When a user watches a video, this triggers an event on your website. Which of these is an event parameter?

Analysis of Correct Answer(s)

In Google Analytics 4, an event is any user interaction, and an event parameter provides additional context about that specific interaction.

• Name of a video watched on your site: This is the correct answer because it's a specific piece of data that describes the event. When a "video_play" event is triggered, you can send a custom parameter like video_title with the actual name of the video as its value. This allows you to analyze which specific videos are most popular.

Analysis of Incorrect Options

The other options represent metrics (aggregated counts) or dimensions (attributes of users/sessions), not event parameters.

• How many users viewed a video on your site: This is a metric. It is a total count that you would find in a report, calculated by aggregating individual events. It is not a piece of information sent with a single event.
• The devices users are on when watching a video on your site: This is a dimension (e.g., 'Device Category'). Google Analytics collects this data automatically for segmenting reports. While it provides context, it's not a parameter you would send to describe the content of the video event itself.
• How many users opened the page containing a video on your site: This is another metric. It is a count of users performing a different action (page_view), not a parameter describing the video watch event.
