Audience Acuity
Audience Acuity
Identity resolution is the process of matching identifiers across all devices and touchpoints to a single, unified, persistent profile. In our highly digitized world, the inability to identify and contextually interact with consumers across channels is a top issue facing organizations. Today, the vast majority of online visitors do not log in, purchase, or authenticate themselves creating lost opportunities with an engaged consumer. The goal is to develop a holistic view of the customer, the digital identifiers they use, and their interactions with the brand, into an opportunity for exceptional customer experience. This becomes even more urgent as marketers prepare for the planned deprecation of the third-party cookie. We developed a unique and highly authoritative identity graph that is purely deterministic and at scale. The aim of our work is to enable firms to identify and contextually interact with audiences across channels and devices at scale.
