What is First, Second, and Third-party data?

First-party data is data that is collected by a company about its own customers and business operations. This data is typically collected through first-party systems such as web analytics, customer relationship management (CRM), and point-of-sale (POS) systems.

Second-party data is data that is collected by one company about the customers of another company. This data is typically collected through second-party relationships, such as data exchange partnerships, co-marketing arrangements, and data licensing agreements.

Third-party data is data that is collected by a company about people who are not its customers and who are not associated with its business operations. This data is typically collected through third-party data providers, such as data aggregators and data brokers.
