  • Key events replaced conversions with the latest update of GA4.

What are Key Events in GA4?

Key events are just like any other event in your reports, but in Google Analytics 4, they're defined to be part of the "Key Events" metric (which used to be called "Conversions").

Conversions (key events) represent the crucial actions that happen on your site such as purchases, form submissions etc. Actually, there's no definitive list of key events here because they can vary according to your business objectives.

You must set up Key Events for your most important actions. For example, Google Merch Store included these three important events for their website:

  • purchase (automatically configured as conversion in GA4)
  • add_to_cart
  • view_item

Many standard reports in GA4 include Key Events column like above. Under key events, you can select a specific event. It counts the number of times users have triggered key events on your website.

You can build a custom report by using Key Events metrics (Key events, Session key event rate, and User key event rate).

How to Configure Key Events in GA4?

You can turn any event into a key event. To track a key event, simply create or find an event that measures the action, and then mark it as a key event.

Once you've marked it as a key event, you'll be able to see how many users actually perform the action.

To use an event as a Key Event, you can follow these simple steps:

All the events that you previously marked as conversions in GA4 will now be Key Events. They don't require reconfiguration.

Example Key Events (Custom):

Mark as conversion / key event
Mark as conversion / key event

Note : If the Key Event you want hasn't been collected yet, click New key event in the top right corner. Enter the event name exactly as GA4 will receive it. Once collected, the event will appear in your reports' Key Event metrics.

In this table, you can also view event count and value change. If you click on the three dotted sign, you can change your key event counting method to "Once per event" or "Once per session". Thus, you're able to decide how to count a key event.
