What is Cross-device tracking?

Cross-device tracking is a method used to track user behavior across multiple devices. Essentially, it allows advertisers and marketers to follow user activity as they switch between their smartphone, tablet, laptop or desktop computer.

This type of tracking is becoming increasingly popular as today's consumers use multiple devices throughout the day. But how does it work? When a user logs into an app or website on one device, that information is stored in a database. The next time the user logs in on a different device, the database recognizes them and can connect the dots between their actions on both devices.

While some users may find this intrusive, others appreciate the convenience of having personalized recommendations and targeted ads across all of their devices.
