Half Your Marketing Budget Is Wasted. Here’s Why That’s Not the Problem
“Half my marketing budget is wasted. I just don’t know which half.” John Wanamaker said it over a century ago, and marketers have been quoting it ever since, usually with a knowing laugh and a shrug. The quote has survived because it describes something real. But the way most people use it has become a way to avoid the harder conversation, which is not whether waste exists, but whether you are doing anything serious about it.
Waste in marketing is not a mystery to be accepted. It is a management problem to be worked on. The quote is a starting point, not a conclusion.
Key Takeaways
- The Wanamaker quote describes a real problem, but quoting it without acting on it is just expensive fatalism.
- Most marketing waste is not caused by bad channels. It is caused by bad targeting, bad measurement, and bad prioritisation.
- Zero-based budget thinking forces you to justify spend from scratch rather than defending last year’s allocations by default.
- Attribution will never be perfect, but honest approximation is far more useful than false precision or giving up entirely.
- The goal is not to eliminate waste. It is to reduce it deliberately, reinvest what you recover, and build a clearer picture over time.

What Did Wanamaker Actually Mean?
John Wanamaker was a Philadelphia retailer in the late 1800s who is widely credited with pioneering department store advertising. The quote about wasted budget is often cited as evidence that marketing measurement has always been broken. That reading is convenient, but it misses the point.
Wanamaker was not throwing his hands up. He was making an observation about the limits of the tools available to him at the time. He had no click-through rates, no conversion tracking, no media mix modelling. He was working with newspaper ads, direct mail, and foot traffic counts. Given those constraints, a 50% uncertainty rate was probably quite good.
The problem today is that marketers use the quote as a comfort blanket. We have access to tools Wanamaker could not have imagined, and yet the quote gets wheeled out to justify the same shrug he was making in 1880. That is not humility. That is abdication.
If you are spending seriously on marketing and your honest answer to “what’s working?” is still “we don’t really know,” that is a management problem, not an industry truth.
Is the 50% Figure Still Accurate?
Nobody knows. And that is the point. The 50% figure was never based on data. It was an intuition from a man running a retail business before mass media existed. The number has stuck because it feels plausible, not because anyone has measured it.
What we do know is that waste exists in every marketing budget, at every scale. I have managed hundreds of millions in ad spend across more than 30 industries, and I have never seen a budget without fat in it. The question is always how much, where, and whether you care enough to find out.
In paid search, waste often comes from broad match keywords pulling irrelevant traffic, campaigns running to audiences who already converted, or budgets allocated to terms with high volume but low commercial intent. In paid social, it tends to be frequency problems, audience overlap, or spend going to placements that look good in platform dashboards but drive nothing downstream. In traditional media, it is much harder to isolate, which is part of why the Wanamaker quote resonates so strongly with broadcast advertisers.
The waste is real. The 50% is a guess. And using a guess from the 1800s as your benchmark in 2026 is not a strategy.

Where Does Marketing Waste Actually Come From?
Most marketing waste does not come from choosing the wrong channel. It comes from poor execution within channels, weak targeting, and a failure to connect spend to outcomes in any meaningful way. Let me be more specific.
Audience Problems
You can be in the right channel and still waste most of your budget by talking to the wrong people. I have seen brands running awareness campaigns to audiences who were already customers, retargeting users who had churned and would never return, and serving ads to demographics that looked right on paper but had no actual purchase intent. Targeting has never been more sophisticated, and yet audience waste remains one of the most common problems I see when I look under the bonnet of a new account.
Measurement Problems
When I was at iProspect, growing the team from around 20 people to over 100 and moving the business from loss-making to one of the top five agencies in the UK, one of the most consistent battles was around measurement. Clients wanted clean attribution. Platforms were happy to provide it, because platform attribution almost always flatters the platform. Last-click models gave search all the credit. View-through models gave display all the credit. Everyone was claiming the conversion, and the client was paying for all of them.
Bad measurement does not just obscure waste. It actively encourages more of it, because channels that look productive in a broken model attract more budget, and channels that are genuinely working but harder to track get cut.
Inertia Budgeting
This is probably the most underappreciated source of waste in marketing. Most budgets are built by taking last year’s budget and adjusting it slightly up or down. The channels that got budget last year get budget this year, because changing the allocation requires someone to make a case for the change, and that is uncomfortable. Nobody wants to be the person who killed the TV budget or pulled out of a long-standing sponsorship.
The result is that spend calcifies around historical decisions rather than current evidence. Channels that were right three years ago continue to receive money even when the market has shifted. This is not negligence. It is a very human response to uncertainty and organisational friction. But it is still waste.
Creative Waste
Running the right message to the right audience at the right time is how good advertising works. Running the wrong message, or the same message to the same audience too many times, is how media spend gets wasted regardless of how well the channel is set up. Creative fatigue is a real and measurable phenomenon in digital channels. In broadcast, it is harder to see, which means it tends to go on longer.
Teams that invest heavily in media planning and almost nothing in creative iteration are essentially optimising the delivery of messages that stopped working months ago.
Why Zero-Based Budgeting Changes the Question
The standard budgeting process starts with what you spent last year. Zero-based budgeting starts with a blank page and asks: if we were building this budget from scratch, based on what we know now, what would we fund and why?
