Billboards Still Work. Most Brands Just Use Them Wrong

Billboards and advertising in physical space never went away. They got cheaper to buy, cheaper to produce, and considerably easier to measure than they were a decade ago, yet most brands treat them as a legacy medium, something you do when you have budget left over or when someone in the C-suite wants to see the company name on the motorway. That framing is wrong, and it costs brands real growth.

Out-of-home advertising, when it is planned with intent rather than sprayed for visibility, functions as one of the most efficient tools available for building reach among audiences who are not already in your funnel. That is precisely what most brands need more of, not better retargeting of people who already know them.

Why Brands Keep Underestimating Out-of-Home

Earlier in my career I was firmly in the lower-funnel camp. I believed, genuinely, that the closer you got to the point of purchase, the more efficient your marketing became. It took years of managing significant budgets across dozens of categories before I started to question that assumption properly. What I eventually understood is that a lot of what performance marketing gets credited for, the conversions, the attributed revenue, the tidy ROAS numbers, was going to happen anyway. You were capturing intent that already existed. You were not creating it.

Out-of-home sits at the other end of that spectrum. It is not trying to intercept someone who is already searching. It is trying to plant something in the mind of someone who is not thinking about your category at all. That is a harder job to measure and a harder case to make in a quarterly business review. It is also, for most brands with growth ambitions, the more important job.

If you are thinking about where billboard advertising fits within a broader commercial strategy, the go-to-market and growth strategy hub on this site covers the frameworks that make sense of that question. OOH does not sit in isolation. It is a channel decision within a larger plan, and the plan has to come first.

What Billboards Actually Do in an Advertising Plan

There is a persistent confusion in marketing between what a channel does and what it is credited for. Billboards rarely get credited for much in a standard attribution model. Someone sees a poster on their commute, thinks nothing of it consciously, encounters the brand again online three weeks later, clicks an ad, and converts. The performance channel takes the credit. The billboard gets cut in the next planning cycle.

This is not a billboard problem. It is a measurement problem, and more specifically, a mental model problem. Out-of-home advertising operates through familiarity, salience, and repeated low-level exposure. It works the way that most brand advertising works, by making a brand feel known and credible before the purchase moment arrives. The mechanism is not instant and it is not linear, which makes it uncomfortable for teams that have been trained to think in click-through rates and cost-per-acquisition.

BCG has written on this tension between brand investment and performance efficiency in the context of go-to-market strategy, noting that the organisations that get this balance right tend to outperform those that optimise too hard for short-term measurable returns. The principle applies directly to how brands should think about OOH within a media mix.

Billboards do three things well. They build reach among people who are not actively looking for you. They create a sense of scale and presence, particularly in local or regional markets where that impression matters commercially. And they provide contextual relevance in a way that digital advertising rarely can, because the location of a billboard is a creative variable in itself.

Location Is Not Just a Media Decision

I have sat in enough media planning sessions to know that location selection for OOH is almost always treated as a reach and frequency exercise. You pick the sites with the highest footfall, negotiate the best rate, and move on. That approach misses the most interesting thing about physical advertising, which is that where a message appears changes what the message means.

A billboard for a running shoe brand positioned at the entrance to a park on a Sunday morning is a different piece of communication than the same creative on a retail high street on a Thursday afternoon. The audience is different, the mindset is different, and the relevance of the message is different. Most brands do not think at that level of granularity because it requires more planning time and more creative flexibility than a single national execution allows. But the brands that do think that way tend to get considerably more out of the medium.

Context is not just about audience targeting. It is about the relationship between the message, the environment, and the moment. Digital advertising has trained us to think about targeting in terms of demographics and behavioural data. OOH targeting is more physical and more intuitive, and in some respects more honest, because you are making an explicit choice about where your brand shows up in the real world.

Digital Out-of-Home Has Changed the Calculus

The shift to digital out-of-home screens has made the medium more flexible and, to a degree, more measurable. You can now run time-specific creative, change messaging based on weather or local events, and buy inventory programmatically in ways that were impossible with traditional static formats. That is genuinely useful, and it has lowered the barrier to entry for brands that previously could not afford the production costs of a full OOH campaign.

