Comparable sale
A previously-sold domain similar in length, TLD, and theme used as a price reference. Cited via NameBio, DNJournal, or first-party marketplace data.
How to read comps
Good comps share at least two of: TLD, length, semantic category, and recent sale date (within 24 months). A 4-letter .com sale 8 years ago is interesting context, not a current floor.
Where to look
NameBio is the public industry archive. DNJournal publishes a weekly verified-sales list. Deepnom’s own intel module ingests both.
