Having a site is a bit more complex than having a domain name and uploading files for it on a server. The web hosting service also features things like domain records, databases, email addresses, stats, FTP access, and so on. Though they probably are not the first thing that comes to mind when you bring up the word “website”, they are an integral part of any site and none of them can be neglected. If you wish to start and keep a profitable online presence, you'll need an easy way to take care of these things, particularly if you aren't very knowledgeable. Apart from the convenience, it is also important to have 100 % control over your domain addresses and the web hosting service associated with them.
