What are the digital out of home (DOOH) advertising options, and what do they cost?

Short answer

DOOH advertising runs on digital screens across billboards, transit, gyms, elevators, and retail environments. Pricing follows CPM, per-play, or flat-rate models, with CPMs typically ranging from $4 to $25 depending on venue type, location, and audience specificity.

How reach and frequency are measured

Reach counts the unique individuals who have an opportunity to see an ad. Frequency is the average number of times those individuals are exposed during a campaign. Together they form the foundation of how DOOH campaigns are evaluated.

Measurement combines several data sources. Anonymized mobile-device location data maps movement patterns around screens. Footfall counts from sensors or cameras track people passing or dwelling near displays. Visibility geometry modeling assesses viewing angles, distance, and environmental conditions to estimate how likely a person was to actually see the ad. These inputs feed proprietary algorithms, often from industry bodies like GeoPath or individual network providers, that produce unique audience estimates and account for repeated exposures by the same individuals.

Frequency is derived by dividing total impressions by unique reach. For example, 1,000,000 impressions divided by 250,000 unique viewers yields a frequency of 4. Commuter patterns and venue dwell time factor into this calculation to reflect habitual exposure.

An impression is counted when a person is within the screen's viewable cone, the ad is fully displayed, and the screen is active. Because a single DOOH screen can be seen by many people simultaneously, one impression can represent multiple viewers. Attention-adjusted impressions refine raw counts further by weighting them against the probability that viewers actually looked at the ad, inferred from dwell time and gaze direction. Additional metrics include exposure-minutes and look-away rates.

Attribution connects exposure to outcomes. Exposed and unexposed group comparisons isolate a campaign's effect on store visits, app installs, or sales lift. Mobile location data partnerships, web analytics, and sales-lift studies complement each other to tie DOOH exposure to measurable business results.

Pricing models

Three models dominate DOOH buying:

• CPM (cost per thousand impressions): The standard in programmatic and digital screen networks, enabling direct comparison with other digital channels.
• Per play or per spot: Fees based on verified ad plays on specific screens, common for urban panels and highway digital boards.
• Flat-rate or monthly flight buys: Traditional fixed-period purchases for a set location or network.

Typical CPM ranges by venue type:

Open programmatic exchanges can bring CPMs as low as $3 to $6, while premium locations command the higher end of these ranges. Per-play pricing spans a wide range: urban panels run around $0.23 per play, while iconic locations can reach $40 per play.

Monthly campaign budgets vary considerably. A single digital billboard in a non-premium market typically costs $2,500 to $5,000 per month. Marquee placements in top-tier cities run $10,000 to $50,000 or more per month. Multi-screen agency-managed campaigns often carry minimums of $5,000 to $10,000.

What drives DOOH costs up or down

Several factors shape where a buy lands within these ranges:

Location and visibility: Premium intersections, highway corridors, and dense urban cores carry higher prices because of greater footfall and longer dwell times.

Venue type and audience captivity: Gyms, elevators, bars, and waiting areas command premium CPMs because audiences are stationary and attentive for extended periods.

Audience specificity: Targeting affluent or niche demographics, such as office elevator riders in financial districts, increases cost relative to broader placements.

Dayparting: Peak commute hours and evening slots cost more than off-peak times.

Share of voice and creative length: Higher rotation frequency and longer ad spots raise total spend.

Buying method: Programmatic buys generally reduce CPMs and require smaller minimums. Direct premium buys cost more but guarantee specific placements and share of voice.

Cost effectiveness and ROI

DOOH carries structural advantages for impression quality. It is less susceptible to ad fraud, bots, and ad blockers than most online channels. High-attention physical environments tend to produce stronger recall and downstream action.

Reported performance benchmarks suggest DOOH conversion costs can come in below social media equivalents: incremental store visit costs as low as $0.82 and online purchase costs around $5.75 per conversion, compared to paid social CPAs that commonly range from $15 to $40. These figures come from platform and aggregated campaign reports and will vary by category and execution.

OOH-to-online sequencing and retargeting are commonly used alongside DOOH to amplify impact and measure cross-channel effects, connecting physical exposure to digital behavior through matched audiences and mobile location signals.

How AdQuick handles DOOH advertising

DOOH advertising through AdQuick gives buyers access to digital screens across venue types, from billboards to transit to retail environments, through a single planning and buying interface. Campaigns can be structured as programmatic buys for flexible budgets and real-time optimization, or as direct placements for guaranteed premium inventory. Measurement integrations pull in location data and attribution reporting so reach, frequency, and conversion outcomes are visible in one place rather than scattered across individual network reports.
