如何定义“线索挖掘”？

Lead generation, or "线索挖掘," is correctly defined as occurring in the later stages of the marketing funnel, with the primary goal of collecting potential buyers' contact information. This is because lead generation focuses on identifying and capturing specific individuals who have shown interest, moving them closer to a purchase. The other options are incorrect: "提升参与度" (increasing engagement) is a broader goal throughout the funnel, not specific to lead generation. "调动潜在买家的热情，而非获取其详细信息" (generating enthusiasm without collecting detailed information) describes earlier-stage awareness or interest activities, not lead generation itself. "提升品牌认知度" (increasing brand awareness) is an even earlier-stage marketing objective.
