The idea behind a web tracker is very simple and has been around for many years. Essentially you place a small piece of code on your website, when someone visits your website, that small piece of code is executed and the visitor's public details (ip address, browser, operating system, referrer, page title and url etc) are analysed and stored for reporting to you later.
