What is First-Party Data?
Data collected directly from your audience on your owned properties
Quick Definition
First-party data is information collected directly from your audience on properties you own—your website, app, CRM, and other owned channels. It's the most valuable and reliable data you have.
In an era of privacy regulations and cookie deprecation, first-party data has become the most valuable asset for marketers and sales teams. Unlike third-party data that's aggregated from external sources, first-party data comes directly from interactions with your brand on properties you control. It's more accurate, compliant, and actionable because it reflects direct engagement with your business.
