When is an event hit sent to Google Analytics?

An event hit is sent to Google Analytics specifically when a user performs an action that is tracked using event tracking. Event tracking is a feature that allows you to log user interactions with content that does not involve a webpage loading or require a pageview. For instance, this includes actions such as clicking on a video play button, downloading a file, or engaging with a specific feature on a site like a button or a widget.

The purpose of event tracking is to gather detailed interaction data about elements that are not necessarily tied to traditional page views. This is crucial for understanding user engagement and behavior beyond mere visits to pages.

While there may be instances in which a booking or reservation counts as an event, it does not inherently send an event hit by virtue of every action performed. Similarly, adding events to a calendar does not automatically involve Google Analytics event tracking unless specifically implemented. Pageview tracking, on the other hand, involves entirely different data sending processes and is unrelated to the concept of event hits. Therefore, defining the trigger for event hits helps clarify how interactions are recorded in Google Analytics.
