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.

Jump ahead to:

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 via the Broadsign Ads DSP 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 Ads DSP, 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!

How 75Media increased its fill rates by 15% with the Broadsign Platform

2024 was a record-breaking year for out-of-home (OOH) advertising in the United Kingdom (UK). Total OOH revenue for the region grew 7.7%, pulling in a record-breaking £1.4 billion in revenue. While spend is expected to cool down slightly in 2025 at 7.2%, the medium will grow through technological innovations like dynamic digital billboards, interactive displays, and programmatic advertising. 

Digital OOH (DOOH) now dominates the OOH landscape, accounting for 67.1% of total spend as brands seek the flexibility and creativity that digital offers. That being said, demand for static OOH – also known as classic OOH–  isn’t going anywhere, remaining an effective medium for long-term brand-building campaigns. 

With both formats offering distinct benefits to advertisers, the most effective campaigns combine both. This is where UK-based media owner 75Media comes in. As one of the leading providers of large-format static and digital roadside billboards in the region, 75Media makes it easy for brands, big and small, to tap into the power of OOH with the flexibility, scale and simplicity that modern advertisers need today.

How 75Media makes out-of-home simple for buyers

Wanting to provide brands with national reach through large-format, high-impact roadside billboards, 75Media’s sites are strategically positioned in high-traffic locations across the UK. These include key commuter routes and busy city centres, with placements carefully chosen for their proximity to gyms, shopping centres, supermarkets, and other points of interest. 

Through a series of strategic acquisitions, 75Media has exponentially grown its network, going from 140 to nearly 1,300 digital and static billboards across the UK in just five years. Today, with just over 1,000 large-format static billboards, 75Media’s hybrid network is about 75% static and 25% digital. 

In addition to their wide-reaching network, advertisers choose 75Media’s network because they make OOH measurable and efficient without compromising on quality. Wanting to deliver real audiences to clients as quickly as possible, 75Media focuses on minimizing the back-and-forth typically needed to book OOH campaigns. 

75Media’s network attracts a broad mix of advertisers and campaigns, including major brand campaigns, fast-moving consumer goods promotions, as well as ads for local businesses, the public sector and charitable organizations. On the digital side of its network, there’s exciting momentum toward dynamic creative optimization (DCO) campaigns. Collaborating with their data partners, DOOH.com, Veridooh and Artbot, 75Media has been unlocking new ways for brands to engage with their audiences in real-time. 

One notable dynamic, data-driven campaign that ran on 75Media’s network was Nike’s campaign featuring renowned Norwegian professional footballer Erling Haaland for the promotion of its new Mercurial football shoe. Leveraging the dynamic triggers available on the Broadsign Platform, the artwork and messaging of the DOOH ad would dynamically update whenever Haaland scored a goal during a match. 

How Broadsign makes it easy for 75Media to run its network

One platform to efficiently scale, manage, and sell their digital and static out-of-home inventory

75Media has been using the Broadsign Platform since day one. Operations Director Alex Simpson—one of 75Media’s founding directors—had previously used Broadsign at his former company and saw first hand how reliable and effective the platform was. So when 75Media launched in 2020, continuing that partnership was a natural choice. And with their significant growth plans, they needed a platform that was capable of seamlessly scaling alongside their business. 

In addition to the platform’s robustness and reliability, 75Media chose Broadsign for its content and network management capabilities. The manual work typically tied to campaign scheduling, booking and execution is now automated, freeing up the team’s time to focus on enhancing advertisers’ experience with OOH.

Moreover, managing their static and digital assets through the Broadsign Platform not only kept things efficient and organized, but also provided them with seamless workflows to plan, execute, and monitor static and digital OOH campaigns without unnecessary complications. 

“The reporting capabilities provided by the Broadsign Platform for our digital and static assets allow us to be totally transparent with our clients. Being able to show brands exactly how their campaigns are performing in-flight is invaluable.”

Alex Simpson, Operations Director, 75Media

How 75Media optimizes fill rates with Broadsign’s flexible campaigns

Another key capability that 75Media has been leveraging is Broadsign’s flexible selling tools for their DOOH campaigns. This gives them access to our flexible campaign types, which are goal-based and data-triggered, allowing you to deliver more targeted results. In fact, 80% of DOOH campaigns that ran on 75Media’s network in 2024 leveraged flexible campaigns.

The most widely used flexible campaign type was the Campaign Average Share of Voice (SoV). This allows advertisers to define the average percentage of screen time their ad should get over the campaign’s duration. So what makes it flexible? The SoV on each screen can vary day-to-day to accommodate other campaigns requiring the same screens, but the target average SoV across all screens over the campaign’s duration will always be met. 

