Google Analytics 4 (GA4) has implemented a mandatory configuration requirement for custom events. This update ensures proper event attribution and eliminates the issue of (not set) values appearing in reports.
New Configuration Requirements
Properties must now have one of the following in place for custom events to function:
- A valid config command
- Installed Google tag on the web page
The update prevents custom events from being transmitted independently of tag configuration. This change addresses a significant reporting issue where events lacking proper configuration would result in incomplete attribution data.
Benefits for Analytics Users
This enforcement creates more reliable reporting by:
- Ensuring proper event attribution
- Reducing instances of missing data
- Improving overall data quality in GA4 reports
- Maintaining consistent tracking implementation
Web properties should verify their current configuration to ensure continuous custom event tracking. Those using custom events should confirm they have the necessary configuration elements in place to prevent any disruption in data collection.
