ROI of Billboards
Key Takeaways
Billboard ROI should include both immediate results and longer-term brand value, from search uplift and footfall to awareness and recall.
A billboard campaign is easier to measure when the objective, location strategy, creative and digital support are planned together from the start.
One Day Agency can help brands plan, buy, create and measure billboard campaigns across OOH, digital media, PPC and paid social.
Billboards can be highly effective, but their return is not always captured by one simple sales figure. A campaign may increase branded search, drive people into shops, support a launch, improve recall or make other channels perform better. To understand billboard ROI, brands need to look at the full role outdoor advertising plays in the customer journey.
At One Day Agency, billboard campaigns can be planned across billboard advertising, OOH advertising, digital OOH, media buying, programmatic advertising, local advertising and paid social.
What ROI Means for Billboard Advertising
ROI means return on investment. In advertising, it looks at the value created by a campaign compared with the money spent. With billboards, that value can show up in several ways.
Some results are direct, such as more store visits, sales in a target region or QR code scans. Others are less immediate, such as stronger brand recognition, higher trust or increased search activity after repeated exposure.
This is why billboard ROI should not be treated as a single number. Outdoor advertising often works by building memory and familiarity over time, while also supporting more measurable actions through search, social, retail and ecommerce.
Define the Commercial Objective First
Measurement becomes much easier when the campaign has a clear job. A billboard used to promote a store opening will need different metrics from one used to build national awareness.
Billboard campaigns can support:
Brand awareness
Branded search growth
Website visits
Retail footfall
Store launches
App downloads
Regional awareness
Product consideration
Event attendance
Sales uplift
The objective should guide the media plan. A local footfall campaign may need sites close to stores, while a brand campaign may need broader reach, higher frequency and a longer booking period.
Why Billboards Can Generate Return
Billboards give brands large-scale visibility in public spaces. They are hard to miss, often seen repeatedly, and can make a brand feel more established in a market.
Outsmart reported that UK OOH revenue reached £1.44bn, the highest annual figure recorded for the channel. That continued investment suggests advertisers still see strong value in physical visibility.
Billboards can also deliver concentrated reach in specific places. Bauer Media Outdoor notes that a single 48-sheet poster can generate more than 170,000 views in a fortnight, which can make the format useful for brands that need regional or route-based exposure.
Choose Metrics That Match the Goal
The best ROI metrics depend on what the campaign is trying to achieve. For a retailer, store visits and sales by location may matter most. For a direct-to-consumer brand, branded search and website traffic may be more important. For a brand campaign, awareness and recall may be the priority.
Useful billboard ROI metrics include:
Reach and frequency
Cost per thousand impressions
Branded search uplift
Direct website traffic
QR scans
Promo code use
Store visits
Footfall uplift
Sales by region
Brand awareness
Ad recall
Social mentions
For a deeper view of tracking methods, this guide on how to measure OOH advertising explains how brands can evaluate outdoor activity beyond impressions.
Look at Short-Term and Long-Term Results
Some billboard effects are visible during the campaign. Search demand may rise, website traffic may increase or footfall may improve in locations where media is live.
Other effects build more gradually. Repeated exposure can increase familiarity, trust and consideration. These brand effects may influence future purchases, even if they do not appear in week-one sales reports.
Profit Ability 2 found that advertising delivers an average short-term profit ROI of £1.87 for every £1 invested, increasing to £4.11 when sustained effects are included. The same study reported that Out of Home delivers a short-term ROI of £1.19 and a full ROI of £2.78.
That distinction matters. If outdoor advertising is judged only by immediate response, a large part of its commercial value can be missed.
ROI of Billboards
What Improves Billboard ROI?
Billboard performance depends on more than buying a large site. The return is shaped by how well the location, message and supporting channels work together.
The main drivers include:
A clear objective
Relevant site selection
Simple creative
Strong brand visibility
Enough frequency
Good location context
Suitable campaign length
Digital support
Creative plays a major role. A billboard has only a short window to communicate, so the idea needs to be quick to understand. The best-performing work usually has one message, one strong visual and a brand cue that is easy to remember.
For creative planning, this guide on how to design an effective billboard covers layout, hierarchy and readability. For format selection, this overview of billboard sizes can help match the campaign to the right placement.
Use Digital Media to Strengthen Measurement
Billboards often influence digital behaviour. Someone might see a roadside poster in the morning, search for the brand later, visit the website or convert after another online touchpoint.
This is why outdoor and digital should be planned together. Search, paid social, analytics and location data can help show whether the billboard campaign is creating demand.
Useful approaches include:
Tracking branded search before, during and after the campaign
Comparing website traffic in campaign regions
Using location-specific landing pages
Using unique promo codes
Reviewing QR code scans
Comparing exposed and non-exposed areas
Monitoring PPC and paid social performance during the campaign
The aim is not to force billboards into a purely digital attribution model. The aim is to build enough evidence to understand how outdoor visibility supports the wider funnel.
When ROI Is Less Direct
Some billboard campaigns are harder to measure with direct revenue alone. This is common for higher-value products, long buying cycles, brand campaigns or categories where people do research before converting.
In these cases, the ROI model needs to match the buying journey. A property campaign may track enquiries and search growth. An automotive campaign may track dealership visits and consideration. A financial services campaign may track awareness, trust and lead quality.
Billboards can create the first moment of recognition, while other channels move people closer to action.

“Billboard ROI is strongest when the campaign has a clear job. The site gives you visibility, but the strategy decides whether that visibility turns into search, footfall, enquiries or sales.” - Ricardo Seixas, CEO, One Day Agency
