A conversion / cross-device transaction refers to the process of a consumer completing a purchase or taking a desired action on a website or app using multiple devices. This can include starting the transaction on one device, such as a laptop, and completing it on another, such as a smartphone. It also encompasses the tracking and attribution of these actions across devices, allowing businesses to gain a more comprehensive understanding of their customers’ behavior and preferences. With the rise of mobile and multi-device usage, conversion / cross-device transactions have become an essential aspect of e-commerce and digital marketing strategies.
