If you get Google’s Analytics emails, you may have already gotten the word. But ICYMI, Google has once again reminded us that Universal Analytics (UA) will stop processing data on July 1.

What’s new is the email states that starting in March, any customer who does not set up a GA4 property with basic settings, Google will configure one with a few basic settings consistent with the existing Universal Analytics property; this includes certain conversion events, Google Ads links, and existing gtag or analytics.js tags.

Opt-out. If you don’t want Google automatically creating GA4 properties for you, you may opt-out via the instructions in this link.

Here is what the email says.

Subject: We’ll soon configure Google Analytics 4 for you

Hello.

Universal Analytics standard properties will stop processing data on July 1, 2023. To maximize historical data and to ensure that Google Analytics 4 (GA4) meets your specific needs, we recommend you make the switch to Google Analytics 4 now. This will give you the opportunity to customize the setup including using the latest site tag.

For any customer who does not set up a GA4 property with basic settings, starting in March, we will configure one with a few basic settings consistent with the existing Universal Analytics property; this includes certain conversion events, Google Ads links, and existing website tags.

For Universal Analytics customers whose websites are tagged with gtag.js or analytics.js (including through tag management systems like Google Tag Manager), we will create a connected site tag that will reuse existing tags when possible to send traffic to the new GA4 property. If you do not wish to have a GA4 property created and configured based on your Universal Analytics property and existing tags, you may opt-out.

Their ‘Learn More’ CTA directs to a Google Doc page that I don’t have access to.

The notification also appears in a yellow bar at the top of some Analytics accounts. Shameem Adhikarath noticed it last night and posted it to Twitter.

Why we care. With the discontinuation of Universal Analytics standard properties on July 1, 2023, advertisers need to switch to Google Analytics 4 to maximize historical data and take advantage of the latest analytics capabilities. If they don’t, Google may create a GA4 property for them with basic settings, which may not meet their specific needs. Therefore, to ensure accurate tracking and analysis of their advertising efforts, advertisers should make the switch to Google Analytics 4 now and customize the setup as needed.
