What is an example of an event parameter when a user watches a video on a website?

An event parameter provides specific details about an event that occurs on a website. In the context of a user watching a video, the name of the video watched is an appropriate example of an event parameter. It identifies which specific video was interacted with, allowing for more granular analysis of user behavior and content performance. By tracking the names of videos watched, website owners can gain insights into viewer preferences and adjust their content strategy accordingly.

While the other choices provide relevant information about the video viewing experience, they do not serve as direct event parameters in the same way. For instance, the date and time of the video watch could be part of the event's metadata but does not specifically describe the event itself. Similarly, the length of the video is a characteristic of the video, not of the action taken by the user. The number of times the video was viewed might indicate engagement levels but is a broader metric rather than a specific event parameter associated with individual video interactions. Thus, the name of the video stands out as the most accurate representation of an event parameter in this context.
