What is programmatic digital out-of-home (pDOOH)?

If your agency or brand uses online advertising, you may already know the basics of programmatic ad buying or have even set up a campaign using a demand-side platform (DSP). But even if the technology is similar, a few features of programmatic DOOH are unique compared to other digital formats, and there are certain factors to consider when integrating pDOOH in your omnichannel strategy – especially if the outdoor space is totally unfamiliar to you.

But what is pDOOH, exactly? Programmatic digital out-of-home, also known as programmatic DOOH or pDOOH, refers to the automated buying, selling, and delivery of out-of-home (OOH) advertising – that’s ads on digital billboards and signage.

Sounds simple? In a way, it is. With programmatic DOOH, computers are automating the sale and delivery of ad content in a similar way to what you see with most online advertising. Buyers will set conditions under which they want to buy media; when those conditions are met, ads are automatically purchased.

However, since programmatic DOOH ads appear out in the world and not on personal devices, your approach to building a programmatic DOOH campaign will likely differ from what you’re used to online.

Here’s a closer look at what programmatic DOOH is and how to use it to its full potential.

What is digital out-of-home (DOOH) advertising? A quick refresher on why DOOH is great in general

Marketers are increasingly seeing the value of DOOH, and it’s reflected in the continued growth of out-of-home advertising. In fact, one-third of all OOH ad spend in 2023 was directed to DOOH — and it’s projected to grow another 10% by the end of 2024. 

So, what is DOOH media? There’s a lot to love, but here are a few standout details.

  • DOOH ads can offer unmatched size: Big digital screens offer a lot of room to execute visually stunning ideas (see our favourite OOH and billboard ads) in a way you can’t match on personal devices. Even smaller DOOH displays, like digital signage, totems, and displays on bus stops, are going to offer a larger canvas with great visual potential. 
  • DOOH is unskippable and ad-block-proof: If people are around a digital display, they’re going to see it. There are no ad-blockers, no below-the-fold positions, and no issue of users switching over to a different app or tab. That’s partly why nine in ten U.S. adults (88%) notice OOH ads, and nearly 80% have engaged with an OOH ad in the past 60 days.
  • (D)OOH supercharges your other channels: Yes, digital out-of-home and traditional OOH advertising are impactful on their own, but they shine when you pair them with other advertising channels. Research from MRI-Simmons and the Outdoor Advertising Association of America found that using OOH alongside other channels can boost reach by as much as 100%.
  • DOOH drives real-world action: A new Harris Poll study reveals that DOOH is the preferred and most motivating medium compared to other forms of advertising. Notably, 76% of recent DOOH ad viewers reported taking action in response to an ad, highlighting its effectiveness in driving consumer behaviour.

pDOOH vs DOOH: Why programmatic digital out-of-home is even better

So take everything great about DOOH and layer extra data, better targeting, and easy access. That’s what you’re looking at with programmatic DOOH. Let’s dig into that in a little more detail.

Programmatic DOOH is DOOH improved by data

  • Programmatic DOOH uses data analytics to provide detailed insights into campaign performance, including audience engagement and effectiveness. 
  • Traditional DOOH campaigns typically rely on less granular data, such as general traffic patterns and location demographics, limiting the ability to tailor and optimize campaigns effectively.

While traditional DOOH relies on more general metrics and lacks the granular data needed for in-depth analysis, programmatic DOOH uses data analytics to provide detailed insights into campaign performance, including audience engagement and effectiveness. This helps advertisers optimize their strategies and improve ROI.

The key to understanding programmatic DOOH is this: programmatic transactions allow you to set specific conditions based on external data that will trigger a DOOH ad slot purchase. The fun thing is that there are virtually no limits to the kinds of data that can be used to trigger content.

There are simple options, like having different creatives delivered based on the time of day. There are also slightly more advanced options, like the weather, daily market performance, or the ongoing results of a sporting event. You can even use live audience information to trigger content that is ideal for the majority of people at a location at any given time.

