First-Party Data
Data you collect directly from your audience, like email addresses, survey responses, and on-site behavior.
First-party data is information you collect directly from your audience through interactions on your own properties — newsletter signups, account registrations, survey responses, purchase history, and on-site behavior. Unlike third-party data (collected by external companies via cookies), first-party data is yours to own and use.
As third-party cookies phase out, first-party data becomes increasingly valuable for ad targeting. Publishers who collect first-party data can offer advertisers audience segments based on declared interests and behaviors, commanding premium CPMs. Building a first-party data strategy starts with providing value exchanges (newsletters, gated content, interactive tools) that encourage users to share their information willingly.
