Deep Engagement

Deep engagement is a level of involvement beyond a shallow visit: the user spends meaningful time, sees several parts, or takes a significant action.

Deep engagement is not one metric but a qualitative threshold you define to separate came-and-went from truly engaged. Its criterion can be composite — time above a limit, scroll depth, several pages, or a key event firing — and that discretion is both its strength and its danger: too loose a threshold makes everyone look deep and the concept worthless, too strict and only a minority qualify. The biggest trap is trusting time alone; an open, abandoned tab also logs plenty of time with no attention at all, so time must be paired with an active signal (scroll, click). See deep engagement as the operational definition behind an engaged session and the engagement score, not a universal number.
