The monthly traffic feature, which is at times also identified as bandwidth or data transfer, indicates the full volume of info which can be uploaded to your website hosting account and downloaded from it every month. Your site traffic is produced mostly by web site visits - every time somebody visits your site, the pages they view are downloaded from the website hosting server to their computer or smartphone and they are shown by the web browser. What counts towards the website traffic generated is the overall size of these web pages, consequently the more website visitors you have for a given period of time, the more traffic will be generated. In addition to the website visits, file uploads are also counted towards the total monthly transfer i.e. every time you upload web site content as well as other files using a file manager or an FTP application, they'll also generate some site traffic. The counter resets on the very first day of each and every month and it's not related to the date you've signed up or the date you've renewed your hosting package.
