6 Identity resolution and enrichment: Building a complete customer profile

Before identity resolution can happen, one has to ensure that accurate data from first-party data sources—apps, websites, or smart devices—is collected and made available where the identity resolution algorithm runs. The process is non-trivial and requires a deep understanding of the customer journey.

First-party data can come from many different sources, often creating a fragmented view of each customer by data source. We covered the marketing data architecture in chapter 5, so now let’s dive deeper into how we can harmonize those fragmented data sources into a single customer profile.
