Implement the GA4 Tracking Code

Once your GA4 property is set up, you need to implement the GA4 tracking code on your website. This code is different from the traditional Universal Analytics tracking code, so it is essential to update your website accordingly. The new tracking code uses a global site tag (gtag.js) that collects and sends data to both GA4 and Universal Analytics properties simultaneously.

To implement the GA4 tracking code, follow these steps:

  • Access the GA4 property you created in your Google Analytics account.
  • Navigate to the Admin section of your GA4 property.
  • In the Property column, click on “Data Streams” and select the appropriate data stream for your website or app.
  • From the data stream settings, locate the Measurement ID, which is a unique identifier for your GA4 property.
  • Copy the Measurement ID as you will need it to configure the GA4 tracking code.

Next, update your website code to include the GA4 tracking code:

  • Locate the global site tag (gtag.js) code snippet provided by Google in your GA4 property settings.
  • Insert the GA4 tracking code snippet in the header section of your website’s HTML or any other location recommended by Google.
  • Replace the placeholder value in the snippet with the Measurement ID you copied earlier.

Ensure that the GA4 tracking code is implemented on all the pages of your website or app where you want to collect data. This ensures comprehensive data collection across your digital properties.

Once the GA4 tracking code is implemented, verify its functionality by checking the real-time data in both GA4 and UA. You should see data being collected on both platforms simultaneously, indicating that the implementation is successful.

It’s important to note that during the transition period, when both UA and GA4 tracking codes are present on your website, it’s essential to ensure that the data collected is consistent and doesn’t result in duplicate tracking. You can prevent duplicate data by disabling duplicate pageview tracking in GA4 or implementing a filtering mechanism to exclude one of the tracking codes from specific pages.

By updating your website with the GA4 tracking code, you are paving the way for a seamless transition to GA4 while maintaining data collection on both platforms. This allows for data comparison, analysis, and a gradual shift towards leveraging the advanced features and capabilities offered by GA4.

Set Up Custom Events and Parameters

GA4 introduces a more flexible and customizable event tracking system compared to Universal Analytics. To take full advantage of GA4’s capabilities, you should set up custom events and parameters tailored to your specific business goals. Define events that align with key user interactions, such as button clicks, form submissions, or video views. Custom parameters enable you to capture additional data associated with these events, providing deeper insights into user behavior.

Dual tagging, which involves implementing both the UA and GA4 tracking codes on your website or app, enables you to capture data on both platforms. During this dual tagging phase, UA continues to function as your primary event tracking mechanism, while GA4 starts accumulating data for future analysis.

Mapping your UA custom events to GA4 involves creating equivalent custom events in GA4 that align with your existing UA implementation. This ensures that your event tracking remains consistent across both platforms and facilitates a seamless transition.

Start by identifying the custom events you have set up in UA and replicate them in GA4. Carefully consider the naming conventions and parameters used in UA, as they should be mirrored accurately in GA4 to maintain data integrity. Once you have created the corresponding events in GA4, update your tracking code to send these events to both UA and GA4 properties simultaneously.

During the dual tagging period, closely monitor and compare the data collected in UA and GA4. This allows you to ensure data consistency and verify that the mapped events are capturing the desired information accurately. It’s advisable to conduct thorough testing and validation to confirm that the mapped events are functioning as expected in GA4.

By mapping your UA custom events to GA4, you can gradually transition your event tracking to the new platform while preserving your historical record. This approach allows you to leverage the advanced capabilities of GA4 while still relying on UA until you are ready to fully switch over.
