1st party, 2nd party, and 3rd party data refer to the origin of data sets used in the digital advertising and marketing ecosystem.
1st Party Data: This type of data is collected by the individual organization or brand (“1st party”) and is typically collected from their customers, clients, or visitors. This information typically includes demographics such as age, gender, and location, but can also extend to more precise metrics like purchase history or web-browsing behavior.
2nd Party Data: This type of data is collected by another organization and shared "directly" with the company. The company that shares the data cannot use it itself and must pass it on to another company. This type of data usually originates from a corporation’s partners, clients, or affiliates.
3rd Party Data: This type of data is collected by analytics providers and other data brokers from multiple sources and then aggregated into a single dataset. This dataset typically includes web-browsing behavior and demographic data, allowing companies to find new, targeted audiences for their marketing efforts.
Using these data sources, marketers can create personalized experiences for their customers and acquire valuable insights on their prospects.
