**Day 7 Behavior → Score → Pool Upgrade → Action → Revenue Impact** - **Clicked contact info = direct purchase signal.** In B2B training sales, this is a "hand-raise" move—buyer actively seeks human contact, not just browsing. AI weights it heavily (+20 pts, 55 → 75). - 点击联系方式 = 明确的购买信号，属于主动寻求人工对接，AI 因此大幅加权（+20 分，55 → 75）。 - **C → B upgrade at threshold 60.** Cumulative engagement (55) + high-intent action (20) crosses the 60-point gate, confirming sustained interest, not a one-off click. - 累计互动 55 分叠加高意向行为 20 分，越过 60 分门槛，证明是持续兴趣而非偶发点击，因此 C 池升至 B 池。 - **Trigger precise actions: rep follow-up task + tailored proposal.** System should auto-assign a sales owner, schedule a discovery call within 24h, and send a B2B proposal scoped to team-training needs. - 系统应自动分配销售跟进人、24 小时内安排需求沟通，并推送针对团队培训场景的 B2B 方案。 - **Nurture toward B → A (threshold 120).** B pool rhythm: case studies, ROI/TCO content, and a pilot-workshop offer to keep score compounding. - B 池阶段用案例、ROI/成本效益内容和试点工作坊持续培育，推动分数迈向 120 分升 A 池。 - **Path to a 100-unit distribution inquiry.** Distribution buyers need scale credibility; timely human contact + proposal converts intent into a large-volume inquiry and shortens the sales cycle. - 分销型买家看重规模化能力，及时人工对接加方案能加速意向转化为大批量询单，并缩短成交周期。
