Question: Which Google Analytics feature lets you associate your own identifiers with your individual customers so you can connect their behavior across different interactions on various devices and platforms?
- Predictive audiences
- Audience triggers
- Device ID
- User-ID
Explanation
User-ID lets Google Analytics associate identifiers generated by a business with individual users. This helps connect behavior across different sessions, devices, and platforms when users can be consistently identified. Analytics uses each provided user ID as a separate user for more accurate cross-platform measurement. The identifier must be created and assigned by the business, typically when a user signs in.
Why the other options are incorrect
Device ID is incorrect because it identifies a device or browser instance, not a business-defined customer identifier.
Predictive audiences is incorrect because they group users based on predictive metrics, not assigned customer identifiers.
Audience triggers is incorrect because they create events when audience conditions are met, not connect users across devices.
