Set Up dual tracking with Universal Analytics and GA4

Google Universal analytics are reaching end of life in July 2023! We have put a quick guide in place to set up dual tracking and transition to the new Google Analytics 4 in a fast and efficient way. Although dual tracking will allow you to retain data from the moment you have set up GA4 your historical data will be eventually not be accessible. The sooner you set up G4A the sooner you will preserve your data going forward!

The steps below assume that there is already a Google Analytics account set up and you are using Google Tag Manager to integrate Website Tracking on your website. There are 8 steps in total from creating the new property to testing that the set up has been completed. This process should be smooth and you shouldn’t encounter any obstacles. If there are any issues during the set up please contact Discover Digital at and our team will be in touch.

Top Level Steps

1.         Create the new Google Analytics 4 property

2.         Create a data stream for the new GA4 property

3.         Note the Measurement ID from the new data stream

4.         Create the GA4 Configuration Tag in Tag Manager

5.         Use the Measurement ID and set up tag firing for All Pages

6.         Preview the new tag using Google Tag Manager Preview Mode (the configuration is not live)

7.         Publish your new tag in Google Tag Manager (configuration is live)

8.         Test that configuration has been successful (traffic in the GA4 Profile)

Detailed Steps

Step 1: Create Property

Login to the GA account and enter the admin section. From this screen click on the “Create Property” button. Enter the name of the property e.g. “Test Website GA4”. On the reporting time-zone enter the time-zone that the business operates on e.g. United States and set the currency appropriately e.g. “USD”.  You do not need to set up the “Advanced Options”. Click the Next Button

Step 2: Create a data stream

Select the “Web” option. Enter the website url e.g. "". On the Stream name you can simply enter the Website Name e.g. Test Website. Make sure that the “Enhanced Measurement” is selected so all relevant interactions are tracked for the website. Click “Create Stream”.

Step 3: Measurement ID

After completing step 2 a “Measurement ID” code is created. There is a “copy” button next to it that needs to be clicked as the code is needed for Step 5.

Step 4:  Create the GA4 Tag in GTM

From your GTM account click on the New Tag. Name the new tag e.g.”GA4”. Click on the “Tag Configuration” and then on Choose a Tag type, the tag type to choose from the list provided is “Google Analytics GA4 Configuration”.

Step 5: Use the Measurement ID and set up tag firing for All Pages

During Step 3 you have created a measurement ID that has been copied. Now it the time to “paste it” on the Measurement ID field. Additionally make sure that you select the Send a page view event when this configuration loads. Then click Save. On the Choose a Trigger screen select the “All Pages” option.

Step 6:  Preview the new tag using Google Tag Manager Preview Mode

From the main workspace click the “Preview” Button. Enter the website that you would like to test e.g. the "" one and hit Connect. If all has been set up correctly you should see the new tag “GA4” alongside with the rest of your tags.

Step 7: Publish your new tag in Google Tag Manager

If your new tag is showing, you can exit this screen and hit the “Submit” button. The “Submit Changes” window will pop up. You can enter a version name for reference e.g. “GA4 Tag Creation”. Then click Publish.  Your set up is now complete!

Step 8: Testing

To make sure that all is in order you can visit your website to ensure there is traffic generated. Then check the new GA4 property that you have created and test that there is real-time traffic. This might not be instant so allow a short window for the data to populate. Well done for completing your set up!
