The monthly site traffic characteristic is generally known as data transfer or bandwidth as well, but all of the abovementioned terms refer to the same thing - the amount of info can be transferred to and from your hosting account. The traffic can be generated in two ways, the more obvious one being site visits. When someone goes to your website, their browser requests and downloads the pages from the website hosting server and then shows them on their end. The more site visitors you have, the more outgoing traffic is produced from your web hosting account. Since this characteristic includes the entire website traffic, not just the site visits, you shouldn't forget that inward traffic is measured too. Which means that site content and various other files that you upload to the account through a file manager or an FTP software are counted towards the account quota. Your transfer is typically tracked per month and the counter resets on the first day of every month whatever your actual date of signup.
