Billboards Are Back. Here’s Why Smart Brands Never Left

Billboards and outdoor advertising never disappeared. They just got overshadowed by the performance marketing obsession of the last fifteen years, during which a generation of marketers convinced themselves that anything without a click-through rate was impossible to justify. That obsession is now unwinding, and out-of-home is having a moment that feels less like a comeback and more like a correction.

The brands that kept investing in outdoor during the digital gold rush did not do so out of nostalgia. They did it because billboards do something that performance channels structurally cannot: they reach people who are not already looking for you.

Why Outdoor Advertising Fell Out of Favour

The story of how billboards got sidelined is really a story about measurement anxiety. When digital advertising arrived with its dashboards and attribution models, it made everything else look primitive by comparison. You could see exactly how many people clicked, converted, and bought. Outdoor advertising offered none of that. So budget shifted, and kept shifting, toward channels that produced numbers.

I spent a significant part of my career watching this play out from inside agencies. At iProspect, we grew the team from around 20 people to over 100, and a large part of that growth was driven by the hunger for performance channels. Clients wanted accountability. They wanted to see the data. And performance marketing delivered it, in abundance.

The problem was that the data was telling an incomplete story. A lot of what performance marketing was being credited for was demand that already existed. People who were already going to buy, already searching, already in-market. The attribution model said the paid search ad converted them. What it could not say was whether the brand awareness built over months or years was what put them in the consideration set to begin with. Out-of-home does a lot of that foundational work, and it gets almost none of the credit.

This is not a theoretical concern. When I was judging the Effie Awards, one of the clearest patterns across the most effective campaigns was that the brands winning on long-term growth were almost always running broad-reach formats alongside their performance activity. The ones that had stripped everything back to lower-funnel channels tended to plateau. They were harvesting demand efficiently, but they had stopped creating it.

What Billboards Actually Do Well

Outdoor advertising is a reach medium. That sounds obvious, but it is worth being precise about what that means strategically. A billboard on a busy arterial road does not care whether the person driving past it is in-market. It does not require intent. It does not need a search query. It simply exists in the physical environment of people who might, at some point, become customers.

That passive reach is not a weakness. It is the mechanism by which brands build the kind of mental availability that drives future purchase. When someone eventually does enter a category, the brands they consider first are the ones they have encountered repeatedly over time, often without consciously registering those encounters. Outdoor advertising is one of the most efficient ways to generate that repeated exposure at scale.

There is a useful analogy from retail. A customer who walks into a clothes shop and tries something on is far more likely to buy than one who browses the window from the street. But the window display is what got them through the door. Billboards function similarly. They do not close the sale, but they create the conditions in which a sale becomes possible, by making a brand feel familiar, credible, and present before the customer is even thinking about buying.

Billboards also do something that most digital formats struggle with: they are genuinely hard to avoid. You can install an ad blocker. You can skip a pre-roll. You can scroll past a sponsored post in under a second. A billboard on your commute route is just there, every morning, whether you engage with it consciously or not. That passive exposure accumulates in ways that are difficult to measure but easy to underestimate.

The Measurement Problem Is Real, But Overstated

The honest answer to “how do you measure a billboard?” is that you cannot measure it with the same precision you can measure a paid search campaign. Anyone who tells you otherwise is selling something. But the leap from “imprecise” to “unmeasurable” is where a lot of marketers lose the thread.

There are legitimate proxy metrics for outdoor effectiveness. Brand tracking studies can capture shifts in awareness and consideration. Geo-based analysis can compare brand metrics or sales performance in markets with outdoor activity against control markets without it. Foot traffic data, now widely available through mobile location providers, can be used to understand whether exposure to outdoor formats correlates with store visits or online searches in a given area.

None of these are perfect. All of them involve assumptions. But that is true of almost every measurement approach in marketing, including the digital ones that get treated as gospel. Last-click attribution is not accurate. Multi-touch models are not accurate either. They are all approximations, and the question is whether your approximation is honest about its limitations or whether it is producing false confidence.

Marketing does not need perfect measurement. It needs honest approximation and the commercial judgment to act on incomplete information without pretending the information is complete. That is a skill that gets less attention than it deserves, partly because dashboards have trained a generation of marketers to expect certainty.

If you are working through how outdoor fits into a broader channel strategy, the Go-To-Market and Growth Strategy hub covers the frameworks for making those decisions without defaulting to whatever is easiest to measure.

