Zero-party data is information that a shopper voluntarily shares with a brand
Zero-party data is a term coined by Forrester Research that refers to data that customers intentionally and proactively share with a company. It is data that the customer voluntarily provides, often in exchange for a more personalized experience or tailored services. This can include preferences, purchase intentions, personal context, and how the individual wants to be recognized by the brand.
This kind of data is not only highly valuable for ecommerce brands as it is information coming right from the source, but its collection has become signifcantly more important as third-party cookies are phased out.
