- **High-value signal:** Clicking contact info is an explicit buying-intent action—it moves the lead from passive content consumption to active vendor evaluation, a much stronger signal than views or video watches. 高价值信号：点击联系方式是明确的购买意向动作——客户从被动浏览转向主动评估供应商，比单纯浏览或看视频强得多。 - **Why still in C Pool:** Day 7 predicted score is 54, below the 60 C→B threshold. The AI treats this as rising intent but not yet qualified; upgrade logic is threshold-based, not single-behavior-based. 仍在 C 池的原因：第 7 天预测分 54，低于 60 的 C→B 阈值。AI 视为意向上升但尚未达标；升级按分数阈值判断，不因单一行为直接升级。 - **Nurturing actions to trigger:** Send a tailored B2B training proposal (100-seat distribution scope), create a sales follow-up task within 24–48h, and push one more high-intent content asset to close the 6-point gap. 应触发的培育动作：发送定制化 B2B 培训方案（100 单位分销范围）、24–48 小时内创建销售跟进任务、再推一份高意向内容以补齐 6 分差距。 - **Business impact:** Faster sales response on a contact-click lead lifts conversion probability; the proposal frames the 100-unit distribution inquiry early, protecting deal size and shortening the pipeline cycle. 业务影响：对点击联系方式的线索快速响应可提升转化概率；提前用方案锚定 100 单位分销询盘，保障成交规模并缩短销售周期。
