What you gain
- ✓No data sampling on reports exceeding Google's thresholds
- ✓Full ownership of visitor data without Google's data policies
- ✓No thresholding that hides data points for privacy
- ✓Lightweight tracking scripts that don't slow page loads
What you give up
- △No native integration with Google Ads for conversion tracking
- △No BigQuery export for free SQL access to raw GA4 data
- △No machine learning predictions (purchase probability, churn risk)
- △No cross-device user tracking via Google Signals
Switching Cost
GA4's real lock-in is the Google Ads integration. If you're running paid campaigns and optimizing on GA4 conversion events, switching analytics means rebuilding your entire ad attribution pipeline. Teams that only use GA4 for traffic stats can switch in an afternoon with a script tag swap. E-commerce teams with enhanced measurement, custom dimensions, and Google Ads conversion imports should budget 1-2 weeks. The hidden cost is losing the free BigQuery export, which many teams build internal dashboards on top of.
