Programmatic DOOH: Buying Out-of-Home Like a Digital Channel

What is programmatic DOOH?

Programmatic DOOH is impression-based buying of digital out-of-home with real-time decisioning — the same mechanics as display or video programmatic, applied to physical screens. Instead of negotiating a lease for a specific face, you set targeting parameters, a CPM bid, and a budget. The platform routes impressions across matching inventory as they become available.

How does the programmatic DOOH technical stack work?

The chain is DSP → SSP → publisher screen network. Major SSPs in DOOH include Vistar Media, Place Exchange (now part of Broadsign), and Hivestack. Major DSPs with DOOH access include The Trade Desk, DV360, and several specialized DOOH platforms. Not all DSPs have equal DOOH access — screen networks vary by SSP relationships. The programmatic chain for DOOH still has more friction than display because screens have physical characteristics: minimum display durations, loop structures, and installation-specific specs that do not exist in digital. In November 2025, Broadsign acquired Place Exchange, creating the largest programmatically accessible DOOH inventory network globally at 1.8 million screens.

What can you target programmatically in DOOH?

How much does programmatic DOOH cost?

CPMs range from $3–$8 for mid-market venue types (gas stations, convenience stores, pharmacies) to $8–$20 for premium environments (airports, office buildings, high-traffic urban panels). Top-tier inventory in major markets can exceed $30 CPM. Programmatic rates are generally lower than equivalent direct buys for standard inventory. For programmatic-guaranteed premium placements, rates converge with or exceed direct.

What can programmatic DOOH not do?

It cannot guarantee your ad plays at a specific moment — you are buying audience share, not a fixed timeslot. It cannot guarantee immediate delivery after launch — screen loops mean some latency between campaign activation and first impression. It cannot fully replace direct for exclusive premium placements that publishers do not make available programmatically. And it cannot match the individual precision of cookie-based mobile targeting — it works at the location and cohort level, not the individual device level.
