•Pageviews: The number of times a web browser requests a text or html file, which shows a truer reflection of the actual documents requested from your site.
•Sessions: The number of unique hosts accessing the server during a given period of time – unique visitors.
•Kbytes Sent: The amount of data sent during the summary period as reported by the server.
