description NameBio Overview
NameBio is the premier database for historical domain sales. While it is not an 'appraisal' tool in the sense of generating a single number, it is the most important resource for determining value through comparable sales. By searching for similar keywords or extensions, users can see exactly what similar domains have sold for in the past. This empirical data is far more reliable than any automated algorithm, making NameBio an indispensable tool for anyone serious about buying or selling domains at fair market prices.
