Confirmed OOH impressions and what makes a single view real

standing in front of a screen confirms a playback event across potentially thousands of devices, each with independent hardware, connection and environmental conditions. IAB and IAB Europe published joint In-Store Retail Media Definitions and Measurement Standards in December 2024, and established a four-step view ladder — Ad Play, Gross Impression, Opportunity To See and Likelihood-To-See — to formalize what different levels of confirmed delivery actually mean.

What must apply for a single OOH impression to be real?