And, of course, you can use multiple triggers based on multiple data sources to get really granular with your targeting.

This all leads to great things. Using one or more data triggers to drive a programmatic DOOH campaign can open the door to creative and memorable campaigns. Better still, it helps ensure your audience sees your ads at the most relevant times.

Example: See how foodora used weather, time of day, and location data to drive a creative, effective, and very relevant programmatic DOOH campaign.

Programmatic DOOH is faster and more flexible

  • Programmatic DOOH allows advertisers to purchase ad space in real-time through automated bidding platforms, allowing advertisers to adjust their campaigns based on performance, availability, and changing conditions.
  • Traditional DOOH often requires pre-booking ad space, limiting flexibility and responsiveness.

Unlike classic or directly purchased DOOH, pDOOH allows advertisers to buy inventory in near real-time without needing upfront commitments or predefined schedules. This provides a high degree of flexibility and responsiveness, minimizes lead times, and makes optimizing ad placements and adjusting spending on the fly easier. 

Survey results from IAB Australia’s 2024 Attitudes to Programmatic DOOH report show that just over half (52%) of advertisers see programmatic DOOH as a significant or regularly considered part of their activity, and a further 36% have experimented with it. Flexible buying is a key factor, with 68% of agencies and 55% of brand marketers and advertisers citing programmatic flexibility as a major driver for usage. 

Strictly speaking, programmatic doesn’t enable anything that can’t be accomplished with a direct buy. The difference programmatic makes is in terms of speed and efficiency. You can deliver relevant messaging much more quickly and without making repeated direct buys.

In the foodora example above, audiences were delivered different messages at lunch and around dinnertime. They were prompted to go for a nice walk to pick up their food if it was sunny and to treat themselves to delivery when it was raining. The restaurants suggested to them differed depending on where they were located when seeing the ad. All of this was accomplished without additional input from foodora once the campaign had been set up.

Programmatic can help you accomplish similar results for whatever conditions you want to set. As soon as the time is right, you can automatically deliver the right message to the right screen to reach your audience, whoever they are.

Programmatic DOOH is easily accessible through leading DSPs

More and more DSPs are getting on board with programmatic DOOH. It’s making adding DOOH to multichannel campaigns much more straightforward, and we’re already seeing buyers use this opportunity significantly. 

Existing content can often be easily adapted to suit a digital out-of-home display. The medium’s support for dynamic DOOH and adaptive HTML5 formats, in particular, can greatly help buyers reuse existing content from an online and/or mobile campaign in a programmatic DOOH campaign.

As a bonus, programmatic allows you to buy across multiple publishers simultaneously. It’s much quicker and easier to build a programmatic campaign targeting screens across various networks than reaching out to each business individually to coordinate your buy.

As more DSPs begin to support programmatic DOOH and more buyers start incorporating the medium into their campaigns, the format will likely become an integral part of most mainstream media buys.

Measuring the effectiveness and ROI of programmatic DOOH campaigns

Many brands approach DOOH expecting a measurement standard equivalent to the online impression or gross rating point (GRP). However, DOOH media is different. It spans a variety of display types, not just browsers, TVs, or apps, which presents challenges in creating fully standardized metrics. 

Another key difference is that ads are served in a one-to-one environment when you load a web page, so ‘one ad served’ equals ‘one impression.’ By contrast, DOOH advertising is served in a one-to-many environment. A single DOOH ad has the potential to achieve hundreds of impressions. But how can we really know that? And what does a DOOH impression look like anyway? 

Fortunately, several reliable and rigorous measurement methods are available to help make a strong case for DOOH, and these have been bolstered even further in recent years through the growth of programmatic transactions in the DOOH space. 

Key performance metrics to measure the success of pDOOH

OOH is fundamentally a brand awareness medium. There’s lots of evidence that OOH campaigns can have a significant positive impact on metrics such as brand awareness and brand recall. However,  marketers likely also want to measure the impact of adding DOOH to their other channels. 

