Marketing Defined: What the Textbooks Get Wrong

Marketing is the process of identifying what people want, creating something worth wanting, and making sure the right people know it exists. That definition sounds simple. The execution is where most companies fall apart, not because they lack tactics, but because they misunderstand what marketing is actually for.

The textbook definitions are technically correct and practically useless. “Marketing is the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.” Fine. But that tells you nothing about why most marketing fails to move a business forward, or why the discipline keeps getting reduced to a collection of channel tactics dressed up as strategy.

Marketing exists to grow a business. Not to generate impressions, not to win awards, not to produce content. To grow a business. Everything else is a means to that end, and losing sight of it is the most common and costly mistake I see.

What Marketing Actually Is

Strip away the frameworks, the funnels, and the channel debates, and marketing comes down to three connected problems. First, understanding who you are trying to reach and what they care about. Second, ensuring what you offer is genuinely suited to those people. Third, making that offer visible and compelling enough that the right people choose it over alternatives.

These three problems are not sequential. They interact constantly. A change in your audience changes what you need to offer. A change in your offer changes how you communicate it. A change in how you communicate changes which audiences you reach. Marketing, done properly, is a continuous loop of adjustment, not a one-time campaign or an annual plan.

The reason this matters is that most organisations treat marketing as one of those three problems in isolation. They hire a communications team and call it marketing. Or they invest in product development without any commercial lens on what the market actually wants. Or they run campaigns without a clear understanding of who they are talking to or why those people should care. Fragmentation is how good marketing intentions produce mediocre commercial outcomes.

I spent years running agencies where clients would come to us with a communications brief and wonder why the results were flat. The honest answer, which we did not always say loudly enough, was that their problem was not a communications problem. It was a positioning problem, or a product problem, or an audience problem. You cannot advertise your way out of a fundamentally misaligned offer. You can only spend faster.

Why the Narrow Definition Costs Companies Money

When a business defines marketing as advertising, or as digital, or as the team that manages the website and social channels, it creates a structural problem. The people responsible for understanding customers and shaping how the business responds to them are excluded from the decisions that matter most. Pricing, product development, distribution, customer experience: these are all marketing decisions, whether or not the marketing team is in the room when they are made.

Philip Kotler’s definition of marketing as the management process responsible for identifying, anticipating, and satisfying customer requirements profitably gets closer to the truth. The word “profitably” is doing important work there. Marketing is not customer service, not brand management, not content production. It is a commercial function. Its job is to help a business grow sustainably, and that requires an understanding of economics, not just communication.

The narrow definition also produces narrow metrics. If marketing is defined as advertising, then marketing success is measured in advertising terms: impressions, clicks, cost per acquisition. These metrics are not worthless, but they measure activity rather than outcome. A team optimising for cost per click can deliver excellent cost per click while the business loses market share. I have seen it happen, more than once, with large budgets and talented people who were simply optimising for the wrong thing because the definition of marketing they were working from was too small.

Understanding how marketing connects to broader commercial outcomes is something I explore throughout the Go-To-Market and Growth Strategy hub. The relationship between how you define marketing and how you measure it is one of the most consequential decisions a business makes, and it rarely gets the deliberate attention it deserves.

The Four Ps Are Still Right. The Problem Is How They Get Used.

The marketing mix, product, price, place, and promotion, has been taught in business schools since the 1960s. It gets dismissed as outdated by people who have not thought carefully about why it has lasted. The four Ps are not a checklist. They are a framework for thinking about the full scope of what marketing involves.

Product is the foundation. What you are offering has to be genuinely suited to the people you are trying to reach. This sounds obvious. In practice, companies routinely try to market products that are not quite right for the audience they are targeting, and they compensate with more spend rather than better alignment. If a company genuinely delighted customers at every interaction, that alone would drive growth. Marketing is often a blunt instrument deployed to prop up businesses with more fundamental issues, and the four Ps framework, used honestly, forces you to confront that.

