The correct event parameter is: “Name of a video watched on your site.”

Quick Scoop: What’s Going On Here?

When a user watches a video, that action is the event itself (for example, an event like video_play).

To understand that event better, you attach event parameters that add extra detail about what exactly happened.

In this common analytics exam-style question, you’re usually given options like:

  • How many users viewed a video on your site
  • How many users opened the page containing a video
  • The devices users are on when watching a video
  • Name of a video watched on your site

Among these, the only true event parameter is:

Name of a video watched on your site ✅

Why “Name of a video watched” Is a Parameter

Event parameters are pieces of metadata tied to a single occurrence of an event.

For a video-watch event, good parameters are things like:

  • Video title (name of the video)
  • Video URL
  • Video progress or completion percentage

These describe that specific watch event and help you answer questions like:

  • Which exact videos are most watched?
  • Which titles drive the most engagement?

That’s exactly what “name of a video watched on your site” does: it identifies which video was watched for each event.

Why the Other Options Are Not Event Parameters

Those other choices are tempting, but they are actually metrics or dimensions , not single-event parameters:

  • How many users viewed a video on your site
    • This is an aggregated metric (a count over many events), not a single-event detail.
  • How many users opened the page containing a video on your site
    • Again, a metric summarizing behavior, not a parameter attached to one watch event.
  • The devices users are on when watching a video on your site
    • Device type is normally a user/device dimension (like “mobile,” “desktop”), not a custom event parameter for the video-watch event itself.

Only “Name of a video watched on your site” fits the definition of an event parameter tied directly to that specific event occurrence.

TL;DR:
For the question “when a user watches a video, this triggers an event on your website. which of these is an event parameter?” — the correct answer is:

Name of a video watched on your site. ✅
