|---|---|---|

Audience Measurement and Attribution
Historically, measurement relied on impressions estimates. In 2026, measurement has evolved. GPS-based measurement tracks movement through areas. Mobile data providers provide location signals. Attention measurement estimates whether people notice displays.
Attribution remains challenging because impact occurs asynchronously. Organisations measure through conversion lifting studies, comparing sales in markets with advertising against control markets.
DOOH Creative and Campaign Strategy
Effective creative uses large visuals, concise messaging, and strong contrast. Dynamic creative optimisation changes content based on time, weather, or data signals. Sequential storytelling creates narrative journeys across locations.
DOOH Integration with Digital Ecosystem
Leading organisations integrate DOOH with digital advertising. DOOH exposure drives online search, enabling measurement. Customer data platforms identify exposed consumers for follow-up digital advertising.
