Measuring push traffic campaign performance often misleads beginners when they focus on CTR instead of post-click conversion quality and revenue per user. High click-through rates can look exciting, but they often hide low-intent traffic that never converts into sales or meaningful engagement downstream. Tracking only CPM or CTR is like heatmaps without context, showing activity but not whether users actually become paying customers. Instead, monitoring cost per conversion and return on ad spend reveals whether scaling is sustainable or quietly burning budget.
