well I have no proven data or information since it is only a domain name with no site content or meta tags. But when you google xbox updates you get 9,500,000 results, xbox you get 217,000,000. Also with proper meta tags and advertising with
www.xboxupdates.com you have a higher rate of success then some of the other xbox sites on the net that are trying to have a more catchy phrase or name but in the end is hard to remember.
Also xboxupdates has what the site is about in the name. The perfect name for a xbox site providing news and updates in the xbox universe.
