Explain the relationship between DMP and CDP in media planning.

• A. DMP collects anonymous data for targeting; CDP consolidates known customer data with PII to create unified profiles; CDPs are persistent and privacy-focused.
• B. DMP stores customer emails; CDP only stores ad impressions.
• C. DMP and CDP are the same.
• D. DMP is for offline data; CDP is for social data.

Answer: (A)

In media planning, the distinction hinges on identity and data type. DMPs are built to collect anonymous data—cookie and device identifiers from various sources—to form audience segments used for targeting in programmatic ad buys. The data in a DMP is non-identifiable and typically not tied to a specific person, with retention and use geared toward real-time activation across campaigns.

CDPs, on the other hand, bring together known customer data, including PII from CRM, offline records, websites, and apps, to create unified profiles that persist across time and across channels. This means a single customer view that can be activated for personalized experiences, across devices and touchpoints, while supporting privacy controls and consent governance.

So the best description is that DMPs handle anonymous data for targeting, while CDPs consolidate known data with PII to build persistent, privacy-conscious profiles. In practice they complement each other: CDPs feed first-party data into broader marketing activation, and DMPs handle anonymous audience targeting at scale in ad ecosystems.
