The monthly traffic feature, that is sometimes also referred to as bandwidth or data transfer, indicates the full volume of info that can be uploaded to your shared hosting account and downloaded from it every month. The traffic is produced mostly by web site visits - when somebody comes across your web site, the pages they view are downloaded from your hosting server to his / her machine or mobile device and they're shown by the internet browser. What counts for the site traffic generated is the size of these pages, hence the more visitors you have for some period of time, the more web site traffic will be produced. In addition to the website visits, file uploads are also counted towards the entire monthly transfer which means that when you upload web site content or some other files by using a file manager or an FTP software, they'll also generate some traffic. The counter resets on day one of each and every month and it's not related to the date you have subscribed as well as the date you have renewed your website hosting package.
