Buying expired domains is a market with very different prices for the same goods depending on where you shop. The exact same DR 35 domain can cost $80 at one marketplace and $1,200 at another — both for technically the same asset. Understanding which marketplace serves which use case is the difference between a sustainable expired domain pipeline and a budget destroyed by bidding wars. This is the breakdown of where to actually buy, what each source is good for, and how to combine them.
The 3 categories of expired domain marketplaces
Every expired domain source falls into one of three categories:
- Auction-based marketplaces. Domains that recently expired go to auction. Multiple buyers compete via bidding. Examples: GoDaddy Auctions, NameJet, SnapNames, DropCatch.
- Aggregator databases. Sites that crawl the auction marketplaces (and sometimes other sources) and present pre-filtered prospects with metrics. Examples: ExpiredDomains.net, SpamZilla, DomCop, FreshDrop.
- Direct brokers and private sales. Domains acquired by individuals or companies and sold privately or through brokerage networks. Examples: Sedo, DomainState, private marketplaces, individual sellers on SEO Twitter/forums.
Each category serves different buyer profiles. Auctions are best for volume hunters who can spend time. Aggregators are best for selective buyers willing to pay a premium for curation. Brokers are best for buyers seeking specific niches who'll pay for sourcing.
Auction-based marketplaces
GoDaddy Auctions
The largest expired domain marketplace by volume. Hundreds of new auctions daily, mostly domains that expired at GoDaddy or one of its many subsidiary registrars. Price range: $11 minimum bid to $50,000+ for desirable domains. The bulk of usable inventory sits at $50-500.
Best for: Volume buyers comfortable with high noise-to-signal ratio. The platform doesn't filter by SEO metrics, so you need external tools to find the worthwhile listings.
Account requirement: Free to register, no fee to bid. Membership program ($4.99/mo) offers some benefits but isn't required.
Watch for: Auction sniping in the final minutes is common. Set max bids in advance rather than trying to win in real time, or use a sniping tool.
NameJet
Second-largest expired auction platform. Many domains here are exclusive — they don't appear at GoDaddy because the registrar partners exclusively with NameJet for backorder service. This makes NameJet essential for completeness, not optional.
Price range: similar to GoDaddy, but the higher exclusivity means certain high-quality domains only show up here.
Best for: Buyers serious enough about expired domains to monitor multiple platforms. Skipping NameJet means missing 30-40% of the available inventory at any given time.
Quirks: Pre-bid system. You can place a backorder for $69 on a domain that hasn't expired yet — if it eventually expires and goes to auction at NameJet, you get priority access.
SnapNames
Operated by the same parent company as NameJet (Web.com). Similar inventory profile, somewhat smaller volume. SnapNames is most useful for accessing domains exclusive to specific registrars in its partnership network.
Best for: Completionists. If you're already monitoring NameJet and GoDaddy, SnapNames adds 5-15% more inventory worth checking.
DropCatch
Specializes in "catching" domains immediately after they drop from a previous registrar. Their infrastructure has hundreds of registrar accounts to maximize success rate at the exact moment of expiration. The domains they catch then go to auction.
Best for: Highly specific domain hunting where you have a target list. DropCatch is more responsive to backorders than the other platforms, but inventory tends to be higher-end (more competition, higher prices).
Park.io
Smaller and more curated. Used to be primarily for .io and tech-focused domains; now broader. Pricing tends to be higher than GoDaddy but the curation level means less time required to find good prospects.
Aggregator databases
ExpiredDomains.net
The de facto standard aggregator. Free tier covers the basics; pro tier ($69/mo) adds historical data, more granular filters, and bulk export. Aggregates from GoDaddy Auctions, NameJet, SnapNames, DropCatch, and other smaller sources.
Best for: The entry point for most expired domain operators. Sort and filter by DR, age, niche, TLD, before clicking through to the source marketplace to actually bid.
Critical filters to use:
- Only show .com (or your target TLD)
- Backlinks count: 30+ unique referring domains
- DR/PA range: tailored to your target
- Exclude domains with adult or gambling keywords in the name
SpamZilla
Paid only ($97/mo). The strongest pre-filtering on the market. Each prospect comes pre-evaluated with all the major metrics (DR, TF, CF, Spam Score, anchor analysis, Wayback summary). Saves significant vetting time.
Best for: Operators buying 2+ domains per month. The $97 subscription pays for itself if it saves you from one bad purchase.
Limitation: Still requires you to do full deep vetting before purchase — the automated filters catch most red flags but not all.
DomCop
Another paid aggregator ($49-247/mo depending on tier). Similar value proposition to SpamZilla with different metric emphasis. Some operators prefer DomCop's UI; others prefer SpamZilla's filters. Worth testing both with free trials before committing.
FreshDrop
Domain-prospecting database. Less SEO-focused than SpamZilla and DomCop. Better for domain investors looking at brandable names than for SEO operators looking at backlink profiles.
Direct brokers and private sales
Sedo
The largest marketplace for buy-now expired and aftermarket domains. Inventory is broader than auctions because it includes domains owned by investors who acquired them years ago and are reselling. Prices tend to be higher than auctions but you skip the bidding process.
Best for: Specific domain hunting where you know exactly what you want. Sedo's search is good for finding category-specific names.
