Digital ads get skipped. Billboards get ignored. But closed-loop environments deliver something different.

Here’s a stat that should get your attention:

Out-of-home advertising delivers 84-86% consumer ad recall.

That’s according to Solomon Partners’ 2025 analysis of advertising effectiveness across major media channels. To put it in perspective: online ads achieve 46-57% recall. Streaming TV hovers in a similar range. OOH nearly doubles both.

In a world of ad blockers, subscription services, and infinite scroll, physical advertising is experiencing a renaissance. And parking structures represent some of the most undervalued OOH inventory available.

Why OOH Is Outperforming Digital

The resurgence of out-of-home advertising isn’t accidental. Several structural factors are driving the shift:

• Ad blocking: Roughly 40% of internet users employ ad blockers. You can’t block a billboard.
• Subscription fatigue: Consumers increasingly pay to avoid ads on streaming platforms. Physical environments don’t offer that option.
• Cookie deprecation: As digital tracking becomes more restricted, the deterministic audiences available through physical locations become more valuable.
• Attention scarcity: Digital ads compete with infinite content. Physical ads exist in environments where attention is already allocated to navigation and awareness.

A five-year study by Kantar found that OOH delivers a 13.3% increase in ad awareness compared to digital media, TV, and connected TV. The research showed OOH consistently outperforms digital channels across brand favorability and purchase intent as well.

MAGNA projects OOH as the fastest-growing legacy medium in 2025, with digital out-of-home (DOOH) leading the charge at approximately 12% growth.

The Closed-Loop Advantage

Not all OOH is created equal. A highway billboard gets a fraction of a second of attention from drivers focused on the road. A transit ad competes with phones and fellow passengers for attention.

Parking structures offer something different: a closed-loop environment with guaranteed, repeated exposure.

Consider the visitor journey. A driver enters the garage, navigating slowly while looking for a spot. They pass columns multiple times while parking. They walk past columns to reach the elevator. Hours later, they reverse the journey walking back, finding their car, driving out.

A European eye-tracking study measured this precisely. Using VR headsets with eye-tracking technology, researchers found that 100% of participants noticed advertisements on column wraps. Each driver viewed the ads an average of 17 times during a single visit.

That’s not comparable to a billboard glimpsed at 65 mph. It’s sustained, repeated exposure in an environment where visitors are already in navigation mode, actively scanning their surroundings.

The CPM Advantage

Beyond effectiveness, OOH offers cost efficiency that surprises many advertisers.

Solomon Partners’ analysis found that OOH delivers the lowest CPMs (cost per thousand impressions) across major media channels. When you combine best-in-class recall rates with lowest-in-class costs, the ROI equation becomes compelling.

For property owners, this means advertisers are willing to pay meaningful rates for parking structure placements — especially when you can demonstrate the captive audience, repeat exposure, and high-intent visitor demographics.

What Advertisers Want

Brands evaluating OOH placements look for several characteristics:

• Guaranteed visibility: No ad blockers, no skip buttons, no algorithm deciding whether to show the ad
• Audience quality: High-income, high-intent visitors — people actively engaged in shopping, travel, healthcare, or hospitality
• Frequency: Multiple exposures per visit, building recall and brand familiarity
• Context: Relevant environments where the brand message aligns with visitor mindset

Parking structures at premium properties check every box. A luxury mall garage delivers affluent shoppers. A hospital garage reaches healthcare decision-makers. An airport garage captures business travelers. A hotel garage provides visitors in spending mode.

The Untapped Inventory

Here’s the opportunity: most parking structures haven’t recognized what they’re sitting on.

While retail media networks are valued in the hundreds of billions, physical retail media (including parking) captures less than 1% of that spend. The inventory exists; it simply hasn’t been activated.

Property owners who move first can capture advertiser relationships and establish rate cards before the market matures. The same columns that currently display nothing, or faded wayfinding from a decade ago, represent premium inventory that brands will pay to access.

The Bottom Line

Digital advertising is getting harder. Ad blockers, privacy restrictions, and subscription services are eroding reach and effectiveness. Meanwhile, physical advertising in controlled environments is delivering recall rates that digital can’t match.

Your parking structure is OOH inventory you already own. Every column is a potential placement. Every visitor represents impressions you’re currently giving away.

The question isn’t whether this opportunity exists  the data is clear. The question is whether you’ll capture it before your competitors do.
