The World Out of Home Organization (WOO) has launched Version 2.0 of its Global Out-of-Home (OOH) Audience Measurement Guidelines, introducing a significantly updated framework aimed at strengthening audience measurement standards across the global OOH advertising industry.
The new guidelines were unveiled during the WOO Congress held in London and represent the most comprehensive revision since the first edition was introduced in 2022.
According to WOO, the updated framework draws on the expertise of audience measurement bodies from 28 territories, more than double the number that contributed to the inaugural edition. The 160-page document also features case studies from 20 measurement organisations, highlighting different approaches to developing audience metrics across global markets.
The revised edition includes updates to its approach and guiding principles, measurement requirements, and refreshed Out-of-Home advertising definitions. It also incorporates contributions from new markets, countries that have completely rebuilt their audience measurement systems since 2022, and others that have significantly enhanced existing frameworks.
WOO noted that the global OOH measurement landscape has evolved considerably over the past four years. Among the notable developments is the widespread adoption of AM4DOOH, which has transitioned from a research initiative into an internationally recognised operational standard across several markets.
Similarly, the Impression Multiplier has moved from being a theoretical concept to a commercially deployed measurement tool, while contemporising—used to align audience models with current behavioural patterns—has expanded into three distinct methodologies tailored to different market requirements.
The organisation also highlighted significant progress in the use of mobile location data for audience measurement. While SDK and telecommunications data previously served mainly as supplementary inputs, many markets now rely on continuously collected passive mobility data as their primary source for audience insights.
For instance, India’s RoadStar platform now measures over 300,000 advertising sites across 2,300 cities using a single continuous data stream. Portugal and the GCC have also introduced advanced audience measurement systems based on continuous panel data and device-level exposure tracking.
In addition, synthetic population modelling—also known as activity-based, agent-based or virtual population modelling—has become increasingly mainstream in audience measurement practices.
Speaking on the updated guidelines, Gideon Adey, Measurement Gurooh at WOO, said the industry has witnessed remarkable progress in audience measurement within a short period.
“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,” he said.
Adey noted that the launch of MOVE in Australia represents a new benchmark for behavioural planning and Digital Out-of-Home (DOOH) trading, adding that the growing adoption of post-campaign audience measurement could signal a major shift in the future of OOH trading globally.
He also commended participating countries for contributing their expertise towards developing the updated global framework.
Also commenting, WOO President, Tom Goddard, described the guidelines as a major industry achievement made possible through collaboration.
“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,” he said.
According to Goddard, the scale of the project would have been difficult for any single company to undertake, noting that the updated guidelines represent WOO’s contribution towards advancing global standards in the Out-of-Home advertising industry.
He urged stakeholders across the industry to leverage the framework to improve audience measurement, transparency and trading practices worldwide.
