Spamzilla is a cloud-based application that scrapes various auction and expired domain lists and analyzes each domain using its own proprietary software to weed out domains that have been abused or misused previously.
They do this first by scraping Pending Delete, Fully Expired, GoDaddy Auctions, GoDaddy Closeouts, NameJet, and SnapNames auctions and then using Majestic and Ahrefs API’s to get the metrics, backlinks and anchor text of each domain.
Then they run each domain in the archive.org’s Wayback machine and Screenshots.com to see if the domains may have been used as PBN’s or some sort of spam site in the past.
They also look for excessive 301 redirects which can be a red flag for abuse.
Spamzilla then comes out with a “Spamzilla score” of 1 to 100. 1 being super clean, 100 being definitely spammed.
Most domains lie somewhere in between the two, and I haven’t seen a domain get lower than a 3.
A look inside Spamzilla
What’s a good Spamzilla Score?
The “safe” Spamzilla score is 20 and below. From using Spamzilla extensively over the past couple of weeks (and snapping up some great domains at the same time) I agree with this score and my default setting for filtering out domains is usually set at 20 and below.
However, there have been times where I have spotted a domain that was obviously spammed with a score of less than 20. I have also seen domains that look a little spotty, but are overall clean that have a Spamzilla score of above 20.
The Spamzilla interface can seem a bit overwhelming at first, but it is actually very easy to use and intuitive after you spend some time with it.
When you first open Spamzilla you are given a database as above. Here is a breakdown of what all the columns mean:
Domain: The website name that is available to buy
Source: The source where you can buy the domain, can be expired and free to pick up anywhere, or auction which needs to be purchased from an auction website
TF: Majestic’s Trust Flow a good metric to look at to see the “Trustworthiness” of a website, the higher the number the better
CF: Majestic’s Citation Flow, you want the TF and CF to be in a similar ratio – if the CF is higher than the TF it is likely to be spam
Maj BL: Majestic’s Back Links, usually the more backlinks a domain has the better. However, sometimes too many backlinks mean the domain has been spammed.
Maj RD: Majestic’s Referring Domains, again the more referring domains the better. But too much can sometimes mean spam.
Maj Topics: Majestic’s Topics – a good quick way to see what niche a domain to find topically relevant domains
Site Lang: Main language the backlinks are in.
Moz DA: Moz’s Domain Authority – the most popular metric used to determine overall domain strength, however, can be easily manipulated.
Moz DA: Moz’s Page Authority – how powerful the main page of the domain is. Similar to Ahref’s UR metric
Age: Age of the domain from the time it was registered. However it could have been dropped at any point or not active during that time.
SZ Score: The money metric, this is Spamzilla’s spam score, the lower the better.
Opening Up The Filter
The first thing you want to do is hit the filter button at the top. This will bring up the page where you can sort the millions of available domains.
I am not going to go through each metric here, but will give you some recommendations based on what you are looking for.
If you want to find good expired domains it is best to keep your expectations low. So I would set the following filters:
SZ Score: 0 to 20
Tip: Even though Spamzilla does a good job filtering domains, you’re going to have to still have to take a good second look at expired domains since they are usually spammed. That means looking closely at domain snapshots and running the domain in ahrefs to see if it was ranking for junk keywords like “nike air max shoes”.
If your willing to spend a bit of money, you can set your sights a bit higher here. These are the filters I use:
SZ Score: 0 to 20
Auction Ends: Current day or One day in Advance
Pro Tip: If you are bidding on auction domains, it is best not to bid on them too early. This causes the price to raise quickly. The pros wait until the last 5 minutes to bid on domains, this keeps competition low and allows you to sometime swoop in and grab domains at a super cheap price
How To Screen Domains with Spamzilla
Now that you have whittled down the list of domains to ones that have some link juice and aren’t completely spammed (hopefully) your going to want to do your due diligence and take a deeper look at the domains.
To do this your going to want to click on the Spamzilla score:
Here it brings up an awesome overview of the Wayback machine’s history. This seriously beats going through each year and it saves a ton of time and is the most important feature in screening a domain.
Be sure to go through each screenshot, because one small screenshot can mean the difference between a good domain and a bad one.
You can also easily view the domains backlinks, redirects and even the domains historical wordcount and drops. Each one of these views can mean a domain was used either as a PBN or for spam.

Domcop vs Spamzilla Pricing
Domcop is not a cheap service. It comes in 3 different price points:
- Newbie Plan – $56 / month
- Power Plan – $98 / month
- Guru Plan – $184 / month
However if you pay for the yearly plan, this reduces the price by 40%.
Spamzilla on the other hand only has one price point: $37 / month and it comes with it’s Spamzilla screening software, which saves you a whole lot of time when buying domains
What about the Features?
Sure Spamzilla wins out on price, but what about the other features?
Well it appears that Ahrefs not in DomCop anymore, but SpamZilla does have Ahrefs when connecting it to your Ahrefs account.
Spamzilla also shows DNS History and domain drops count (how many times a website expired) which is useful to know when manually checking if a domain was used as a PBN.
Spamzilla features Historic snapshots from Archive.org and Screenshots.com and Domcop does not. Spamzilla has a WayBack Exporting tool, which allows you to download a website from Archive.org quickly and easily.
Domcop really doesn’t match up well to Spamzilla…
Is Spamzilla Worth It?
If you are serious about buying domains and were considering Domcop or Register Compass than you can’t go wrong with Spamzilla.
It does everything it promises to do, and it does it cheaper than similar programs with a lot less features.
Spamzilla is constantly adding new features and working with more auction domain companies, so I feel like it is only a matter of time before they raise their prices.
