How domain valuations work
Extension (.com vs others)
.com is the default for business. It commands a 3–10× premium over .net or .org for equivalent names. .io and .ai carry premiums in tech. Most other extensions trade at a significant discount.
Length and pronounceability
Shorter is almost always more valuable. One-word .coms under 6 characters are rare and expensive. Names that are easy to say, spell, and remember sell faster and for more.
Keyword commercial value
Domains containing high-CPC search terms (insurance, loans, attorney, mortgage) carry a premium because they attract type-in traffic and rank well. Check Google Keyword Planner for monthly search volume.
Comparable sales (comps)
The most reliable signal. Search NameBio for similar domains that have sold. A domain is worth what a buyer will pay - comps tell you what buyers have actually paid for similar names.
Domain age and history
Older domains with clean histories are worth more. Check the Wayback Machine and a WHOIS history tool. Domains previously used for spam or adult content are nearly impossible to sell at a premium.
Brandability
Made-up words that sound like real brands (Stripe, Slack, Zoom) sell well to startups. The name should be easy to say on a phone call, fit on a business card, and work as a social handle.
Market context
These verified sales from NameBio and public records show the range of what premium domains fetch. Most domains sell for far less - the median aftermarket .com sale is in the $1,000–$5,000 range.

Auction vs marketplace vs brokerage
Auction value
What you'd likely get in a competitive auction with a time limit. Typically the lowest of the three - buyers know they can win at a discount. Good for domains with clear demand and multiple potential bidders.
Marketplace value
The "buy now" price on platforms like Afternic, Sedo, or Dan.com. This is the middle estimate - what a motivated buyer would pay without the pressure of an auction. Most domains sell in this range.
Brokerage value
What a broker might achieve through direct outreach to end-users. The highest estimate - brokers find buyers who need the domain for their business and can justify paying a premium. Takes longer but yields the best price.