Digital Out-of-Home Has Changed the Calculus

One of the most significant developments in outdoor advertising over the last decade is the rise of digital out-of-home, or DOOH. Digital screens in high-traffic locations have changed the economics of the format in ways that make it accessible to a much wider range of advertisers.

The traditional objection to outdoor was the commitment involved. A four-week static billboard buy in a premium location required significant upfront spend, with no ability to adjust creative mid-campaign. DOOH removes most of those constraints. You can run time-of-day targeting, change creative in real time, and buy programmatically in ways that would have been unimaginable in traditional outdoor planning.

This has practical implications for how brands should think about testing the format. A brand that previously could not justify a traditional outdoor buy can now run a DOOH test with a defined budget, specific location targeting, and the ability to iterate on creative. The barrier to entry has dropped considerably, which means the “we can’t afford outdoor” argument has become significantly less defensible for mid-market advertisers.

Programmatic DOOH also opens up the possibility of coordinating outdoor with digital campaigns in ways that create genuine channel collaboration, without the word becoming meaningless. Running outdoor in a specific geography at the same time as targeted digital activity in that area can reinforce brand messages across environments, which is meaningfully different from running the same ad in two places.

Where Billboards Fit in a Go-To-Market Plan

Outdoor advertising is not a standalone strategy. It is a channel within a channel strategy, and its effectiveness depends heavily on what surrounds it. A billboard running in isolation, without supporting digital or retail activity, is doing a fraction of the work it could do if it were coordinated with the rest of the plan.

The most effective use of outdoor I have seen in practice is as a broad-reach layer that operates above more targeted activity. You use outdoor to build awareness and familiarity at scale, and then you use more targeted formats to reach people who are showing intent signals. The outdoor activity does not need to drive direct response. Its job is to make the targeted activity more efficient by ensuring the brand is already familiar when someone encounters it in a more direct-response context.

This is the model that BCG has described in the context of commercial transformation and go-to-market strategy: growth comes from coordinated investment across the funnel, not from optimising any single layer in isolation. Outdoor sits at the top of that structure, doing the brand-building work that makes everything downstream more effective.

For product launches specifically, outdoor can play a critical role in establishing presence quickly in a defined geography. BCG’s work on launch strategy consistently points to the importance of rapid awareness-building in the early stages of a launch, and outdoor is one of the few formats that can achieve genuine mass reach in a compressed timeframe.

Creative Constraints Are a Feature, Not a Bug

Outdoor advertising imposes constraints that most digital formats do not. You have seconds, not minutes. You have a headline and an image, not a product carousel or a video with captions. Those constraints force a discipline that a lot of marketing teams find genuinely uncomfortable, because it exposes whether the brand actually has something clear to say.

Early in my career, I was in a brainstorm for Guinness at an agency where the founder had to leave mid-session for a client meeting. He handed me the whiteboard pen on his way out the door. My internal reaction was something close to panic. But what that moment taught me was that the discipline of articulating a brand idea clearly, under pressure, in front of a room, is exactly the skill that outdoor advertising demands. You cannot hide behind a long-form landing page or a six-second pre-roll with a skip option. You have to say something that lands immediately.

The brands that do outdoor well tend to be the ones that have done the positioning work properly. They know what they stand for, they can express it in a single sentence, and they can translate that sentence into a visual that works at 70 miles an hour. The brands that struggle with outdoor tend to be the ones that have not done that work, and the billboard format exposes that gap ruthlessly.

If your brand cannot communicate its value proposition in five words and an image, outdoor advertising is not the problem. The positioning is the problem.

The Audience Reach Argument Is Stronger Than It Looks

One of the persistent criticisms of outdoor advertising is that it lacks targeting precision. You cannot serve a billboard only to 35-to-44-year-old homeowners with a household income above a certain threshold. You are reaching everyone in a given location, most of whom will not be your customer.

That criticism assumes that reaching non-customers is waste. It is not. Reaching people who are not currently in-market is how you build the brand awareness that makes them more likely to consider you when they eventually do enter the category. The logic of hyper-targeting, taken to its extreme, produces a brand that is only ever talking to people who already know it exists. That is a maintenance strategy, not a growth strategy.

Growth requires reaching new audiences. That is not a philosophical position. It is a commercial reality. If your addressable market is larger than your current customer base, and it almost certainly is, then some portion of your marketing investment needs to be reaching people who have not yet encountered your brand. Outdoor advertising is one of the most cost-effective ways to do that at scale, particularly in defined geographies where you are trying to build local market share.

