San Antonio programmatic DOOH market — at a glance
Trillboards operates a tier-1 market digital out-of-home network in San Antonio, Texas, with 202 active screens delivering programmatic ads across 6 venue categories as of May 11, 2026. The inventory mix here leans 91% retail stores — a fingerprint that shapes the audience archetype, dwell-time distribution, and CPM clearing band for every buyer running creative against this market.
San Antonio's DOOH inventory skews heavily toward retail and entertainment along the I-35 and I-410 commercial corridors. The South Texas Medical Center and the SeaWorld–Lackland AFB corridor together produce a year-round visitor flow that lifts off-peak fill rates above the Texas median.
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 San Antonio comes from mixed-format venues (8 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 entertainment venues (4 screens). Together with the primary and secondary categories, this three-venue spine accounts for the majority of San Antonio's active inventory and underpins the city's audience-archetype diversity score of 6 categories represented.
Texas state-wide DOOH activity (1441 active screens across 265 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 $5–$14 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. San Antonio-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 San Antonio.
Buyers reach San Antonio 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 6 distinct San Antonio 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 tier-1 market market like San Antonio, expected daily reach scales with the venue-category mix and the active screen count of 202; buyers should plan minimum flights of three to five days to absorb day-of-week audience-archetype variance.
