SpamZilla is the tool most SEOs name first when they talk about finding expired domains. This review is for the person about to pay for it: what one row of data tells you, how far the SZ Score can be trusted, what the customer reviews say, and what a usable domain costs once the tool has done its part.

The short answer
SpamZilla is a legitimate and useful expired domain finder that costs $37 a month on its Standard plan, with a Free plan capped at 25 domain reviews. Its SZ Score, a 1 to 100 spam rating where lower is cleaner, is a fast first filter but still lets the odd spammy domain through. It does not sell domains, and its Trustpilot score is 3.1 from only 7 reviews. Pay for it if you buy often. Buy a vetted listing if you need one domain.
Every domain in the database sits on one row with its own spam numbers, the main backlink metrics from three providers and an icon for where it is being sold. Filter on any of them, more than 70 ways in total, and save a filter to get new matches by e-mail each morning.
That layout is the product. It turns an afternoon of pasting names into three SEO tools into a sorted list you can scan in minutes, and it is why people who buy every week stay subscribed.
Read the score as a sorting tool. A high number is a reliable no. A low number is a maybe that still needs an evening with the anchors, the referring domains and the Wayback history. Our expired domains with backlinks page lists the checks we run before a name is allowed into the catalogue.
Standard is the only paid plan. It opens the whole database of expired, expiring and auction domains, runs the spam check on every row, shows the backlink metrics, unlocks the 70 plus filters and the daily e-mail, and gives you 1,850 credits a month to run SpamZilla's checks over lists you bring yourself, such as an export from an auction house. The Free plan stops after 25 domain reviews.
There is no annual discount and no agency tier on the pricing page we read in September, and the page blocks automated reads, so check it yourself before you pay. Our SpamZilla pricing breakdown goes line by line, and SpamZilla vs DomCop shows how $37 a month compares with DomCop's $816 to $1,416 a year.
Once you have a shortlist, export it rather than retyping names. If your bids, renewals and site plans live in other tools, you can sync the exported shortlist into the apps you already use so nothing gets lost between the finder and the auction.
Trustpilot, October 2026
3.1
out of 5, from 7 reviews
Seven reviews is too few to call a reputation, and none were written in the last twelve months. Still, the pattern is worth knowing before you enter a card. The two five-star reviews praise quick, knowledgeable support and a fair price. Four of the five one-star reviews are about money: charges the reviewer did not expect, refund requests that went nowhere, or an account disabled after payment.
SpamZilla answered six of the seven. Its replies say refunds are given for valid reasons, that accounts are disabled only when data scraping is detected, and in one case that its payment logs did not match the reviewer's story. We cannot judge who is right in any single dispute. The practical lesson is plain: note the renewal date, cancel from the account when your search ends, and keep the confirmation.
The subscription is the line everyone quotes and the smallest one in the total.
| Line | SpamZilla plus an auction | SEODomain listing |
|---|---|---|
| Access to the data | $37 for each month you search | $49 for one month, or $294 for the year |
| Price of the domain | The auction close or backorder fee, unknown in advance | Fixed and shown on the listing |
| Who reads the backlinks | You, starting from the SZ Score and the top 100 links | Done before listing, Ahrefs report handed to members |
| Chance you end with nothing | Real: outbid, not caught, or renewed by the owner | None once you pay the listed price |
| Time from decision to owning it | Days to weeks, set by the auction or drop date | Usually 24 to 48 hours |
For a frequent buyer the left column wins. The data is cheap, the pool is huge, and a patient bidder lands names for far less than any curated list asks. The right column is what a higher price pays for: the reading is done, the number is fixed, and nobody can take the domain off you in the last five minutes of an auction. The listings in our catalogue today are priced from $1,800 to $2,400 with Ahrefs DR from 42 to 51, and that price is the whole price of the name.
SpamZilla rows often point at DropCatch or GoDaddy. If those are the auctions you keep losing, our DropCatch alternative and GoDaddy Auctions alternative pages show what changes when the price is set before you start.
SpamZilla is worth $37 a month for someone who buys expired domains several times a year and can read a backlink profile. The SZ Score clears out obvious junk fast, which saves hours. It is poor value if you need one domain, because the plan bills while you hunt and you still have to win the name somewhere else.
Yes. SpamZilla is a working expired domain research tool that has been sold for years at $37 a month, and well-known SEO reviewers use it. Its Trustpilot page is thin: 3.1 out of 5 from 7 reviews, five of them one star and mostly about billing and refunds. The company replied to six of the seven.
The SZ Score is SpamZilla's own spam rating from 1 to 100, where a lower number means a cleaner domain. It comes from a proprietary check of the domain's history and links. Clicking it opens snapshots, the sources of up to the top 100 backlinks and any flagged messages, which is where the real reading starts.
Accurate enough as a first filter, not as a final verdict. Reviewers who like the tool still report spammy domains scored as clean, and the score cannot judge whether a domain's links fit your niche. Use it to throw out the worst candidates, then check anchors, referring domains and archived content yourself before you bid.
There is no time-limited trial. The Free plan lets you review 25 domains and then stops, which is enough to see the interface and the SZ Score but not enough to find a domain. Anyone shopping in earnest moves to the $37 Standard plan, which unlocks the full database and 1,850 credits a month.
Yes. Standard is a monthly subscription with no annual contract, so you can stop it when your search ends. Cancel from the account before the next renewal date and keep the confirmation, since most of the one-star reviews on Trustpilot are about charges after the buyer thought the plan had ended.
If you need a single domain rather than a research tool, a vetted marketplace is the closer fit. SEODomain lists expired domains that already passed the history and backlink checks, shows Ahrefs DR, referring domains and a fixed price on each listing, and gives members the Ahrefs report and a direct purchase link.
SpamZilla earns its reputation as a first filter. The SZ Score, the drop and parking counts and the filters cut a list of thousands down to a short set worth reading, and $37 a month is easy to justify for anyone who bids every week.
It is still a finder. The final judgment on the links, the auction and the transfer all happen after SpamZilla hands over, and that is where most of the cost and risk of an expired domain sits. If you want those parts finished, with the Ahrefs report as proof, a vetted listing costs more per name and far less per evening.
