What is Third-Party Data?
Third-party data in ad networks refers to user information collected and aggregated by external organizations, rather than the advertiser or publisher directly. This data is sourced from various websites and platforms, then sold or shared through data marketplaces. It includes insights like interests, online behavior, purchase intent, and demographic profiles.
Ad networks use third-party data to enrich audience segments, enabling more precise targeting and personalized ad delivery. Unlike first-party data, which is gathered directly from users through owned channels (e.g., website analytics), third-party data provides broader audience reach and deeper behavioral insights.
