Why Are Third-Party Cookies Disappearing From CTV Advertising?
Safari and Firefox have fully phased out third-party cookies, with Chrome’s deprecation set for 2025 amid escalating GDPR and CCPA enforcement. This leaves media buyers facing lost attribution data, inflated customer acquisition costs, and challenges proving CTV campaign lift. CTV’s walled gardens like Roku and Samsung enable deterministic device IDs for more accurate cookie-free tracking.
What Is Cookieless Attribution and How Does It Work in CTV?
Cookieless attribution employs deterministic household graphs matching IP addresses, device IDs, and app data to link CTV exposures to mobile or web conversions without cookies. Unlike probabilistic cookie methods at 70-80% accuracy, it achieves 1:1 precision using first-party signals. CTV’s high completion rates and premium ecosystems support precise household-level tracking.
How Does Starti’s OmniTrack Deliver 91% Accuracy Without Cookies?
OmniTrack maps IP addresses, CTV device identifiers like Roku and Samsung, and mobile app data into deterministic household graphs for 1:1 connections. It tracks journeys from TV impressions to smartphone purchases or web sign-ups with <0.7% error margin. Full transparency logs every impression’s source, device, timestamp, and outcome, aligning with Starti’s performance-only pricing for verified results.
