# PostHog Analytics Integration - Team Review Guide
## 🎯 Quick Summary
We've added PostHog analytics alongside our existing Google Analytics to provide advanced user behavior tracking, funnel analysis, and A/B testing capabilities for the Desktop Commander landing page.
## 🔍 What to Review
### Key Files Changed
1. **`docs/index.html`** (lines ~60-90): PostHog SDK integration
2. **`docs/js/analytics-tracking.js`** (extensive enhancements): Dual tracking functionality
### Safety Features ✅
- **Production-only tracking**: PostHog only activates on desktopcommander.app
- **Zero GA interference**: All existing Google Analytics functionality preserved
- **Privacy-compliant**: EU hosting, GDPR-friendly settings
- **Performance optimized**: Async loading, DNS preconnect
## 📊 New Analytics Capabilities
### User Journey Tracking
```javascript
// Example: Track complete installation funnel
installation_funnel {
step: "method_selected",
method: "Docker Install",
success: true,
funnel_stage: "method_selected_Docker Install",
step_number: 4
}
```
### Performance Monitoring
```javascript
// Example: Core Web Vitals tracking
performance_metric {
metric_name: "fid",
metric_value: 304,
context: "core_web_vital"
}
```
### Enhanced User Engagement
```javascript
// Example: Scroll depth tracking
user_engagement {
milestone: "scroll_depth",
details: "50%",
scroll_depth: 50,
time_on_page: 41
}
```
