In order to choose the right hosting plan you’ll want to consider a few things:
Design
How was your Web site designed? For example, if you designed an ASP or ASP.NET Web site, you'll need to find a Windows hosting plan. If you have a Web site that uses CGI or PHP you'll need to get a Linux hosting plan.
Traffic
How much traffic or how many visitors do you expect monthly? The more visitors or traffic you expect on your site, the higher the bandwidth you will need.
Size
How large is your site? If you're planning on having a large site with a lot of multimedia content you'll probably need additional disk space.
