Programmatic DOOH pulls together terminology from three different worlds: traditional out-of-home media, digital ad tech, and increasingly, retail and mobile data. That mix is exactly why the jargon gets confusing fast. This glossary collects the terms that come up most often across our coverage of the space, organized by category, with a link to a deeper explainer wherever we've written one.
Fundamentals
OOH (Out-of-Home): Any advertising shown outside the home, including traditional static formats like printed billboards and posters.
DOOH (Digital Out-of-Home): Out-of-home advertising delivered on a digital screen rather than a static, printed surface. See our complete guide to DOOH advertising for the full picture.
pDOOH (Programmatic DOOH): DOOH inventory bought and sold through automated, real-time technology rather than manual, direct-sold deals. See what pDOOH is and how it works.
Programmatic OOH: Sometimes used interchangeably with pDOOH, referring broadly to automated buying across the out-of-home category. See what programmatic OOH is and its advantages.
Buying & Trading
DSP (Demand-Side Platform): The platform advertisers use to plan, bid on, and manage programmatic DOOH campaigns. See our comparison of the best programmatic DOOH DSPs.
SSP (Supply-Side Platform): The platform that connects a media owner's screen inventory to the programmatic ecosystem, making it available for bidding.
RTB (Real-Time Bidding): The auction mechanism underlying programmatic buying, where impressions are bid on and won in real time rather than negotiated manually. Covered in depth in how programmatic DOOH buying actually works.
Self-Service: A buying model where advertisers set up and launch campaigns directly through a platform, without an agency or broker. See self-service programmatic DOOH for small and mid-size advertisers.
Managed Service: The traditional buying model where an agency or media owner's sales team plans, negotiates, and manages the campaign on the advertiser's behalf.
Direct-Sold: Inventory purchased through a manual, negotiated deal rather than an automated auction.
Creative & Technology
CMS (Content Management System): The software layer that schedules, uploads, and manages what plays across a network of screens. See our guide to digital signage software for programmatic DOOH.
DCO (Dynamic Creative Optimization): Creative that automatically changes based on real-time conditions like weather, time of day, or live events. See dynamic creative optimization triggered by weather and time.
Creative Specs: The technical requirements (resolution, file type, duration, color mode) a piece of creative must meet to run on a given screen network. See our creative specs and ad formats guide.
AI-Powered Optimization: Machine learning used to inform targeting, bidding, and creative decisions in real time. See AI-powered pDOOH and machine learning in advertising.
Media Player: The physical hardware device connected to a screen that receives and displays scheduled content.
Measurement & Verification
Proof-of-Play: A timestamped log confirming that an ad actually played, when, and on which screen.
Viewability: A measure of whether an ad was actually visible and exposed to a potential viewer, based on factors like dwell time, sightlines, and obstructions rather than a simple pixel count. See ad verification, viewability, fraud, and brand safety in programmatic DOOH.
Attribution: Connecting a DOOH ad exposure to a downstream outcome, like a store visit or online conversion. See measuring pDOOH success, metrics, and attribution.
Footfall Attribution: A specific form of attribution measuring foot traffic to a physical location after ad exposure. See location intelligence and footfall attribution.
Ad Fraud: Invalid or misrepresented impressions, in DOOH's case typically involving spoofed location data rather than bot traffic. Covered alongside viewability and brand safety in our verification guide above.
Brand Safety: In DOOH, this refers to real-world context risk (an ad running near a live incident or sensitive event) rather than online content adjacency.
Geopath: The primary audience measurement currency body for US out-of-home advertising, publishing modeled impression and reach figures for individual screens and networks.
MRC (Media Rating Council): The independent, non-profit body that sets accreditation standards for media measurement products, including out-of-home. Learn more directly at the Media Rating Council's official site.
Audience & Targeting
Location Intelligence: Using location data to inform targeting, measurement, and campaign strategy. See location intelligence and footfall attribution.
Retail Media Network: A retailer's owned advertising inventory, increasingly including in-store and near-store DOOH screens. See retail media networks and programmatic DOOH.
Dayparting: Scheduling different creative to run at different times of day based on expected audience or context.
First-Party Data: Data a brand or retailer collects directly from its own customers, increasingly used to inform DOOH targeting through retail media partnerships.
Market & Business
CPM (Cost Per Mille): The cost of one thousand ad impressions, the standard pricing unit across most of DOOH and digital advertising.
ROI (Return on Investment): The financial return generated relative to campaign spend. See our comparison of programmatic DOOH versus traditional billboard ROI.
Spectacular: A large-format, high-impact DOOH display, typically in premium locations like Times Square, commanding premium pricing.
Street Furniture: Smaller-format DOOH inventory like bus shelters, kiosks, and urban panels, often a lower-cost entry point for local advertisers.
Interactive DOOH: Screens that respond to touch, motion, or nearby devices rather than simply displaying static or looping content. See interactive digital screens in outdoor advertising.
Sustainable DOOH: Practices and technology reducing the environmental footprint of out-of-home advertising, such as eliminating printed changeouts. See the future of sustainable advertising in pDOOH.
IAB (Interactive Advertising Bureau): The industry body that publishes measurement and standards guidance referenced throughout digital and DOOH advertising. Visit the IAB's official site for their published standards.
Audience Segments & Use Cases
Gen Z / Millennial Targeting: Strategies aimed at younger, more mobile-first audiences who tend to ignore traditional digital advertising formats. See reaching Gen Z and Millennials through pDOOH.
SMB DOOH: Smaller-scale, locally-targeted DOOH campaigns aimed at small and mid-size businesses rather than national brands. See affordable DOOH advertising for retail and restaurants and our guide to self-service programmatic DOOH.