Technological advancements are now making it possible to obtain reliable, trustworthy, and privacy-compliant data to analyze campaign performance. Understanding which specific metrics you want to track and measure ahead of time will make it easier to design and evaluate the campaign’s overall success.

Some of the top measurement solutions for direct attribution include:

  • Brand lift: Often conducted via surveys broadcasted in geo-locations within a specific zone of the exposed DOOH screens, brand lift studies seek to measure a DOOH campaign’s effect on overall brand metrics like ad recall, awareness and perception, consideration, and intent.
  • Foot traffic attribution: Commonly used by brands with physical locations to measure a lift in store visits post-DOOH exposure, foot traffic studies provide insights into immediate attribution by mapping audience travel patterns before and after they pass specific screens or points of interest.
  • Mobile retargeting/mobile ID passback: Including mobile retargeting in your omnichannel strategy is one of the best ways to amplify your campaign. Data experts specializing in device ID passback capture device IDs when audiences enter defined location boundaries. This data is then analyzed and translated into qualified audience profiles, which can later be retargeted with mobile ads via your DSP. Capturing exposed device IDs can enable additional measurement of how your DOOH campaign impacted other media channels.
  • QR code attribution: QR codes on DOOH ads offer an interactive and accurate way to measure engagement by tracking the number of codes scanned and sequential offers delivered based on interactions. They also allow for A/B performance testing and help measure converted sales that can be directly attributed to each campaign.

Examples of pDOOH in action

Looking for inspiration? Here are two programmatic digital out-of-home advertising examples that show how different agencies and brands have leveraged the medium.

Holt Renfrew: Driving in-store foot traffic & boosting intent

With Nordstrom closing its doors in Canada, Holt Renfrew, the country’s largest fashion and lifestyle retailer, wanted to capitalize on the shutdown of its competitor to regain market share in key customer demographics. More specifically, it wanted to boost consideration and drive consumers to its brick-and-mortar stores nationwide.

The retailer did so by simultaneously launching two large-scale programmatic digital out-of-home campaigns promoting its ‘Holts <3’ sale event, partnering with Havas agency to launch the campaign with Broadsign in major Canadian cities like Toronto, Vancouver, and Montreal.

Sea-Doo: Increasing Purchase Consideration in Florida

Sea-Doo, a brand of personal watercraft and boats manufactured by Bombardier Recreational Products (BRP), recently sought to strengthen brand recognition, purchase consideration, and share of voice in its primary market of Florida. 

To reach its core audience of personal watercraft, pontoon, and fishing enthusiasts, the brand turned to programmatic DOOH — its first experience with the medium. Launched in collaboration with Touché! agency and Broadsign, the DOOH campaign ran alongside other channels like search and social media and resulted in a +144% lift in purchase consideration. The campaign also provided a major boost in brand perception, creating a +130% lift in positive brand image

Educational resources for programmatic DOOH

Though programmatic DOOH has come a long way, even in the past couple of years, the industry still needs to overcome some challenges.

According to new research from JCDecaux UK, most people buying DOOH advertising programmatically (over three-quarters, or 77%, of UK pDOOH marketers) are always directly involved in planning or buying at least one other channel. That means most teams tasked with buying programmatic digital out-of-home (pDOOH) media today are not made up of dedicated OOH specialists but broader digital buyers who are now including DOOH in their programmatic planning mix.

While these findings indicate the increased accessibility of programmatic DOOH, they also hint at the growing need for integrated omnichannel teams to gain the OOH expertise required to incorporate pDOOH successfully and productively into their cross-channel planning.

We’ve compiled some resources to help you learn more about programmatic DOOH:

Programmatic DOOH is still relatively young, but it’s also an exciting playground for digital newcomers. Take it for a spin and see how it enhances your existing campaigns. You might be surprised by just how much it helps!