Price is a marketing decision. How you price a product signals who it is for, how it compares to alternatives, and what kind of relationship you are trying to build with customers. Pricing strategy shapes perception as much as any campaign. BCG’s work on go-to-market pricing strategy makes the case that pricing decisions are inseparable from broader commercial strategy, and that getting them wrong undermines everything else you do in market.

Place is distribution. Where and how customers can access what you offer is a marketing decision. A product with the right positioning and the right price, available in the wrong channel, will underperform. This is particularly relevant in digital contexts, where the proliferation of channels creates the illusion of reach without the reality of access to the right audiences.

Promotion is the part most people call marketing. It is the smallest of the four Ps in terms of its leverage on business outcomes, and the one that gets the most attention and budget. That imbalance is worth examining in any organisation.

Marketing Is Not What Most Marketing Teams Do

This is not a criticism of marketing teams. It is an observation about how organisations are structured. Most marketing departments are responsible for communications: campaigns, content, social, email, paid media. These are legitimate and important activities. But they represent a fraction of what marketing, as a discipline, encompasses.

The decisions that most determine whether a business grows or stagnates, what to offer, to whom, at what price, through which channels, are often made by product teams, commercial teams, or the C-suite, with limited input from marketing. The result is that marketing teams are handed a brief and asked to communicate something that was decided without them. They are downstream of the decisions that matter most.

This is not inevitable. Companies that treat marketing as a strategic function rather than an execution function give marketing leaders a seat at the table when product, pricing, and distribution decisions are made. Those companies tend to have better alignment between what they offer and what the market wants, because the people responsible for understanding customers are involved in shaping the offer, not just communicating it.

When I was growing an agency from around 20 people to over 100, one of the clearest lessons was that internal alignment on what we were selling, to whom, and why, mattered more than any individual campaign. When the whole business understood the positioning, every client conversation, every proposal, every piece of work reinforced the same message. When that alignment broke down, no amount of marketing activity compensated for it.

Demand Creation Versus Demand Capture

One of the most important distinctions in marketing is between creating demand and capturing it. Most digital marketing, particularly performance marketing, is demand capture. It intercepts people who are already looking for something and converts them. This is valuable. It is also limited.

If everyone who was going to buy from you was already looking for you, demand capture would be sufficient. But most markets do not work that way. The majority of potential customers are not actively searching. They have a latent need, or a problem they have not yet connected to your category, or a habit with a competitor they have not been given a reason to change. Reaching those people requires demand creation: building awareness, shifting perception, making your category relevant to people who were not already in it.

Earlier in my career I overvalued lower-funnel performance metrics. The numbers were clean and the attribution was legible. What I came to understand, over time, is that much of what performance marketing gets credited for was going to happen anyway. You are measuring the last step of a experience, not the whole experience. The person who searches for your brand and converts was often already on their way. The harder and more important question is how you reach the person who was not yet looking.

Think of it this way. Someone who walks into a clothes shop and tries something on is far more likely to buy than someone who walks past. Performance marketing is brilliant at finding people already in the shop. But it does almost nothing to bring new people through the door. A complete definition of marketing has to include both, because a business that only captures existing demand will eventually run out of it.

Vidyard’s analysis of why go-to-market feels harder now touches on this tension. Markets are more saturated, attention is more fragmented, and the easy gains from demand capture are increasingly competed away. The businesses that grow in that environment are the ones that invest in creating demand, not just harvesting it.

The Customer Is Not a Data Point

Marketing is sometimes described as a data discipline now, and there is something to that. The availability of behavioural data, search data, and customer analytics has made it possible to understand audiences with a precision that was not available twenty years ago. But data describes behaviour. It does not explain it.

Knowing that a segment of customers has a high average order value tells you something useful. It does not tell you why they buy, what they are actually trying to achieve, what alternatives they considered, or what would make them buy more often. That kind of understanding requires qualitative research, direct conversation, and the kind of intellectual curiosity that data alone cannot replace.

