How many custom dimensions can I have in standard GA4?

Standard GA4 properties are limited to 50 event-scoped, 25 user-scoped, and 10 item-scoped custom dimensions.

Can I create calculated metrics in GA4?

Yes, GA4 allows you to create up to 5 calculated metrics in standard properties, which are derived from existing metrics using mathematical operations.

What is the difference between event scope and user scope?

Event-scoped dimensions apply only to the specific event they were sent with, while user-scoped dimensions persist and apply to all events associated with that user session.

Do I need to register parameters before they appear in reports?

Yes, while parameters are collected by GA4, they remain invisible in standard reports and Explorations until they are manually registered as custom dimensions.

Why aren't my custom dimensions showing up in GA4 reports?

Custom dimensions typically require a 24-48 hour processing window to populate in standard reports after they have been registered in the Admin panel.

Analytics & Monitoring

Guides the implementation, registration, and troubleshooting of event, user, and item-scoped custom dimensions in Google Analytics 4.

About

This skill provides a comprehensive framework for extending Google Analytics 4 data beyond default parameters by implementing custom dimensions and metrics. It guides developers through the entire lifecycle of custom data, from instrumenting code and verifying parameters in DebugView to registering event-scoped, user-scoped, or item-scoped dimensions in the GA4 Admin panel. By addressing common pitfalls like processing delays, naming conventions, and quota limits, this skill ensures that custom business data is correctly captured, processed, and made available for standard reporting and Explorations.