Groceryshop 2025: Why in-store screens are retail media’s last-mile goldmine

The message from Groceryshop 2025 was unmistakable: The initial era of retail media is closing, moving past what some called the “Gold Rush” phase. That phase, focused on high-margin, performance-driven e-commerce search, is no longer sufficient. The industry is entering what many are calling the “Age of Reckoning,” where true success requires a full-funnel approach and, critically, flawless execution at the point of purchase.

As brands allocate more budget to retail media, the emphasis is moving from digital shelf limitations to the hidden opportunities of the physical screen. Broadsign is key here: in-store screens serve as the final touchpoint where retailers can influence purchase decisions, create engaging shopping experiences, and unlock new revenue streams. 

The sense of urgency is confirmed by recent data from eMarketer, projecting that retail media ad spending will reach nearly $100 billion by 2029. That includes U.S. investment in in-store retail media, which is expected to surpass $1 billion by 2028, outpacing growth in online retail media. 

Why in-store media unlocks real value

In-store media uniquely combines mass reach, similar to connected TV audiences, with precision targeting at the moment of maximum intent.

Don’t mistake this for traditional out-of-home (OOH) advertising. Retail media requires a deeper integration of first-party data and sophisticated campaign management, extending to the point of purchase. Broadsign offers this core expertise, backed by twenty years of developing reliable, large-scale digital networks. This is where brand messaging turns into actionable insights, directly affecting shopper behaviour.

Strategically positioned digital screens, utilizing first-party data, are crucial for encouraging impulse buys at the last moment. They can showcase personalized offers and specific messages that enhance the in-store experience, influence last-minute decisions, and encourage shoppers to increase their cart sizes. This approach demonstrates how digital screens enhance the shopping experience and improve the average order value.

In a session, industry leaders such as Cristina Marinucci (Mondelez), Ali Miller (Instacart), and Sarah Marzano (eMarketer) highlighted that brand awareness isn’t solely built online. E-commerce has limitations; it lacks a digital counterpart to the disruptive, high-impact engagement offered by in-store screens. This presents an opportunity for brands and retailers to create meaningful and memorable moments that combine personalized experiences with a sense of community.

The hard work behind the magic: Collaboration and data harmony

Scaling in-store media is not simple. Execution is everything, and success requires solving multi-layered challenges.

  • Organizational alignment: Every team, from brand, trade, shopper marketing, and e-commerce, needs clarity on how to leverage the network. Without alignment, experimentation and innovation stall.
  • Data harmony: Flexible, real-time budget allocation depends on shared, integrated data systems. Clean-room partnerships are becoming increasingly essential for combining first-party data while respecting privacy, enabling both brands and retailers to maximize value.
  • Execution is everything: Retailers can no longer afford to simply track screen impressions. The next benchmark is true closed-loop attribution in-store, linking physical exposure directly to lift in sales and basket size. This is the critical question retailers must answer to justify long-term investment and prove performance to brand advertisers.

The retailers and networks that solve operational, measurement, and organizational challenges now will dominate the retail media landscape. The focus must be on getting in-store media right, because that’s where the last mile is won.

A question for retailers and brands

Are your current blockers operational, organizational, or data-related in nature? Understanding this will determine how effectively you can leverage in-store media to drive growth, engagement, and revenue.

Retail Media In-Store Report: 4 key insights shaping RMN strategies in 2025

For retailers seeking fresh revenue streams, the next big play isn’t online: it’s in-store. As digital inventory becomes saturated and competition intensifies, forward-thinking players are expanding their retail media networks (RMNs) into the physical environment — where most purchases still happen — connecting digital and in-store touchpoints to influence shoppers at the exact moment of decision.

To better understand this shift, the Retail Media: In-Store Report 2025, authored by leading retail media expert Colin Lewis and produced in collaboration with Broadsign, examines how in-store channels are evolving, the commercial models shaping their growth, and the measurement advances helping to prove ROI.

The four takeaways below highlight some of the biggest insights from the report — from market momentum and technology adoption to omnichannel integration and the maturation of measurement. Together, they illustrate why in-store is poised to become the next frontier of retail media.

