In October 2021, Google announced that it would be moving away from Google Analytics Universal to the new and improved Google Analytics 4.

For digital marketers, this means that the way we collect and analyze data will need to change. This guide will show you the GA4 best practices: everything you need to know about Google Analytics 4, including how to set it up, how to use it, and what best practices you should follow for using it effectively.

If you want to make sure you’re using the latest version of Google Analytics to its full potential, then this guide is for you. Let’s get started!

What is Google Analytics 4 (GA4)

Google Analytics 4 (GA4) is the latest version of Google Analytics. It’s a complete re-imagining of how analytics works, and it’s designed to help digital marketers make a smooth transition from the old Google Analytics (Universal Analytics) to the new GA4.

How does tracking work on GA4?

Google Analytics 4 uses a combination of event-based data and parameters to track user engagement. The events are then used to populate user properties, which in turn help define audiences for remarketing purposes. This approach gives you a more complete understanding of how users interact with your site or app.

Event tracking on Google Analytics 4

Event tracking on GA4 is setup differently than on Universal Analytics. Instead of setting up individual events, you’ll need to define a set of parameters that will be used to track all the events you want to monitor. The parameters can be customized according to the needs of your business.

Here’s a step-by-step guide on how to do event tracking on GA4:

1) Log into your Google Analytics account and select the Admin tab.

2) Under the Events heading, click Parameters.

3) Click +New Parameter.

4) Enter a name for the Parameter and choose what type of data you want to collect.

5) Save the changes.

6) Follow the same steps to create additional parameters as needed.

7) Add the parameters to your events in Google Tag Manager.

8) Publish the changes.

eCommerce tracking on Google Analytics 4

Google Analytics 4 has a built-in eCommerce tracking feature that can be used to track sales and conversion data. This feature is not available on Universal Analytics.

To set up eCommerce tracking on GA4, follow these steps:

1) Log into your Google Analytics account and select the Admin tab.

2) Click Admin, and navigate to the view you want. 

3) In the VIEW column, click Ecommerce Settings. 

4) Set Enable Ecommerce to ON.

5) Under the Events heading, click Ecommerce.

6) Select/create an eCommerce-specific event from the drop-down menu.

7) Follow the same steps to create additional parameters as needed.

8) Add the parameters to your events in Google Tag Manager.

9) Publish the changes.

User properties on GA4

Another important difference between Universal Analytics and Google Analytics 4 is how user properties are handled. On Universal Analytics, user properties are set at the individual session level. This means that they can’t be used to track long-term engagement or create remarketing audiences.

GA4 uses a different approach called “user-scoped” properties. These properties are associated with a specific user ID and can be used to track engagement over time. They can also be used to create remarketing audiences.

What’s different about GA4?

The main difference between GA4 and Universal Analytics is the way in which data is collected and processed. Universal Analytics relies on cookies to track user behavior, while Google Analytics 4 uses first-party data that’s stored in the browser’s Local Storage. This makes it possible to track users across devices and platforms without the need for cookies.

Another key difference is the way in which GA4 processes data. Universal Analytics uses a batch processing system, which means that data is processed in batches at predetermined intervals. Google Analytics4 uses a stream processing system, which means that data is processed in real-time as it’s received.

Finally, GA4 includes a number of features that are not available on Universal Analytics. These include:

1. Event-based data collection: Google Analytics 4 collects data based on events, which gives you a more complete picture of how users interact with your site or app.
2. User-scoped properties: GA4 uses user-scoped properties to track engagement over time and create remarketing audiences.
3. Built-in eCommerce tracking: Google Analytics 4 has a built-in eCommerce tracking feature that can be used to track sales and conversion data.
4. Cross-device tracking: GA4 can track users across devices and platforms without the need for cookies.
5. Custom analysis: Google Analytics 4 includes a number of features that make it easy to perform custom analysis. These include custom reports, segments, and dimensions.

Key changes to Google Analytics 4

There are several key changes that users need to be aware of when migrating to GA4. These include:

• A new data model that is event-based
• The ability to collect data offline and then upload it later
• Improved cross-platform measurement
• Greater control over the collection of user data

These changes mean that there will be a different way of understanding and working with data in GA4. However, the end goal is still the same – to help you make better decisions about your marketing efforts.

How to update to Google Analytics 4 (GA4)

Now that you know what’s changing, it’s time to update your Universal Analytics tracking code snippet to the new GA4 code. You can find your Google Analytics 4 code in the Admin section of your Google Analytics account.

Making the switch to Google Analytics 4 (GA4) from Universal Analytics doesn’t have to be complicated. In fact, it’s a pretty straightforward process. Here’s a step-by-step guide to help you make the transition:

1) Log in to your Google Analytics account and navigate to the Admin section.

2) In the Property column, click GA4 Setup Assistant, it is the first option in the Property column, and create a new Google Analytic 4 property.

3) Under Global Site Tag (gtag.js), click Send traffic to GA4 property only.

4) Copy the tracking code snippet that appears under this setting.

5) Paste this tracking code into your website’s header or tag manager template, replacing your existing Universal Analytics snippet.

6) That’s it! Your data will now be migrated over to GA4 and you can start using all of the new features and benefits that come with it.
