In an age dominated by digital advertising, where businesses obsess over clicks, impressions, and algorithms, outdoor billboards can seem like a relic of the past. Yet, as you drive along the highway, walk through a bustling city, or ride public transportation, billboards remain a constant—looming large and impossible to ignore.
So, are they still worth the investment in 2025? The answer depends on how you measure impact. When evaluated through a data-driven lens, outdoor billboards reveal surprising staying power—and even advantages—over some digital channels.
The Evolution of Billboard Advertising
Traditional billboards date back over a century, but the medium has evolved dramatically. Today’s advertisers have options ranging from static paper or vinyl boards to sleek digital displays that rotate multiple ads, adjust messaging in real-time, and even interact with consumers via mobile integrations.
This evolution has been critical in keeping the format relevant. The Outdoor Advertising Association of America (OAAA) reports that out-of-home (OOH) advertising—including billboards—is now the fastest-growing traditional ad medium, outpacing TV, radio, and print.
With so many options available, advertisers now use billboards more strategically, often as part of broader omnichannel campaigns. But what do the numbers say?
Reach, Frequency, and Cost Effectiveness
One of the most compelling arguments for billboard advertising lies in its reach. Unlike digital ads that can be skipped, blocked, or lost in a scroll, billboards are inherently viewable—24/7.
According to a Nielsen study, 66% of travelers report noticing a billboard in the past week, and 42% say they’ve taken some kind of action—such as visiting a website, searching for a product, or discussing the ad with others. That kind of engagement rivals, and in some cases surpasses, digital click-through rates.
Cost-wise, billboards offer a competitive edge. The industry measures effectiveness using CPM (cost per thousand impressions). For billboards, CPM typically ranges from $3 to $8, depending on location and format. Compare that to the average CPM for Facebook ($7–$10) or Google Ads ($2–$4 for search, often higher for display), and billboards begin to look more economical—especially when brand visibility and local impact are priorities.
Digital Billboards and Real-Time Optimization
The rise of digital billboards has added a dynamic layer to the medium. Advertisers can now rotate messages throughout the day, customize content based on weather, time, or events, and even respond to news or social media trends in real-time.
For instance, a restaurant could promote breakfast specials in the morning and switch to dinner promos by 5 p.m.—all on the same screen. Some campaigns have even used real-time traffic or sports scores to tailor messages, increasing relevance and engagement.
This flexibility makes digital billboards especially attractive for advertisers seeking both reach and responsiveness. While the upfront costs may be higher than traditional boards, the ability to run multiple campaigns on a single board—and change messaging without printing new material—can increase ROI over time.
Brand Building and Local Presence
One area where billboards excel is brand awareness. Unlike digital formats that are highly targeted but fleeting, billboards offer repeated exposure. People commuting to work or passing a location daily see the same billboard over and over, reinforcing the message.
This frequency builds mental availability—a key driver of brand recall and consumer choice, according to marketing theorist Byron Sharp. If your brand is top-of-mind when a buying decision arises, you’ve already won half the battle.
Additionally, billboards help solidify a local presence. For businesses operating in specific regions or cities, outdoor ads signal that they’re part of the community. A national campaign might feel distant, but a billboard near your home, favorite coffee shop, or gym is hard to ignore—and even harder to forget.
Measuring Impact: The Data Behind the Decision
One of the historical criticisms of billboard advertising has been its lack of measurability. Unlike digital channels, you can’t easily track who viewed a sign or whether they acted on it.
But that’s changing.
Technologies like mobile geofencing, footfall tracking, and QR codes now offer better attribution. Advertisers can measure how many people passed a billboard, how long they were nearby, and whether they later visited a store or scanned a code. For example:
- A 2022 study by Posterscope and Clear Channel found that OOH ads increased mobile click-through rates by 15% when used in tandem with digital ads.
- Brands that added billboard campaigns to their media mix reported a 20–30% lift in search activity, particularly when tied to high-traffic areas.
In other words, while billboards don’t offer click data directly, they amplify the effectiveness of other channels—a phenomenon known as cross-channel synergy.
When Billboards Make Sense (and When They Don’t)
Despite their benefits, billboards aren’t for everyone or every goal.
They’re best suited for:
- Brand awareness campaigns
- Product launches or event promotions
- Geographically targeted efforts (like local businesses or political ads)
- Reinforcing digital or TV campaigns
However, if your campaign hinges on precise audience targeting, rapid A/B testing, or detailed user behavior analytics, digital channels will likely offer better control. Billboards are a broad-brush medium—you can’t segment by age, gender, or interest like you can online.
And of course, location matters. A prime billboard in a bustling city can deliver immense value, while a poorly placed one in a low-traffic area might be a waste of budget.
Final Verdict: Are They Worth It?
The question isn’t whether billboards are better than digital or traditional channels—it’s whether they play the right role in your strategy.
When used correctly, billboards punch above their weight, delivering high visibility, strong local impact, and surprisingly efficient CPMs. They can elevate a brand, drive real-world engagement, and complement other forms of advertising in powerful ways.
In a media environment full of noise and fragmentation, the simplicity and presence of a billboard can actually be its greatest strength. So yes—when backed by data, aligned with your goals, and creatively executed—outdoor billboards are absolutely worth the investment.
