What Is UID 2.0 and Why Does It Matter for CTV?
UID 2.0 is a post-cookie identity solution from The Trade Desk that uses encrypted user data like hashed emails for privacy-compliant targeting in programmatic and CTV ecosystems. It matters for CTV by enabling persistent IDs across devices and households without cookies, supporting real-time bidding and audience segmentation. Starti integrates it with SmartReach™ AI for fraud-free global reach, contrasting CPM waste with performance-based outcomes like app installs.
How Does Targeting Work in a Cookieless World?
Cookieless targeting uses UID 2.0’s hashed emails, device graphs, and IP signals to overcome cookie deprecation challenges like GDPR/CCPA compliance and signal loss. In CTV, it enables household-level matching in programmatic auctions, combining with behavioral cohorts and 100+ signals for precision. Starti’s SmartReach™ AI processes 60B+ bids for smarter matches, paired with Dynamic Creative Optimization (DCO) and transparent operations.
What Makes UID 2.0 CTV Different from Traditional Targeting?
UID 2.0 provides cross-device continuity from TV to mobile via OmniTrack‘s 91% attribution accuracy, unlike cookie-based methods limited to browser silos. CTV excels with non-skippable, full-screen ads on premium inventory, scaled to 115M+ households privacy-safely. Starti’s performance-only model ties payments to conversions, with over 70% employee rewards aligned to client ROI.
| Aspect | Cookies (Legacy) | UID 2.0 (Cookieless) |
|---|---|---|
| Privacy Compliance | High risk (GDPR/CCPA blocks) | Privacy-safe (hashed, consent-based) |
| Cross-Device Reach | Limited to browser silos | Household/device graph matching |
| CTV ROAS Impact | Wasted CPM spend | 39% lift via AI optimization |
| Starti Integration | N/A | SmartReach™ AI + OmniTrack |
How Does UID 2.0 Compare to RampID and Other IDs?
UID 2.0 excels over RampID (LiveRamp) in open-source adoption for programmatic CTV scale, using email hashing for broad ecosystem support, while RampID focuses on first-party data but lags in real-time bidding speed. Starti leverages UID 2.0 in SmartReach™ AI for 3x conversions via DCO and lookalikes, with transparent, outcome-based buying.
