For another thing, the Internet has somewhere in the neighborhood of two decades worth of traffic bot programs littering the digital ground. Some have gone through upwards of a dozen name changes and rebrands, moving from one site to another. They disappear, leaving existing users in the lurch, never to receive support or updates when the program stops working. Then identical software comes out under a new name, charging anywhere from $5 to $250, scamming people out of their cash with the same back-end software.
Web traffic is measured to see the popularity of websites and individual pages or sections within a site. This can be done by viewing the traffic statistics found in the web server log file, an automatically generated list of all the pages served. A hit is generated when any file is served. The page itself is considered a file, but images are also files, thus a page with 5 images could generate 6 hits (the 5 images and the page itself). A page view is generated when a visitor requests any page within the website – a visitor will always generate at least one page view (the main page) but could generate many more. Tracking applications external to the website can record traffic by inserting a small piece of HTML code in every page of the website.
