How effective are billboards as an advertising medium?

Short answer

Billboards are a cost-efficient brand awareness medium. Industry data shows an average ROI of $5.97 (per the widely cited OAAA/Benchmarketing analysis) per $1 spent on out of home advertising, CPMs of $1-$7 versus more than $15 for many digital platforms, and reach exceeding 90% of U.S. travelers in any given month.

Reach, recall, and ROI by the numbers

Billboards deliver broad, repeated exposure in ways that most digital formats cannot replicate. Outdoor ads reach more than 90% of U.S. travelers in a given month, and roughly 71% of people report awareness of billboard ads they have recently seen. Digital billboards perform especially well on recall: approximately 60% of viewers can remember a digital billboard within a month of exposure.

Cost efficiency is a consistent finding across the channel. The average ROI reported for out of home advertising is $5.97 for every $1 spent. CPMs for billboards typically fall between $1 and $7, compared with CPMs that often exceed $15 on many digital platforms. A single prime-location billboard can generate 50,000 to 100,000 views per day, which translates to roughly 1.4 to 2.8 million impressions over a four-week campaign.

What billboards cost and what drives pricing

Billboard costs vary with format, location, traffic volume, size, and campaign duration. Static billboards carry a one-time production and installation cost plus ongoing rental fees. Digital billboards tend to have higher rental rates but lower recurring production costs because there is no printing or physical installation for each creative rotation, and multiple creatives can share the same screen.

Monthly rental fees range from a few hundred dollars to several thousand dollars, with digital placements toward the higher end of that range. Design, production, and any agency fees add to the total. Longer-term contracts or multi-location buys can create room for negotiation. Compared with television, radio, and print, billboards provide continuous, location-specific exposure at relatively low CPMs, which is a meaningful advantage for campaigns that prioritize sustained visibility.

Advantages and limitations

What billboards do well:

• High reach and frequency, particularly in commuter corridors where the same audience passes repeatedly
• Always-on visibility, unlike digital placements that are served intermittently
• Physical presence means they cannot be blocked by ad filters or lost in a crowded feed
• Digital formats allow real-time content updates, dayparting, and multiple creative rotations in the same location
• Geographic placement enables targeting from hyper-local to broad national scale

Where billboards fall short:

• Audience segmentation is less granular than online platforms, though programmatic digital out of home is narrowing that gap
• Attribution is harder: connecting a billboard impression directly to a sale requires intentional tracking tools such as QR codes, unique URLs, or promo codes
• Creative constraints are real: messaging must be concise and visually immediate for viewers who may have only seconds of exposure
• Effectiveness depends heavily on securing the right high-traffic locations, which can be competitive and expensive
• Building brand awareness takes time; billboards are not well suited to campaigns expecting an immediate sales spike
• Local zoning rules and permitting can limit where digital displays are allowed

Making measurement work

The main measurement challenge with billboards is attribution. Common approaches include:

• Impression estimates built from traffic counts, dwell time, and mobile geolocation data
• Brand lift studies and recall surveys conducted after a campaign runs
• Direct-response tracking through QR codes, unique phone numbers, or promo codes embedded in the creative
• Monitoring changes in website traffic or sales during and after the campaign window
• Programmatic digital out of home platforms that provide real-time audience and performance data
• Combining billboard analytics with first-party CRM or sales data for a multi-touch attribution picture

For brand-building campaigns, recall studies and reach metrics are usually the primary indicators of success. For campaigns with a direct-response component, building a trackable mechanism into the creative from the start is essential.
