你可以使用這項 Analytics 功能將自己的 ID 與個別顧客建立關聯，針對顧客在不同平台和裝置上的各種互動連結他們的行為。

User-ID allows you to associate your own identifiers with individual customers, linking their behavior across different platforms and devices. This provides a more holistic view of the customer journey, as it unifies data from various touchpoints. Predictive audiences use machine learning to identify future customer behavior, but don't directly link individual IDs. Device ID refers to an identifier specific to a device, not a cross-platform customer identifier. Audience triggers are conditions that, when met, cause an audience to be created or updated, but they don't perform the core function of linking individual customer IDs across platforms.
