These days, marketers no longer just buy media space—they buy audiences. With growing scrutiny over online advertising accuracy, reliable audience measurement has never been more crucial. Accurate measurement is essential for planning, trading, and evaluating campaigns. In this arena, Out-of-Home (OOH) is uniquely positioned: not only is it the oldest medium, but it is also one of the most precisely measured.
Global Industry Standards
Apart from television, OOH is the only medium with globally accepted audience measurement standards. Sponsored by the research authority ESOMAR and endorsed by major industry bodies such as the World Federation of Advertisers (WFA), the European Association of Communications Agencies (EACA), and the 4As, these standards ensure consistency, reliability, and transparency.
At Moving Walls, we implement these standards through our proprietary Moving Walls Measurement Framework, which allows marketers to capture a complete picture of audience movement and engagement, ensuring that campaign insights are actionable and comparable across markets.
By measuring campaigns systematically—before, during, and after deployment—advertisers can generate robust, actionable insights and build a sophisticated understanding of OOH audience behavior.
Before the Campaign: Audience Measurement
Population
Effective measurement begins with defining the population coverage of a campaign. This includes both residents and transient audiences within the targeted geographic area. For instance, a travel brand deploying ads in tourist-heavy zones will capture both local and visiting populations, providing richer audience data.
Our platform allows marketers to project campaign reach using verified, relevant population sources, helping identify target audiences for segmentation, geofencing, attribution, and retargeting. The goal is simple: maximize the number of relevant eyes on your campaign.
Mobility/Movement Behaviours
Understanding how audiences move within a given area is essential. Movement types—by car, taxi, train, bus, ferry, motorcycle, or on foot—inform the placement and timing of campaigns.
For example, in dense urban areas, where public transport dominates, deploying ads at bus or train stations ensures higher visibility among commuters. By analyzing movement patterns, Moving Walls allows marketers to select locations with the highest audience engagement potential, optimizing both reach and relevance.
During the Campaign: Know the Business Rules
Proof of play (PoP)
Real-time validation is critical. Without reliable proof of play, impression data is meaningless. At Moving Walls, PoP is standardized and automated, ensuring marketers have transparent, verifiable evidence that creatives were displayed as intended.
Additional verification options include third-party audits or external cameras, but our platform’s automated reporting significantly reduces manual effort while increasing trust and accountability.
KPI Measurement
Clear KPIs allow marketers to measure campaign effectiveness comprehensively:
- Brand Lift: Tracks shifts in awareness, perception, and purchase intent.
- Foot Traffic: Measures physical visits to stores or locations via location-enabled devices.
- Online Engagement: Includes website visits, searches, and interactions triggered by OOH exposure.
- Social Impact: Monitors hashtag usage, shares, and social media mentions after seeing the OOH campaign.
Moving Walls integrates these KPIs into one dashboard, allowing marketers to see campaign performance in near real-time and adjust strategy if needed.
After the Campaign: Extending OOH’s impacts
Mobile
OOH campaigns are most powerful when integrated with mobile engagement. Smartphones are indispensable, and 66% of users take online action after seeing OOH ads.
Marketers can extend campaigns with contextual mobile content via QR codes, links, or push notifications. Mobile geofencing enables ads to reach users in hyper-local areas, reinforcing OOH messaging and driving foot traffic.
Key capabilities through Moving Walls include:
- Audience segmentation by demographics, location, and behavior
- Geo-conquesting and geo-farming for competitive targeting
- Attribution tracking for impressions that lead to physical visits
- Retargeting for ongoing engagement after initial exposure
For example, a retail campaign can reach a commuter near a store with an OOH ad, then deliver a follow-up mobile promotion to drive store visits—all orchestrated within our platform.
Social
Integrating OOH with social media amplifies reach and engagement. Adding hashtags or social prompts encourages audiences to interact online, providing marketers with permission-based access to insights.
OOH campaigns drive stronger online activation than radio or print, with measurable increases in searches, page visits, and social posts. For instance, combining OOH with Facebook ads can generate incremental sales while boosting likelihood to purchase.
Our platform supports both one-way (informational) and two-way (interactive) social programs, enabling marketers to capture feedback, refine messaging, and enhance campaign effectiveness.
