1. **Why "Requested Callback" is high-value behavior** It signals strong purchase intent — the lead is actively seeking human interaction, not just consuming content. In B2B, this directly correlates with higher close rates. **要求回电是高价值行为**，代表客户主动寻求深度沟通，B2B中此类行为与成交率强相关。 2. **Why AI keeps this customer in C Pool** Current score (22) is far below the C→B threshold (60). One strong signal isn't enough; the model requires sustained engagement or higher-intensity behaviors to upgrade. **当前分数22，远低于升级阈值60**。单次高价值行为不足以触发升级，系统需积累更多可信信号。 3. **Precise actions to trigger** - Immediately assign a success team callback task (within 24h) - Send a tailored capability deck focused on their visited content - No proposal yet — scoring too low for sales handoff **触发动作**：24小时内安排成功团队回电、发送针对性能力介绍、暂不发送提案（分数不足）。 4. **How this supports 100-unit conversion** High-intent callback + tailored content accelerates trust; if callback reveals budget or timeline, this lead jumps to B pool, triggering formal proposal and sales follow-up, unlocking volume inquiry. **回电+精准内容加速信任建立**；如确认预算/时间表，可升级至B池并触发正式提案与销售跟进，推动百套采购机会。
