The Billboard Paradox
Expensive media placements are frequently compromised by inadequate execution.
A specific form of brand dysfunction escapes detection in positioning audits and media plan reviews. It appears on the side of a highway, above a stadium entrance, or on the back of a bus. The billboard is purchased at a premium, executed at minimum cost, and displayed where the disparity between investment and output is visible to all.
It is mostly a question of strategy, not design.
A brand that invests in a high-attention medium and delivers a low-effort message does not send a neutral signal. The result is worse than silence. The medium establishes an expectation. The execution fails to meet it. The brand makes its own mediocrity public.
The Execution Coefficient is a framework for diagnosing and correcting that mismatch: the ratio of media investment to creative investment, used as an audit tool across media.
Why OOH Makes the Problem Visible
Out-of-home advertising commands attention by design. The medium is large, static, and physically embedded in the places where people make decisions: commuting routes, retail corridors, event approaches. It does not rely on targeting algorithms or scroll behavior. It relies on presence.
The expense of maintaining that presence is considerable. Monthly billboard rates in a large market area can range from $10,000 to $25,000, or even higher. The cost to run a programmatic DOOH network across a whole metropolitan area for four weeks can reach the six-figure range. The companies that buy this kind of advertising space are, by definition, brands that have decided that attention is worth paying for.
However, the creative team does not always take that decision into account. For example, there is a stretched logo, the phone number, a tagline that has been on the market since 2014, and a stock photo showing hands shaking in front of a skyline.
The audience will spot the inconsistency even if they don't put it into words. A study conducted by The Harris Poll on behalf of OAAA in 2026 found that 69% of adults in the United States believe OOH advertising sounds more human than digital alternatives. While this perception is an advantage, it is only so when the way it is carried out merits it; the medium provides a stage, and the creative team performs.
The medium sets the stage, and the creative performs.
What the Data Shows About Creative Quality
The real-world implications of execution quality in out-of-home advertising are not based solely on individual examples. An analysis carried out in May 2026 by Clear Channel Outdoor and Super Optimal, using data from 27 RADARProof/Kantar studies, showed that in 70 percent of the campaigns examined, the quality of the creative was directly linked to the brand's results. Campaigns that had higher creative scores achieved a significantly greater level of brand lift. Those campaigns with lower creative scores were associated with poor performance in terms of ad awareness, favorability, and purchase intent.
The importance of that finding lies in the fact that it shows what is at stake. This is no mere matter of aesthetic opinion; poor creativity in a premium medium doesn't just reduce efficiency; it lowers the brand's standing, and the brand has actually spent money to create a negative impression.
An identical pattern can be observed in other media that receive significant attention. A study on web credibility conducted by Stanford's Persuasive Technology Lab found that 46.1% of users' credibility comments about websites specifically referenced design features such as layout, typography, and color. Visual presentation was the primary factor influencing initial trust judgments, even before the content was assessed.
The cognitive mechanism in question is well established. Reber, Schwarz, and Winkielman (2004) showed in their fundamental study on processing fluency that judgments of aesthetic value are not separate from judgments of trust. If an object is easy to process visually—that is, if it is clear, coherent and well composed—the brain interprets this ease as a positive signal; if the processing is effortful, fragmented or inconsistent, then the signal becomes negative. The physical size of the medium enhances both kinds of outcome.
Poor creative in a premium medium does not simply reduce efficiency. It degrades the brand's position.
The Execution Coefficient
The Execution Coefficient is a diagnostic ratio:
Execution Coefficient = Cost of Medium / Cost of Message
A high ratio signals a structural problem. A low ratio signals an opportunity.
The ratio is not a precise financial calculation. It is a forcing function. Placing the cost of the medium beside the cost of the creative makes the relationship explicit. The result is either strategically coherent or it is not.
A $15,000 per month billboard supported by a $500 Canva design produces an Execution Coefficient of 30:1. That ratio is not simply inefficient. It is diagnostic. It reveals how the organization regards its brand, what leadership believes the audience deserves, and whether marketing is managed as a strategic function or an operational task.
The coefficient varies by medium. The thresholds that define a healthy ratio differ for a billboard, a full-page print ad, a direct mail campaign, or a trade show booth. The forcing function remains: make the imbalance legible so it can be corrected.
Applying the Framework: A Medium Audit
When the Execution Coefficient is applied systematically across a brand's entire media portfolio, it serves as an audit tool with four steps.
STEP 1
Map every paid placement in market.
Make a list of all media placements the brand is currently underway with or has carried out over the past 12 months. This should include out-of-home (OOH), print, digital, broadcast, event, direct mail, and sponsorships. Also record the monthly or campaign cost for each.
STEP 2
Record the cost of the creative produced for each.
Make sure to include the design fees, production costs, photography, copywriting, and any other fees associated with agencies or vendors. Be specific: if the creative work was carried out in-house with no external expenses, give a realistic estimate of the time the people who carried it out spent. Even when time is not billed on an invoice, it still counts as a cost.
STEP 3
Calculate the ratio and flag the outliers.
Any placement with an Execution Coefficient greater than 10 to 1 must be examined; any placement with a ratio above 20 to 1 constitutes a structural problem. These thresholds are not absolute rules, since context matters, and a straightforward static OOH placement demands less creative effort than a full-bleed magazine spread. It is the ratios that bring about the discussion that should take place.
STEP 4
Choose the corrective option.
There are only two appropriate responses to a high Execution Coefficient. Invest more in creative or reduce placement spend. A brand that cannot afford to execute a premium medium well should not be in that medium. To remain in the placement with inadequate creative and hope it escapes notice compounds the damage.
A brand should not use a particular medium if it cannot effectively convey a premium approach in that medium.
What Good Execution Actually Looks Like
A low Execution Coefficient does not require lavish production. It requires proportionality—the standard shifts by medium.
For out-of-home, good execution is a single clear message, a visual that rewards attention without demanding it, and a composition that functions both in motion and at rest. The design does not need to be expensive. It needs to be considered.
For print, good execution is typography that reflects the brand's position rather than default system fonts, imagery that is specific rather than generic, and a layout that justifies its white space.
For digital, the same processing fluency dynamics apply. The standard is lower because the environment is noisier and attention is shorter. A banner ad assembled in 20 minutes for a high-attention digital channel sends the same signal as a poorly designed billboard: the brand does not believe its own placement is worth the effort.
Intentionality is the common denominator. Audiences do not consciously score execution quality. They register it. Processing fluency research is detailed: the ease or difficulty with which an audience processes a visual signal becomes a judgment about the source, the brand, not the ad.
The Organizational Question Behind the Ratio
It is rarely the case that a brand with a high Execution Coefficient suffers from a lack of awareness regarding the importance of design, since most marketing leaders do understand that design matters. The issue is structural: the media budget is allocated to one line item, while the creative budget is allocated to another, and the two budgets are never directly compared.
Media budgets are protected because they are tied to commitments: contracts, rate guarantees, campaign timelines. Creative budgets are cut because they appear discretionary. The result is an organization that honors its media commitments and breaks its brand promises.
The fix is structural. Creative and media budgets must be reviewed together, against the same standard. The Execution Coefficient provides a shared language for that conversation. It is not a financial metric. It is a strategic one. It makes the relationship between investment and quality explicit. Once that relationship is explicit, a ratio that cannot be defended becomes indefensible.
The organization keeps its commitments to the media and fulfills its brand promises.
The billboard is not the problem. The billboard is a mirror. It reflects whether the organization treats brand as a strategic asset or a line item. At speed, the answer is visible to all.
