We have a web page using Google's new analytics.js Event Tracking with the following user flow:
User lands on home page
User is presented with a visible "Play" button
User clicks the Play button, a Google Event is captured:
ga('send', 'event', 'videos', 'play');
and a previously invisible "Stop" button is now made visible
User clicks the newly visible Stop button, a google Event is captured:
ga('send', 'event', 'videos', 'stop');
Our Google Analytics stats are showing that the Total count of
play event actions is greater than the Total count of
stop event actions. Almost a 2:1 ratio. That makes sense as clicking 'play' is required to present the 'stop' button, and not every user will ultimately click the stop button. Some may watch until the end of the video.
The problem we're seeing is in the count of Unique events.
The count of Unique events for the
stop event action is greater than the Unique events for the
play event action. Almost 25% higher.
How is this possible when a click of the 'play' button is required in order to see and click the 'stop' button? The videos are not longer than the standard Google Analytics 30min visit session so it's not an issue of session timeout between the
stop event interactions.
