**Day 7 Lead Nurturing Read — Global Skills** - **High-value behavior:** A callback request is an explicit buying signal — the lead is self-identifying as sales-ready and requesting human contact, not just browsing. This is far stronger than passive content consumption. 中文：主动预约回电是明确的购买信号——客户自己表态“准备好谈”，价值远高于浏览或看视频等被动行为。 - **Why still in C Pool:** Day 7 predicted score is 53, below the 60 threshold. AI is signaling **rising intent but not yet qualified** — momentum is building (15 → 45 → 53), so no upgrade is correct; premature promotion would inflate B pool with unready leads. 中文：预测分 53 未达 60 门槛。AI 判断意向在上升但尚未达标；此时升级会把未成熟线索塞进 B 池，拉低整体转化率。 - **Triggered actions:** (1) Create a success-team callback task with 24–48h SLA; (2) send a tailored B2B proposal / capability deck tied to their stated need; (3) log the callback as a scoring event so the next interaction can push score past 60 → C→B upgrade. 中文：48 小时内派发成功团队回电任务；发送针对性 B2B 方案；将回电记录为加分事件，推动下次互动突破 60 分完成 C→B 升级。 - **Path to 100-unit inquiry:** A qualified callback + proposal accelerates the buying committee review; once upgraded to B, sales follow-up cadence tightens, shortening the cycle to a formal 100-unit distribution quotation. 中文：回电+方案加速采购委员会评审；升级到 B 后跟进节奏收紧，更快推进到 100 套分销正式报价。 - **Business impact:** Treat the callback as a **high-intent flag**, not a closed deal — it converts a warm C lead into a measurable pipeline opportunity without over-investing sales time pre-qualification. 中文：把回电视为高意向标记而非成交——在不浪费销售资源的前提下，把温线索转为可衡量的商机。
