Digital Out-of-Home
Programmatic advertising displayed on digital screens in public spaces such as billboards, transit stations, malls, and airports, combining physical location targeting with automated, data-driven ad delivery.
Digital out-of-home (DOOH) brings programmatic buying capabilities to physical world advertising. Digital screens in high-traffic locations can now be purchased through DSPs using the same targeting, scheduling, and measurement tools used for online advertising. Campaigns can be triggered by time, weather, location-based audience data, or real-time events.
For growth teams, DOOH adds a physical touchpoint to predominantly digital acquisition strategies. AI enables dynamic creative that adapts to context, such as showing hot coffee ads on cold mornings or promoting nearby store locations based on the screen's geography. The measurement challenge for DOOH is attributing physical ad exposure to digital conversions. Solutions include mobile device ID matching, which identifies devices that were near a DOOH screen and later converted, and lift studies that compare conversion rates in exposed versus unexposed geographic areas. Growth engineers should approach DOOH as a complement to digital channels rather than a standalone performance channel, using it to increase reach and reinforce messaging among target audiences in specific geographic areas.
