If you choose the pricing option „Run“, 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.

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.
