TV, Digital, Out-of-Home: How to Split a Marketing Budget That Works

Allocating marketing budget across TV, digital, and out-of-home advertising is one of the most consequential decisions a marketing leader makes, and one of the least well-reasoned. Most splits are inherited from last year, reverse-engineered from what the media agency recommended, or built around what’s easiest to measure rather than what actually drives growth.

There is no universal formula. But there is a logical framework, and it starts with being honest about what each channel actually does, what your business needs right now, and what your measurement capability can genuinely support.

Why Most Budget Allocation Conversations Start in the Wrong Place

When I was running agency teams and sitting across from marketing directors in planning cycles, the budget conversation almost always started with channels. How much for TV this year? What’s the digital split? Are we doing OOH? The commercial objective, if it came up at all, was an afterthought used to justify a number someone had already decided on.

That sequencing is backwards. The right question is not “how do we divide the budget across channels?” It is “what does this business need to achieve in the next 12 months, and which combination of channels gives us the best probability of getting there?” Channel selection follows objective clarity. It does not precede it.

A brand launching into a new category needs broad reach and fast awareness. A mature brand defending market share needs different weight in different places. A direct-to-consumer business with a short purchase cycle has a completely different channel logic than a financial services brand where the sales cycle is measured in months. One framework cannot serve all of them.

If you want a broader view of how budget decisions fit into the wider operational picture, the Marketing Operations hub covers the structural and commercial decisions that sit behind effective marketing planning.

What Each Channel Actually Does (and What It Does Not)

The single most useful thing you can do before allocating budget is to be precise about what each channel is good for, stripped of the sales narrative from every media owner in the market.

Television, at its core, is a reach and salience engine. It puts your brand in front of large audiences simultaneously, with audio-visual impact that no other channel matches at scale. It builds mental availability over time. It is expensive, relatively slow to optimize, and almost impossible to attribute directly in a last-click model. None of that makes it ineffective. It makes it misunderstood by people who learned marketing through a performance dashboard.

Digital is a broad category that contains multitudes. Paid search captures existing demand. Paid social can build awareness or retarget warm audiences depending on how it is set up. Programmatic display operates somewhere in between. The common thread is that digital is measurable, adjustable in near real-time, and deeply efficient at the bottom of the funnel. It is also heavily saturated, subject to fraud, and systematically over-attributed in most measurement setups.

Out-of-home has had a quiet renaissance. Digital OOH in particular, with its ability to run contextually relevant creative in high-footfall environments and adjust dynamically, is a genuinely useful channel for brands that need to reinforce a message in the physical world. It works well in combination with TV and digital, amplifying a campaign rather than carrying one independently.

Understanding these distinctions matters because the temptation, especially in organizations where the CFO wants clean attribution, is to cut what you cannot measure and double down on what you can. That logic consistently over-invests in demand capture and under-invests in demand creation. Over time, it hollows out brand equity and makes performance marketing progressively more expensive.

The Brand Versus Performance Tension Is Real, and Most Budgets Get It Wrong

There is a well-established body of thinking in marketing effectiveness that points toward a roughly 60/40 split between brand-building and performance activity as a starting point for mature brands. I am not going to present that as a rule, because it is not one. But the underlying logic is sound: brand investment creates the conditions in which performance activity works. Without it, you are fishing in an increasingly small pond.

I have seen this play out in practice. Early in my career at lastminute.com, I ran a paid search campaign for a music festival that generated six figures of revenue within roughly a day. It felt like magic. It was not magic. It worked because the brand had already done the heavy lifting of making people aware that lastminute.com was a place you could buy festival tickets. The paid search campaign captured demand that brand activity had already created. Without the brand, the search clicks would not have been there.

Most performance marketers never see this dynamic because they are only looking at the bottom of the funnel. They see the click, the conversion, the ROAS. They do not see the TV spot or the OOH panel that put the brand in the consideration set three weeks earlier.

The practical implication for budget allocation is that you need to resist the pull toward pure performance efficiency and protect investment in channels that build the brand over time, even when those channels are harder to justify in a quarterly review.

How to Build a Budget Allocation Framework That Holds Up

Start with your commercial objective and be specific about it. Not “grow the brand” but “acquire 40,000 new customers in Q3 at a cost per acquisition below £28.” Not “increase awareness” but “shift prompted brand awareness from 34% to 42% among 25-44 year olds in the North West by year end.” Vague objectives produce vague allocations.

