WHAT IS GOOGLE ANALYTICS?
When a browser visits a web page, it must download the information on that page to the reader’s local computer. When that information is downloaded, the web site can include a script that will count that browser and reader as a “unique” user for that day.
Adding up all of those users, browsers and readers is called Analytics. It is a way of analyzing website traffic, who is visiting a web site, how often they are visiting, what information they are viewing and where they are from.
