Dynamic remarketing in Google Ads has become easier to set up. Google Ads now supports using ecommerce data directly from Google Analytics to power personalized product ads, without requiring dynamic remarketing events to be implemented through the Google Ads tag.
In practice, this means advertisers can launch dynamic remarketing campaigns using existing Google Analytics ecommerce tracking, as long as a few conditions are met. Ecommerce tracking in Google Analytics must be accurate, product IDs need to match the product feed used in Google Merchant Center, and Personalized Advertising must be enabled. When these requirements are in place, Google Ads can use GA data to identify viewed products and serve relevant ads automatically.
This update lowers the technical barrier for advertisers who already rely heavily on Google Analytics and want a faster or simpler way to activate dynamic remarketing. For smaller teams or businesses with limited development resources, this can significantly reduce setup time.
Important performance considerations
While this GA-based setup is convenient, it comes with trade-offs. Remarketing based on the Google Ads tag still processes data faster and typically captures a larger share of users. This is because the Ads tag is designed specifically for remarketing use cases and does not depend on Analytics data processing timelines.
As a result, advertisers using GA-only dynamic remarketing may experience:
- Slight delays in audience population
- Smaller remarketing lists compared to Ads tag-based setups
- Less flexibility in advanced remarketing configurations
What this means for advertisers
For advertisers looking for speed and simplicity, GA-based dynamic remarketing can be a practical starting point. It works well when ecommerce tracking is clean and when time-to-launch is a priority.
However, for advertisers focused on maximum scale, faster audience updates, and optimal performance, the Google Ads remarketing tag remains the preferred solution. Many mature accounts may even use GA-based remarketing as a temporary or complementary setup, while relying on the Ads tag for core performance.
What you should do
Review your current ecommerce tracking quality in Google Analytics. Confirm product ID consistency with your feed and ensure Personalized Advertising is enabled. If performance is critical, plan to implement or maintain the Google Ads remarketing tag alongside GA-based tracking.
This update, shared by Dario Zannoni, offers more flexibility, but not a full replacement for tag-based dynamic remarketing.
