- **Why Day 7 is high-value:** A callback request is explicit buying intent, not passive browsing. It moves the lead from "marketing-qualified" to "sales-ready" and signals a real project with decision authority or influence. **为什么第7天的行为价值高：** 主动预约回电是明确的采购意向，而非被动浏览。它把线索从市场合格升级为销售就绪，说明背后有真实项目和决策影响力。 - **Why it stays in C Pool:** One intent signal adds only ~3 points (10 → 13), far below the C→B threshold of 60. AI weights cumulative evidence—content depth, repeat visits, video completion—so a single call request isn't enough to reclassify. **为什么仍在C池：** 单一意向信号只加约3分（10→13），远低于C→B的60分门槛。AI看重累积证据（内容深度、复访、视频观看），一次回电请求不足以升级。 - **Actions to trigger now:** Route a same-day callback to the success team, log a qualified sales follow-up task with a 24h SLA, and send a tailored 100-unit training proposal plus case study. Flag the account for score monitoring. **当前应触发的动作：** 当天由成功团队回电，创建带24小时SLA的销售跟进任务，并发送针对100单元需求的定制方案与案例。同时标记该账户加强分数监测。 - **Path to the 100-unit deal:** The callback confirms scale intent; pairing a proposal with follow-up lets sales validate budget and timeline. Continued engagement should push the score toward B, unlocking stronger nurturing and higher pipeline quality. **如何促成100单元订单：** 回电确认了规模意向；方案加跟进帮助销售验证预算与时间表。持续互动将推动分数向B升级，带来更强培育和更高管道质量。 - **Business impact:** This is about sales efficiency—AI prevents premature upgrades while ensuring high-intent signals get immediate human follow-up, improving conversion rate and protecting deal size. **业务影响：** 核心是销售效率——AI避免过早升级，同时确保高意向信号得到即时人工跟进，从而提升转化率并保障订单规模。
