Google has streamlined the process for using imported user data to build audiences in Google Analytics 4 (GA4).
This eliminates the need for users to visit a website or app before joining designated audiences.
Google’s official announcement states:
“We’ve made it easier to use imported user data with audiences. Now, data you upload, joined via either user ID or client ID can be used to qualify users for your GA4 audiences right away, without them needing to visit your site or app first.”
