Key metrics for evaluating player engagement in gaming encompass several quantitative and qualitative measures that provide insights into how players interact with a game. Core metrics include player retention rates, which indicate how many users return to the game after their initial play, and session duration, reflecting how long players engage during each gaming session. Daily Active Users (DAU) and Monthly Active Users (MAU) are crucial for measuring the game's overall reach and community activity. In-game behaviors, such as frequency of play, conversion rates (for monetized games), and completion rates for levels or challenges, further illustrate engagement depth.