What it has not done is change the fundamental logic of the medium. Digital OOH is still a broadcast channel. It still builds reach through repeated exposure. It still operates on a longer timescale than search or social. The mistake I see regularly is brands applying digital performance logic to DOOH because the buying mechanism now resembles programmatic display. They set narrow targeting parameters, run short bursts, and then wonder why the results look thin. You cannot run a two-week DOOH campaign and expect to see brand lift in the same way you would see conversion data from a paid search campaign. The timescales are different and the mechanisms are different.

Forrester’s work on go-to-market planning challenges touches on a related issue, which is the tendency for organisations to apply the wrong measurement frameworks to channels that require patience and cumulative investment. OOH is a clear example of where that mismatch creates bad decisions.

The Creative Problem With Most Billboard Advertising

Most billboard creative is bad. Not bad in the sense of being offensive or embarrassing, but bad in the sense of being completely forgettable. It is usually an adaptation of a digital or print asset, produced by someone who has not thought carefully about how the format works, and approved by a client who is more concerned with brand compliance than communication effectiveness.

Good billboard creative follows a set of constraints that are different from almost every other format. You have roughly three seconds of attention from a moving audience. You need one idea, not three. You need contrast and legibility at distance. And you need to earn a reaction, whether that is a smile, a moment of recognition, or a genuine surprise, because a neutral response is functionally the same as no response at all.

I remember the first time I was handed responsibility for a major creative brainstorm, early in my agency career, for Guinness. The founder had to leave for a client meeting and literally handed me the whiteboard pen. My immediate internal reaction was something close to panic. What I learned from that experience, and from many similar ones since, is that the constraint of a brief forces clarity. Billboards are the ultimate constrained format. They punish vagueness and reward precision. Most brands are not precise enough in their thinking to use them well.

The creative brief for a billboard campaign should answer a single question before anything else: what is the one thing this poster needs to make someone feel or think? If the answer is a list, the brief is not ready.

How OOH Fits Into a Go-To-Market Plan

Billboard advertising is not a strategy. It is a channel. The distinction matters because I have seen brands use OOH as a substitute for strategic clarity, buying poster sites because it feels like a confident market statement, without being clear on what they are trying to achieve or who they are trying to reach. That is an expensive way to feel good about your marketing without actually doing any.

When OOH works well in a go-to-market context, it is usually because it is doing one of three specific jobs. It is building awareness in a new geographic market where the brand has low penetration. It is reinforcing a brand message that is being amplified across other channels simultaneously. Or it is creating a sense of local presence for a brand that needs to feel less remote and more embedded in a community. Each of those jobs requires a different approach to site selection, creative, and duration.

BCG’s analysis of go-to-market strategy in financial services makes a point that translates directly here: channel decisions only make sense when they are downstream of audience and objective decisions. That sequencing is exactly right. You do not start with the billboard. You start with who you are trying to reach, what you need them to think or feel, and whether OOH is the right environment to do that work.

The broader frameworks for making those decisions, how to sequence channels, how to allocate budget across brand and performance, how to plan for growth rather than just efficiency, are covered in the go-to-market and growth strategy hub. Channel selection is always a downstream decision, and getting the upstream thinking right is what makes the difference.

Measuring Billboard Advertising Without Fooling Yourself

The measurement question around OOH is one of the most honest conversations you can have in a marketing team, because it forces you to confront what you actually believe about how advertising works. If you believe that every pound of marketing spend should be directly attributable to a specific outcome, OOH is going to be a difficult channel to justify. If you believe that brand salience and reach among new audiences create commercial value over time, even when that value is hard to isolate, then OOH becomes considerably easier to defend.

There are practical measurement approaches that add rigour without pretending to precision that does not exist. Brand tracking studies, run before and after a campaign, can show movement in awareness and consideration metrics. Geo-testing, running campaigns in some markets and not others and comparing sales data, can provide a reasonable read on commercial impact. Search volume uplift in areas where OOH is running is another imperfect but useful signal. None of these approaches give you a clean attribution number, and that is fine. The goal is honest approximation, not false precision.

Behavioural analytics tools can help you understand what happens to web traffic and on-site behaviour in markets where OOH is active. Hotjar and similar tools are useful for understanding how audiences interact with your digital presence, which can be one indicator among several when you are trying to read the downstream effects of an OOH campaign. what matters is not to treat any single data source as definitive.