This is made possible by Broadsign’s rebalancing feature, which leverages our optimization engine to modify the pace at which a campaign is delivered to guarantee targets are met. Since adopting these new flexible capabilities, 75Media has seen an increase of 15% in its screen fill rates and has strengthened its client relationships by offering more flexible solutions. 

“Broadsign’s rebalancing feature helps deliver our campaigns efficiently while allowing us to maximize the space across our inventory. It’s particularly useful in ensuring everything runs smoothly without daily intervention from our delivery team.”

Alex Simpson, Operations Director, 75Media

The Campaign Average SoV campaign type is particularly useful for markets where flexible buying has not been widely adopted. Buyers can maintain the same fixed results typically obtained through slot-based campaigns while providing you with the operational flexibility to fill your network optimally.

What we can expect from 75Media in the near future

While 75Media will continue to invest in new digital and static sites to extend its coverage and reach, its focus in the near future is to become the most efficient OOH operator in the market. It plans to do this by investing in new technology and automation, removing the medium’s preconceived pain points, and providing the quickest way to buy OOH. 

Additionally, as programmatic capabilities continue to evolve, advertisers will grow more confident in data-driven OOH. With demand expected to rise, 75Media is actively exploring new audience analytics and multiple data integrations to enhance targeting and boost campaign effectiveness.

Revolutionizing Broadsign’s Programmatic SSP: AI creative assistance and extended brand safety

According to GroupM’s 2024 End-of-Year Global Advertising Forecast, digital out-of-home (DOOH) advertising is projected to account for 42% of total out-of-home (OOH) ad revenue by the end of this year. One key factor of growth for DOOH is the integration of programmatic technology, allowing for real-time bidding and dynamic content delivery, enhancing targeting capabilities and operational efficiency. 

As programmatic DOOH (pDOOH) only continues to grow in importance, we’re excited to unveil groundbreaking enhancements to Broadsign’s programmatic Supply-Side Platform (SSP), designed to modernize workflows, maximize revenue, and reinforce brand safety for our media owners. The introduction of our patent-pending AI Assistant, Broadsign Header Bidder Pro, and enhanced Competitive Separation features, is going to revolutionize the way you sell, manage and deliver programmatic DOOH campaigns.

Your AI Assistant has arrived

Unveiled at our annual customer summit, Broadsign Connect, in Barcelona, Spain, back in January, Broadsign’s AI Assistant is a patent-pending tool designed to reduce the time media owners spend on repetitive tasks. This includes reviewing, categorizing, and approving incoming ad creatives from programmatic bids sent through demand-side platforms (DSPs). 

In 2024 alone, Broadsign media owners received between 32,000 to 43,000 unique OOH creatives each month that need to be manually reviewed and categorized. With that number expected to double this year, Broadsign’s AI Assistant will provide significant time and cost savings. As ad creatives are submitted to the Broadsign SSP, the AI Assistant sends an automated email with category and approval suggestions. 

To ensure that it integrates seamlessly with your current review and categorization process, Broadsign’s AI Assistant learns your network’s unique categories to organize and review creatives. It will continue to learn and evolve over time, and you get to decide whether to use the AI Assistant to fully automate the process or to continue providing recommendations only. 

By automating the categorization process, Broadsign’s AI Assistant can minimize common misclassification errors and quickly identify sensitive content that could hinder brand safety efforts. For instance, ads featuring alcohol on a screen near a school, or an ad that violates local laws like displaying a political ad next to a polling location, would be flagged by the AI Assistant with recommendations to reject the creative.

Priced-based auctions are now available with Header Bidder Pro

As part of the evolution of our Header Bidder offering, we’re excited to introduce the Broadsign Header Bidder Pro. As a refresher, we introduced our Header Bidder in 2022, which consolidates demand from multiple supply-side partners. This one-to-many programmatic approach allows media owners to simplify ad operations, maximize yield value, and increase fill rates. 

With Broadsign’s Header Bidder Pro, you now have the ability to run price-based auctions, helping you get the most out of your programmatic campaigns through higher yields and fill rates, not to mention a simplified auction process. A key advantage of header bidding, or mediation layers, is the ability to consolidate your programmatic demand into one slot, freeing up valuable space on your network. You also get access to better content controls, creative caching, and synchronization capabilities that aren’t possible with container-based setups. 

