Nice, invented business domain name which could be based on the Italian word "zanzero" (as in 'drinking companion').
Zanzeo has only six characters and only two syllables. Two-syllable names are extremely rare and highly valuable. Successful brands using two syllable names include Ikea, Hilton and Buffer.
Zanzeo.com is a .com domain. Dot com is the most valued domain extension. Once secured, a .com all but guarantees no-one else can outrank you for your own name in the long run.
This domain was first registered in April 2010. Older domains have an advantage when ranking in search engines.
