Outdoor DOOH in the DOOH ecosystem
Outdoor DOOH is the classic out-of-home segment that buyers associate with billboards and street kiosks. On the Trillboards network this category includes pedestrian-facing screens in NYC (heavy concentration in the Bronx and outer boroughs), Chicago, and Los Angeles, as well as a smaller international footprint. The audience archetype skews toward urban commuters, mixed groups, brief dwell per impression, but enormous reach: 985 daily impressions per screen makes outdoor placements the lowest cost-per-thousand-eyes on the platform. Buyer demand is dominated by national consumer brands (telecom, automotive, packaged food) plus political and cause campaigns during election cycles. The Trillboards OpenRTB feed makes this inventory available to standard DOOH DSPs via the OAAA-recognized programmatic protocols.
How the buy executes at outdoor dooh
Each screen runs the Trillboards kiosk app on an open OpenRTB 2.6 connection to our SSP. Roughly every 30 seconds, the device fires an ad request carrying the IAB DOOH inventory descriptor, venue category, location, screen format, plus the live audience measurements from the on-device CV pipeline.
Demand-side platforms bid in under 100 ms. The winning creative ships back, plays in the device's native VAST player, and confirms playback with a signed proof-of-play receipt. Those receipts reconcile daily against partner-reported numbers, which is the record we bill against.
We serve first-party and third-party VAST, OMID viewability where the creative declares it, and device-signed proof of play, meeting the OAAA measurement standards and the IAB DOOH 1.0 specification. Buyers on our OpenRTB endpoint target outdoor dooh through the IAB Audience Taxonomy and the Trillboards segtax=600 namespace, and receive no per-screen identifiers in the bid request.
If you own the venue
Outdoor placement operators, typically small ad-network owners or property managers with public-facing storefronts, host Trillboards screens at street-level. Trillboards handles all programmatic demand wiring; the operator receives a monthly revenue share with no per-impression accounting overhead.
Where these numbers come from
Screen counts, floor CPM, daily impressions and city rankings are aggregated from the Trillboards PostgreSQL system of record (earner_screens, filtered to status = 'approved') joined to the venue taxonomy, snapshotted 2026-05-11 and rebuilt monthly. Floor CPM is the screen-level minimum; cleared CPMs typically run 20–40% higher with demand. Audience index, price and market count come from the live curated catalogue. This page publishes no per-screen, partner or device identifiers.
