Marcus 需要向公司的领导团队汇报一项 B2B 推广活动的结果。他准备的幻灯片只展示了点击率和视频完整播放量。他的经理提醒他，领导层想要了解的是业务成效。Marcus 应该如何改进他的演示文件？

The correct answer emphasizes focusing on business-relevant KPIs and using multi-touch attribution. Leadership teams are primarily concerned with business outcomes, not just superficial engagement metrics like click-through rates (CTR) and video completion rates. Multi-touch attribution provides a more comprehensive view of how different marketing touchpoints contribute to conversions throughout the customer journey, offering insights into the true impact on business results. The first incorrect option suggests sticking to superficial data, which directly contradicts the need for business impact. The third incorrect option focuses only on brand awareness, which might not be the sole or most important business outcome for leadership. The fourth incorrect option, using last-click attribution, is too simplistic and doesn't provide a full picture of the buyer's journey, potentially misrepresenting the value of earlier touchpoints.
