GA4 Auto-migration: Why and how to opt-out
If you haven’t migrated to Google Analytics 4 (GA4) by now, you’re likely flooded with reminders from Google to get to it! But what does auto-migration mean? And can it break your Shopify data? With Universal Analytics’ July deprecation date coming soon, the pressure is on. To encourage UA users to make the switch, Google began auto-migrating UA properties to GA4 on March 1, 2023. While this may sound helpful, you actually do not want to rely on Google’s auto-migration to GA4. For data-driven ecommerce brands, Google’s “basic” configurations aren’t going to cut it, and Google’s auto-migration could actually hinder your data quality. The same goes for Shopify’s Google sales channel. With a few simple steps, you can opt out of GA4 auto-migration and set up your GA4 property correctly. There’s a lot of confusion in the marketplace right now, especially when it comes to tracking ecommerce stores in GA4. Whether you’re on Shopify, BigCommerce, or another ecommerce platform, it’s a must to track checkout steps and conversions, but auto migrations don’t cover that at all. So in this post, we’ll be clearing up: Why you should opt out of auto-migration (and how to do it) How to ensure data quality in GA4 How to track ecommerce events in GA4 Why you need to opt-out It’s important to note that GA4 is a completely new reporting tool, built from the ground up for faster reporting, increased flexibility, and streamlined audience building. GA4 relies on a new data model — event-based tracking, rather than session-based tracking — and doesn’t track data like-for-like with UA. To avoid any data disruptions and ensure data integrity, brands need to manually set up their GA4 properties.

If you’ve already set up a GA4 property, you may think this doesn’t apply to you, but even if you have manually created a GA4 property, it’s crucial that you switch off the auto-migration toggle to avoid further issues. Duplicated orders We’ve seen Shopify stores face duplicated orders and inaccurate data after missing this key step. Even with the proper data tech stack, brands are struggling with data quality issues because they have not opted out of auto-migration. Event naming If you’ve auto-migrated your UA events into GA4, your event naming can majorly skew conversion tracking, if not done properly. GA4 limits event names to 40 characters or less, so any UA events automatically migrated to GA4 that are 40+ characters will not be reported as a conversion because the appended “_c” will be missing. Managing users With great power comes great responsibility. There may be users you don’t want to migrate to GA4 so it’s best to review account and property users and the access they’re granted during migration. How to opt out of GA4 auto-migration It’s easy to opt out of auto-migration. Simply access the GA4 Setup Assistant via the Admin panel and scroll down to ‘Automatically set up a basic Google Analytics 4 property’ and ensure that the toggle is switched off, as pictured below. As an added measure, ensure that you have “Collect Universal Analytics events” toggled off in your data stream’s tag settings, as shown below.

How to track ecommerce events in GA4 Shopify’s GA4 integration is now available through the Google Sales Channel App, but as with Shopify’s native integration with UA, it comes with a few core limitations. Beyond this app, you have two other options: Google Tag Manager (GTM) GTM is a common tracking solution for ecommerce stores. And while GTM itself is free to use, it comes with a price — GTM is very time-consuming, complex, and often costly to maintain, especially for a lean team. Plus, Shopify’s recent updates removed the ability to add scripts to checkout.liquid, no longer permitting brands to track the checkout funnel with GTM.
