Which omnichannel DSPs support cross-channel attribution for DOOH?

Short answer

StackAdapt, AdQuick, and Adomni connect programmatic DOOH to CTV, display, and mobile, enabling cross-channel attribution through audience-level lift methodologies. Because DOOH lacks user-level identifiers, attribution relies on cohort analysis and proxy signals rather than deterministic click tracking.

Why DOOH attribution works differently from other digital channels

Unlike search or social, DOOH cannot attach a conversion pixel to a specific person who saw a billboard. Attribution instead works at the audience or cohort level, using aggregated exposure data and downstream behavioral signals. Three core frameworks underpin most current approaches:

• Screen-to-screen: Exposure at a DOOH screen is correlated with visits or engagements at another screen, such as a retail entrance, using anonymous sensing technology. Lift is reported for cohorts, not individuals.
• Screen-to-store: DOOH audience measurement is combined with footfall counters at physical store entrances to estimate incremental visits driven by exposure.
• Screen-to-mobile cohort: Opt-in mobile panels model correlations between DOOH exposure and subsequent mobile app or web visits at the cohort level, preserving privacy compliance.

QR codes, unique URLs, and promo codes embedded in DOOH creatives act as offline-to-online triggers that feed into standard digital analytics platforms, allowing DOOH exposure events to appear alongside search, social, and email in unified reports.

Industry bodies including the Media Rating Council, GeoPath, Outsmart, FEPE, and AGMA set the measurement guidelines and audit standards that govern these methods, emphasizing third-party auditability, unique-person counting, and no personal data capture.

The leading omnichannel DSPs and what they offer

StackAdapt is an omnichannel DSP that activates programmatic DOOH alongside CTV, display, and other channels within a single platform. Its cross-channel attribution goes beyond last-touch, showing how DOOH introduces, reinforces, or closes conversions and how it sequences with other media in the marketing mix.

AdQuick is a DOOH-focused DSP and marketplace that aggregates inventory from major DOOH supply-side platforms and direct media owners. Its reporting ties screen exposure to store visits and attributed conversions, and it supports device-level retargeting across CTV and display for cross-channel sequencing.

Adomni connects DOOH with CTV, online video, and mobile retargeting, providing visibility into reach, geographic performance, audience engagement, and incremental lift in a unified outcomes view.

Together, these platforms transform DOOH from a siloed, impression-based channel into one with measurable performance metrics aligned to the rest of a digital media plan.

Fitting DOOH into broader attribution stacks

Omnichannel DSPs do not replace existing attribution infrastructure; they feed into it. Three integration approaches are common:

GA4 Data-Driven Attribution: DOOH exposure events such as QR scans or store visits can be tracked as conversion events in GA4, which then apportions credit across DOOH, paid search, social, and other channels. Reliable data-driven attribution requires sufficient conversion volume, roughly 400 conversions per 28-day window, for statistical validity.

Media Mix Modeling (MMM): MMM provides aggregate, longer-term analysis of each channel's contribution, including DOOH, compensating for the absence of deterministic user-level data. It is typically used alongside data-driven attribution and incrementality testing to validate causal impact and guide budget allocation.

Incrementality testing: Controlled experiments isolate the causal effect of DOOH exposure on conversions, complementing the probabilistic estimates that audience-level attribution produces.

Platforms such as StackAdapt, AdQuick, and Adomni structure their exposure and outcome data exports to feed cleanly into these models, enabling holistic budget decisions across channels.

How AdQuick handles DOOH attribution

DOOH advertising through AdQuick is designed to sit inside a broader omnichannel plan rather than operate as a standalone channel. The platform aggregates inventory across major DOOH supply-side platforms and direct media owners, activates campaigns programmatically, and produces consolidated reporting that connects screen exposure to footfall lift and attributed online conversions. Retargeting across CTV and display based on DOOH exposure cohorts extends the campaign's measurable reach beyond the physical screen.

How we evaluate

This comparison draws on AdQuick marketplace activity: 1,700+ media owners across 182 markets, informed by more than $500M in campaigns transacted on the platform.

Criteria: Coverage, pricing transparency, format breadth, and measurement support.
