Engagement Rate (GA4)

Engagement rate in Google Analytics 4 is the percentage of sessions classified as engaged sessions. Under Google's documented definition, a session is engaged when it lasts longer than 10 seconds, has a key event, or includes at least two page or screen views. The formula divides engaged sessions by all sessions for the selected reporting scope. This describes website or app engagement, not the number of social media likes, comments, or shares. A service page can have an encouraging engagement rate without generating qualified inquiries, so the metric should be considered alongside relevant actions such as completed quote forms. Changes in tracking setup or event definitions can also affect comparisons over time.
