Google Analytics 4 Automatic Events | 2024 Complete List 

Google Analytics allows you to track automatically collected events and custom events. Custom events can be split into recommended and user-defined events. 

Automatically collected events can be broken down into the ones that GA4 collects automatically after adding the code on the website, and you can’t disable them, and those you can turn on and off using the Enhanced Measurement interface in Google Analytics 4. Enhanced Measurement events are activated automatically as well once you create a GA4 property.  

This article will list all automatically collected events that Google Analytics measures once you add a GA4 snippet code to your website or app. These events can give you first insights into users’ behaviour and company well-being. 

GA4 Automatic Events for Mobile and Web

As mentioned above, for Google Analytics 4 to collect automatic events, you must place a GA4 code on your website or app. After it’s there, depending on whether you use a website or app, GA4 starts to collect the following events with the parameters. 

Note: All events are collected in the table below and updated regularly after every new GA4 update. You can turn the events off in Enhanced Measurement ( GA4 – Admin – Data Streams – Data Stream Details – Enhanced Measurement) are marked as “True” in “Enhanced Measurement Support” column.

Final Word 

Unlike Universal Analytics, Google Analytics 4 collects way more automatic events. Adding a small piece of code to your website or application code lets you get information about users, sessions, page views, page scroll, video and page engagement, file downloads, form interactions and more. This makes Google Analytics 4 easy to install and more affluent in data than Universal Analytics.

Frequently Asked Questions

What are GA4 automatic events?

These are automatically collected events by Google Analytics 4 that the tool can measure by only placing the primary snippet on a website or mobile app code. Some of them are session_start, page_view, user_engagement and others.

What events does GA4 collect automatically?

GA4 collects more than 30 events automatically. Some of them are: page_view, session_start, view_search_results, video_progress, video_start, video_complete, user_engagement, scroll, screen_view, notification_receive, os_update, notification_foreground, notification_dismiss, in_app_purchase, form_start, form_submit and many others.

Does GA4 automatically track clicks?

Google Analytics 4 only tracks outbound clicks automatically. Outbound clicks are clicks on links with a domain different from your website.  If you want to track every click on your website, set it up using Google Tag Manager.

How do I turn off automatic events in GA4?

Though you can disable several automatic events in GA4 -> Admin -> Data Streams -> Data Stream Details -> Enhanced Measurement, there are several events that you can’t turn off, for instance, “session_start” event.
