What Is a Customer Data Platform (CDP)?
A CDP, or Customer Data Platform, is software that collects and organizes customer data from various sources (first-party data) into one place (a Single Customer View) so marketers can put it to use.
How is a CDP different from a CRM?
- CRM: Focuses on storing sales data and communications (interactions)
- CDP: Focuses on storing behavioral data from every touchpoint, including the web, apps, and physical stores
Why do businesses need a CDP?
- Unified Profile: See a complete picture of each individual customer, no matter which channel they came in through
- Real-time Personalization: Serve ads or send emails to customers immediately based on their latest behavior
- Cross-channel Marketing: Create a seamless experience wherever the customer is
Having a CDP helps a business move from "guessing what customers want" to "understanding customers from real data."
