First-Party Data

Data collected directly from your own customers.

First-Party Data is information you collect through your own channels: purchases, site browsing, emails, forms. Unlike Third-Party Data (third-party cookies that are being phased out), it's reliable, GDPR-compliant, and sustainable. In e-commerce, leveraging your First-Party Data to segment and target advertising audiences has become a major competitive advantage.
