The monthly traffic feature, which is at times also identified as bandwidth or information transfer, indicates the overall volume of information that is uploaded to your shared hosting account and downloaded from it each month. Your site traffic is produced primarily by web site visits - every time somebody comes across your website, the pages they view are downloaded from your hosting server to his / her machine or mobile device and they are shown by the browser. What counts for the traffic generated is the size of these webpages, so the more site visitors you get for a given period of time, the more web site traffic will be generated. Along with the site visits, file uploads will also be counted towards the entire monthly transfer i.e. if you upload website content or some other files through a file manager or an FTP software, they will also generate some website traffic. The counter resets on the first day of each month and it is not related to the date you have subscribed as well as the date you've renewed the web hosting plan.
