Bandwidth: How many bits are transferred between the server and its visitors. The more (and bigger) graphics and downloadable files you offer on your website, the more bandwidth your site will take, increasing the time visitors must spend on your website, and the amount of resources your host must spend on you. Taking up too much bandwidth may drive visitors away or force your host to charge you more to support your website.
