Cross-device tracking is the practice of tracking a user’s activity across multiple devices, such as a desktop computer, a smartphone, and a tablet.
This allows businesses to gain a more complete picture of a user’s behavior and interests, and to deliver more personalized and relevant content and advertising.
Cross-device tracking typically involves using cookies, device IDs, or other tracking technologies to identify users across devices and to link their activities.
This can provide valuable insights for businesses, but can also raise privacy concerns if users are not adequately informed and do not have the ability to opt out of tracking.
