Define Engagement Metrics for TikTok/Reels

To measure deep engagement beyond views, I would prioritize Completion Rate, Save-to-View Ratio, and Daily Active Return Rate. First, Completion Rate is critical because it directly signals whether the content hooks the user immediately and sustains attention until the end. On Reels, a high completion rate tells the algorithm to push the video further, creating a positive feedback loop for both creator and viewer. It measures the depth of immersion better than a mere impression. Second, the Save-to-View Ratio is a powerful indicator of perceived value and future intent. Unlike likes, which can be impulsive, saving a reel implies the user finds it useful enough to reference later. This metric correlates strongly with long-term retention and suggests the content has utility beyond entertainment, fostering a habit-forming relationship with the platform. Third, Daily Active Return Rate measures the stickiness of the experience. Addiction isn't just about watching one video; it's about the compulsion to return. If users consistently come back within 24 hours after viewing specific content types, it validates the platform's ability to create a compelling daily routine. By focusing on these three, we move from measuring exposure to measuring genuine behavioral dependency and value delivery.
