What is the best alternative to SpamZilla?
It depends on why you buy expired domains. If you buy them for their backlinks, to build a niche site, a redirect or a private network, the closest alternatives are DomCop and Karma.Domains, which also sort names by third-party link metrics and spam checks. If you buy names to resell to end users or to use as a brand, the best alternative is a tool that values the name itself and catches it at the drop, which is what Domaining does.
Those are two different businesses that happen to shop in the same place. An SEO buyer pays for a domain's past. A reseller pays for what a startup or a small business will pay for the name next year. Most of the frustration people post about SpamZilla on forums comes from using a backlink tool for a resale job, then wondering why the high Trust Flow names will not sell.
This article is for US domain investors and brand buyers in that second group, plus SEO buyers who want to see where the tools really differ before they pay for another month.
What SpamZilla does well
Credit where it is due. SpamZilla pulls in thousands of expiring and auction domains a day and puts the link data an SEO buyer needs on one row: Majestic Trust Flow and Citation Flow, Ahrefs Domain Rating and referring domains, Moz Domain Authority, plus its own checks. The SZ Score runs from 1 to 100, where a low number means little sign of spam. SZ Drops counts how many times the name has dropped before, and SZ Parked flags a history of parking pages.
Those history checks are the part people pay for. A name that has dropped five times and spent years on a parking page is a poor SEO buy, whatever its Domain Rating says, and checking that by hand in the Wayback Machine takes far longer than reading a column. For a link buyer, that time saving is the product.
How much does SpamZilla cost?
Paid SpamZilla access starts at about $37 a month, according to recent independent reviews, with a small free view of around 25 domains to try it. Reviews describe higher tiers with more daily views, saved searches and API access for agencies, so check the current plan page before you budget. SpamZilla does not include the domains themselves: every name is bought separately at its auction house or with a backorder service.
SpamZilla entry plan
About $37 / mo
Finder and metrics only
Catching each name
$59 to $79
Per catch at DropCatch, SnapNames or NameJet
Domaining Starter
$49 / mo
Scored list plus 25 backorders included
The finder fee is rarely the big number. A buyer who catches four names a month at $59 each spends $236 on catch fees on top of the $37 subscription. That is the math that makes a plan with backorders included worth a look, and it is the same math we walk through in the DropCatch alternative review.
Where SpamZilla stops for a reseller
SpamZilla answers one question very well: is this domain's link history clean? A reseller needs three other answers, and SpamZilla is not built for them.
- What will an end user pay for it? Resale value comes from length, real words, the extension, commercial meaning and sold comparables. Backlinks barely move it. A two-word .com with no links at all can sell for thousands, and a name with DR 40 built from an old spammy blog may never sell.
- What is my ceiling? Without a value estimate there is no rational maximum bid, which is how investors end up overpaying in a public auction.
- How do I get it without babysitting every drop? A finder leaves you to place each order by hand at a different service. If you shortlist 40 names a week, that is the job that eats your evenings.
Domaining starts from those three. Every name on the daily list carries a 0 to 100 value score with the drivers spelled out, you set a maximum price per name, and backorder rules order matching names from each day's list for you. When two members want the same name, it goes to a private auction between them instead of an open one. The full scoring logic is on the domain valuation and appraisal tool page.
SpamZilla alternatives compared
An honest side by side, including where SpamZilla wins. We left out prices we could not confirm from a current source.
| Tool | Built for | What it scores | Buys the name for you | Weak spot |
|---|---|---|---|---|
| SpamZilla | SEO buyers | Majestic, Ahrefs, Moz metrics plus SZ Score, drops and parking history | No, buy at the source | Says little about resale value |
| DomCop | SEO buyers | Third-party link metrics with bulk filters | No, buy at the source | Same link-first view as SpamZilla |
| Karma.Domains | SEO buyers | Wayback content review and spam scoring | No, buy at the source | Newer, smaller data history |
| ExpiredDomains.net | Everyone | Raw lists with basic columns | No | You do all the filtering and valuing |
| Domaining | Investors and brand buyers | 0 to 100 resale value score with drivers | Yes, backorders by hand or by rule, 25 included from $49 a month | No Majestic or Ahrefs link metrics |

Is SpamZilla worth it?
Yes, if you buy expired domains for their backlinks every month. The spam and history checks save hours per name and keep you away from penalized domains, which easily covers $37. It is not worth it if you buy names to resell or brand, because the metrics it is best at barely predict what an end user will pay.
Plenty of investors do both kinds of buying. A sensible split is to keep a link tool for the handful of SEO buys and run the bulk of resale buying on a scored list with backorders. If you rebuild a caught name into a content site, you will also need the articles to fill it, and a tool that can write SEO blog posts gets the first pages live while the old backlinks still point somewhere useful.
A buying routine without SpamZilla
This is the weekly loop we would run for resale buying on Domaining. It takes about 20 minutes once the rules exist.
- Write two or three rules: extensions you can sell (.com first), a minimum value score, maximum length, no hyphens or digits, and a price cap per name.
- Let the rules backorder matching names from each day's expired domain names list. Check the matches once a day and remove anything you would not want to hold for a year.
- For the few names you would pay real money for, open the score drivers, compare sold prices and raise the cap by hand.
- When you win a private auction or a straight catch, list the name on the domain marketplace with a buy-now price and close the sale through escrow.
Try a rule on the sample list at the top of this page to see which names it would order, then compare plan limits on pricing. If you are weighing catchers as well as finders, the best domain backorder service guide covers DropCatch, SnapNames, NameJet and Dynadot side by side.