Key takeaways for retailers:

Takeaway #1: In-store is the next growth frontier

While onsite and offsite channels still dominate retail media spend, in-store is fast emerging as the next growth driver. Globally, retail media is projected to reach $169.6 billion this year, surpassing TV ad revenue for the first time. Yet despite its relatively small share today, in-store retail media is on track to hit $1 billion by 2028 as retailers scale their digital capabilities and advertisers embrace the channel’s unique advantages.

Grocery chains may have pioneered the space, but they’re no longer alone. Today, other industries are developing their own retail media networks and using their physical presence to capitalize on this shift. With the right media capabilities and commercial strategy, the in-store opportunity stretches far beyond grocery to include sectors like petrol and convenience, shopping centres, hotels, and hospitality.

The appeal is clear: in-store combines mass reach in a high-attention environment with the ability to influence purchase decisions and drive real-time conversions at the shelf.

“In-store will begin to emerge as the new TV — a mass-reach advertising vehicle ideal for brands. Digital surfaces deliver what brands want and what linear TV has lost: fast reach, high attentiveness, younger audiences, and cultural relevance.”
— Andrew Lipsman, Media Ads and Commerce, Retail Media: In-Store Report 2025

For retailers, that makes in-store an invaluable extension of their RMN. By monetizing previously untapped foot traffic, they can unlock new revenue streams while strengthening omnichannel shopper engagement.

Takeaway #2: Screens and tech are redefining the store

At the heart of in-store retail media are digital screens — from large-format video walls to shelf-edge screens and point-of-purchase (POP) displays — delivering dynamic, data-driven campaigns right at the point of decision. These screens can adapt content based on time of day, weather, or even local shopping behaviours, helping brands capture attention and influence basket size in real time

But screens are just the start. Retailers are experimenting with other technologies that add depth and interactivity to the shopper journey, including:

  • Smart carts equipped with built-in displays
  • QR codes that connect signage, demos, or packaging to digital content, loyalty apps, or online campaigns
  • Interactive kiosks for product lookups, recipe ideas, or coupon printing
  • AI-powered shelves that trigger promotions when stock runs low
  • AR-enabled mirrors for virtual try-ons
  • Bluetooth beacons that send personalized offers to shoppers’ phones

Traditional formats will also continue to play a role. Print signage, product sampling, and in-store audio remain effective ways to reach shoppers, but they’re being reimagined with digital elements layered in. For example, dynamic QR codes on posters, demo carts, or packaging can link to apps, loyalty perks, or campaign landing pages — turning otherwise static interactions into measurable, omnichannel experiences.

Leading retailers are already proving what’s possible. Tesco’s “Scan as You Shop” handheld devices double as ad platforms powered by loyalty data. Meanwhile, Walmart is ramping up in-store advertising through its 170,000 digital screens, store-wide radio network, and new weekend sampling stations. Advertisers can pair demo tables with QR codes that drive shoppers to online options, recipes, or seasonal content, while bundling campaigns across screens, audio, and physical activations to maximize the impact at the point of sale.

Together, these innovations are transforming physical stores into full-fledged digital media environments — and giving retailers a scalable foundation to grow their retail media networks beyond the confines of ecommerce.

Takeaway #3: Omnichannel integration is key

In-store media doesn’t exist in a vacuum — its real power comes when it’s connected with onsite and offsite channels as part of a seamlessly integrated RMN. When campaigns carry through from a retailer’s website or app into the physical store, brands can maintain consistent messaging and attribution across the full shopper journey, from brand awareness to purchase conversion.

In-store plays a role at every stage of the funnel:

  • Awareness: Strategically placed signage, displays, and demos act as discovery tools, especially for impulse or unplanned purchases. 
  • Consideration: Interactive kiosks and QR codes surface reviews, ratings, and tutorials to help customers evaluate products. 
  • Conversion: Digital displays, shelf talkers, and personalized mobile app push notifications can close the deal by offering time-sensitive promotions, bundling offers, or reminders of loyalty benefits. 

