What Is First-Party Data Targeting & Why Does It Matter for CTV?
First-party data targeting uses owned customer lists, CRM databases, and behavioral signals from direct transactions to precisely reach high-value audiences on Connected TV (CTV). It matters for CTV because third-party cookies are deprecating, making first-party data essential by 2026, unlike traditional TV’s demographic guessing or fragmented programmatic display.
First-party data includes purchase history, email interactions, and website behaviors collected directly from customers. With privacy regulations tightening, brands rely on this data for compliant, accurate targeting. CTV’s household-level precision amplifies its power, contrasting broad TV reach. As CTV reaches millions of viewers, precision targeting differentiates winners.
“The cookie deprecation accelerates the shift to first-party data, creating urgency for CTV marketers. Platforms like Starti enable seamless CRM uploads for lookalike modeling, delivering 95%+ accuracy that traditional methods can’t match. This isn’t just compliance—it’s a competitive moat for 3–5x ROAS in a cookieless world.”
