- There are two ROI models: An on-premise business sign is evaluated differently from a billboard that earns revenue by selling advertising.
- Published benchmarks need context: Research supports the business value of effective signage and OOH advertising, but no percentage applies to every location or display.
- Payback must be calculated: Use attributable gross profit, avoided changeout costs, and operating expenses instead of assuming a guaranteed timeline.
LED digital signage can deliver stronger long-term advertising value than traditional signage when a business benefits from greater visibility, multiple promotions, and remote content updates. Traditional signs usually cost less initially, while LED screens provide more ways to change messages and use the same sign for different campaigns over time.
The better ROI depends on the business, location, traffic, content quality, operating costs, and ability to measure results. Additional sales and avoided print or changeout expenses can help offset the initial LED investment, but no installer can responsibly guarantee a specific return.
Two Different Outdoor LED Display ROI Models
On-Premise Business Signs
Retailers, restaurants, auto dealers, churches, and other organizations use an electronic message center to promote the business located on the property. ROI comes from attributable sales, inquiries, visits, and avoided print or sign-change costs.
Third-Party DOOH Advertising
Billboard and media operators sell advertising inventory to outside brands. ROI comes from occupancy, impression delivery, advertising rates, operating expenses, and campaign performance.
LED Screen vs. Traditional Signage
| Consideration | Traditional Signage | LED Digital Signage |
|---|---|---|
| Initial cost | Generally lower | Generally higher |
| Content changes | New print, face, or service visit may be required | Digital updates without replacing the sign face |
| Multiple promotions | Usually one primary message | Multiple scheduled messages |
| Visibility | Depends on illumination and design | High-brightness, attention-getting content |
| Remote management | Not normally available | Cloud or network-based updates |
| Moving content | Not available | Possible where appropriate and permitted |
Verified Benchmarks for On-Premise Signage
Sign Research Foundation findings provide useful planning context for signage generally. They do not establish a guaranteed return for every outdoor LED display.
Weekly sales increase
A documented business experienced a 16% increase in weekly sales after targeted changes to its exterior signage.
Businesses reporting gains
Sixty percent of surveyed businesses reported average sales increases of 10% or more after adding or updating signs.
New-store visits
Thirty-six percent of consumers reported visiting a new store because of the quality of its signage.
Source and scope: Sign Research Foundation research summary . These figures address exterior or on-premise signage more broadly and should not be represented as LED-screen-specific guarantees.
What Research Says About Promoted Products
A 2026 Journal of Marketing field study covering 237 campaigns and approximately 30 million shoppers found that exposure to in-store digital signage increased the likelihood of purchasing featured products by 8.1%. This is evidence for in-store digital signage, not a guaranteed sales increase for an outdoor LED sign. Read the published study .
Verified OOH and DOOH Advertising Benchmarks
Third-party billboard campaigns use a different ROI framework from an on-premise business sign. The following OAAA figures describe the broader out-of-home advertising channel.
Revenue per advertising dollar
OAAA cites a Benchmarketing analysis estimating an average $5.97 in revenue for each dollar spent on OOH advertising.
Notice OOH advertising
An OAAA and Morning Consult survey found that 88% of adults notice OOH advertisements.
Engaged after noticing
Among consumers who noticed OOH ads, 78% reported a recent form of engagement.
The same OAAA and Morning Consult survey reported that 76% used a mobile device to learn more about a featured product, 51% searched for more information about an advertiser, and 43% made an online purchase. These are survey results across OOH formats, not guaranteed outcomes for a particular screen.
Separately, an OAAA analysis of 45 attribution case studies reported lifts of 50% to 127% in store visitation, 6% to 20% in purchase consideration, 10% to 35% in purchase intent, and as much as 13% to 66% in ad recall among consumers exposed to the campaigns. These are campaign-level lift ranges relative to comparison groups, not universal business revenue increases.

Why There Is No Universal Payback Period
A 9-month, 12-month, or 18-month payback claim cannot be applied responsibly without knowing the business’s sales volume, gross margin, attributable lift, installed cost, financing, energy use, maintenance, and content-management expenses. Revenue lift alone is not the same as profit.
How to Calculate Your Own ROI
Monthly net benefit = attributable incremental gross profit + avoided sign-change costs − monthly operating costs
Estimated payback period = total installed investment ÷ monthly net benefit
Start with a conservative baseline and track specific calls to action, offer redemptions, web visits, inquiries, store visits, or sales during defined campaigns. Evaluate gross profit rather than revenue alone, and compare the results against the same location and season whenever possible.
