If you are looking for an effective way to measure custom events in Google Analytics 4 (GA4), you have come to the right place. Measuring events is essential to understanding your users' behavior and optimizing your marketing strategies. In this step-by-step guide, I'll show you how you can set up and analyze these events with GA4 to gain valuable insights into your web interactions and improve the performance of your campaigns.
1. Define the Objective and the Customized Event
The first step to measuring custom events in GA4 is to clearly define the objective What action do you want to track: button clicks, user registrations or file downloads? Setting a goal will allow you to identify which events are relevant and configure them accordingly.
Once defined, assign a clear and descriptive name to the event, such as user_registration o clic_boton_whatsapp. This step is essential because it will allow you to easily identify events in GA4 reports.
2. Create the Custom Event in GA4
Now that you are clear about the event you want to track, it's time to set it up. There are several ways to send custom events to GA4, and here I will show you the most common ones:
Before we continue, if you want to understand how to take your measurement a step further and avoid data loss due to blockers, cookie restrictions or attribution issues, I recommend you read our guide about Google Analytics 4 Server-Side Tracking.

Using Google Tag Manager (GTM)
This is the most flexible and recommended option for most cases. To create a custom event with GTM, follow these steps:
- Make sure you have installed Google Tag Manager on your website and that your property of GA4 is correctly configured.
- In GTM, create a new tag of the type «Google Analytics: GA4 Event».
- Define the name of the event and the parameters you want to track (e.g. «click_button»).
- Configure activation conditions, such as a click on a specific button.
- Publish the changes in GTM.
Using gtag.js (Code on the site)
If you prefer to have full control over the code, you can use gtag.js to send events. The code would look like this:
gtag('event', 'event_name', {
parameter1: 'value1',
parameter2: 'value2'
});
This method is ideal if you have access to the source code of your website.
From the GA4 Interface
In some cases, you can create customized events directly in the «Events» of your GA4 property by modifying existing events. This approach is simpler but has limitations if you need more complex events.
3. View and Verify the Custom Event
Once you have submitted your customized event, it is important to verify that everything is working properly. It may take up to 48 hours for events to appear in the «Events» of GA4.
However, for immediate testing, use the function «DebugView» from GA4. This tool allows you to see in real time the events that are being sent to the platform, which will help you to confirm if the configuration is correct.
4. Create Custom Parameters, Dimensions and Metrics
If your events contain additional parameters, such as button_type o purchase_value, it is important to record these parameters as dimensions o custom metrics to analyze them in the reports.
To Create Custom Dimensions in GA4:
- Go to Administrator > Custom Definitions > Create Custom Dimensions.
- Complete the required fields:
- Name of dimension
- Scope (event or user)
- Description
- Event parameter (use the exact name you used in GTM or in the code)
Remember that, in standard accounts, you can create up to 50 dimensions and 50 custom metrics per property.
5. Cardinality and Boundary Considerations
It is important to keep in mind that if your custom parameter can have more than 500 different values (such as dynamic URLs or product categories), you will be dealing with a high cardinality dimension. This may cause some values to be grouped under the category “others”, which may affect the accuracy of your analysis.
Always check the limits of dimensions y custom metrics to ensure that the data is recorded correctly and usefully.
6. Query and Use Data in Reports
Once you have set up your custom dimensions and metrics, you can use the events in customized reports y explorations of GA4. In addition, custom events can be marked as conversions as they are defined as objectives in the «Conversions» GA4, which will allow you to more accurately measure your business KPIs.
7. Important Notes
- Custom events in GA4 are essential to obtain accurate data on user interactions, as the platform operates under a event-driven model.
- Only the customized events require this additional step of configuring parameters and metrics so that they can be properly analyzed in the reports.
- Don't forget to always use the DebugView of GA4 for immediate testing.
8. Conclusion
Measuring personalized events in GA4 is a crucial process for understanding your users' behavior and optimizing your marketing strategies. Although the technical implementation may seem challenging, the benefits you will gain from analyzing this data far outweigh the initial effort.
