Why Is Cookie Deprecation Breaking CTV Attribution?
The third-party cookie sunset in 2025–2026 creates attribution gaps in legacy CTV pipelines, leading to unverified impressions and CPM waste. Brands struggle to prove journeys like Roku views to iPhone purchases, face GDPR/CCPA risks, and rely on probabilistic models with less than 70% accuracy. Starti’s performance-only pricing ensures payment solely for installs and sales, aligning incentives perfectly.
What Are Privacy-First Attribution Models in CTV?
Privacy-first CTV attribution uses deterministic household graphs linking CTV devices via shared IP/hashes, UID2 for anonymized IDs, first-party data matching, and view-through conversion tracking. These methods avoid PII collection, relying on contextual and household-level signals for non-invasive accuracy.
| Attribution Type | Accuracy | Privacy Compliance | Cross-Device Match Rate | Cost Model |
|---|---|---|---|---|
| Probabilistic | <70% | Variable | Low | CPM-based |
| Deterministic | 80-85% | High (GDPR/CCPA) | Medium | CPM or performance |
| Starti OmniTrack | 91% | GDPR/CCPA fully compliant | High via household graphs | Pay only for results (installs/sales) |
