Best Practices for Mobile App Analytics

1. Plan Your Event Taxonomy

Before implementation, map out your event strategy:

Start with business goals (acquisition, engagement, monetization, retention)
Define key metrics for each goal
Map events and parameters to each metric
Use consistent naming conventions (snake_case)

2. Use User Properties for Segmentation

Set user properties to segment your audience:

User type: free, premium, trial
Subscription tier: basic, pro, enterprise
User preferences: theme, notification settings
Account age: new, active, churned

3. Set Up Enhanced Measurement

Enable enhanced measurement for automatic tracking:

Screen views
Scroll tracking
Outbound clicks
Site search
Video engagement
File downloads

4. Implement Error Tracking

Use Firebase Crashlytics alongside GA4:

Automatic crash reporting
Breadcrumb tracking
Crash-free users metric
Integration with GA4 for crash correlation

When to Consider Alternatives

While GA4 is excellent for many use cases, consider alternatives when:

You need user-level analysis with detailed user profiles → Mixpanel or Amplitude
You need session replay and heatmaps → Smartlook or UXCam
You need real-time product analytics → Amplitude or Heap
You need A/B testing built-in → Mixpanel or Firebase Remote Config
You're concerned about privacy and data ownership → PostHog or Matomo
