What is a Key Event in GA4?

Google Analytics 4 (GA4) has redefined conversion tracking by introducing the concept of key events. This update aligns conversion terminology and measurement more closely with other Google platforms, such as Google Ads. Previously known as Goals in Universal Analytics and Conversions in earlier versions of GA4, key events represent critical user actions that businesses track to measure success. This article will explain what a key event is in GA4, how to set one up, and the benefits of using key events for accurate performance measurement and enhanced marketing decisions.

Defining Key Events

A key event in GA4 is an event that measures an action particularly important to the success of your business. These events, formerly known as Goals in Universal Analytics and Conversions in earlier GA4 terminology, signify valuable interactions such as completing a purchase, signing up for a newsletter, or viewing a confirmation page. Key events help streamline conversion tracking and reporting across Google platforms, ensuring consistent and accurate performance measurement.

Setting Up a Key Event

To set up a key event in GA4, you need to create a specific event and then mark it as a key event. Here’s a step-by-step guide to measuring a key event when a user visits a confirmation page, like the URL http://www.example.com/contact-us-submitted.

Before You Begin:
You must have administrator or editor access to set up key events.

Step 1: Create an Event for the Confirmation Page

  1. Navigate to Events:
  • In the GA4 Admin panel, under the Data display section, click on Events.
  1. Create the Event:
  • Click on “Create event,” then click “Create.”
  • Enter the event name “generate_lead” in the Custom event name field.
  • In the Matching conditions section, set the condition “event_name equals page_view.”
  • Click “Add condition” and enter “page_location equals https://www.example.com/contact-us-submitted.”
  • In the Parameter configuration section, click “Add modification” twice to define required parameters.
  • For the first row, enter parameter “value” with the value “100” to define the lead value.
  • For the second row, enter parameter “currency” with the value “USD.”
  • Click “Create.”

Step 2: Mark the Event as a Key Event

  1. Navigate to Key Events:
  • In the GA4 Admin panel, under Data display, click on Key events.
  1. Mark the Event:
  • Click on “New key event.”
  • Enter the name of the new event, “generate_lead.”

Verify the Key Event:

  • After setting up, it may take a few minutes to a few hours for the configuration to apply.
  • Visit your site’s confirmation page and check the Realtime report’s Key events by Event name card for “generate_lead” to confirm its status.

Reporting on Key Events

Key Event Counts:

  • Access the Key events page in Admin to see a table listing each key event, the number of times users triggered it, and the associated value (if set).

User Acquisition:

  • Use the User acquisition report to select “generate_lead” from the Key events dropdown. This allows you to see traffic source dimensions associated with users’ first sessions that generated the most key events.

Attribution:

  • The Attribution paths report in Advertising helps you understand the customer paths leading to key events and how different attribution models distribute credit.
