I made a significant amount of money buying and selling domains over the years. Aged domains with strong backlink profiles, dropped domains from expired businesses, auction finds from GoDaddy and Dynadot — I worked across all of it.
But the research was brutal.
To evaluate a single domain properly, I had to open four or five browser tabs: Ahrefs for DR, Moz for DA and spam score, Majestic for Trust Flow, and then the Wayback Machine to manually dig through the site's content history — because a domain's backlink profile means nothing if it spent three years hosting casino spam or pharmaceutical doorways.
I would do this for dozens of domains at a time. It was slow, repetitive, and easy to miss things.
That is the problem Karma.Domains solves — and it solves it better than anything else I have used.
What Is Karma.Domains?
Karma.Domains is an expired domain aggregator and analytics platform. It does not sell domains — it pulls inventory from 40+ auction sources (GoDaddy, Dynadot, NameJet, Sedo, Namecheap, NameSilo, NicSell, DropCatch, Porkbun, Sav.com, and more) and gives you a unified interface to search, filter, and analyze them.
The database currently holds 8 million+ domains. Over 400,000 new domains are added every day. Auction data updates hourly.
What separates Karma.Domains from a simple aggregator is the analysis layer. Every domain gets evaluated against its full Wayback Machine history for content quality, spam signals, language changes, redirect patterns, and toxic content. That analysis produces the platform's proprietary Karma Score — the metric that changes how you evaluate domains.
The Karma Score: Why It Matters
A domain with Ahrefs DR 50 and 2,000 referring domains sounds excellent. But if that domain spent 2018–2023 as a pharmaceutical spam site before someone cleaned it up, those backlinks may be flagged or discounted by Google — and they will carry that history into your project.
The Karma Score is Karma.Domains' answer to this problem.
It is a proprietary metric based on Wayback Machine snapshots, scoring how clean or spammy a domain's entire content history has been. The platform flags:
- Toxic content — pharma spam, casino, adult content, piracy, doorway pages
- Sharp content changes — sudden shifts in topic, language, or theme (often a sign of spammer takeovers)
- Server responses — 3xx redirect chains, 4xx/5xx error periods
- Ownership changes — registrar placeholder periods, hosting provider switches
A domain with a Karma Score of 100 has a clean, consistent history. A domain scoring 20 or 30 has red flags worth investigating before you spend money on it.
Before Karma.Domains, catching this required spending 20–30 minutes manually reviewing Wayback Machine snapshots for each domain. The platform does it automatically, at scale, across millions of domains.
Database and Auction Sources
The platform aggregates inventory from 40+ sources across multiple listing types:
Auction platforms: GoDaddy, Dynadot, NameJet/Snapnames, Sedo, GNAME, Namecheap, NameSilo, NicSell, DropCatch, Park.io, Porkbun, Sav.com, Aftermarket.pl, Subreg, WebExpire, DomainLore, WHC.ca
Listing types covered: Auctions, Buy Now, Backorder, Pre-Release, Dropped, Closeout
TLD coverage: .com, .net, .org, .info, .biz, country-code TLDs (.co.uk, .ca, .at, .be, .cl, .co.nz, and more)
Bid counts and prices update automatically, so you are not working from stale data when evaluating auction domains near their end time.
The platform also has an auction calendar reminder — you can set a notification for one hour before a domain's bidding ends, with links to both the lot and the full Karma.Domains report.
90+ Search Filters
This is where the platform earns its place in a serious domain research workflow. You can filter across:
SEO metrics:
- Ahrefs: DR, UR, Ahrefs Rank
- Moz: DA, Spam Score, Backlinks, Referring Domains, Backlink URL, Anchor text
- Majestic: Trust Flow, Citation Flow, Backlinks, Referring Domains, Topics, Language
- Semrush: Authority Score, Backlinks, Referring Domains, Referring IPs, EDU/GOV backlinks, traffic data
- SimilarWeb: Visits, traffic by channel (direct, search, referral, social, paid)
Content and history filters:
- Wayback Machine: content age, first/last snapshot, content changes, language, keywords in content, server code share, CJK hieroglyphs, 3xx redirects, 4xx/5xx errors
- Google SERP: indexed status, Google mentions, keyword in title/description
- Keywords Everywhere: Estimated Traffic Value, total keywords
Domain structure filters:
- TLD type (gTLD, ccTLD)
- Word count, character length, hyphen count, digit count
- Karma Score (min/max)
- Auction source, price, bid count, end time, category
Saved filters: You can save any filter combination with a name and reuse it in one click — critical if you have a repeatable sourcing criteria.
For most domain buyers, manually configuring this level of filtering across Ahrefs, Moz, Majestic, Semrush, and Wayback Machine separately would take hours. Karma.Domains runs it in seconds.
AI Features
Karma.Domains has been adding AI functionality steadily. The current feature set includes:
AI natural language search — describe what you want in plain language ("English-language tech blog domain with DR 30+, clean history, no gambling content") and the AI translates it into a filter query automatically. Useful if you find the filter panel overwhelming on first use.
AI domain history summary — each domain report includes an automatically generated summary of the complete history: what sites were hosted, what content was published, when and how frequently the profile changed.