The combined benefits of Broadsign’s AI Assistant with Header Bidder Pro

As Broadsign’s AI creative assistant can categorize creatives more accurately, Broadsign’s header bidding solution will be able to easily match the right inventory with the right demand, resulting in higher-quality ad placements, improved buying satisfaction, and increased competition for premium inventory. Moreover, the combined features will facilitate the alignment of creatives with the varying compliance requirements across demand sources. 

Enhanced brand safety for programmatic out-of-home campaigns

Broadsign media owners have long been able to set competitive separation criteria for directly sold campaigns. With this release, we’re excited to extend that capability to programmatic campaigns. More specifically, categories created in the Broadsign CMS will now sync with Broadsign programmatic and platform interfaces. 

So, how does it work? Let’s say you have two fast food restaurants, neither of which want their ad to play next to each other. If these campaigns are booked directly, you can easily separate the campaigns with the existing capabilities mentioned above. However, if one – or both – campaigns were booked programmatically, there would have been no way to guarantee that the programmatic slot would not play next to the directly booked slot. 

With Competitive Separation for programmatic campaigns, that’s no longer the case. The system will make every effort to prevent these two campaigns from playing one after another, regardless of channel: directly sold or programmatic. However, It’s important to note that competitive separation is only available for other SSP creatives if you are running Header Bidder Pro.

The combined benefits of Broadsign’s AI Assistant with competitive separation

With Broadsign’s AI Assistant, creatives can be categorized at a more granular level, identifying not just the brand but also its competitors and associated categories. The AI Assistant will also be learning directly from your existing categories and can apply your custom taxonomy onto your creatives, saving you time when approving creatives and automating the competitive separation process from programmatic back into your player. 

It can also adapt and learn over time, recognizing nuanced relationships between brands and subcategories, such as differentiating between an “energy drink” and a “soft drink.” Moreover, as the AI creative assistant can enforce these competitive separation rules more effectively, advertisers will perceive your network as the more reliable option when it comes to protecting brand visibility and exclusivity.

How these enhancements will help you stay ahead in the rapidly evolving programmatic landscape

While these features were designed to solve a specific pain point at different steps of the pDOOH workflow, the real value comes from having these features work hand-in-hand for more efficient programmatic workflows, reduced errors, and to future-proof your programmatic revenue. 

Broadsign’s AI assistant helps automate time-consuming tasks like categorizing creatives and identifying competing ads, allowing for faster decision-making within header bidding frameworks. Combine that with competitive separation, and you can guarantee strategic and compliant ad placements to advertisers. 

Furthermore, failure to ensure competitive separation or effective creative categorization can lead to possible compliance violations, rejected bids, or damaged buyer relationships. Having all three features work together simultaneously can help minimize errors, ensuring a smooth and compliant workflow. 

Finally, integrating these features into how you sell and manage pDOOH campaigns ensures that you stay ahead of the competition in today’s rapidly evolving programmatic landscape. Combining AI-powered categorization, header bidding, and competitive separation creates a robust ecosystem that drives revenue, enhances buyer trust, and delivers a superior user experience – all while operating at scale and with greater efficiency.

Why travel marketers are turning to OOH for scalable reach and ROI

Tourism is thriving once again, and brands are racing to capture the attention of today’s travellers. As the industry continues to rebound and evolve from its pandemic dip, marketers are rethinking how to connect with multiple generations at key moments in the travel journey. Out-of-home (OOH) advertising remains a powerful, performance-driven medium, valued not only for its visual impact but also for its ability to deliver cost efficiency and broad market penetration across both global and local campaigns. 

For travel marketers, OOH offers strategic ways to engage audiences in real time. From digital billboards near airports to transit ads and dynamic creative triggered by weather or location, the channel excels at reaching travellers on the move or those dreaming of their next escape.

With its focus on visual storytelling and contextual relevance, OOH is especially effective at sparking wanderlust, promoting destinations, and influencing travel decisions. High-dwell environments like airports, transit hubs, and city centres offer premium visibility where plans are being made, driving strong recall and engagement.

Travel marketers are doubling down on OOH: Here’s why

Out-of-home has become one of the fastest-growing channels for travel and tourism marketers. According to Broadsign data, travel’s share of OOH ad spend rose from 3.8% in 2023 to 5.7% in 2024, reaching 8% in early 2025—making it the top vertical for OOH spend so far this year.

According to the Out of Home Advertising Association of America (OAAA), major travel brands like Hotels.com, Expedia, and VRBO ranked among the top OOH advertisers in 2024. This surge in activity is being fueled by several key factors: growing demand for both domestic and international travel, renewed airline operations, and increased marketing investments from hotels, online travel agencies, and tourism boards eager to capture consumer attention.

