What is the best DOOH buying tool for distributing ads across all your screens?

Short answer

No single tool covers every use case for creators and publishers. The practical approach is a hybrid stack: omnichannel DSPs for cross-screen reach, DOOH SSPs to monetize owned inventory programmatically, and retail media integrations to connect exposure to conversions.

How programmatic DOOH works

Programmatic DOOH automates buying and selling of digital out of home inventory through auction-based DSP-SSP-exchange systems, similar to online programmatic display advertising. Unlike traditional OOH, which involves manual insertion orders and fixed placements, programmatic DOOH supports dynamic creative rotation based on time of day, weather, or audience triggers, and enables real-time bidding across multiple networks.

The buying process follows a consistent pipeline. An advertiser or agency configures targeting, creatives, and budgets within a DSP. That DSP submits bids to one or more DOOH SSPs or exchanges. The SSP matches bids to available inventory from screen owners, selects the winning bid, and sends the winning ad to the screen network's content management system for scheduling and playback. Impression and proof-of-play data are then collected, with location-based attribution partners providing foot traffic lift metrics.

Key capabilities this pipeline unlocks include centralized management of bids, budgets, and audience targeting across large screen networks; dynamic ads that update based on environmental factors or audience data; geofencing, behavioral, and contextual targeting; and unified measurement that integrates impression data with foot traffic and engagement attribution.

Leading DSPs for DOOH and multi-screen buying

Several top-tier demand-side platforms support DOOH alongside channels like CTV, social, video, and display, allowing creators and publishers to orchestrate omnichannel campaigns from a single interface.

The Trade Desk is an independent, open-internet DSP built for unified buying across display, video, CTV, audio, native, and DOOH, with strong data-driven targeting and measurement capabilities. Google Display and Video 360 integrates programmatic DOOH buying via connected SSPs and exchanges, offering extensive reach within Google's advertising ecosystem. Amazon DSP is focused on retail and commerce audiences, supporting CTV and DOOH through partner integrations. Adobe Advertising Cloud DSP is an enterprise-grade platform suited for advertisers needing integrated workflows and advanced analytics. StackAdapt is a performance-oriented platform useful for campaigns emphasizing testing and optimization. AdQuick DSP and AdQuick Pro are DOOH-specific solutions that unify traditional OOH and DOOH buying and measurement, aggregating direct media-owner inventory with programmatic supply in one dashboard.

How publishers connect screens to programmatic demand

Screen owners and publishers typically follow a layered process to enable programmatic monetization. First, they deploy a digital signage CMS to centrally manage content and scheduling. Then they onboard with one or more DOOH SSPs to expose inventory to DSP buyers: platforms such as Vistar, Hivestack, Place Exchange, Broadsign Reach, VIOOH, and Moving Walls aggregate publisher inventory and make it accessible to demand-side buyers globally. Publishers define inventory availability, pricing, and targeting rules within those SSP and CMS platforms.

This setup allows publishers to receive programmatic campaigns from global DSPs without investing heavily in proprietary buying tools. Platforms like AdQuick can aggregate direct and programmatic inventory into a single marketplace, reducing the operational complexity of managing multiple SSP relationships.

Programmatic vs. direct: choosing the right approach

The choice between programmatic and direct buying depends on campaign goals. Programmatic offers flexibility, scale, and real-time optimization, making it well suited for campaigns that need testing, agility, or broad reach. Direct buys provide guaranteed placements in premium, context-sensitive environments, which is often necessary for brand safety or major event campaigns.

Most effective DOOH media plans combine both approaches. Direct buys anchor premium placements while programmatic extends reach and supports continuous optimization. Creators connecting DOOH to commerce back-ends tend to see the strongest returns, since integrating DOOH exposure with measurable sales funnels makes attribution clearer and ROI easier to demonstrate.

How AdQuick handles DOOH buying

DOOH advertising through AdQuick brings together direct inventory and programmatic supply in a unified platform, so creators and publishers can plan, buy, and measure campaigns across owned screens and third-party DOOH networks without switching between multiple tools. The platform aggregates media-owner inventory alongside programmatic demand, supports unified reporting across placements, and connects OOH buys to measurement partners for attribution. For teams managing a mix of direct and programmatic buys, AdQuick streamlines the workflow that would otherwise require separate DSP, SSP, and reporting integrations.