AI domain categorization — domains are automatically tagged by topic (news, technology, education, health, etc.), so you can filter by category without manually reviewing each domain's Wayback snapshots.
MCP server — Pro plan users can connect Claude, Cursor, and ChatGPT to Karma.Domains via the Model Context Protocol. You can search, shortlist, and analyze domains directly from an AI assistant interface. OAuth browser sign-in was added in September 2026 for Claude.ai and ChatGPT, making the setup significantly simpler.
Wayback Machine Analysis
The Wayback Machine integration is the most differentiated part of the platform. Every domain report includes:
- Timeline view — content snapshots across the domain's full history in a structured interface, not the raw Wayback Machine archive browser
- Content change analysis — detailed breakdown of how content, keywords, language, and meta tags changed between periods
- Technologies and footprints — which CMS, hosting providers, and registrars the domain used, which helps identify patterns from previous owners
- Toxic content detection — automated flagging of pharma, casino, adult, piracy, and hacked redirect content across all available snapshots
- Redirect and error analysis — 3xx redirect chains and 4xx/5xx error periods mapped to specific time ranges
This is the most time-consuming part of manual domain research. Karma.Domains automates all of it and presents it in a readable format within the domain report.
Automation and API
For researchers running bulk workflows, the platform has:
- RSS feed — subscribe to any saved filter; new matching domains arrive as a feed
- Daily email digest — receive a daily summary of new matches for saved filters
- Public API (Pro plan) — REST API with OpenAPI schema, up to 60 requests/minute, for integrating Karma.Domains into scripts, CRMs, or custom tools
- MCP server (Pro plan) — connect AI tools directly, same API key as REST
- Custom domain list upload — paste or upload your own domain list and run it through the full Karma.Domains analysis pipeline
- Report notes and tags — add private notes (up to 200 characters) and tags to any domain for personal organization

Who Should Use Karma.Domains?
The platform makes sense for:
- SEO professionals buying expired domains for 301 redirects, PBNs, or niche site projects — the Karma Score and toxic content detection are directly relevant
- Domain investors who buy and flip domains — the aggregated auction view across 40+ platforms removes the need to check each platform manually
- Agencies managing multiple client SEO strategies with expired domain acquisition as a component
- Developers and researchers who want API or MCP access to automate domain sourcing
- Anyone transitioning from ExpiredDomains.net or Spamzilla who wants deeper Wayback Machine analysis and a cleaner interface
It is less relevant for someone registering a new domain for a fresh project — that is not what the platform is built for.
FAQs
Is Karma.Domains free to use?
You can browse the domain list and see basic metrics without signing up. After signing up (no credit card required), you receive 5 free credits to unlock full domain reports. Paid plans start from $14.99 for a credits pack or $27.99/month for unlimited access.
Does Karma.Domains sell domains?
No. It is an aggregator and analytics platform. When you find a domain you want, the report shows you where to buy it — the relevant auction platform (GoDaddy, Dynadot, etc.) or direct registration with a registrar for expired domains.
What is the Karma Score?
The Karma Score is Karma.Domains' proprietary metric derived from Wayback Machine snapshot analysis. It scores how clean or spammy a domain's content history has been — flagging toxic content, sharp topic changes, redirect abuse, and server errors. A higher score means a cleaner history.
How is Karma.Domains different from ExpiredDomains.net?
ExpiredDomains.net is primarily a listing aggregator with basic SEO metrics. Karma.Domains adds deep Wayback Machine analysis, the Karma Score for spam detection, AI-powered search, categorization, and structured domain history reports. For a full comparison, see the best alternatives to ExpiredDomains.net.
How is Karma.Domains different from Spamzilla?
Both platforms analyze expired domain history, but Karma.Domains aggregates more auction sources (40+), offers more SEO metric integrations (Ahrefs, Moz, Majestic, Semrush, SimilarWeb), and adds AI-powered search and MCP integration. The Karma Score is a similar concept to Spamzilla's spam analysis but is built on its own methodology.
Can I use Karma.Domains with AI tools like Claude?
Yes — on the Pro plan, Karma.Domains offers an MCP server that connects Claude, Claude.ai, Cursor, and ChatGPT directly to the platform. You can search for domains, shortlist candidates, and review reports from within an AI assistant. OAuth sign-in (no API key paste) was added for Claude.ai and ChatGPT in September 2026.
Do credits expire?
No. Credits purchased on Karma.Domains never expire and remain in your account until you use them.
Is Karma.Domains Worth It in 2026?
When I was buying and selling domains manually, the Wayback Machine research alone was the single biggest time sink in my workflow. Every domain that looked good on paper required 20–30 minutes of history verification before I could trust it.
Karma.Domains automates that step — and does it at a quality level I could not consistently match manually at speed.
The Karma Score is not a perfect filter. Some domains with moderate scores are perfectly usable, and a high score does not guarantee ranking performance. But it eliminates the worst purchases and dramatically reduces the time spent on domains that would have failed manual verification anyway.
At $27.99/month for full access — or pay-per-report credits for occasional use — it is genuinely affordable for what it replaces. The 5 free credits let you verify that the output matches your expectations before spending anything.
If you are actively researching expired domains for SEO, domain investing, or affiliate site building, Karma.Domains belongs in your workflow. It is the best tool I have found for this specific job.
