What are the differences between zero-, first-, second- and third-party data?

Zero-party, first-party, second-party, and third-party data are different types of data that businesses can collect and use for various purposes. Here’s a breakdown of the differences between these types of data:


  1. Zero-party data: This type of data is voluntarily shared by the customer, often through surveys, polls, or direct interactions with the brand. It is the most transparent and relevant type of data, as it comes directly from the customer and is used to improve their experiences. Examples of zero-party data include preferences, interests, and feedback provided by the customer.
  2. First-party data: First-party data is collected by the brand or organization directly from its customers. It includes data from website and software interactions, purchase history, contact information, and more. First-party data is valuable for understanding customer behavior and preferences, and it helps build a direct relationship between the brand and the customer.
  3. Second-party data: Second-party data is essentially first-party data that comes from another organization outside your own. This can be obtained through a trusted partnership or by purchasing the data from a reliable source. Second-party data can include customer surveys, feedback, website and mobile app interactions, purchase history, and contact information.
  4. Third-party data: Third-party data is data that is bought from an outside source that is not the original collector of the data. It can come from a wide variety of sources, both offline and across the digital ecosystem. Third-party data is often aggregated, segmented, and sold to marketers for their own advertising campaigns. It provides additional demographic details, behavioral context, and transaction insights, helping marketers improve their understanding of customers and add multidimensional insights.


The main differences between these types of data lie in how they are obtained and their level of transparency and relevance. Zero-party and first-party data are more transparent and relevant, as they come directly from the customer and are used to improve their experiences. Second-party and third-party data, on the other hand, are obtained from external sources and may not be as reliable or accurate, as their origins and collection methods are often unknown.
