A page tag is a small JavaScript code that can be placed on each page of your website in order to record visitor behavior. It is used by Google Analytics and other popular web analytics programs. Page tagging is considered to be the most effective and reliable method to provide accurate and detailed data on your website visitors. Log file analysis used to be the only option to record and analyze site user data, but page tagging provides much richer data.
Every time a page is requested, it automatically runs the JavaScript in the web browser and sends information to a remote server. The captured data is then processed to display website activity. It provides easy-to-read reports and charts within the client’s analytics interface. Many times page tagging also manages the process of allotting cookies on the user’s computer to supply more reliable information.
During page tagging, the JavaScript is run automatically every time the page is loaded. Adding additional information to the JavaScript is very easy. The added information can then be collected by the remote server. With log file analysis, information can be recorded only by modifying the URL.
Moreover, page tagging can report events that do not involve a request to the web server, like communications within Flash movies. Therefore page tagging is available to companies that don’t run their own web server and is a great way to gather data to use in web analytics.
