Derek 团队正在评估近期一项 B2B 推广活动的效果。演示请求等漏斗底部的指标表现强劲，领导层建议将下个季度的大部分预算转移到需求挖掘上。Derek 应该指出什么？

Investing solely in bottom-of-funnel (BoFu) demand generation, like requests for demos, while showing immediate strong performance, risks neglecting top-of-funnel (ToFu) and middle-of-funnel (MoFu) activities. ToFu and MoFu efforts, such as brand awareness and lead nurturing, are crucial for building a sustainable pipeline of future leads. Without these earlier stages, the pool of potential customers for BoFu activities will eventually dry up, leading to missed long-term opportunities and an inconsistent sales pipeline. Therefore, a balanced approach across all funnel stages is essential for sustained growth.
