Spamzilla Tutorial & Review

When it comes to buying good domain names, it isn’t just as simple as registering some fresh name that you just thought of. While yes, registering a new domain can be beneficial if you are starting up a new business and you have a great brand name to go with. However, if you plan on using any domains for things such as PBN’s or linking power then there are a lot of different factors you need to consider. You want to first off find a domain name that is relevant to you and your niche, then you need to check to see if anything suspicious or spammy has happened within the domains lifespan. Then you want to check that the domain metrics.

All of those checks are so important but can seem pretty overwhelming and time-consuming if you don’t have the right tools to help you out.

This is where Spamzilla comes in. This is a tool that helps bring all of these metrics together in one place. With some of their own stats and scores that can help you further determine which domains are best and which you should stay away from.


Before I explain how this tool works we first need to take a look at the price.

spamzilla pricing

There are 2 different pricing options with Spamzilla, free and paid.

In the free version, you will have basic access to the tool, allowing you to review up to 25 domains a month. This will give you some good metrics and can definitely help you gauge whether your domain names are spam free or not.

The paid version, however, has a lot more features for you to take a look at. The 2 key ones being a whole database of expired domains for you to look at and the ability to see a domains backlink profile. Spamzilla has millions of expired domains listed on the tool that is updated on a daily basis.

You can filter through all of these domains using loads of different metrics from some of the industry standard tools. On top of this, you can check up to 1850 of your own custom domains a month compared to the free version.


Now that we’ve got the pricing out of the way, it’s time to take a look at some of the tools we use.


The first thing you’ll notice is the huge list of domain names. But before I talk about them we first need to take a look at some of the options up at the top.

So as you can see there is a search bar at the top where you add any keywords you like, and Spamzilla will return results including your word.

So for example, I simply typed in “sport” here and a list of 8,941 domains are displayed all containing the word sport in one way or another.

Next, to the keyword search bar is a “+” button. This lets you add your own list of domains for Spamzilla to run its spam score against.

Once you click on the button you’ll see a box pop up like the one above, all you do is enter the domains that you want Spamzilla to take a look at and what you can also do is name the list of domains so you can save it for later use. In this example, I am just running a quick scan on a few well-known brands.

Once you send your list of domains to Spamzilla you’ll have a few options of what you’d like to do with them. First of all, select every domain in your list and click on the “start” button on the top left corner. This will run a check to see each of their spam scores.

So as you can see each of the domains have a result and an SZ score. The result is split into 3 different categories: spam, suspicious and clear.

The SZ (Spamzilla) score is a scale from 1 – 100 with the higher score meaning more spam has occurred.

In this example, it looks like “pepsi” has the cleanest domain name and websites “game” and “” have the highest level of spam.

To get back to the list of expired domains Spamzilla provides click on the “domains table in the top right-hand corner of the page.

Once you are back here the next button along the list allows you to view any lists that you have previously saved so you can revisit the domains in future and check to see how the spam score has changed.

Lastly, we have Spamzilla’s filters.

spamzilla filters

As you can see from the screenshot above, there are loads of different metrics here that you can narrow down and analyse with your list of domains. Like I had mentioned previously, Spamzilla pulls data from lots of industry tools and with the filters here you can decide which is most important to you.

You’ll also notice on the top right-hand side there is the option to save your filters, you can then load these up in future to save time going through each of these settings.


Now that we’ve had a look at the various settings you can go through it’s time to start looking through the domains.

Here I’ve simply applied a filter to see the sites with the lowest spam score.

The columns are split into very easy to understand sections:

Domain – This is the site in question, obviously it’s up to yourself what kind of domain name that you’d like to buy.

Source – The website that the domain is currently held for auction, clicking on this will take you the page where you can bid on the domain name.

TF (Trust Flow) – The majestic trust flow is a very important metric, this goes hand in hand with Citation flow.

CF (Citation Flow) – Citation Flow is another Majestic metric, the more even the ratio of these two the more likely it is a spam free domain.

Maj BL – This is the number of backlinks that majestic have found on the domain, the quantity here isn’t quite as important as the quality of the backlinks.

Maj RD – This is the referring domains that are pointing to your site. In other words, this is the number of domains pointing to your website.

Maj Topics – These are the different categories for a sites backlinks, it helps you understand what kind type of websites is linking to the domain.

Maj Lang – This is the language of the site’s backlinks, not the language of the domain itself.

Ahrefs, Moz, SEMRush – Spamzilla include metrics for all of these tools SEO tools. If you want to look further into their stats you will have to purchase a subscription to those tools directly but the data provided on Spamzilla is very useful to determine a domains quality.

Age – The age of a domain starts from when it was first registered. So for example, if a domain name was bought in 2010 then at the time of writing this the domain would be 9 years old.

SZ Score – Based on Spamzillas own metrics, they have a ranking system from 1 to 100 to determine how spam free the site is. Clicking on this metric will open up a new window, which gives you some more information.

What Spamzilla has done here is pulled data from both the way back machine and to let you see what kind of websites have been on the domain in the past. So instantly you can see with your own eyes if there is any sort of spam taking place. On the right, there is a little more information on the domain with the score displayed again.

The other feature here that is very useful is the “backlinks” section. This lets you take a look at 100 of the backlinks currently pointing to the site. While you can take a look at these on tools such as majestic and ahrefs you don’t actually need any of those tools to look at these links. As you can also see along the left-hand side there are loads more info available such as the anchor text of the links and what the word count looks like throughout the site’s history.

Opening the Spamzilla score is also just another way to view a lot of the data previously mentioned.

Google Index – You can see the number of pages that are still indexed on Google’s database

Date added – This is the date that the domain was added to Spamzilla

Price – This is the price of the expired domain on their current auction.

Expires – The date that the auction ends and the highest bidder wins the domain.


Spamzilla does a great job of vetting domain names, it gives you loads of data from the biggest and best SEO tools that would cost you way more to buy their individual subscriptions. On top of this, Spamzilla is adding newly expired domains to their own database every day which makes your job of searching for great ones even easier.

To get access to all of the tool’s features it does come with a cost, however, the free version is there essentially so you can try it for yourself. I would definitely recommend that anyone give Spamzilla a shot and if you’re serious about buying expired domains then paying for access to their huge database is worth the money.
