Creating Google Analytics 4 custom dimensions and metrics allows you to easily access and use your event properties and user properties.
For example, without creating a custom dimension for your custom

By adding ‘affiliation’ as a custom dimension, you’ll be able to analyze subscription data and answer specific questions to your business’s needs.
