High push volume with low CTR suggests poor targeting or weak creative; users receive many prompts but ignore them. Low volume with high CTR implies tight audience fit or compelling messaging, but limited scale. Measuring both together reveals efficiency: optimized pushes raise CTR without unnecessary sends, while excessive frequency can erode engagement even if impressions grow. Segmenting by time, message type, and user intent uncovers which pushes trigger immediate action versus those ignored or dismissed. A/B testing headlines, timing, and deep links ties specific changes to CTR shifts.
