Create segments in Google Analytics 4

Note

This is a third-party integration and is not an Optimizely subprocessor. See Optimizely's Third-Party Add-Ons & Platform Integration Terms.

You must integrate Optimizely Web Experimentation with Google Analytics 4 (GA4) to create segments for Web Experimentation within GA4.

If you use the GA4 Report Generation feature, you do not need to create segments manually. Instead, you can use the Audiences created automatically with the GA4 integration.