I have managed enough large media budgets to know that the brands which abandon OOH because they cannot attribute it precisely are often the same brands that end up over-indexed on retargeting and under-indexed on reach. Their performance numbers look efficient quarter by quarter. Their brand health metrics quietly erode. And then one year the growth stops and no one is quite sure why.

When Billboards Are the Wrong Answer

Not every brand should be running OOH. There are situations where it is genuinely the wrong channel, and being honest about that is part of good planning.

If your brand has very low awareness and your primary objective is direct response, OOH is unlikely to be your most efficient first investment. Build some baseline awareness through channels where you can test and learn more quickly, then consider OOH as you scale. If your target audience is highly specific and geography does not map cleanly onto that specificity, the broad reach of OOH becomes a cost rather than a benefit. And if your creative is not ready, if you do not have an idea that can survive the constraints of the format, running a billboard campaign will not fix that. It will just make the weakness more visible.

The honest version of media planning acknowledges that channels have genuine strengths and genuine limitations, and that the job is to match the right channel to the right objective, not to justify the channel you already bought. OOH is a powerful medium when it is used with intent. When it is used as a default or a vanity buy, it is an expensive way to feel like you are doing something.

Growth hacking approaches, the kind documented by Semrush in their analysis of growth tactics, tend to focus heavily on digital and product-led channels. That is appropriate for early-stage businesses finding product-market fit. But as brands scale and the low-hanging fruit of existing intent gets picked, the case for investing in reach, including OOH, gets stronger. The brands that figure this out before their growth plateaus are the ones that tend to sustain it.

Integrating OOH With the Rest of Your Media Plan

The most effective OOH campaigns I have seen were never standalone. They were part of a coordinated effort where the same idea, or at least the same strategic territory, was showing up across multiple touchpoints simultaneously. The billboard created the initial impression. Social reinforced it. Search captured the intent that was generated. The campaign worked because the channels were doing different jobs in sequence, not competing for the same attribution credit.

Creator-led content has become an increasingly important part of how brands amplify OOH beyond the physical site. A well-placed billboard that generates organic social content, people photographing it, sharing it, commenting on it, extends the reach of the original media buy considerably. Later’s work on creator-led go-to-market campaigns highlights how brands are increasingly thinking about the earned amplification potential of paid placements, including physical ones. If your OOH creative is interesting enough to photograph, you are getting more than you paid for.

That integration thinking extends to timing. OOH works better when it is running at the same time as other brand activity, not in isolation. A brand that runs a television campaign and simultaneously activates OOH in key markets creates a reinforcement effect that neither channel achieves alone. The consumer who sees the TV ad and then encounters the poster on their commute is getting a different signal than someone who only sees one or the other. Repetition across formats is not redundancy. It is how memory structures get built.

What Good OOH Planning Actually Looks Like

Good OOH planning starts with a clear brief that specifies the audience, the geography, the objective, and the single message the campaign needs to land. It involves site selection that is driven by audience behaviour, not just footfall data. It requires creative that has been developed specifically for the format, not adapted from something else. And it includes a measurement approach that is agreed before the campaign runs, not reverse-engineered afterwards.

The planning process should also include an honest conversation about duration. OOH is not a medium that rewards short bursts. Awareness builds through repeated exposure over time, and a two-week campaign in a market where you have low penetration is unlikely to move the needle in any meaningful way. If the budget only allows for a short run, it is worth questioning whether OOH is the right allocation at all, or whether concentrating the spend in fewer, higher-impact sites for longer would be more effective than spreading it thinly.

I spent a significant part of my agency career working across thirty-odd industries, and one pattern that held across almost all of them was that brands which planned OOH with the same rigour they applied to digital channels consistently got better results than those that treated it as a creative showcase or a boardroom vanity project. The medium is not complicated. The discipline required to use it well is the same discipline required to use any channel well: clarity of objective, specificity of audience, honesty about measurement.

If you are building or refining your broader marketing approach and want a framework for thinking about where OOH fits, the growth strategy hub covers the planning principles that sit above individual channel decisions. Channel tactics only make sense in the context of a clear growth strategy, and that strategy is where the real work happens.