Strategic integration makes these moments even more powerful. As consumers move fluidly between online browsing, mobile researching, and physical shopping, in-store media becomes a central node for narrative and experiential cohesion:

  • On-site integration: Link in-store media to shopper data from ecommerce sites, apps, and loyalty programs to bridge physical and digital experiences. Integration can also flow the other way, extending in-store inventory visibility into online ads — surfacing an “Available now in your local store!” message when browsing online — or using digital receipts to deliver post-purchase content, cross-sells, and offers.
  • Offsite integration: Connect in-store campaigns with offsite media like social, search, and CTV to drive store visits and purchases. Geotargeted programmatic ads can be timed with in-store launches, while influencer content and localized social ads guide shoppers into physical stores.

Real-world examples show how this works in practice. Tesco has piloted dynamic shelf-edge screens that adjust pricing and promotions in real time based on stock levels, time of day, or shopper profile. And Sephora has reimagined the beauty aisle with digital touchpoints that bring product reviews and tutorials into the store, most notably through its “Store of the Future” pilots in Asia, which blend interactive displays with personalized consultations to create a seamless digital-physical shopping experience.

Takeaway #4: Campaign measurement and commercial models are maturing

As retail media matures, advertisers expect the same accountability they’re used to from digital channels. It’s no longer enough to simply sell screen space — brands want evidence that in-store activations drive measurable results. For retailers, delivering credible, transparent measurement is essential to building trust and attracting repeat ad spend.

Industry-wide standards are starting to take shape. To bring more consistency and instill brands with greater confidence in directing marketing spend toward in-store campaigns, the Interactive Advertising Bureau (IAB) has introduced a set of standards that aim to provide unified definitions, measurement guidelines, and best practices for in-store retail media. While full standardization is still a work in progress, retailers don’t have to wait to start building credibility with advertisers.

While in-store retail media measurement is still developing, many best practices build on established digital out-of-home (DOOH) approaches. For a deeper dive into methodologies, see our guides on DOOH metrics, ROI measurement, and attribution.

At the same time, commercial models are evolving to meet different advertiser and campaign needs. In-store retail media is borrowing from digital and out-of-home playbooks but adapting them for the physical retail environment, where placements span digital screens, audio systems, shelf displays, and experiential zones. 

The choice of model shapes not only ROI for brands but also how retailers monetize their networks and structure long-term growth, with several common approaches taking shape:

  • CPM (cost per thousand impressions): Mirrors digital buying habits and works well for digital screens and audio, but relies on accurate impression tracking.
  • Tenancy or fixed placement: Predictable pricing for high-traffic placements or seasonal pushes, though less performance-driven.
  • Hybrid approaches: Blend fixed fees with added value like co-marketing, shopper insights, or data access.
  • Performance-based models: Tie costs directly to outcomes such as sales lift, with risk and reward shared between retailer and brand.
  • Sponsorships and experiential packages: High-impact brand-building plays, often tied to events or seasonal themes.

Each model suits different situations: new entrants may lean on performance-based or fixed-fee options to minimize risk, established CPGs often prefer tenancy or CPM for reliable visibility at scale, and premium or lifestyle brands may invest in sponsorships to build emotional resonance. However, the broader trend across the industry is toward hybrid models that pair fixed costs with measurable outcomes, supported by richer data and more sophisticated retail media networks.

Start building your in-store retail media strategy

In-store retail media may have trailed online in the past, but it’s catching up fast. With shoppers’ attention at its peak inside stores and new technologies making campaigns more measurable and scalable, the channel has quickly shifted from underutilized to essential. Put simply, if you haven’t invested in in-store solutions yet, you’re already falling behind.

For retailers, it’s a chance to unlock stronger RMN revenue growth while deepening omnichannel engagement. For brands, it’s an opportunity to reach consumers at the exact moment of purchase. And for the industry at large, it’s a sign that the future of retail media won’t just be online — it will be in-store.
