What Is Google Analytics 4?
Google Analytics 4 (GA4) is Google’s modern analytics platform designed for:
- Website measurement
- Mobile app tracking
- User behavior analysis
- Conversion monitoring
- Marketing optimization
Unlike Universal Analytics, GA4 tracks everything as events. A page view, a button click, a video play, and a purchase are all recorded as individual events.
Why GA4 Matters in 2026
The internet has changed dramatically.
Users now interact across:
- Mobile devices
- Desktops
- Tablets
- Applications
- Multiple channels
Traditional session-based tracking became increasingly limited.
GA4 addresses these challenges through:
Event-based measurement
Privacy-first architecture
Cross-device tracking
AI-powered insights
Predictive analytics
Modern businesses require deeper understanding of customer journeys.
Universal Analytics vs GA4
The transition from UA to GA4 represents a fundamental shift.

Major Differences
| Feature | Universal Analytics | GA4 |
|---|---|---|
| Data Model | Sessions | Events |
| Cross-Platform Tracking | Limited | Advanced |
| AI Insights | Basic | Strong |
| Predictive Metrics | No | Yes |
| Privacy Features | Limited | Enhanced |
| BigQuery Export | Premium | Free |
Understanding the Event-Based Data Model
The most important concept in GA4:
Everything is an event.
This mental model simplifies the platform enormously. Many analysts report that understanding this shift is the key to becoming comfortable with GA4.
Examples of Events
Page View
page_viewScroll
scrollPurchase
purchaseVideo Engagement
video_startForm Submission
generate_leadEvery business action becomes measurable.
Event Parameters
Events contain additional information.
Example:
purchase
Price = ₹5000
Product = Laptop
Currency = INRParameters provide context.
Without parameters, events lose meaning.
Four Categories of GA4 Events
Automatically Collected Events
GA4 tracks these immediately:
first_visit
session_start
page_view
user_engagement
No configuration required.
Enhanced Measurement Events
These require a simple toggle.
Examples include:
Scroll tracking
Outbound clicks
File downloads
Video engagement
Site searches
Automation saves significant implementation time.
Recommended Events
Google suggests standardized names:
Examples:
