What feature in Google Analytics allows you to connect individual customers' behavior across different platforms and devices?

The User-ID feature in Google Analytics is designed specifically to track individual users across different devices and platforms, allowing for a more comprehensive view of user interactions. By implementing User-ID, you can assign a unique identifier to each user who logs into your application or website. This identifier persists regardless of the device used, enabling the analysis of user behavior as they switch between devices, such as mobile phones, tablets, and desktops.

This functionality enhances the accuracy of tracking user journeys and provides deeper insights into user engagement and behavior. It allows businesses to measure and understand how users interact with their content and products across multiple platforms, which is crucial for effectively targeting and personalizing user experiences.

Other options like event tracking, segmentation tools, and cross-device user tracking do provide useful analytics insights, but they do not specifically focus on linking individual user behavior across multiple devices the way User-ID does. Event tracking captures specific interactions, segmentation tools categorize users based on distinct characteristics or behaviors, and cross-device user tracking is a broader concept that may not tie directly into individual user identification like User-ID does.
