Final answer:
The tracking code sends an event hit every time a user performs an action with event tracking implemented.
Step-by-step explanation:
The tracking code sends an event hit every time a user performs an action with event tracking implemented. Event tracking allows you to measure interactions that users have with your website or app which are not tracked as pageviews. These interactions can include things like clicking on a button, watching a video, or completing a form.
For example, if you have event tracking set up for button clicks on your website, every time a user clicks on a button, the tracking code sends an event hit to your analytics platform. This hit contains information such as the category, action, label, and value associated with the button click event.
