Explorer
2. Enter a competing domain
3. Go to the Best by Links report
4. Filter for “404 not found” pages
5. Sort the report by Referring domains from highest to lowest

For example, there are 134 dead pages on Content Marketing Institute’s website, and some have backlinks from over 50 referring domains.

Your job is to sift through these pages for topics that make sense to create content about.

For example, the first page about “what is content marketing” makes sense for us because we have an entire blog category about content marketing. It’s the kind of topic we want to build links to.

If you don’t find a relevant broken page on one competitor’s website, repeat the process for others.

TIP

If you’re unsure who your competitors are, enter your domain into Site Explorer and go to the Competing Domains report. This shows other websites ranking in Google for the same keywords as you.

b) Look for broken pages about a topic

Broken link building has traditionally always been about the method above. The disadvantage of this method is that you limit yourself to finding opportunities on a handful of sites.

The ideal solution to this problem would be searching the web for broken pages with backlinks about a particular topic. The only tool we’re aware of that allows you to do this is Ahrefs’ Content Explorer, a searchable database of billions of web pages.

Here’s how to use it to find broken pages about a topic:

1. Enter a broad topic
2. Switch the search mode to “In title”
3. Hit search
4. Filter for broken pages only
5. Filter for pages with at least 20 referring domains

In the example below, there are 188 broken pages with at least 20 backlinks about content marketing:

To confirm a broken page, click the title to open it in a new tab.

TIP

Eyeball the “Page traffic” column to find pages that are more likely to have high-quality backlinks. If the page used to have traffic, its backlinks might have been helping it to rank.

If the page never had traffic, the backlinks might not be great.

c) Look for broken links on competing websites

Most websites frequently link to pages on other sites, and some of these will break over time. That means your competitors are likely to link to broken pages.

Here’s how to see broken pages your competitor is linking to:

1. Go to Site Explorer
2. Enter a competing domain
3. Go to the Broken Links report

For example, robbierichards.com is linking to 32 dead pages:

To see which have the most referring domains, export the report, paste the broken URLs into Ahrefs’ Batch Analysis tool, and sort by total referring domains.

Here are a few potential broken link building opportunities in the screenshot above:

• Google’s discontinued mobile-friendly test tool: 2,654 RDs
• SEJ’s guide to the Google Hummingbird algorithm: 462 RDs
• Chatmeter’s list of local SEO stats: 276 RDs

d) Look for broken links on resource pages

Resource pages curate and link to resources on a particular topic. They’re a good source of broken pages with backlinks for two reasons:

1. People rarely update them, so they often link to dead resources.
2. They list helpful resources which often have links from many other sites.

To find resource pages in your industry, use one of these Google search operators:

• KEYWORD intitle:resources inurl:links.html
• KEYWORD intitle:links inurl: resources.html
• KEYWORD inurl:resources intitle:resources

For example, here’s how we might search for resource pages about link building:

Then you need to check for broken links on these pages, which you can do for free with Ahrefs’ SEO toolbar.

1. Visit the page
2. Click the toolbar icon
3. Go to the “Links” tab
4. Click “Check status”
5. Filter for broken links only

To see the total backlinks to these pages, export the list of URLs and paste them into Ahrefs’ Batch Analysis Tool.

2. Vet the link prospects

Many people jump straight to creating a “similar” replacement page after finding a dead page with backlinks. This is a mistake for two reasons:

1. Your broken page may not have any good backlinks. In which case, there’s no point pursuing the opportunity or creating a replacement page.
2. You need to understand why people linked to the dead page to create a replacement page. This is how you keep your content and outreach in sync, which leads to higher success rates.

You can figure out both things by vetting the page’s link prospects.

Here’s the process in a nutshell:

a) Check link quality

If a broken link-building opportunity is unlikely to lead to high-quality links, it’s pointless pursuing it. So the first step is a quick spot check to see whether the dead page has desirable backlinks.

Here’s how to see a page’s live backlinks:

1. Go to Site Explorer
2. Enter the dead page’s URL
3. Go to the Backlinks report
4. Set the grouping mode to “One link per domain”
5. Set “Show history” to “Don’t show”

Then you can eyeball the report to get a sense of backlink quality.

You can do this by reviewing each link manually, but that’s inefficient for a spot check. It’s quicker to filter the report for links with attributes that tend to align with quality.

Everyone’s criteria will differ slightly here, but these four filters are a helpful place to start:

• ‘Dofollow’ links only. This excludes most low-value links such as those from directories, forums, and blog comments.
• Exclude subdomains. This excludes links from places like blogspot, which are often low-quality and spammy.
• DR 5+. This excludes links from very low-authority websites.
• Domain traffic: 20+. This excludes links from websites with little to no traffic.

For example, if we add these filters to the backlink report for the page above, the number of backlinks drops from 100 to 29:

That’s because the dead page has many desirable links, such as this one from celebanswers.com:

But it also has many low-quality and spammy links like this one:

It’s up to you to decide whether a broken page has enough desirable links to make creating a page and doing outreach worthwhile.

b) Check link reasons

Understanding why your broken page got links helps you add points that allow you to create compelling outreach angles. This is crucial for improving the link success rate for your campaign, so the next step is to eyeball the filtered report for link reasons.

Here are the two broad types of link reasons you’ll see:

• General links are where people recommend the resource as a whole. You can’t see why they linked to that specific resource from the link’s context.
• Deep links are where people recommend a resource for a specific reason. You can see what that reason is from the link’s context.

Here’s an example of a general link to a broken page about calculating your net worth:

You can see that although they recommend the resource, it’s impossible to tell why from the link’s context. The anchor is “here’s an amazing post.”

There’s not much you can learn about creating a “better” page from these kinds of links.

