# NameBio

NameBio is a searchable database of historical domain name sales. Buyers, sellers, and brokers use it to find comparable sales of similar names when they set or check a price.

## Why it matters

NameBio says its database holds more than three billion dollars in sales. It shows reported sales from auctions and marketplaces, with prices and dates. It is the main public tool for comparable sales. Its data has limits: private deals under NDA are missing, and old sales may not match today's market. Use sales of names that are close in length, type, and extension, and from recent years. Common mistake: treating the highest sale in a category as the expected price. Look at the median and at how many similar names failed to sell.
