Deep Link / Deferred Deep Link 深度连结

Deep Link 可以开启 app 的特定页面，而不仅仅是打开 app 首页而已。

In the context of mobile apps, deep linking consists of using a uniform resource identifier (URI) that links to a specific location within a mobile app rather than simply launching the app.

Deferred Deep Link (延迟深度连结)

与 Deep Link 的差异是，Deferred Deep Link 会先判断装置是否已经安装 app ，若没有安装便先引导到载点，安装完毕後再到指定的 Deep Link。根据不同的装置，引导开启的路径也都会不一样，像是 Android 系统会开启 Google Play Android; iOS 系统则是开启 App Store。

Deferred deep linking allows users to deep link to content even if the app is not already installed. Depending on the mobile device platform, the URI required to trigger the app may be different.
