Zero-Party Data
Information a customer deliberately shares with a business (a stated preference, a quiz answer), as opposed to data inferred from behavior.
In practice
It's considered more reliable and privacy-friendly than data inferred from browsing behavior, since the customer chose to share it directly - though it requires giving them a genuine reason to do so, like a personalized recommendation in return.
A skincare brand's onboarding quiz asks about skin type and concerns, then uses those direct answers to recommend products - rather than guessing from browsing history.
Why it matters
As third-party cookie tracking becomes less reliable and more restricted, zero-party data - collected with explicit participation - is becoming one of the most durable ways to personalize marketing.
Worth knowing
- Collected through direct methods like quizzes, preference centers, and surveys.
- Generally viewed more favorably by privacy regulations than data inferred from tracking.
- Requires giving the customer a clear, immediate benefit in exchange for sharing it.
