What is Third-Party Data?
Third-Party Data is Data purchased or obtained from external providers who collected it from other sources.
Definition
Third-party data is information collected by someone else and sold or shared with you. Contact databases, firmographic data, intent signals, and demographic profiles are common examples. The data wasn't collected through your direct relationship with the individual. Quality and compliance vary widely by provider.
Why It Matters
Third-party data fills gaps in your first-party data. You can't know what technology a prospect uses or what topics they're researching without external signals. But third-party data is under pressure from privacy regulations and the deprecation of third-party cookies.
Example
A sales team buys a list of contacts from ZoomInfo to fuel outbound prospecting. The data includes emails, phone numbers, and firmographics that the company didn't collect directly.
