Mumbai: The World Out of Home Organization (WOO) has officially launched Version 2.0 of its Global OOH Audience Measurement Guidelines at the WOO Congress in London, marking the most significant update to the medium’s measurement framework since the original guidelines were introduced in 2022.
The updated framework reflects the rapid evolution of audience measurement practices across the Out of Home (OOH) industry and incorporates contributions from measurement bodies across 28 territories—more than doubling participation compared to the first edition.
Spanning more than 160 pages, the updated guidelines include contributions and case studies from 20 measurement bodies, showcasing a wide range of methodologies and approaches to audience measurement across markets.
The revised edition introduces updates across key areas including approach and principles, measurement requirements and refreshed OOH definitions. It also captures the progress made by newly participating markets, territories that have rebuilt measurement frameworks from the ground up since 2022, and mature markets that have substantially modernised existing systems.
Over the past four years, audience measurement practices across the sector have undergone significant transformation.
AM4DOOH, which was previously identified as an emerging research initiative in the original guidelines, has evolved into an internationally adopted operational standard across multiple markets. The Impression Multiplier has moved from theoretical discussion into active commercial deployment, supported by standardised protocols developed by industry measurement bodies.
The report also highlights the evolution of contemporising—the practice of updating audience models to reflect changing behaviour—which has developed from a single pandemic-era methodology into three distinct approaches tailored to different market conditions.
Mobile location data has similarly transformed the measurement ecosystem. While SDK and telecom-based datasets were once supplementary inputs to government audience counts, several markets now rely on continuously collected passive mobility data as a primary source of audience measurement.
India’s RoadStar initiative has emerged as a notable example, measuring 300,000 sites across 2,300 cities using a continuous data stream. Portugal and the GCC have also contributed examples of continuous panel measurement and observed device-level exposure models respectively.
Synthetic population modelling—including activity-based, agent-based and virtual population approaches—has also moved into mainstream adoption across measurement frameworks.
Commenting on the launch, Gideon Adey, Measurement Gurooh, World Out of Home Organization, said, “It is amazing how much has developed over just four years in the world of OOH audience measurement.”
Adoption of the core principles of governance and transparency has spread widely, while the techniques to deliver credible audience data have developed.
“With the launch of MOVE in Australia this year we see a new north star (or southern cross) in terms of the granularity required for behavioural planning and DOOH trading, while the rise of post campaign measured audiences may be just the beginning of a global shift in the way that OOH can be traded in the future.
Appreciation must be given to the contributing nations, who have given their time and knowledge for the greater good of Global OOH — thank you for making these Guidelines possible.”
WOO President Tom Goddard highlighted the collaborative nature of the initiative and the value trade associations can create for industry-wide progress.
He said, “One of the most valuable and unique things a strong trade association can do is get the whole industry together, working for everyone’s benefit.
It wouldn’t have been possible for one company, however large, to have marshalled the resources Gideon and his team have here to create this groundbreaking and much-needed measurement structure.
In any relationship it’s important that both sides give as well as take and this major piece of work might be seen as WOO’s gift to the global Out of Home industry. We should make the most of it.”
With the release of Guidelines 2.0, WOO aims to establish a stronger global benchmark for audience measurement, transparency and accountability, helping markets align around more advanced and consistent approaches to OOH planning, trading and performance evaluation.
