Three layers.
1. Business outcomes. Cost per conversion for Demand Gen performance; Brand Lift Study results (Ad Recall, Awareness, Consideration, Favorability, Purchase Intent. Pick up to 3 per study); Meridian Studio Marketing Mix Modelling contribution if running enterprise-grade attribution.
2. Attribution caveats stated up front. 'Views' was renamed 'TrueView views' in October 2025; reports written before then use the legacy term. Last-click on YouTube under-credits the mid-funnel role typical of brand video; Brand Lift plus Meridian GeoX for geo-incrementality is the causal chain.
3. The bets. Which Demand Gen campaigns scaled, which Shorts deep-linked creative converted, which YouTube Select reservations earned their place, what Custom Sponsorships (Brandcast 2026) tested into. Brandcast 2026 cited Coach: +60 percent Gen Z awareness, 6x consideration in one quarter. That is the calibre of brand-lift result that justifies YouTube as a board-grade investment.
