In this article, we'll look at how Karma.Domains stands apart from Spamzilla and why so many specialists are transitioning to this new platform.
Domain History Analysis via Wayback Machine
Spamzilla provides general data on site history, but Karma.Domains focuses specifically on content analysis.
Its proprietary analysis tool, based on snapshots from the Wayback Machine, allows users to:
- show only snapshots that are meaningfully different, avoiding duplicates and helping users clearly see real content changes over time
- detect toxic themes (pharma, gambling, p*rn, etc.)
- track sudden changes in content, topics, and languages
- identify doorway pages and hidden redirects
- verify changes in ownership and hosting
Karma Score: A Transparent Spam Rating System
Spamzilla Score also considers past content quality, but it doesn’t explain why a certain score is given or how it was calculated. Karma Score prioritizes transparency: you can see the exact reasons for each score and access detailed data, enabling more informed domain decisions. The worse a domain’s “biography,” the lower its Karma Score.
This helps users avoid purchasing domains with toxic or questionable pasts—something often overlooked by other services.

Support for Major Auctions and Daily Updates
Karma.Domains processes 400,000+ domains per day from:
- GoDaddy
- DropCatch
- NameJet
- Sedo
- Dynadot
- Namesilo
The service also supports dozens of ccTLDs and gTLDs, including .com, .net, .org, .co, .de, .io, and many more.
Expired Domains Available for Immediate Registration
A standout feature is the section with expired domains, updated daily with thousands of curated domains featuring real history and strong backlink profiles. All domains are additionally screened against antivirus databases to weed out potentially harmful assets.
All domains in this section are available for immediate registration, with no need to participate in auctions.
Special attention is given to including many national TLDs, such as .es, .de, .fr, and others — enabling users to find high-quality expired domains not just globally, but within local markets too.
SEO Filters and Metrics
The domain filtering tool in Karma.Domains greatly expands search and analysis capabilities. Unlike Spamzilla, where content filters are limited, Karma.Domains provides a flexible filter interface, including:
Core Filters:
- Select domain zones (gTLDs, ccTLDs)
- Keyword search in domain names and categories
- Include or exclude numbers and hyphens
- Domain name length range
- Karma Score (a unique metric for content history quality)
Majestic:
- Trust Flow, Citation Flow, number of backlinks and referring domains
- Site language and topics from Majestic Topics
- Total backlinks and referring domains
SEMrush:
- Authority Score, traffic, backlinks
- Backlink URL, target, anchor text
- Keywords, top organic pages, competitor domains
Wayback Machine (Web Archive):
- Unique ability to search domains by content in Wayback Machine snapshots
- Filter by number of changes (WA Changes)
- Filter by archive age (WA Age)
- Filter by content languages (WA Languages)
- Search keywords in snapshot content
- Check for CJK characters, redirects (301/302), access errors (403)
In this way, Karma.Domains is the only platform that not only allows you to search by backlinks and basic SEO metrics but also deeply analyze domain content from the Wayback Machine — something Spamzilla doesn't offer.
Intuitive Interface and In-Depth Reporting
The Karma.Domains dashboard is intuitive and built with real-world SEO workflows in mind.
For instance, the Site Technologies section shows:
- which technologies were used on the site
- what CMS and plugins were installed
The content analysis section of each unique snapshot includes:
- page titles
- meta tags
- keyword cloud
- list of backlinks (external and internal)
The ID Footprint section reveals IDs of analytics systems, social media widgets, and other integrations, helping to identify the original site owner.
Simple and Transparent Pricing
Unlike Spamzilla’s subscription model ($37/month), Karma.Domains offers two convenient options:
- Credit packages with no expiration date
- Unlimited access for 30 days at $27.99 USD, including full access to reports and up to 400 user tasks. Credits expire after 30 days.
This makes it ideal for both regular users and those working with domains occasionally.
FAQ
Does Karma.Domains include all the same metrics as Spamzilla.io?
Yes — and more. Karma.Domains supports metrics from SEMrush and Majestic, just like Spamzilla, but also adds unique filters based on Wayback Machine content, Karma Score (a transparent spam indicator), and even snapshot language and redirect detection.
Can I see domain history and content changes like in Spamzilla?
Karma.Domains goes further. Instead of just showing a list of archive dates, it groups similar snapshots and highlights real content changes, toxic topics, redirects, and language switches — making it easier to evaluate the domain’s past at a glance.
Does Karma.Domains support GoDaddy and DropCatch auctions?
Yes. Karma.Domains covers GoDaddy, DropCatch, NameJet, Dynadot, Sedo, Namesilo, and more — with daily updates for over 400,000 domains. It also includes hundreds of national TLDs like .de, .es, .fr, and others.
Can I find domains available for immediate registration?
Absolutely. There’s a dedicated section of expired domains that are already dropped and available to register without any bidding. These are curated and pre-checked for spam signals, backlinks, and archive history.
Is there a free trial or free version?
While there’s no full free plan, Karma.Domains allows limited access to domain previews and filtered search results without a subscription. You can also purchase small credit packs or a 30-day unlimited plan starting at $27.99.
Can I filter domains by backlink anchor text or keyword in content?
Yes. You can search by anchor text (via SEMrush), keywords found in snapshots (via Wayback Machine), organic keywords, and even by the presence of CJK characters or access errors. This allows highly targeted filtering by niche and region.
I use Spamzilla for PBNs — is Karma.Domains a better fit?
If your PBN strategy relies on historical trust and clean domain backgrounds, Karma.Domains offers more transparency and control. The snapshot-level content analysis and red flag alerts make it especially useful for filtering out SEO traps.
Conclusion
If you’re looking for a full-featured Spamzilla alternative with deep content analysis, transparent pricing, and a modern interface — Karma.Domains is the tool for you.
The platform is actively evolving, adding new filters, domain sources, and automation for quality control.
