Columbus programmatic DOOH market, at a glance
Trillboards operates a growth-tier market digital out-of-home network in Columbus, Ohio, delivering programmatic ads across 3 venue categories. The inventory mix here leans 64% retail stores, a fingerprint that shapes the audience archetype, dwell-time distribution, and CPM clearing band for every buyer running creative against this market.
Columbus DOOH inventory clusters around the Short North arts corridor, the German Village retail footprint, and the OSU campus-adjacent entertainment district. The Ohio State University student audience (60K+ enrollment) anchors a younger demographic skew than the broader Ohio fleet.
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 Columbus comes from entertainment venues, 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 financial branches. Together with the primary and secondary categories, this three-venue spine accounts for the majority of Columbus's active inventory and underpins the city's audience-archetype diversity score of 3 categories represented.
Ohio state-wide DOOH activity places it as a stable regional CPM market with predictable buyer-side demand across QSR, retail, and entertainment verticals. Programmatic clearing in this state typically ranges $4–$11 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. Columbus-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 Columbus.
