[GA4] Enhanced measurement

 

Enhanced measurement affects only your web data streams.

Events you collect via enhanced measurement do not count toward the limit of 500 distinctly named 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 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 data will be collected. You can also turn off specific measurement options. Per our terms, you must ensure that no personally-identifiable information is sent to Google when you collect the data described in the following table.

The following table explains when events are triggered, and which parameters are collected for each event.

These events are collected only for websites.

 

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.

An advanced setting on this option controls whether the event is sent based on browser-history events. This measurement option listens for pushState, popState, and replaceState.		 page_location (page URL), page_referrer (previous page URL)

Scrolls

scroll

 the first time a user reaches the bottom of each page (i.e., when a 90% vertical depth becomes visible) No parameters are collected

Outbound clicks

click

 each time a user clicks a link that leads away from the current domain

link_classes, link_domain, link_id, link_url, outbound (boolean)

Site search

view_search_results

 each time a user performs a site search, indicated by the presence of a URL query parameter

By default, the event is triggered based on the presence of one of the following 5 parameters in the URL:
  • q
  • s
  • search
  • query
  • keyword
You can optionally configure this option to look for search terms in other parameters.		 search_term, optionally ‘q_<additional key="">’ (where <additional key=""> matches an additional query parameter you specify to be collected under advanced settings)

Video engagement

video_complete

 For embedded YouTube videos that have JS API support enabled, the following events are triggered:
  • video_start when the video starts playing
  • video_progress when the video progresses past 10%, 25%, 50%, and 75% duration time
  • video_complete when the video ends

video_current_time, video_duration, video_percent, video_provider, video_title, video_url, visible (boolean)