DomainState / DNAcademy / Domaining communities
Forums and Discord servers where domain investors and SEO operators trade privately. Quality and pricing vary wildly. Best accessed through participation rather than transactional buying.
Direct outreach to dormant domain owners
The lowest-cost source if you have time. Use WHOIS to find owners of domains relevant to your niche that haven't been actively used in years. Make an offer. Many owners will sell for $50-200 a domain they forgot they owned and would otherwise lose at next renewal.
Best for: Operators with niche-specific needs and patience for outreach work. Lowest cost per quality domain but highest time investment.
SEO agencies selling their network
Occasionally agencies dismantle their PBNs (after Google penalties or strategic shifts) and sell off the inventory privately. These come with documented history but require trust verification.
Comparing the marketplaces: pricing, competition, quality
Approximate comparison for a typical DR 30-40 niche-aligned expired domain:
- GoDaddy Auctions: $80-300. Highest competition. Most variable inventory. Best entry point.
- NameJet: $150-500. Medium competition. Some exclusive inventory.
- SnapNames: $100-400. Lower competition. Smaller inventory.
- DropCatch: $200-800. High prices for exclusive domains it catches.
- Sedo (buy-now): $400-2,000. No bidding, immediate purchase, premium for convenience.
- Direct outreach: $50-300. Time-intensive but lowest price floor.
- Private/broker sales: $300-1,500 typically, but high variance.
The same domain quality at different sources reflects market efficiency — convenience and exclusivity command premiums, while marketplaces with high noise (GoDaddy) reward operators who can filter quickly.
A practical workflow across multiple sources
The workflow I recommend for someone buying 2-5 domains per month:
- Daily (10 min): Check SpamZilla or DomCop for new pre-filtered prospects matching your saved searches. Tag 5-10 candidates for closer review.
- 2-3x per week (30 min): Visit ExpiredDomains.net to scan auctions ending in the next 24-48 hours, filtered to your criteria.
- Weekly (60-90 min): Do full deep vetting on the 3-5 most promising candidates (the 9-metric checklist from the vetting guide). Set max bids based on the scoring framework.
- As auctions end: Place bids through the source marketplace (GoDaddy, NameJet, SnapNames). Use sniping tools if available to avoid emotional bidding.
- Monthly (variable): Send 5-10 outreach emails to dormant domain owners in your niche. Even a 10% conversion rate at $100-200 per domain produces excellent value.
How to avoid expensive bidding wars
- Set max bids in advance and don't exceed them. The single most important rule. Once you start chasing past your pre-set max, the math stops working.
- Avoid auctions with 10+ bidders already. Visibility attracts more visibility. Domains with thin bid history often go for less than equivalent quality with thick bid history.
- Bid on Sunday nights or holidays. Less competition from professional buyers means lower final prices on inventory that happens to expire then.
- Search for less-popular keyword patterns. A domain matching "best widgets review" attracts every affiliate operator. A domain in a specialized niche (e.g., "industrial valve testing") has natural moats against bidding crowds.
- Use NameJet backorders strategically. The $69 backorder fee can be cheaper than competing at auction if you're confident in the domain's value.
- Combine multiple sourcing methods rather than relying on one marketplace. Diversification reduces the leverage any single auction has over your pipeline.
Frequently asked questions
What's the cheapest way to buy expired domains?
Direct outreach to dormant domain owners — domains can often be acquired for $50-200 with patience. Second cheapest: GoDaddy Auctions for niches with low bidder competition. Most cost-effective per-quality: combining ExpiredDomains.net for prospecting + GoDaddy/NameJet for purchase.
Is it worth paying for SpamZilla or DomCop?
If you buy more than 1-2 domains per month, yes. The pre-filtering saves significant vetting time and reduces the rate of bad purchases. For occasional buyers (one every 2-3 months), the free tier of ExpiredDomains.net plus your own vetting is more cost-effective.
How do I know if a marketplace listing's metrics are current?
They may not be. Always verify the listed DR/TF/spam score by running your own check in Ahrefs/Majestic/Moz before bidding. Some listings show stale metrics, especially on aggregator sites that may not refresh data daily.
What's the difference between GoDaddy Auctions and just buying from GoDaddy directly?
Direct buying from GoDaddy gets you fresh, never-registered domains at standard registration prices ($12 first year). GoDaddy Auctions are for previously-registered domains that expired, going to the highest bidder. The two serve completely different purposes — you can't get an expired/aged domain via direct buying.
Are private/broker domains worth the premium?
Sometimes. The premium typically reflects: documented history, no public auction creating bidder competition, possible exclusivity, and broker reputation for vetting. For specific high-quality niches, the markup is justified. For generic domains, public auctions offer better value.
How quickly do auctions move on these platforms?
Most auctions run 7-10 days from listing to close. Recently-expired domains may go to auction within 24-48 hours of expiration. Set up saved searches with email alerts so you don't miss inventory matching your criteria.
Can I buy expired domains internationally (non-US registrars)?
Yes, but the platforms above are US-centric. For .co.uk, .de, .fr and other country-code domains, you may need to use regional platforms (PARK.IO has some international, otherwise look for country-specific equivalents). For .es, AuctionDomain has Spanish inventory.
