The objective of the Identity resolution graph is to identify all the individual sources of information spread across numerous data sources in ZI as well as data gaps that need to be filled to create one of the most powerful B2B Identity Graphs.

For MarketingOS, having a robust identity graph would make our Advertising, Websights and Intent products more sticky and valuable to our customers, and opens up opportunities in the realm of personalization and monetization. A full range of identifiers associated with both devices and people will be inventoried and considered for inclusion in the identity resolution service for both visitor identification and ad use cases. From an Advertising perspective, Identity graph will be used to identify (and map all the identities) and activate marketing activities on different platforms (display, social, email, platforms, etc), reporting and take attribution across website engagement (Websights) activities, to CRM conversion(closed /won deals)
