[GA4] Change the counting method of key events

Choose how many times you want Google Analytics to count a key event in a session

You can choose how many times Google Analytics counts a key event if someone triggers it more than once in a session.

About the counting methods

You can choose from these counting method options for a key event:

Once per event (Recommended): Counts a key event every time it's triggered. This option is recommended because it reflects the behavior of users on your site or app, and allows you to distinguish between sessions where multiple key events occurred and sessions where only one key event occurred.
Once per session (Legacy): Counts a key event only once within a particular session.

Example: If someone triggers a key event five times in a session, then:

Note: Default counting method

If you don't make a choice, Google Analytics will automatically use the default counting method. The default depends on how key events were created.

Once per session is the default counting method for all key events that were created from Universal Analytics goals:
- In an automatically created Google Analytics 4 property
- Using the goals migration tool in the Setup Assistant after April 2023
Once per event is the default counting method for all other key events

You can change the counting method setting at any time for any of your key events.

In Admin, under Data display, click Events.

Note: The previous link opens to the last Analytics property you accessed. You can change the property using the property selector. You must be a Marketer or above at the property level to choose a counting method.
In the Key events tab, click to the far right of a row.
Click Change counting method.
Select your preferred counting method.
- Note: If you can't select an option, you don't have the necessary permissions.
Click Save.

Note: Any changes to the counting method apply to future key events only, and won't apply to a key event's past data.
