Having a site is more challenging than having a domain and uploading files for it on a web server. The web hosting service includes things like domain records, databases, e-mail addresses, stats, FTP access, and so on. Although they are probably not the first thing that comes to mind when you refer to the word “website”, they are a fundamental part of any website and none of them can be skipped. If you wish to start and sustain a profitable online presence, you will need an easy way to take care of these things, particularly if you are not very proficient. Aside from the convenience, it's also important to have total control over your domain addresses and the hosting service related to them.
