First-Party Data
First-party data is information a business collects directly from its own customers, from orders and behavior to reviews and surveys.
What first-party data is
First-party data is information a business collects directly from its own customers and visitors: orders, on-site behavior, email signups, survey answers, reviews.
It contrasts with third-party data, bought from outside brokers and built from tracking across other people’s sites.
Why first-party data matters
Third-party tracking keeps shrinking as browsers and regulators clamp down. What a store learns directly from its own customers stays usable, accurate, and consented.
It’s also better data: actual purchases and stated preferences beat inferred interest from elsewhere.
First-party data stores already have
- Order history and product preferences
- On-site behavior: views, carts, searches
- Email and SMS engagement
- Reviews, ratings, and survey responses
Frequently asked questions
What’s zero-party data then?
Information customers volunteer on purpose: quiz answers, preferences, review text. It’s a subset marketers name separately because the customer chose to share it.
How do stores use first-party data well?
Personalized recommendations, lifecycle emails, and smarter merchandising, all with plain-language consent and an easy way for customers to see and change what’s held.
