如果您想分析公司网站以及两个单独的应用（分别是 iOS 版和 Android 版）的事件和用户情况，您应该如何设置自己的账号？

The correct approach is to set up a single Google Analytics 4 (GA4) property. Within this property, you'll create one web data stream for your company website and two app data streams: one for your iOS application and one for your Android application. This consolidates all data (website, iOS app, Android app) into one property, allowing for a unified view of user behavior across all platforms using GA4's cross-platform tracking capabilities. Incorrect options suggest creating multiple properties for different platforms. While technically possible, this fragments your data, making it difficult to analyze combined user journeys and understand overall engagement across your ecosystem. GA4 is designed for cross-platform measurement within a single property.
