What key metrics are displayed on an application's landing page in performance analysis?

1. User action duration

2. Active sessions

3. JS errors

4. Entry/Exit actions

The correct answer is: User action duration

The key metrics displayed on an application's landing page in performance analysis typically include those that directly reflect the user experience and the performance of the application. User action duration is particularly important because it measures how long specific actions take from a user's perspective, which directly affects user satisfaction and engagement. Analyzing this metric allows for early detection of potential performance issues, helping teams to optimize the application effectively. While other metrics such as active sessions, JavaScript errors, and entry/exit actions provide valuable insights, they do not primarily reflect the timing associated with user interactions, which is critical for performance monitoring. User action duration, in contrast, gives a clear indication of how well the application performs from the user's standpoint, making it a key focus on the landing page in performance analysis.
