MFour Introduces Full-Funnel iOOH™ Attribution for Out-of-Home Advertising

Links verified exposure to app installs, website actions, in-store foot traffic—and reports alongside brand lift in one integrated readout.

IRVINE, Calif., Oct. 16, 2025 /PRNewswire/ -- MFour Data Research, the leader in measuring the real-world impact of out-of-home (OOH) advertising, today launched an Attribution add-on to its iOOH™ Brand Lift solution, bringing true full-funnel measurement to OOH by linking verified ad exposure to app installs, website actions, and in-store foot traffic - all delivered in a single, executive-ready report.

"OOH measurement isn't just for awareness anymore. With iOOH™ Attribution, marketers can prove—and scale—what OOH really drives: installs, site actions, store visits, and brand lift, all verified against real, opted-in consumers," said Chris St. Hilaire, CEO of MFour Data Research. "That clarity turns OOH into a performance channel you can optimize with confidence."

The iOOH™ solution provides validated brand-lift metrics for OOH campaigns by measuring attitudinal change based on verified exposure to advertising. Exposure is validated using MFour's opted-in, location-enabled consumer panel and connected to outcomes across app, web, and location via MFour's unified consumer ID.

The new iOOH™ Attribution add-on specifically quantifies behavioral change - linking exposure to user-level app activity, website actions, and foot-traffic patterns.

"With the largest, all-mobile, opted-in consumer panel in the U.S. - sharing app, web, and location signals and participating in surveys - we can directly connect exposure to behavior. No more inference," St. Hilaire added. "Later this month, we'll introduce purchase data, further closing the path-to-purchase loop and giving advertisers a complete view of ROI."
