Question: You have an event on your website that triggers when users watch a video. Which of these is an example of an event parameter?
- How many users opened the page containing a video on your site
- The devices users are on when watching a video on your site
- The name of a video users watched on your site
- How many users viewed a video on your site
Explanation
An event parameter adds contextual detail to a collected event. For video engagement measurement, parameters such as video_title describe the specific content associated with the interaction. This differs from metrics, which count activity, and dimensions, which classify users or sessions. In Google Analytics, parameters can populate reportable dimensions when they are collected and supported.
Why the other options are incorrect
Page opens is incorrect because it describes a count of users, not contextual event detail.
Video views is incorrect because it describes measurement volume, not a parameter value.
Viewer devices is incorrect because device category is collected as a user or session attribute, not a video event parameter.
