The monthly traffic feature, which is sometimes also called bandwidth or data transfer, identifies the full amount of data which is uploaded to your website hosting account and downloaded from it each month. Your site traffic is generated predominantly by website visits - whenever somebody loads your web site, the web pages they see are downloaded from the website hosting server to his or her computer or mobile device and they are displayed by the internet browser. What counts towards the website traffic generated is the size of these web pages, therefore the more site visitors you have for some period of time, the more site traffic will be generated. Along with the web site visits, file uploads are also counted towards the entire monthly transfer i.e. any time you upload web site content as well as other files using a file manager or an FTP application, they'll also generate some traffic. The counter resets on the first day of each and every month and it is not related to the date you have signed up as well as the date you have renewed the hosting plan.
