Enhancement in User Data Import for Google Analytics 4 Audiences

Google has improved the functionality of user data import in Google Analytics 4 audiences. Data imported via user data import, linked by either user ID or client ID, is now readily available as criteria for user qualification in existing GA4 audiences, without requiring additional user interaction. This means that any users imported into Analytics who meet the criteria for an existing GA4 audience are automatically added.

For example, suppose a user creates a “Gold” loyalty tier audience based on a user-scoped custom dimension indicating the user’s loyalty tier. When loyalty tier data is uploaded via user data import, users classified as “Gold” tier are automatically integrated into the GA4 audience. There is no need to wait for their activity on the website or app before qualifying.
