- **Day 7 behavior = buying-intent signal.** Clicking contact info means the lead moved from passive browsing to actively seeking a sales conversation—a strong intent marker, though a single click isn't yet commitment. - 点击联系方式是明确的购买意向信号：从被动浏览转向主动找销售沟通，但单次点击仍属早期意图。 - **Score math explains the C-Pool hold.** Cumulative 43 + this behavior → predicted 44, still below the 60 upgrade threshold. AI sees real interest but insufficient depth/velocity to justify B-Pool resources. - 累计43分加本次行为仅到44，低于60的升级线；AI认可兴趣但认为证据不足以占用B池资源。 - **Trigger lightweight, low-cost nurturing—not a full proposal yet.** Send a tailored training-solutions one-pager or case study, log a sales follow-up task, and set an auto-alert if score approaches ~55. - 触发轻量培育：发送定制方案简介/案例、生成销售跟进任务，并在接近55分时预警，暂不投入完整提案。 - **Protect pipeline quality and sales efficiency.** Holding in C avoids premature AE time on a 44-score lead; the click data enriches scoring so the next high-value action can tip it into B. - 保持C池可避免销售过早投入低分线索，同时点击数据丰富评分模型，下一次高价值行为即可推动升级。 - **Path to the 100-unit distribution inquiry.** A click alone won't convert a bulk order—sequence content toward volume/distribution use cases; once score crosses 60 (B upgrade), trigger a B2B proposal and AE follow-up to qualify the 100-unit scope. - 单次点击不足以转化批量订单：内容应导向分销/规模采购场景；分数过60升级B池后，再触发B2B提案与销售跟进，确认100套采购需求。
