Hourly user age—tracking the time users spend interacting with push ads or how recently they engaged—is important for optimizing campaign performance. Understanding user activity patterns by hour helps advertisers schedule push notifications when their target audience is most active and receptive, increasing the likelihood of clicks and conversions. It also aids in segmenting users by engagement recency, allowing for tailored messaging; for example, fresh users might receive introductory offers, while older users get reminders or retargeting ads. Hourly data helps prevent ad fatigue by limiting notification frequency during low-engagement periods. Overall, leveraging hourly user age improves relevance and timing, reducing wasted impressions and enhancing ROI in push ad campaigns through more precise targeting and better user experience.
