The monthly traffic characteristic, which is sometimes also referred to as bandwidth or data transfer, refers to the overall amount of info which is uploaded to your cloud hosting account and downloaded from it each month. The website traffic is produced generally by web site visits - whenever someone loads your site, the web pages they see are downloaded from your website hosting server to their computer or mobile device and they're shown by the browser. What counts towards the site traffic produced is the size of these pages, consequently the more site visitors you have for a given period of time, the more website traffic will be produced. Along with the website visits, file uploads will also be counted towards the total monthly transfer i.e. if you upload web site content or any other files through a file manager or an FTP program, they'll also generate some site traffic. The counter resets on day one of every month and it is not related to the date you've registered and the date you have renewed the hosting package.
