Bandwidth - This is the amount of traffic you receive at your site or the amount of files being accessed on your site. A good average is 1 meg for 5 visitors but it really depends on images and content. If you have a lot of large image files you may expect more bandwidth usage per visit. On average a site with a moderate amount of pictures that receives 500 visitors a month will use about 100 megs of bandwidth. For the most part the visitors will come because they did a search for your company name, service, or product, so it is profitable to use a lot of bandwidth.
