SpamZilla gives you a database of millions of expiring domains and leaves the vetting to you. SEODomain works the other way round: a short list of expired and aged domains we have already checked, each with its Ahrefs report and a direct link to buy it.
Membership from $24.50 a month, billed yearly. Cancel from your dashboard.
Every listing shows these before you pay anything:
Your first reveal is on us, once. The membership reveals every name, the full Ahrefs report and the purchase link.
The best SpamZilla alternative depends on what you are really paying SpamZilla for. If you want a bigger or cheaper research database, look at Karma.Domains or the free ExpiredDomains.net. If you are tired of filtering thousands of auction domains to find one clean one, a vetted marketplace like SEODomain removes that step: you see a short list of checked domains with their metrics and price, and you buy directly.
SpamZilla is a good tool. The question is whether you want a tool at all, or just the domain at the end of it.
Last updated September 2026.
Four ways to end up with an expired domain, compared on the things that decide the bill: what the subscription buys, who does the checking, and where the domain is actually purchased.
| SpamZilla | Karma.Domains | ExpiredDomains.net | SEODomain | |
|---|---|---|---|---|
| What it is | Search database of expiring and auction domains | Domain analysis platform with history reports | Free list of expired and deleted domains | Curated marketplace of checked domains |
| Price | From $37 a month; free tier shows 25 domains | $27.99 for 30 days, or credit packs | Free with registration | $49 a month, or $294 a year |
| Metrics shown | Ahrefs, Majestic, Moz, SEMrush, 70+ filters | SEO filters, Wayback content analysis, Karma spam score | Basic backlink and age data | DR, backlinks, referring domains, age, traffic, full Ahrefs report |
| Who vets the domain | You, helped by the SpamZilla Score (1 to 100) | You, with more history detail | You, entirely | Checked before it is listed |
| Where you buy it | At the auction or drop-catch service (GoDaddy, NameJet, DropCatch) | At the auction or registrar | At the auction or registrar | Direct purchase link at a fixed price, or an offer to our brokers |
| Price of the domain | Unknown until the auction closes | Unknown until the auction closes | Registration fee if it drops, auction price if not | Shown on the listing before you commit |
| Best for | Volume buyers and PBN builders who vet in bulk | Researchers who want deep history on a budget | Hobbyists with more time than money | Agencies and site builders who want one clean domain, fast |
Competitor prices come from their public pages and recent independent reviews as of September 2026. They change, so confirm on their sites before you subscribe.
We would rather you buy the right thing than the wrong thing from us. SpamZilla is the better fit in three situations.
If you are building a network and need a dozen or more domains a month, a database you can filter in bulk beats any curated list. Our catalogue is deliberately small.
Some SEOs enjoy digging through Wayback snapshots and anchor text at midnight. If that is you and your time is cheap, doing the vetting yourself is a fair trade.
A domain nobody has vetted yet can go for less at auction than a checked one on a marketplace. You pay for that discount with your own research and the risk of a bad pick.
Most people who leave SpamZilla are not unhappy with the data. They are unhappy with how many evenings it takes to turn that data into one domain they trust.
You look at a short list that has already been through a backlink, history and spam check, not at 350,000 new rows a day.
Every listing carries a fixed asking price in USD. No auction you might lose at 11:58 pm, no guessing what the final bid will be.
Members see the complete Ahrefs report for every listing, so you can judge the link profile yourself before you buy.
Think a price is high? Members send unlimited offers to our brokers on any listing and get a real answer.
An email reaches members the moment a new domain goes into the catalogue, before the public page shows it.
No contract. Cancel whenever you like and keep access to the end of the period you paid for.
The subscription is the smallest part of the bill. With any finder tool, the real cost is the checking you do after the filters: opening Wayback snapshots to make sure the domain was never a casino or a pill shop, reading the anchor text for over-optimization, confirming the links still exist, and then winning an auction against other people who ran the same filters.
An agency billing its time at $100 an hour does not need many evenings of that before a vetted domain with a fixed price is the cheaper route.
| Step | Finder tool | SEODomain |
|---|---|---|
| Shortlist candidates | You | Done |
| Check the Wayback history | You | Done before listing |
| Review the link profile | You | Ahrefs report included |
| Spot spam and redirects | You, with a score | Done before listing |
| Know the final price | After the auction | On the listing |
| Buy the domain | Bid and hope | Direct purchase link |
See every domain's DR, backlinks, referring domains, age, traffic and price. Names are masked until you reveal them.
A new account reveals one domain, once. The Broker membership reveals all of them, including the ones listed later.
Check the full link profile yourself. If the price looks high, send our brokers an offer.
Use the purchase link to buy at the listed price from the registrar or broker holding the domain.
The buyers who get the most out of SEODomain want a domain, not a research project.
A client wants results this quarter. A clean, relevant aged domain with a documented Ahrefs report is easy to justify on an invoice; a week of your team's research time is not.
You want to start publishing on a domain that already has topical links, instead of spending six months waiting for a new one to be trusted.
An aged domain with links from local US sites gives a new service-area site a far better start than a fresh .com with nothing pointing at it.
Fixed prices and broker offers make it simple to price a purchase against what you expect to resell or develop it for.
Google's spam policies call out expired domain abuse: buying an old domain mainly to host unrelated, low-value content that rides its past reputation. That is not what an expired domain is for. Pick one whose history matches what you plan to publish, then publish something genuinely useful on it.
That is also why topic fit matters as much as DR when you choose from our listings.
SpamZilla is worth it if you buy expired domains in volume and are willing to vet them yourself. For $37 a month you get a large filterable database with Ahrefs, Majestic, Moz and SEMrush metrics. If you need one or two clean domains a month, the hours spent filtering usually cost more than the subscription.
SpamZilla's paid plan starts at $37 a month, and reviewers report it covers up to 1,850 domain views a month. A limited free tier shows 25 domains. The subscription only pays for search access: the domain itself is bought separately at auction or from the registrar holding it.
SpamZilla is mainly a search tool, not a seller. It lists domains coming up at auction houses and drop-catch services such as GoDaddy, NameJet and DropCatch, and you place the bid or backorder there. On SEODomain, every listing already has an asking price and a direct purchase link.
It depends on why you are leaving. For a cheaper or deeper research database, Karma.Domains adds Wayback content analysis and a transparent spam score. For a free list, ExpiredDomains.net works if you have time. If you want to skip the research and buy a domain that has already been checked, a vetted marketplace like SEODomain fits better.
Yes, SpamZilla has a free tier, but it is limited to 25 domains and a reduced feature set, so it works as a preview rather than a way to buy regularly. SEODomain has no free plan either: a new account can reveal one domain once, and the Broker membership reveals the whole catalogue.
Yes, when the new site continues the domain's original topic and publishes genuinely useful content. Google's spam policies, updated in March 2024, name expired domain abuse: buying an old domain to host unrelated, low-value pages that ride its past reputation. A relevant, clean domain still gives a new site a real head start.
Yes. You cancel from your dashboard and keep access until the end of the period you paid for. Monthly membership is $49. Paying for the year costs $294, which works out to $24.50 a month, half the monthly rate for the same access.
$49 a month, or $294 for the year. Every listing, every Ahrefs report, every purchase link.
