GA4: Fix Thresholding Applied & Missing Small Audience Data

Exact Error Message:Thresholding applied: Google Analytics has applied thresholding to this report or exploration.

Why This Error Occurs (Root Cause Analysis)

Google Analytics 4 applies data thresholding to prevent individual user identification when reports include Google Signals (demographic and interest data) with small user sample sizes.

Step-by-Step Resolution Guide

Follow these verified steps in sequence to isolate and eliminate the error condition:

1
Switch Reporting Identity in GA4 Admin: Navigate to Admin > Reporting identity > Click "Show all" > Select "Device-based" identity.
2
Device-based identity evaluates client IDs without Google Signals, immediately removing thresholding icons and restoring row-level reporting data.
3
Expand date ranges to aggregate larger sample cohorts above Google's privacy threshold limits.
