Having a site is more complex than just having a domain and uploading files for it on a web server. The website hosting service includes things such as domain records, databases, e-mail addresses, stats, FTP access, etc. Although they may not be the first thing that comes to mind when you bring up the word “website”, they are a fundamental part of any site and none of them can be overlooked. If you'd like to start and maintain a profitable web presence, you will need a simple way to control all these things, particularly if you aren't very proficient. Apart from the convenience, it's also important to have full control over your domain names and the web hosting service associated with them.