Maximizing efficiency and reach: The dollar value of OOH

At a time when marketers are being asked to do more with less, OOH is proving to be one of the most efficient and effective channels for driving reach and results. For travel brands, it offers a rare mix of broad exposure, cost control, and message adaptability, making it a smart choice when performance and efficiency are under the microscope.

This efficiency is especially evident when comparing OOH to other media channels. The medium delivers high-impact visibility at a significantly lower cost per thousand impressions (CPM) than connected TV (CTV), paid social, or display. According to Solomon Partners and the World Out of Home Organization (WOO), OOH consistently offers a lower cost per impression, with average CPMs ranging from $2 to $9 USD, well below most digital formats. That makes it one of the most cost-effective ways to achieve mass reach, particularly in high-traffic, high-dwell time environments like airports, transit hubs, and city centres. 

But cost efficiency doesn’t mean sacrificing performance. In fact, research from the OAAA and Comscore found that OOH drives online activation rates 5 to 6 times higher than expected, outperforming channels like TV, video, radio, banner ads, and print when it comes to driving digital engagement. 

Even in a softening economy, travel marketers are maintaining or increasing their OOH investment, driven by sustained consumer demand for experiences and exploration. Domestic travel is gaining particular momentum—U.S. hotels and resorts ranked among the top 10 OOH product categories in 2024, accounting for 3% of total year-end spend. Tourism boards and airlines are also increasingly anchoring their media strategies in OOH, using it as the lead channel in integrated campaigns that blend broad awareness with measurable results.

At the same time, multi-city and international campaigns are scaling efficiently, allowing brands to build awareness across key markets while tailoring creative to specific audiences. Marketers can keep messaging consistent across regions while adapting visuals or calls to action for different cities or traveller segments—an essential advantage when engaging both global tourists and local visitors. 

Finally, timing remains critical. Launching OOH campaigns ahead of peak travel windows or booking periods allows brands to influence decisions early in the planning journey. Many consumers start researching destinations weeks or months in advance, so a strong OOH presence during this window keeps your brand top of mind. Aligning campaigns with seasonal trends, long weekends, school breaks, or major events can further maximize reach and impact.

Measuring OOH’s real-world impact

For years, one of the biggest challenges in out-of-home advertising was proving its value beyond brand awareness. But that’s changing quickly. With the rise of advanced measurement tools and location intelligence platforms, travel marketers now have access to real-world insights that directly connect ad exposure to consumer behaviour.

Platforms like Arrivalist are leading this shift, offering new visibility into traveller movement and enabling marketers to understand how OOH influences actions like visits, overnight stays, and the path to purchase. By matching mobile advertising IDs (MAIDs) to campaign exposure, tourism boards can measure visitation uplift and identify which audiences are most likely to act after seeing an OOH ad.

These insights go far beyond impressions, helping quantify tangible outcomes, like increased foot traffic to cities, attractions, hotels, or short-term rentals following a campaign. Marketers can also layer campaign data with flight, hotel, or rental trends to better understand travel intent and booking behaviour.

This level of attribution is especially valuable for tourism boards, which often need to justify public or partner funding by demonstrating a clear return on investment. As DOOH adoption grows, more campaigns are integrating measurement from the outset, enabling smarter optimizations and more transparent performance benchmarks throughout the campaign lifecycle.

Scaling smart with programmatic DOOH

Many of today’s travel campaigns span multiple markets, and programmatic DOOH (pDOOH) is helping power that growth. It gives brands the speed, agility, and precision needed to launch quickly, adapt mid-flight, and respond in real time to performance data. Unlike traditional media, programmatic buying eliminates long lead times, allowing marketers to shift budgets, swap creative, or refine targeting based on changing market conditions or traveller behaviour—all while retaining the bold, visual impact OOH is known for.

Dynamic Creative Optimization (DCO) adds another layer of relevance by tailoring content in real time based on data like location, weather, language, or time of day. For travel marketers, this enables region-specific offers, weather-based messaging, and event tie-ins that drive stronger engagement.

Programmatic tools also streamline cross-market execution, enabling consistent messaging across regions while customizing creative for local audiences. This makes them especially valuable for multi-city and global tourism campaigns.

Out-of-home is no longer just a top-of-funnel awareness tool—it’s a performance-driven, scalable, and data-rich channel built for modern travel marketing. Whether you’re launching a global tourism campaign or targeting specific markets with dynamic, real-time creative, OOH delivers the reach, efficiency, and impact needed to move travellers from inspiration to action.
