In GA4, engagement rate is engaged sessions divided by all sessions. Under the documented definition, an engaged session meets a duration criterion, contains a qualifying key event or includes multiple page or screen views; bounce rate covers the non-engaged sessions.[1] This measure concerns web or app sessions, not social interactions per impression or person reached.
Use the rate to investigate whether visitors move beyond a fleeting contact, but not as a substitute for sales outcomes. A comparison shopper may read extensively without buying, while a regular customer may complete an order quickly. If the rate changes unexpectedly, inspect event settings and traffic mix first. A technical definition change can move the measure without a corresponding change in purchase intent.
