Short answer

Average engagement time is a Google Analytics 4 metric showing the average time a website or app was in the foreground or in focus on the user's device, calculated per user or per session. Unlike older time-on-page measures, it excludes time when the page sat in a background tab, giving a more realistic view of attention.
