An invented domain name with vague connotations of "you", which could be used by almost any business or brand, but especially those linked to some kind of personal identity.
The word "yuuo" contains only four characters and only two syllables. Two-syllable names are very rare and extremely prestigious. Leading companies using two syllable names include WeChat, Twitter and Ikea.
This domain was first registered in January 2005. Older domains have an advantage when ranking in search engines.
