By popular demand, Google Analytics 4 is up and running for Site Builder!
Sign up and Create a Google Analytics 4 Account, and then Create a GA4 Property for your site.
Once you have a Google Analytics 4 property number, you can go to your Site Builder site, and add the GA4 Property under the Site Information and Appearance section, toward the bottom of the page.
You can continue using your original Universal Analytics Property until Google shuts it down later this year. Your older UA Property will have historical data that GA4 will not have. If this data is important it's possible, though not convenient to back up the old data.
Test the Google Analytics 4 setup
You can test GA4 to make sure it's working by looking at Real Time User Activity under Reports. Real cumulative data will most likely take several days.
Tip: Access your site from several browsers and devices and you'll see activity!
