Starting from the "Run“ plan, you are able to use Google-Analytics. You can then see the number of page impressions and several other statistical values. To do this you have to click on "Settings", scroll down and enter your Tracking-ID.
Important: Google has introduced a new standard with G4. These new functions for tracking "events" are not necessary for the rudimentary tracking method in Pageflow. Therefore, when creating a new property, please make sure to create a Universal Analytics-Property via "Advanced Settings". The tracking ID of a Universal Property starts with the letters "UA-XXXXXX".

To track your stories, please click on "Behaviour" and "Overview". Pageflows can be identified there by the URL. Every session - wether 1 or 50 page visits within one Pageflow - counts as only 1 user.
