Google Analytics 4 (GA4) is now the standard, and with each update, it becomes more powerful—and more complex. Most businesses are using GA4 with default settings, leaving valuable data untracked and optimization opportunities undiscovered. Here’s the essential GA4 configuration checklist for 2026.
Why GA4 Configuration Matters
Default GA4 setup tracks page views and basic events. But the real power lies in custom events, conversions, and audiences that let you understand and act on user behavior. Without proper configuration, you’re flying blind.
Essential Account Structure
Account > Property > Data Streams
One property per website or app. Multiple streams only when you need unified reporting across properties.
Data Streams
- Web stream for your website
- Add Measurement Protocol for server-side tracking
- Mark each stream clearly (production, staging)
Events Configuration
Enhanced Measurement (Enable These)
- Page views: Yes (automatic)
- Scrolls: Yes—when users scroll 90% of page
- Outbound clicks: Yes—track links leaving your site
- Site search: Yes—if you have internal search
- Video engagement: Yes—for embedded videos
- File downloads: Yes—PDFs, downloads
Custom Events to Create
- Form submissions: track every form field submission
- Phone calls: clicks on tel: links
- Email clicks: clicks on mailto: links

- Purchases