The pipeline and revenue potential research from Vidyard makes a related point about untapped audiences in go-to-market contexts: the opportunity is almost always larger than the current funnel suggests. Outdoor advertising is one mechanism for accessing that latent opportunity.

Location Strategy Matters More Than Most Brands Acknowledge

Not all outdoor inventory is equal, and the planning decisions around location are where a lot of campaigns either succeed or fail before a single piece of creative goes up. A billboard in the wrong location, no matter how good the creative, is not doing the job.

Effective outdoor planning starts with understanding where your target audience actually is, not where you assume they are. High-traffic commuter routes are the obvious choice, but they are also the most expensive and the most competitive. There is often more value in identifying the specific locations where your audience is most receptive, near retail environments, in proximity to competitor locations, or in the specific neighbourhoods where your customer base is concentrated.

Retail proximity is particularly underused as a planning criterion. A billboard within a short distance of a point of sale can function as a last-mile reminder that activates purchase intent that already exists. This is a different use case from the broad awareness play, and it requires different creative thinking. The message needs to be more directional, more action-oriented, and more specific to the purchase context.

Airport advertising is another location category that gets treated as a prestige play when it is often a genuinely strategic one. If your audience is business travellers or frequent fliers, airport dwell time gives you something most outdoor formats cannot: an audience that is stationary, not in a hurry, and often in a receptive mental state. The cost per relevant impression can be lower than it appears when you account for audience quality.

How to Evaluate Outdoor Against Other Channel Options

The question of whether to invest in outdoor advertising is in the end a channel allocation question, and it should be answered with the same rigour you would apply to any other channel decision. That means being honest about what you are trying to achieve, at what stage of the funnel, and whether outdoor is the most efficient way to achieve it.

If you are trying to drive immediate direct response, outdoor is probably not your primary vehicle. If you are trying to build brand awareness in a defined geography, it may be the most cost-effective option available. If you are launching a new product and need to establish presence quickly, outdoor can do things that digital cannot, particularly in terms of physical scale and environmental presence.

The channel comfort trap is real. Many marketing teams default to the channels they know, the ones they have measurement frameworks for, the ones that produce reports that are easy to present to senior stakeholders. Outdoor advertising requires a different kind of commercial confidence, the willingness to invest in something whose returns are real but not immediately legible in a dashboard.

Growth hacking frameworks, like those outlined by CrazyEgg on growth hacking principles, tend to focus on digital experimentation loops. That is a legitimate approach for certain growth problems. But it is not the only approach, and for brands trying to build genuine market presence rather than optimise an existing funnel, outdoor advertising deserves a seat at the planning table that it rarely gets.

Creator-led campaigns and content strategies, as explored in resources like Later’s go-to-market with creators work, can complement outdoor activity well, particularly when you are trying to build awareness across both physical and digital environments simultaneously. The outdoor format establishes broad presence; the creator content provides the context and personality that turns that awareness into something more specific.

The broader question of how outdoor fits within a full go-to-market plan is something I cover in more depth across the Growth Strategy hub, alongside channel planning, audience strategy, and the measurement frameworks that help you make better decisions with incomplete information.

The Brands Getting This Right

The brands that have maintained or grown their outdoor investment over the last decade share a few characteristics. They tend to have strong positioning, because outdoor forces you to have it. They tend to have a long-term perspective on brand building, because outdoor does not produce overnight results. And they tend to have senior stakeholders who understand that not everything worth doing can be attributed in a spreadsheet.

What they are not doing is treating outdoor as a vanity exercise. The best outdoor campaigns I have seen in twenty years of agency work were strategically precise: right location, right message, right moment in the brand’s commercial cycle. They were not running billboards because it looked impressive. They were running them because it was the right channel for the job.

That commercial discipline is what separates effective outdoor advertising from expensive wallpaper. A billboard that is in the right place, saying the right thing, to an audience that will eventually be in-market for what you sell, is doing serious strategic work. A billboard that exists because someone thought it would be nice to have one is doing nothing except spending budget.

Agile marketing frameworks, as Forrester has examined in the context of scaling agile approaches, increasingly emphasise the importance of testing and iterating across channels. Outdoor is not exempt from that discipline. DOOH in particular makes it possible to run genuine tests, vary creative, and learn what works before committing to larger investments. That is a more sophisticated approach than the traditional “book a site for four weeks and see what happens” model, and it makes outdoor more defensible as a channel choice.
