Seattle programmatic DOOH market — at a glance
Trillboards operates a frontier-tier market digital out-of-home network in Seattle, Washington, with 6 active screens delivering programmatic ads across 4 venue categories as of May 11, 2026. The inventory mix here leans 33% retail stores — a fingerprint that shapes the audience archetype, dwell-time distribution, and CPM clearing band for every buyer running creative against this market.
Seattle DOOH inventory leans into office-building and gym placements clustered around the South Lake Union, Downtown, and Capitol Hill corridors. The Amazon-and-tech employment density skews the audience B2B-leaning during weekday daytime; weekend mix shifts toward retail and entertainment along Pike/Pine and Ballard.
Retail placements deliver the highest fleet representation in this market. Foot-traffic patterns inside grocery, big-box, and specialty retail produce an unusually steady impression cadence — buyers running CPG, retail-pharmacy, and back-to-school creative explicitly target these formats. Secondary venue exposure in Seattle comes from salons (2 screens), which adds an audience layer that buyers running cross-format creative routinely exploit — the secondary footprint absorbs incremental impression delivery without overlapping the primary venue's audience archetype. Tertiary venue coverage includes bars (1 screens). Together with the primary and secondary categories, this three-venue spine accounts for the majority of Seattle's active inventory and underpins the city's audience-archetype diversity score of 4 categories represented.
Washington state-wide DOOH activity (33 active screens across 19 cities) places it as a strong regional CPM market — programmatic clearing prices outperform the national median through every quarter. Programmatic clearing in this state typically ranges $6–$15 CPM, with the high end reflecting prime-window prime-venue inventory — bars, entertainment venues, and downtown office-tower placements during the 11 AM-2 PM and 5-9 PM windows. Seattle-specific clearing prices vary by venue format and time-of-day, but the state-level distribution gives buyers a credible baseline for first-time campaign-planning estimates against Seattle.
Buyers reach Seattle DOOH inventory through Trillboards' partner-side programmatic integrations (OpenRTB 2.6 with native VAST 4.x rendering) or directly via the Trillboards Connect SDK for direct-sold flights. Geo-targeting accepts state, DMA, city, and ZIP-radius filters; venue-category filtering uses the IAB Audience Taxonomy 1.1 codes with 4 distinct Seattle categories available for inclusion or exclusion. Impression verification rides on proof-of-play telemetry from each screen — every billable impression is independently confirmed by the screen's playback log, not just the SDK's quartile callbacks. For a frontier-tier market market like Seattle, expected daily reach scales with the venue-category mix and the active screen count of 6; buyers should plan minimum flights of three to five days to absorb day-of-week audience-archetype variance.
