Comparable Sales Methodology: The Gold Standard of Domain Valuation

Why Comps Matter

Just as real estate appraisers use comparable property sales, domain valuators use comparable domain sales. A comp-based valuation grounds pricing in actual market behavior rather than speculation or wishful thinking. It is the methodology most respected by buyers, sellers, brokers, and arbitrators.

Finding Comparable Sales

Primary Data Sources

• NameBio: The largest database of publicly reported domain sales, with over 1 million records. Essential for any serious valuation work.
• DNJournal: Tracks weekly reported sales from major registrars and aftermarket platforms.
• GoDaddy Aftermarket: Provides historical sales data for transactions on their platform.
• Sedo: European-focused marketplace with its own sales history records.
• ShortNames.com: Specialized database for short domain sales.

What Makes a Good Comp

A strong comparable sale shares multiple characteristics with the domain being valued. The more characteristics it shares, the stronger the comp.

• Same TLD: A .com comp for a .com domain, a .io comp for a .io domain
• Similar length: A 6-letter domain comped against other 6-letter domains
• Similar keyword category: Finance terms against finance terms, tech against tech
• Recent sale date: Sales within the last 2-3 years are most relevant. The market shifts over time.
• Similar commercial intent: High-value industry keywords against similar industry keywords

Analyzing and Adjusting Comps

Raw comparable sales data needs interpretation. A domain that sold for $50,000 two years ago in a different industry is not a direct comp. Consider these adjustment factors:

Recency adjustment. The domain market has generally appreciated for premium names. A sale from 2020 may understate current market value by 10-30% for quality names. However, speculative names may have depreciated.

Industry adjustment. Insurance and finance domains command higher prices than, say, gardening domains. If your comp is from a higher-value industry, adjust downward, and vice versa.

Brandability adjustment. A domain that doubles as a strong brand name (short, memorable, easy to spell) warrants a premium over a purely descriptive keyword domain of similar length.

Traffic adjustment. If your domain has established traffic and the comp did not (or vice versa), adjust accordingly.

Presenting a Comp-Based Valuation

When using comps to justify a price, present three to five strong comparables. Include the domain name, sale price, sale date, and source. Explain why each comp is relevant. Acknowledge differences and explain your adjustments. A well-documented comp analysis is the most persuasive tool in a domain negotiation.
