The race to digitize out-of-home (OOH) is accelerating, with the global digital signage market expected to reach 75M connected displays this year, up from 68M in 2025. While many of these screens occupy familiar environments like office buildings, airports, and retail centers, others have appeared in less conventional spaces, such as sewer lids and restrooms.
Experimentation with new formats is picking up pace as advances in technology continue to lower market entry barriers. Meanwhile, the rise of commerce media networks is fueling a surge in new digital OOH (DOOH) inventory; at the same time, more publishers are converting static inventory to digital.
However, the rapid growth of digital inventory doesn’t automatically translate to stronger outcomes. Not every new screen translates to revenue, and inundating the market too quickly without prioritizing context and quality is risky. To this end, intentional DOOH inventory placement has never mattered more.
Not every screen is a strategy
In technology, innovations often draw criticism initially. Though met with doubt, Apple’s move to brick-and-mortar retail and Uber’s expansion into food delivery both paid off. These were intentional decisions driven by behavior, data, and a desire to improve the user experience.
The same logic applies to DOOH. Some of the highest performing inventory today once raised eyebrows, from digital panels at the pump to EV chargers and elevators. In the right context, unconventional placements can be highly effective, creating surprise, improving memorability, and driving brand lift.
Still, with the industry’s digital transformation intensifying, innovation is increasingly conflated with “available surface area.” Just because you can place a screen somewhere doesn’t mean you should. The most credible, high-performing screens are often placed with careful consideration given to the environment, audience mindset, and surrounding space. Strategic, intentional screen placement is essential to ensuring optimal campaign performance that aligns with buyer expectations.
The costs of miscalculating screen placements
Sightline obstructions, environmental clutter, and low dwell times can lessen a screen’s impact. So can the wrong lighting, glare, or traffic flow. Though none of these are catastrophic on a micro level, they can diminish campaign performance on a macro scale. And when campaigns underperform, the channel, not the creative, often shoulders the blame.
Brands and agencies evaluate post-campaign performance and compare notes, with procurement teams often the first to scrutinize value. If inventory placement consistently feels off, industry skepticism is inevitable, which could lead to more rigid measurement demands and increased pressure on CPMs. It may also prompt publishers to pull back from testing innovative new formats and buyers to shift budgets to other channels.
Agency and buyer trust is earned over time, and if lost, can be costly to rebuild. For such a credible medium like DOOH, the stakes are high. Protecting its reputation requires a commitment to intentional screen deployment, especially as digitization accelerates. Curation is key.
Curation considerations
Whether you’re a legacy media owner or an independent operator just getting into the business, avoid falling into a monetization trap by not saying yes to every screen. Meaningful deployments require careful planning and thought to attention, dwell time, reach, and context.
Research suggests ads that capture views for 2.5 seconds or longer increase the odds of recall, making high-attention environments, like bus shelters, restaurants, gyms, cinemas, and shopping centers, optimal choices. Dwell time is also a factor. DOOH ads in high dwell-time environments not only make an impression but also inspire action. An airport study found 83% of frequent flyers noticed airport ads, and 75% took action after seeing one.
But that doesn’t mean there isn’t value in DOOH formats with shorter dwell times. Highway billboards offer incredible visibility and reach. Appealing to advertisers often means deploying a combination of placements that cater to both. Context also matters. It’s crucial to survey your OOH placement locations in advance to ensure they’re not near facilities that brands might see as controversial, like a place of worship, schools, protected areas, or spots consumers might see as invasive.
The bottom line
More ad spend is shifting to DOOH as ad fraud and screen fatigue erode confidence in other digital channels, and as programmatic DOOH and dynamic creative optimization mature. DOOH has earned its rightful place as a core line item in modern media plans, and with that status comes pressure to scale.
However, the industry cannot sacrifice growth at the expense of quality. We must continue to encourage innovation and test new formats, but intention must drive every DOOH deployment decision. The operators who understand that will do more than build trust with buyers; they’ll help to shape the future of the medium.
