Create a CTV audience strategy that blends Automatic Content Recognition (ACR) exposure data with commerce intent from a retail media partner. For [Brand] and the product line [Product], in [Region], using [RetailerDataPartner] and activating via [DSP], define seed audiences, expansion logic, frequency tiers, and suppression rules. Outline how to build a taxonomy (prospects, switchers, loyalists) and use modeled co-viewing to adjust household vs. person-level reach. Establish privacy-safe onboarding and clean-room matching. Output format: (1) Audience taxonomy table (segment, size, data source, eligibility, refresh cadence); (2) Activation workflow diagram description (ACR ingestion → clean room join → deal ID mapping → DSP); (3) KPI framework with baseline [KPIs] and learning agenda; (4) Governance checklist for [PrivacyConstraints].
