In Google Analytics 4 1 a session is engaged if it lasts longer than 10 seconds, triggers a key event or views two or more pages; bounce rate is "the percentage of sessions that were not engaged." No Google documentation names Analytics bounce rate as a ranking signal, and Google cannot see it on sites without Analytics. Dwell time and pogo-sticking (returning to the results to click another listing) are a different matter: the leaked lastLongestClicks and badClicks attributes suggest Google classifies clicks this way, but thresholds and weights are unknown. A one-page visit that answers the question is a success, so optimize for satisfied visitors, not for a lower bounce number.
