Customer Data Platform (CDP)
A customer data platform (CDP) is a system that unifies a company's first-party customer data into persistent, individual profiles that marketing and advertising systems can use.
Key takeaways
- A CDP unifies first-party data into a single, persistent customer profile.
- Unlike a DMP, it centers on known individuals, not anonymous segments.
- It has grown more important as third-party identifiers disappear.
- CDPs feed activation across advertising, CRM, email, and personalization.
First-party at the center
A CDP ingests data a company owns "” purchases, app activity, CRM records, loyalty "” resolves it to individuals, and maintains an always-on profile rather than a rented segment. That owned foundation is why CDPs weathered cookie deprecation far better than DMPs.
Activation and clean rooms
CDPs push audiences to DSPs, walled gardens, and personalization engines, and increasingly interoperate with data clean rooms, where a brand's first-party data can be matched against a publisher's without either side exposing raw records.
