First-party data is information collected directly from customers and prospects through their interactions with your website, app, email, forms, and customer data platform (CDP). It includes behavior data (page visits, downloads, clicks), declared data (form submissions, survey responses), and transaction data (purchases, contract details). First-party data is owned and controlled by your company.
First-party data is becoming essential as third-party cookies deprecate and privacy regulations tighten. While you can no longer reliably track prospects across the web with cookies, first-party data captures their engagement with your owned properties, enabling personalization without reliance on external data sources.
For ABM, first-party data powers account engagement scoring, personalization, and nurturing. You know which accounts visited your site, which pages they viewed, which content they downloaded, and which features they explored. This zero-party knowledge enables precise targeting and messaging without external intent data purchases.
First-party data also builds customer trust. Customers know their data is yours to protect, not sold or shared broadly. This transparency strengthens relationships and improves brand perception compared to companies relying on purchased data.
Zero-party data is information customers voluntarily submit (surveys, preference centers); first-party data includes all customer-shared information collected via interactions and transactions.
