This document discusses user segmentation and how data from digital platforms can be used to better target customers. It notes that horizontal segmentation, which uses one message for all, is less effective than customizing messages for different customer segments identified through data analysis. The document provides several statistics that illustrate the growth of mobile usage and how people use mobile devices for tasks like searching and making purchases locally. It also gives examples of how Google and Facebook segment users and target them with customized information and ads based on their individual data profiles and activities online.