Once the objective is clear, map it to the funnel stage that needs the most attention. If awareness is low, you need reach. If consideration is stalling, you need relevance and message clarity. If conversion is the problem, you need performance optimization. Each of those problems has a different channel answer.

From there, consider your audience and where they actually spend their time. A B2B technology brand and a fast-moving consumer goods brand have almost nothing in common in terms of channel logic, even if they have similar budget sizes. Audience behavior drives channel selection. Channel selection drives budget weight.

Then look at your competitive context. If every competitor is heavy on TV and you are a challenger brand with a fraction of their budget, buying TV to compete head-on is probably a losing strategy. OOH in specific high-value locations, combined with targeted digital, might give you disproportionate presence in the moments that matter. If your competitors have abandoned TV, there may be an opportunity to own the channel cheaply. Context shapes the right answer.

Finally, be honest about your measurement capability. If you cannot measure the contribution of TV to downstream outcomes, do not pretend you can. Build a measurement plan that uses a combination of methods, including econometrics, brand tracking, and controlled experiments, rather than relying solely on last-click attribution. The goal is honest approximation, not false precision. Forrester has written about the need to move marketing planning away from gut instinct toward structured, evidence-based frameworks, and the measurement piece is where that shift is hardest to execute.

TV Allocation: When It Makes Sense and When It Does Not

Television earns its place in a budget when you need to reach a large audience quickly, when your category requires emotional storytelling, or when you are trying to shift brand perceptions at scale. It is most effective for brands with meaningful distribution and a product or service that benefits from mass awareness.

It is harder to justify for niche B2B products, hyper-local businesses, or brands at an early stage where the priority is learning rather than scaling. The minimum effective threshold for TV is higher than most people assume. A small budget spread across TV will often underperform the same money concentrated in digital, simply because it cannot achieve the frequency needed to have an effect.

Connected TV and streaming platforms have changed the calculus somewhat. Addressable TV allows for more precise audience targeting than linear, with lower minimum spend thresholds. For brands that want the impact of television without the cost of a mass buy, this is worth serious consideration. But be cautious about assuming that connected TV delivers the same brand-building effect as linear. The viewing context, attention levels, and ad environment are different.

When I was growing an agency from around 20 people to over 100, one of the things I learned was that the channels that built our reputation were not always the ones we could measure most easily. Thought leadership, industry presence, and word of mouth drove a disproportionate share of new business. The lesson translates directly to media planning: the channels that build brand are not always the ones that show up cleanest in a report.

Digital Allocation: Getting Beyond the Performance Trap

Digital deserves a more nuanced internal allocation than most budgets give it. Lumping paid search, paid social, programmatic display, and video into a single “digital” line and optimizing for blended ROAS is a recipe for systematically over-investing in the bottom of the funnel and starving the top.

Paid search, particularly branded search, is almost always efficient. It captures people who are already looking for you. The danger is treating that efficiency as evidence that search is creating demand, when it is mostly harvesting demand that other channels created. Protecting search budget makes sense. Treating it as the primary growth lever usually does not.

Paid social, when used well, can do genuine brand-building work at the top of the funnel. Video on social platforms, particularly longer-form content that tells a story, can shift brand perceptions and drive consideration. But the temptation to optimize for cheap clicks and low CPMs pushes social budgets toward formats and audiences that generate activity without generating value. Setting objectives for social at the awareness and consideration level, separate from conversion objectives, helps resist this pull.

Programmatic display is the channel where I have seen the most waste over the years. Cheap inventory is cheap for a reason. Viewability rates, brand safety issues, and the gap between reported impressions and actual human attention make programmatic a channel that requires rigorous governance. If you cannot verify where your ads are appearing and whether they are being seen, the efficiency numbers are largely meaningless. Forrester’s thinking on structured marketing planning is relevant here: discipline in channel selection and measurement design matters more than the specific allocation percentages.

Out-of-Home: The Underrated Channel in the Mix

Out-of-home is consistently undervalued in marketing budgets, partly because it sits awkwardly between the measurability of digital and the scale of TV, and partly because it requires creative thinking about context and placement rather than just audience targeting.

The strongest use cases for OOH are geographic concentration, contextual relevance, and campaign amplification. A brand that wants to dominate a specific city, appear at the moment when a consumer is physically close to a purchase decision, or reinforce a TV campaign with a consistent visual presence in the real world will find OOH genuinely effective.

Digital OOH has added flexibility that static formats never had. Dynamic creative that changes based on time of day, weather, or local events allows for relevance that was previously impossible in the outdoor environment. For brands with the creative infrastructure to take advantage of it, this is a meaningful capability.

