Zero Party Data for Personalization

Zero-party data is information that customers willingly share with a business, such as preferences, interests, or feedback. Examples include survey answers, quiz results, or account settings. This type of data is highly reliable because it comes directly from the user.

Zero-party data is increasingly important as third-party cookies phase out and personalization takes center.
For example, if a customer states they prefer eco-friendly products, brands can prioritize showing those items, strengthening personalization and loyalty.

Brands typically gather this kind of data through preference centers, interactive content, or loyalty programs. The advantage is accuracy and compliance, but the challenge is motivating users to provide it.
