Short answer
Engagement rate is a metric with two common meanings. In Google Analytics 4, it is engaged sessions divided by total sessions. On social media platforms, it is interactions such as likes, comments, and shares divided by reach or impressions. In both cases, it indicates how actively an audience responds to content.
