What do "counters" measure in Studio?

Counters in Studio measure the number of times a specific action occurs within a creative. This is crucial for tracking user engagement, such as clicks on a button, form submissions, or specific interactions with dynamic elements. For example, a counter could track how many times a user expands an accordion or clicks a "learn more" link. While elapsed time interacting with a creative element (option B) and length of time a video creative is played (option D) are also important metrics, they are typically measured by timers or video tracking events, not counters. The number of users that did not interact (option A) is a derived metric, not a direct counter measurement.
