竞品分析的第一步不是研究细节，而是确认目标。本文将拆解三类竞品的定义与识别方法 ——从直接抢夺用户的正面竞争者，到分流注意力的间接对手，再到可能跨界打击的潜在威 胁。掌握这套分类逻辑，你的市场分析才能精准打击要害。 上一篇我聊了竞品评测的四个维度。但在动手分析之前，还有一个更前置的问题：你选的竞品对吗？ 我见过一种情况：分析做得很细，四个维度全覆盖，图表也很漂亮，结果老板看完说"这几个产品和我 们不是一个赛道的啊"。整份报告直接作废。 竞品选错，后面全是无用功。所以这篇我专门聊怎么选竞品。 先搞清楚一个概念：什么叫竞品？ 竞品就是"竞争产品"，但竞争不是只有一种。 很多人理解的竞品就是"做一样东西的产品"，太狭隘了。实际上，只要会分走你用户的时间、注意力、 预算的产品，都可能是你的竞品。 在AI产品领域，我把竞品分成三类：直接竞品、间接竞品、潜在竞品。分清楚这三类，你的竞品选择 就不会跑偏。 三类竞品的定义和区分方法 2.1 直接竞品：用户会在你们之间"二选一" 直接竞品的特征是：同一市场、同一赛道、目标用户高度重合、核心功能高度相似。用户在选择时，会 直接把你们放在一起比较。 判断标准： 目标用户是不是同一 ...
