Understanding Data Thresholds in Google Analytics 4

This article introduces a magical data privacy protection mechanism in Google Analytics 4 —— Data Thresholds.

What is Data Thresholds

The data threshold is defined by the GA4 system, and the user cannot modify it, and does not know the specific value.

When will the Data Thresholds be Triggered

If you have Google Signal turned on, select “Blended” or “Observed ” in “Reporting Identity”.
