The monthly traffic feature, that is at times also identified as bandwidth or data transfer, identifies the full volume of data that can be uploaded to your hosting account and downloaded from it every month. Your traffic is generated mostly by site visits - each time someone finds your web site, the webpages they view are downloaded from your web hosting server to his / her computer system or smartphone and they are shown by the internet browser. What counts for the site traffic produced is the size of these pages, as a result the more website visitors you get for a period of time, the more website traffic will be generated. Along with the website visits, file uploads are also counted towards the entire monthly transfer this means that every time you upload website content or some other files using a file manager or an FTP application, they will also produce some traffic. The counter resets on the very first day of each month and it's not related to the date you have subscribed and the date you have renewed your web hosting plan.
