- **Day 7 behavior signals buying intent, not browsing.** Clicking contact information is a deliberate "reach-out" action — far stronger than content views or video watches; it typically maps to active evaluation or procurement interest. 点击联系方式属于主动“找上门”的采购信号，远强于浏览或看视频，通常意味着客户已进入评估或采购阶段。 - **Score logic: cumulative 55 + high-value action → predicted 76, crossing the 60 threshold.** The jump reflects both accumulated engagement (Days 1–6) and a weighted intent signal; AI upgrades C → B because the lead now shows readiness for human follow-up, not just nurturing. 55 分累计互动加上高权重意向行为，预测分升至 76，越过 60 分阈值，因此系统判定该客户已具备人工跟进价值，自动从 C 池升级到 B 池。 - **Triggered actions should be sales-grade, not marketing-grade.** On the C → B upgrade: auto-generate a tailored B2B proposal outline, create a follow-up task for the account owner within 24h, and notify sales with the behavior timeline. 升级动作应对接销售而非继续营销：自动生成定制化 B2B 方案框架、24 小时内为负责人创建跟进任务、并向销售同步行为轨迹。 - **Path to a 100-unit inquiry depends on the 120-point A-pool threshold.** B-pool actions should target proposal review, stakeholder mapping and a scoping call — each logged behavior compounds the score toward A, where enterprise-scale deals are typically handled. 能否转化为 100 人规模的询盘，取决于能否冲上 120 分的 A 池阈值；B 池阶段应聚焦方案评审、决策链梳理和需求确认会，每次互动累计加分，推动进入 A 池承接大单。 - **Business impact: shorter sales cycle and higher pipeline quality.** Early human intervention at the exact intent moment raises conversion probability and deal size, while keeping sales effort concentrated on genuinely qualified leads. 在意图最强的时点介入，可缩短销售周期、提升管道质量与客单价，同时让销售资源集中在真正合格的线索上。