The mistake I see most often with OOH is treating it as a standalone channel and expecting it to carry a campaign independently. It rarely does. Its power is in combination: reinforcing what TV has built, prompting recall at the point of decision, and creating physical-world presence for brands that are otherwise only encountered digitally.

The Measurement Problem Nobody Wants to Acknowledge

The single biggest distortion in marketing budget allocation is the measurement gap between channels. Digital is easy to measure in a last-click model. TV and OOH are not. This asymmetry systematically biases budget decisions toward digital, not because digital is more effective, but because it is easier to report on.

I have judged the Effie Awards, which are explicitly focused on marketing effectiveness rather than creative quality. One of the consistent patterns in winning work is that the most effective campaigns are almost never single-channel. They use TV to build reach and emotional connection, digital to target and convert, and OOH to reinforce presence. The measurement challenge is that no single attribution model captures the combined effect of all three.

Marketing mix modelling, done properly, is the closest thing to a solution. It uses statistical analysis of historical sales and marketing data to estimate the contribution of each channel to overall outcomes. It is not perfect, but it is significantly more honest than last-click attribution for multi-channel campaigns. If your budget is large enough to justify the investment, it is worth doing.

For smaller budgets, controlled experiments offer a practical alternative. Running a campaign in one region and not another, then comparing outcomes, gives you a real-world read on channel contribution that no attribution model can match. It requires discipline and patience, but it produces genuinely useful data.

The broader point is that your measurement framework should be designed before you finalize your budget allocation, not retrofitted afterward. If you cannot measure the contribution of a channel, you should either invest in the capability to do so or be honest that you are making a judgment call rather than a data-driven decision. Both are acceptable. Pretending a flawed model is giving you accurate answers is not.

For more on the operational and structural decisions that support effective budget management, the Marketing Operations hub is worth working through as a companion to this framework.

Practical Starting Points by Business Type

No allocation framework survives contact with reality unchanged, but starting points are useful. Here is how I would think about the channel mix for three common business contexts, with the caveat that these are directional, not prescriptive.

For a large consumer brand with significant market share and a substantial budget, a meaningful portion of spend should protect and build the brand through TV and OOH, with digital weighted toward consideration and conversion. The exact split depends on category dynamics and competitive context, but protecting brand investment is the priority. Cutting it to fund short-term performance activity is a trade that looks good in the next quarter and costs you in the next three years.

For a challenger brand or scale-up with a mid-sized budget, the logic shifts. You probably cannot afford to compete on TV at the scale needed to make it work efficiently. Concentrate digital investment in the channels where you can be genuinely competitive, use OOH selectively in high-value locations, and consider whether connected TV or streaming gives you a cost-effective entry into video without the minimum spend of linear television.

For a direct-to-consumer brand with a short purchase cycle and strong digital infrastructure, the natural weight is toward digital, but do not let that become an excuse to ignore brand entirely. Even DTC brands that have grown rapidly on performance marketing eventually hit a ceiling where the audience of people actively searching for them is exhausted. Building brand broadens that audience over time. Setting clear lead generation goals is a useful discipline for DTC brands handling the tension between short-term conversion and longer-term brand investment.

The Conversation You Need to Have With Your Finance Director

Budget allocation is not purely a marketing decision. It happens inside a commercial context where the finance director wants to see return on investment, the board wants predictable growth, and the CFO is looking for efficiency ratios. Marketing leaders who treat this as purely a channel planning exercise miss the political and commercial dimension that determines whether the budget actually gets approved.

The most effective approach I have found is to frame the budget conversation in terms of commercial outcomes rather than marketing activities. Not “we are spending £X on TV” but “TV investment is expected to drive Y percentage points of brand awareness growth, which our modelling suggests will contribute Z to revenue over the next 18 months.” Even if the model is imperfect, the framing demonstrates that you are thinking commercially rather than just spending the budget you have been given.

It also helps to be explicit about the time horizon of different investments. TV and OOH are longer-term investments. Their effects compound over time. Performance digital delivers in the short term. A budget that is entirely short-term will look efficient until it does not, and by then the brand equity erosion is already underway. Making this argument clearly, with evidence from your own data where possible, is the marketing leader’s job.

Structuring your team and planning process to support this kind of thinking is worth the investment. Resources like BCG’s work on agile marketing organizations and Mailchimp’s overview of the marketing planning process offer useful frameworks for building the operational discipline that good budget decisions require. Similarly, Optimizely’s thinking on brand marketing team structure is relevant for organizations trying to align team design with budget logic.
