Question: When a user watches a video, this triggers an event on your website. Which of these is an event parameter?
- Name of a video watched on your site
- The devices users are on when watching a video on your site
- How many users opened the page containing a video on your site
- How many users viewed a video on your site
Explanation
An event parameter provides additional information about a specific event in Google Analytics 4. For a video interaction, the video name describes the content associated with the event. Parameters add context to events so they can be used in reporting when configured as custom dimensions or metrics. This differs from metrics, which count activity, and dimensions that describe broader user or device attributes.
Why the other options are incorrect
Devices describes the device category or technology context, not a parameter of the video event.
Users viewed a video is a metric that counts users, not descriptive event metadata.
Users opened the page is a metric tied to page activity, not an event parameter.