You can learn more from deep links like this:

This time it’s obvious why they recommended the resource: it explains how to grow your net worth.

We can confirm this by looking at how the page used to look in the Wayback Machine:

Identifying deep links helps you create a compelling replacement page, so note them down alongside how many people link for the same reasons. Search the Backlinks report for relevant ‘footprints’ in the anchor or surrounding text to find this.

For example, we can search this page’s backlinks for words like “increase,” “grow,” or “improve” to see if this advice led to other links.

It looks like it did:

Here’s what our final notes might look like for this page:

3. Create a replacement page

Now you know why people linked to the dead page, it’s time to create a suitable replacement.

Let’s go through how to do that in three steps.

a) Create a rough outline

Although you don’t want to copy the dead page word for word, you do want to create something similar. This means crafting a piece that fulfills the same purpose and talks about similar things.

You can get a better sense of what the dead page discussed using the Wayback Machine.

For example, this page explains how to calculate your net worth in three steps, gives a few example calculations, and has tips on how to improve your net worth over time:

If you were pursuing this broken link opportunity, you’d want to use a similar outline.

Here’s what that might look like:

• H1: Net Worth Explained: How to Calculate and Improve It Over Time
  • H2: What is Net Worth?
  • H2: How to Calculate Your Net Worth
    • H3: Step 1. Do x
    • H3: Step 2. Do y
    • H3: Step 3. Do z
  • H2: Example Net Worth Calculations
    • H3: Example 1: x
    • H3: Example 2: y
    • H3: Example 3: z
  • H2: How to Track and Improve Your Net Worth
    • H3: Tip 1: Do x
    • H3: Tip 2: Do y
    • H3: Tip 3: Do z

b) Bake in linkable points

Remember the work you put into vetting link prospects for deep recommendations? Now’s the time to add them to your content so that your outreach angles make sense.

In this case, we covered most of these in the basic outline.

c) Find other ways to improve it

Most of the links to your dead page are likely to be general links. In other words, they’re people referencing the content for no clear reason.

You can’t do much to tailor your content for these people because you don’t know what they liked about the original piece. But you can make overall improvements.

For example, adding a template would probably improve our piece on calculating net worth.

Improving the content allows you to strengthen your value proposition to general linkers by adding a “why”:

• Without improvement: you have a dead link > here’s a replacement
• With improvement: you have a dead link > here’s a replacement > here’s why it’s a good replacement

Here are a few simple ways to improve content:

• Simplify: Make it more accessible and easier to understand.
• Visualize: Demonstrate concepts with graphics.
• Templatize: Add a plug-and-play template.
• Rectify: Fix issues with accuracy.

4. Do outreach

Outreach is where you pitch your replacement resource to those linking to the dead page.

This is usually done in one of two ways:

• Shotgun outreach. You send the same email to everyone with no personalization.
• Sniper outreach. You send unique, personalized emails to everyone.

Both of these approaches have their pros and cons.

Shotgun outreach is a pure numbers game. Conversion rates will be low, but you’ll get some links with enough prospects. It’s also risky. You can quickly burn bridges and get your domain blocked.

Sniper outreach converts better but takes more time and effort. You can easily spend a whole day sending a dozen emails.

Given the steps we’ve gone through so far, we recommend a hybrid approach.

Here’s how this works:

Instead of sending a unique or identical email to everyone, you segment prospects and create a personalized template for each group. This is why we spent some time identifying general and deep links. The way you target them should be different.

Pitching deep linkers

Each segment of deep linkers deserves a unique template.

For example, we have three segments for the net worth page:

1. People referencing advice on growing your net worth
2. People referencing the definition of net worth
3. People referencing how to calculate net worth

Here’s a simple template for the first segment:

Hey [Name],

Just came across your post on [Topic] and saw that you recommended advice on growing net worth from [Dead page author].

Looks like that page no longer works.

Not sure if you’re still updating older posts, but if you are, my guide expands on that advice and gives a few extra tips.

Here’s where I found the link on your page:

Here’s one for the second segment:

Hey [Name],

Just came across your post on [Topic] and saw that you recommended this process for calculating net worth from [Dead page author].

Looks like that page no longer works.

Not sure if you’re still updating older posts, but if you are, my guide has a similar process but includes more detail on how to estimate the value of your assets and debts (super important for an accurate calculation!).

Both of these are pretty typical and could use a bit more creativity. But hopefully, you can see how creating personalized templates like this can potentially improve the results of your broken link-building campaign.

Pitching general linkers

As there’s no clear reason why these people linked to the dead page, you can only send them a generic pitch. This should follow the same formula as with deep linkers. The difference is that the value proposition will be a generic one.

You can use the improvements you made to the dead page for this.

Here’s an example template for our page:

Hey [Name],

Just came across your post on [Topic] and saw you recommended this guide to calculating net worth from [Dead page author].

Looks like that page no longer works.

Not sure if you’re still updating older posts, but if you are, my guide explains a similar process and includes a free template to make life easier.

Here’s where I found the link on your page:

A few other reasons why I think my guide is better (completely biased, of course):

• More details on estimating the value of assets and debts
• Extra tips for growing net worth
• Flowchart to create a custom growth plan

No pressure. Just thought it might be useful 🙂

Josh

This template is the best we can do for general linkers because we don’t know why they linked to the original page.

Final thoughts

Link building tactics are just streamlined ways of finding link prospects with a reason for contact. In broken link building, the reason is that they have a dead link on their site. In the skyscraper technique, the reason is that you have a “better” page. In other techniques, it’s something else.

No technique will work well without a strong value proposition. That’s why we recommend using custom outreach templates for different segments of prospects linking to the dead page.
