Screen visibility time refers to the amount of time a screen, such as a computer monitor or mobile device, is actively being viewed by a user. This includes the time spent actively engaging with the screen, as well as any passive viewing time. It is a measure of how long a user’s attention is focused on the screen, and is often used in marketing and advertising to determine the effectiveness of a particular ad or content. In today’s digital age, screen visibility time has become increasingly important as it directly impacts user engagement and brand awareness.
