Differences between giosg analytics and other analytics services

Shortly, the methods of calculation we use in our analytics differ from other services, such as Google analytics. 

The differences are mainly caused by the way we define the length of the session and by the security settings of the visitors' browsers. Differences can also be a result of delimitations made in other analytics services, or visitors' browser settings or extensions that prevent giosg script (or other services) from loading on the page.
