[GA4] Enhanced measurement events

Enhanced measurement lets you measure interactions with your content by enabling options (events) in the Google Analytics interface. No code changes are required. When you enable these options for a web data stream, your Google Analytics tag starts sending events right away.

Before turning on the enhanced measurement feature, be sure you understand each option and what enhanced data will be collected. You can also turn off specific measurement options in settings.

You're required to ensure that no personally identifiable information is collected.

Enable or disable enhanced measurement events

1. In Admin, under Data collection and modification, click Data streams.
   Note: The previous link opens to the last Analytics property you accessed. You can change the property using the property selector. You must be an Editor or above at the property level to enable or disable enhanced measurement events.
2. Click the name of your data stream.
3. Under Enhanced measurement, slide the switch On to enable all options.
   Click to edit individual options as needed.

If you use the Google tag on your website, you also need to make sure that each event is enabled for automatic event detection for your Google tag. By default, all event types are enabled. Learn more about your Google tag settings

Events measurement and parameters

The following table explains when events are triggered, and which parameters are collected for each event. You can find enhanced data about each triggered event in the Events report within the Engagement topic. Click the event name in the report for more information on the event.

To understand each event parameter listed below and how each parameter updates a dimension or metric in Google Analytics, see Google Analytics event parameters.

Measurement option / event	Triggered...	Parameters
Page views page_view	each time the page loads or the browser history state is changed by the active site This event is collected automatically. You cannot turn off collection.

The event populates the Views metric. The parameters populate the following dimensions: Page location (from page_location) Page referrer (from page_referrer)	page_location (page URL), page_referrer (previous page URL)

The search_term parameter populates the Search term dimension.	search_term, optionally ‘q_<additional key="">’ (where <additional key=""> matches an additional query parameter you specify to be collected under advanced settings).
