Identity resolution: what it is and how it works

Identity resolution is a complex process that links fragmented customer interactions across various touchpoints and systems to create a unified customer profile, enabling businesses to deliver personalized experiences and improve marketing effectiveness. As customers engage with businesses through multiple channels such as mobile apps, websites, and in-store purchases, identity resolution collects and matches identifiers like email addresses, device IDs, and cookies to build a comprehensive view of customer behavior. This approach helps businesses understand anonymous website visitors, ensure consistent experiences across devices, and enhance marketing strategies by accurately targeting audience segments and avoiding duplicate profiles. The process involves deterministic matching, which relies on verified identifiers for high accuracy, and requires a centralized source of customer data to maintain data quality. By integrating real-time data with historical records, identity resolution allows organizations to enrich customer insights and craft more targeted marketing campaigns, ultimately transforming fragmented data into actionable intelligence.
