To track your presentation’s stats using Google Analytics, click on the gear next to your presentation title and select Share, then check the Google Analytics box and insert your tracking ID. It should be a 12 character sequence that looks something like this: UA-000000-01.
To access the in-app analytics select the Stats tab from the panel. The in-app analytics feature will only show basic stats from all your presentations: cumulative and daily number of views.
Add the Google Analytics Code before you share your presentation’s link.
