Google Analytics 4 - Google's current analytics platform using event-based tracking.

Why It Matters

GA4 is Google's standard for analytics, replacing Universal Analytics. Its event-based model offers more flexibility for tracking complex user journeys. For ecommerce, GA4's enhanced measurement, cross-platform tracking, and BigQuery integration unlock insights impossible in UA.

Practical Example

Scenario

A multi-channel brand uses GA4 to unify web and app analytics for a complete customer view.

Calculation

Web-only view: 2.3 sessions per purchase. GA4 cross-platform: 4.1 touchpoints per purchase (includes app engagement). Attribution accuracy improves 35%

Result

Understanding the true cross-platform journey reveals that app users are 2.4x more valuable—shifting investment toward app promotion.

Pro Tips

  • 1Set up enhanced ecommerce events: view_item, add_to_cart, begin_checkout, purchase
  • 2Use audiences in GA4 and export to Google Ads for better targeting
  • 3Connect GA4 to BigQuery (free for reasonable volume) for advanced analysis
  • 4Create custom events for your specific business actions (product quiz completion, review submission)

Common Mistakes to Avoid

Using default setup without configuring ecommerce events properly
Ignoring the exploration reports—they're where GA4's power lives
Not setting up conversions (goals) for key business actions
