- **Day 7 “clicked contact info” is a strong buying signal.** It shows the lead moved from passive interest to active seller-contact intent, which usually correlates with higher sales acceptance and faster follow-up. - 中文：第7天点击联系方式是明确的高意向信号，说明客户从“看看内容”转向“准备接触销售”，通常会带来更高的跟进成功率和转化速度。 - **AI upgrades C → B because cumulative engagement (57) plus high-intent action pushed predicted score to 88, above the 60 threshold.** The system is not just counting activity; it is weighting late-stage behavior more heavily. - 中文：AI把客户从C升到B，是因为前6天累计57分，加上第7天高意向行为后，预测分达到88，超过60分升级线；系统更看重后期高价值行为，而不是单纯看活跃次数。 - **Triggered actions should be B2B proposal preparation + sales follow-up task.** Specifically: route to sales owner, send tailored training proposal, schedule follow-up within 24 hours, and add to B-pool nurture cadence. - 中文：应触发B2B方案准备和销售跟进任务，包括分配给销售负责人、发送定制培训方案、24小时内安排跟进，并纳入B池培育节奏。 - **This improves pipeline quality and shortens the path to a 100-unit inquiry.** By upgrading at 88, sales can engage while intent is hot, increasing the chance of converting into a bulk distribution conversation. - 中文：这能提升商机质量并缩短转化为100套分销询盘的路径；在88分时升级，销售可在意向最强时介入，提高批量分销洽谈的成交概率。 - **Next threshold: B → A at 120.** To reach A pool, the system should watch for deeper actions such as proposal download, pricing request, meeting booking, or multi-stakeholder engagement. - 中文：下一阶段是120分从B升到A；系统应重点观察更深入的行为，如下载方案、询价、预约会议或多角色参与，以判断是否进入A池。
