What is First-party Data? Definition for Analytics and Privacy
First-party data is data collected directly from your own audience, website, app, product, or customers. It can include analytics events, account data, purchases, form submissions, email engagement, support interactions, and product usage.
First-party data is valuable because it comes from your direct relationship with users rather than from external brokers or cross-site advertising networks.
First-party data examples
Examples include:
- Website visits
- Product events
- Purchases
- Signup data
- Customer preferences
- Email subscriptions
- Support tickets
- Survey responses
- Feature usage
- Revenue data
Some first-party data can still be personal data, so privacy and consent requirements still matter.
First-party vs third-party data
First-party data is collected by your own business from your own audience. Third-party data is collected by external companies and often used for advertising, profiling, or enrichment.
As browsers restrict third-party cookies and privacy expectations rise, first-party data has become more important for trustworthy measurement.
