The data you see in your Google Analytics 4 reports comes from events that are triggered as users interact with your website and/or app. For example, a
page_view event is triggered each time a user views a page on your website.
Many events (including
page_view) can be collected without you adding code. These events may be sufficient for your needs.
- Automatically collected events are collected automatically with basic data collection.
- Enhanced measurement events are collected automatically if you have enabled enhanced measurement. You can enable/disable the collection of individual enhanced measurement events via the Admin page within your Google Analytics 4 property.
However, if you have more advanced data collection needs, you can add code to collect additional events (or create them via the user interface).
- Recommended events are events that you implement yourself, but that have Google-predefined names and parameters. Recommended events unlock existing and future reporting capabilities not available for custom events (events that you name yourself). Here are the events recommended for all properties, online sales, and games.
- Custom events are events that you name and implement yourself. Before implementing a custom event, check that there is not an automatic, enhanced measurement, or recommended event that already provides what you need. Learn how to implement custom events for web and app.
