This happens when your report exceeds the sampling threshold , which is 500K sessions for standard GA users and 100M for GA360 users. Why Does Google Analytics Use Data Sampling? ✅ Performance Optimization: Processing large datasets requires time and computing power. Sampling speeds up report generation. ✅ Complex Query Handling: Custom reports, segments, and long date ranges can trigger sampling to make analysis quicker. ✅ Platform Limitations: Free GA users have r...
