The Ultimate Guide for 2024

Finding quality expired domains was a chore before I discovered SpamZilla. I am an affiliate of this software, but it’s only because I think it’s absolutely fantastic.

Here’s everything you need to know about this tool:

What is SpamZilla?

SpamZilla is a tool that helps you find and qualify expired and dropped domains.

You can use these domains for SEO purposes or for building niche websites.

There are a few ways to leverage expired domains for SEO.

First, acquire the expired domain and 301 redirect to your website.

There are a few different ways to execute this. You can do a straight 301 redirect to the homepage. I only recommend this method if the domain is hyper-relevant.

The second method is to create a page on your website dedicated to the topic of the expired domain. You would then 301 redirect the domain to the new page.

The goal of doing either method is to grow your site’s authority at a rapid pace. How so? Because you’re acquiring all the backlinks that the expired domain built.

I call this method The Merger Technique.

You can also use expired domains to build a network of websites that link to yours. This is called a private blog network, and it comes with substantial risk.

I won’t cover PBNs here, but it’s worth mentioning if you’re willing to take on more risk.

How to Use Spamzilla to Find Expired Domains

Using a tool like SpamZilla is the first phase of the expired domain acquisition process. The reason to even use such a tool is to streamline our efforts.

For example, you could use a free tool like, but they don’t have an efficient way to filter through thousands of domains. SpamZilla does.

Here’s how to begin your research:

Step #1: Integrate Ahrefs

If you have an Ahrefs (read Ahrefs review) account, I highly recommend you integrate it.

Step #2: Set your filters

Leveraging the filters will save you hours of time. Click the filter button.

I uncheck all Country TLDs because it can be difficult to register domains when you aren’t located in the host country.

You’ll need to adjust based on your location. For example, if you’re in Australia, you may want to keep the domain opportunities checked.

Majestic and Ahrefs’ Filters

I recommend setting “TF” to 10, “Ahrefs DR” to 10, and ”Domains” to 10.

These are just baseline filters, but you may need to adjust downward or upward.

Step #3: Start researching

The first type of domain I analyze is dropped domains. Under the “Expires” column, you’ll see “Available.”

This means that you can go to any registrar like GoDaddy or Namecheap and register the domain. That means you won’t need to get into a bidding war through auctions.

Now keep in mind: that these domains are often available for a reason. That said, it’s a good place to start because there are some diamonds in the rough that you can pick up.

But before I go any further, how do you qualify or disqualify domains?

How to Qualify Expired Domains

I’ve covered this process extensively in my expired domains guide. However, I’ll cover some important points here.

Go through this process (in this order) for every domain:

Look for relevance

Finding relevant domains with link profiles that are relevant to your target site is critical. Fortunately, you can use Majestic’s Topical Trust Flow metrics that are integrated within SpamZilla.

Scan the “Maj Topics” column to identify relevant opportunities. You can also set a filter so you only see relevant opportunities.

Examine the link profile

Once you’ve found a relevant opportunity, you must examine its link profile. You can do this natively within SpamZilla by clicking “See More Data” under the “SZ Score” column.

Then click the “Backlinks” (see how to get backlinks) tab, and you’ll see the link profile according to Majestic.

I recommend running the domain through Ahrefs as well to crosscheck.

So what are you looking for when you examine the link profile?

In short, you want the domain to have a natural link profile, with most of the links being editorial.

That means it’s not a good opportunity if the link profile is full of directory links.

However, if the link profile has links from the New York Times, you should get excited. One way to identify “quality” links in the profile is to filter and sort the links in Ahrefs. Choose “DoFollow” from the dropdown and then sort the links by DR.

This will show what high-authority links the domain has.

One other factor to consider is the anchor text. The anchor text should be unoptimized. It shouldn’t be full of exact match anchor text or foreign language anchors.

Audit the history

Once the domain has passed the relevance and link profile audit, it’s time to examine its history. In short, you want to ensure that it hasn’t been used for spam or SEO purposes in the past.

While you’re in SpamZilla, click on “Archive.”

This will show you how the domain has been used throughout its history. You should be skeptical if you see anything that doesn’t align with the domain’s original purpose.

Look for inconsistencies and move on to the next step if everything looks good.

See if it’s indexed

Ideally, the domain is indexed in Google, but it’s not always necessary. Sometimes domains get removed from Google’s index if they were previously redirected, have been out of commission, or have blocked Google crawlers.

Those are all acceptable reasons. However, an unacceptable reason is that the domain was removed because it’s been used for spam.

Fortunately, the previous steps should have helped you identify spam signals. So to see if the domain is indexed, click on “Index” inside SpamZilla.


If it’s indexed, you’re good to go. If it isn’t, you may want to continue your investigation further.

I recommend reading my expired domains guide for further qualification guidance.

Here’s the deal:

You need to take the process of qualification seriously. Treat these expired domains as if you were acquiring them as a real business.

In this case, you should use extreme due diligence to ensure it’s an excellent opportunity. Don’t speed through the process. The goal is to be 100% sure before investing in any expired domain.