This is a harder conversation. It requires you to justify every line of spend rather than defend it by precedent. But it is also a more honest one. When I have run zero-based reviews with clients, the most common outcome is not that the total budget changes dramatically. It is that the allocation shifts significantly, because some things that had been running on autopilot for years could not survive the scrutiny of a fresh justification.
The BCG work on agile marketing organisation makes a related point: the ability to reallocate budget quickly in response to performance data is one of the clearest differentiators between marketing functions that drive growth and those that just spend money. Zero-based thinking is one way to build that muscle.
It does not need to be a full zero-based exercise every year. Even applying the discipline to 20% or 30% of your budget, the parts that are hardest to justify, can surface waste that has been invisible for years.
The Attribution Problem Is Real, But It Is Not Unsolvable
Attribution is the process of deciding which marketing activity gets credit for a sale or a conversion. It has always been imperfect, and it is getting harder as privacy regulations tighten, cookies disappear, and walled gardens like Google and Meta reduce the data they share. The ongoing scrutiny around data privacy from major platforms is not going away, and it will continue to affect what marketers can measure.
But imperfect attribution is not the same as no attribution. The mistake is treating measurement as binary: either you have perfect data or you have nothing. Most serious marketing operations sit somewhere in between, and the goal is to make honest, directionally correct decisions with the data you have, rather than waiting for certainty that will never arrive.
When I was at lastminute.com, I ran a paid search campaign for a music festival that generated six figures of revenue in roughly a day. The measurement was not perfect. We were working with early-generation tracking tools and a lot of manual reconciliation. But we had enough signal to know it was working, to scale it fast, and to justify the spend. That is what honest approximation looks like in practice.
The tools available now are dramatically better than what we had then. Teams like the one Unbounce built from one to 31 people have shown that you can build rigorous measurement practices at scale without needing a perfect data infrastructure. What you need is clarity about what you are trying to measure, consistency in how you measure it, and the discipline to act on what you find.
Tools like Hotjar can add a behavioural layer to quantitative data, helping you understand not just what users are doing but where the experience is breaking down. That kind of qualitative signal is often more useful for diagnosing waste than another attribution model.
How to Actually Reduce Marketing Waste
There is no single fix. But there are a set of practices that consistently surface waste and create the conditions for better decisions.
Audit Your Audience Targeting Quarterly
Pull your audience segments and ask whether they still reflect your actual customer. Markets shift. Products evolve. The audience you defined 18 months ago may not be the audience you should be targeting today. Suppression lists, exclusion audiences, and frequency caps are basic hygiene, but they are also the first things that get neglected when teams are busy.
Build a Single Source of Truth for Performance Data
If your paid search team, your social team, and your leadership team are all looking at different dashboards with different attribution windows, you will never agree on what is working. The numbers will always be in conflict, and the loudest voice in the room will win the budget argument rather than the best evidence. Standardising on a shared reporting framework, even an imperfect one, is more valuable than having five sophisticated but incompatible measurement systems.
Run Incrementality Tests
Incrementality testing asks a simple question: would this sale have happened anyway, without this ad? It is one of the most powerful tools for identifying waste, because it strips away the noise of attribution and asks whether your marketing is actually causing outcomes rather than just correlating with them. Geo holdout tests, matched market tests, and platform-native lift studies are all ways to get at this question. None of them are perfect. All of them are more honest than last-click attribution.
Treat Creative as a Performance Variable
If you are not testing creative systematically, you are probably running ads that stopped working months ago. Creative testing does not need to be a massive production. Even simple A/B tests on headlines, imagery, or calls to action can surface significant performance differences. The teams that treat creative as a fixed cost rather than a performance lever tend to have the most creative waste in their budgets.
Apply Zero-Based Thinking to Your Lowest-Confidence Spend
You do not need to zero-base your entire budget to get the benefit. Identify the 20% or 30% of spend where you have the least confidence in the return, and require that it justify itself from scratch. This is where inertia budgeting tends to hide, and it is where the most recoverable waste usually sits.
The Waste You Should Not Try to Eliminate
Not all marketing waste is bad. Some of it is the cost of doing business in channels where you cannot fully control who sees your message. Some of it is the price of experimentation, running things that do not work in order to find the things that do. Some of it is brand investment that will not show up in this quarter’s numbers but is building something real over time.
When I judged the Effie Awards, one of the things that struck me most was how many of the most effective campaigns involved significant upfront spend with no guarantee of return. The brands that won were not the ones that had eliminated all risk from their marketing. They were the ones that had made deliberate, informed bets and backed them with conviction. That requires some tolerance for waste.
The goal is not a zero-waste marketing budget. That budget does not exist, and if it did, it would probably be too conservative to drive growth. The goal is intentional spend, where you know why you are spending, what you expect to get back, and how you will know if it is working.
Influencer marketing is a good example of a channel where waste is often cited as a reason to avoid it, when in reality the issue is usually poor planning and unclear objectives. The Later guide to influencer marketing planning makes the point that the brands getting consistent results from influencer spend are the ones who treat it like any other performance channel, with clear briefs, defined metrics, and a process for evaluating what worked.
The Wanamaker quote will keep getting used. It will keep appearing in conference decks and agency credentials and LinkedIn posts. That is fine. But the next time someone uses it to close down a conversation about measurement or accountability, push back. The question is not whether waste exists. The question is whether you are taking it seriously.
