Esports overlays — virtual billboards, HUD bugs, replay wipes — now command real budgets, and they deserve stadium-grade measurement. This post shows how to turn gameplay and broadcast footage into qualified exposure seconds using modular computer-vision blocks (logo recognition, OCR, object detection, anonymization), then roll those seconds into two board-ready KPIs: vSOV (visual share of voice) — how much of the screen you truly owned — and CPeS (cost per exposure second) — what you paid for that ownership. Grounded in current IAB gaming guidance, the framework helps publishers and sponsors price, verify, and optimize inventory across titles, proving value with auditable numbers — and giving leadership a practical path to faster deals, cleaner renewals, and better unit economics.
