A tracked install refers to the successful download and opening of an app by a user for the first time as tracked by the 3rd party SDK.
Tracked installs are a crucial component of the user acquisition cycle, and 每次安装成本（CPI） 广告是目前用户获取的最流行方法，所以准确监测和量化安装数量至关重要。
为什么追踪安装重要？
追踪安装在移动营销中发挥着至关重要的作用，原因有几个。首先，追踪安装这一指标帮助广告主确定广告的有效性。此外，通过监测应用程序中的安装情况，广告主可以了解营销活动回本时间，再以此来调整推广和变现的付款方案。
追踪安装和自然安装有什么区别？
与追踪安装不同，Tenjin 中的 organic install 自然安装指的是无法归因于特定安装源的安装。这意味着，任何不被视为追踪安装的安装，即不来自效果营销或广告的安装，都被认为是自然量。自然安装很有价值，因为这是用户自己发现应用，并在没有提示的情况下自发进行的下载。这些用户对产品或服务的忠诚度往往更高，并且更可能留下来，是移动营销的重要组成部分。
Tenjin 如何计算追踪安装和自然安装？
Tenjn tracks organic installs on its dashboard, free of charge. We allow for a cohort analysis, segmentation by country and platform, and an analysis of events performed in-app to better understand users, whether organic or not. Tenjin's install tracking tool helps marketers properly attribute where paid installs come from, and identify when un-attributed or organic installs take place. A high number of installs, as well as a healthy user engagement, demonstrates that an app is performing well. And by properly attributing installs, businesses can work out whether they have delivered the necessary user quality on behalf of the business.
