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?

Rates are set per publisher, per market and per flight, so there is no single programmatic DOOH price. As a rough illustration of how the market is usually tiered — not a Goldfish quote — mid-market venue types such as gas stations, convenience stores and pharmacies price below premium environments such as airports, office towers and high-traffic urban panels, and spectaculars in major markets sit above both. Programmatic rates are often lower than an equivalent direct buy for standard inventory; for programmatic-guaranteed premium placements they converge with or exceed direct. Ask for a quoted CPM and any platform or media fees in writing for the specific screens on your plan.

A buying checklist before you activate

This is the sequence we run with brands and agencies. Each step produces something you can check before money moves.

1. Write the brief. Markets or store addresses, flight window, budget, audience objective, venue preferences and the creative formats you can produce.
2. Get a dated inventory list and a map. Screens, publishers and venue types as of a stated date — listed inventory, not a guarantee of availability for your flight.
3. Get costs in writing. Quoted CPM or total cost for those screens, plus any platform, data or creative fees.
4. Confirm creative specs with the publisher. Resolution, file type, spot length and delivery deadline for the placements on the plan, not a generic spec sheet.
5. Activate the deal. Deal IDs synced into the buying platform, targeting matching what was agreed, creative approved before the first day of flight.
6. Agree reporting up front. What you will receive, at what cadence, and which numbers are which.

Keep three things separate in that reporting. Ad plays are how many times the spot was shown on a screen. Audience impressions apply an estimated multiplier for how many people were likely in view — they are modelled, and they are not unique people. Measured outcomes — store visits, brand lift, search or site activity — come from a separate measurement method and are the only figures that speak to results.

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.
