The leader in out-of-home advertising measurement.
Measure OOH effectiveness with validated, exposed consumers. Quantify upper-funnel with brand lift surveys and lower-funnel with attribution to prove how out-of-home drives performance across your media mix.
See what your OOH campaigns really drive.
Traditional OOH measurement relies on foot traffic, impressions, or recall alone. Those metrics don't prove impact. iOOH™ delivers the full picture — from the consumers who were genuinely exposed to the outcomes that follow.
Finally, clarity in out-of-home measurement
Validated Ad Exposure

GeoValidated® TechnologyBrand Lift That Matters
Move beyond awareness alone. Our OOH brand lift survey measures changes in recall, favorability, and purchase intent — directly tied to the consumers who were exposed.
Surveys Within 24 HoursFull-Funnel Attribution
Link OOH exposure to real outcomes including app installs, website activity, store visits, and consumer behavior for true performance metrics.
Cross-channel AttributionAccurate ROI Measurement
Assign clear, evidence-based ROI to OOH media. Justify spend and refine future strategy with confidence using normative benchmarks.
Evidence-based ROIHow we measure OOH impact
iOOH™ combines validated exposure, real consumer feedback, and behavior data to deliver insights that reflect what people actually do after seeing your ads.
Media units are geofenced to create precise exposure zones around billboards, transit shelters, and digital displays.
Consumers who cross the geofence are passively identified as exposed — the validated test group, via GeoValidated® technology.
Exposed consumers receive a survey through Surveys On The Go® — capture sentiment at the Point of Emotion®.
Connect that validated exposed audience to real downstream behavior — store visits, web traffic, and app activity — to prove the outcomes your OOH actually drove.
Full-funnel attribution for OOH: foot traffic, web, and app — all in one report.
An OOH brand lift survey measures test-vs-control impact across four KPIs — recall, consideration, intent, and likelihood to recommend.