I have judged the Effie Awards, which recognise marketing effectiveness rather than creative execution. The campaigns that consistently demonstrate real commercial impact share a common characteristic: a genuine understanding of the customer that goes beyond demographic data or behavioural segmentation. They understand what people actually care about, not just what they click on. That depth of understanding is harder to build than a dashboard, and more valuable.

Tools like Hotjar’s feedback and behaviour analytics can surface patterns in how users interact with digital experiences, which is useful. But the insight that changes a strategy usually comes from understanding the why behind the behaviour, not just the behaviour itself. Qualitative and quantitative research are complements, not substitutes.

Marketing Cannot Fix a Bad Product

This is the most uncomfortable part of defining marketing honestly. The discipline has limits, and the most important limit is that marketing cannot compensate for a product or service that does not meet customer needs well enough.

Marketing can accelerate adoption of a good product. It can build awareness for something genuinely valuable. It can shift perception and create preference in a competitive market. What it cannot do is sustainably grow a business built on an offer that disappoints the people who buy it. In that situation, marketing does not help. It speeds up the cycle of acquisition and churn, which is expensive and demoralising for everyone involved.

I have worked with businesses in turnaround situations where the instinct was to increase marketing spend to compensate for declining performance. In almost every case, the problem was not that not enough people knew about the product. The problem was that the people who knew about it were not choosing it, or were not coming back. More marketing spend in that context is like turning up the volume on a message nobody wants to hear.

The honest version of marketing strategy starts with an honest assessment of the product. Is it genuinely good? Does it solve a real problem better than alternatives? Are customers who buy it satisfied? If the answers to those questions are equivocal, that is where the work needs to happen before marketing can be effective.

Strategy Before Tactics: Why the Order Matters

One of the most persistent problems in marketing practice is the inversion of strategy and tactics. Businesses decide on channels, tools, and formats before they have clarity on who they are trying to reach, what they are trying to say, or what commercial outcome they are working toward. The result is a lot of activity that produces very little.

Strategy in marketing means making choices. Who are we for? What do we offer that is genuinely different or better? Where do we compete and where do we not? What does success look like and how will we know if we are achieving it? These questions are harder to answer than “which channels should we use?” and that is exactly why they get skipped.

The channel question is not unimportant. But it is downstream of the strategic questions. The right channel depends on who you are trying to reach and what you are trying to communicate. Without clarity on those things, channel selection is guesswork dressed up as planning. BCG’s work on go-to-market launch strategy illustrates how the sequencing of strategic decisions directly affects commercial outcomes, even in highly specialised categories like biopharma where the stakes are particularly high.

The businesses I have seen execute marketing most effectively tend to have unusual clarity about who they are and who they are for. That clarity does not come from a brand workshop or a positioning exercise done once and filed away. It comes from a genuine understanding of the market, the customer, and the competitive context, revisited regularly as those things change.

Growth Marketing and the Tool Proliferation Problem

“Growth marketing” or “growth hacking” emerged as a way of describing a more experimental, data-driven approach to marketing, particularly in the startup world. The ideas behind it are sound: test quickly, measure carefully, double down on what works. The problem is that the term has become attached to a set of tools and tactics rather than a way of thinking.

The growth marketing literature, including resources like Semrush’s overview of growth hacking tools, covers a wide range of platforms and techniques. These tools are genuinely useful in the right context. The risk is treating tool adoption as a substitute for strategic thinking. A business with a weak offer, unclear positioning, and a misunderstood audience will not grow because it adopts the right stack. It will produce more data about its failure, faster.

The growth mindset that actually produces results is one that asks hard questions about what is limiting growth, and then tests hypotheses to answer those questions. Sometimes the answer is a channel or a tool. More often it is something more fundamental: the audience definition, the value proposition, the product experience. Tools are useful when you know what question you are trying to answer. They are a distraction when you do not.

Creator-led marketing is a good example of a tactic that can be genuinely effective or completely wasteful depending on the strategic context. Later’s work on go-to-market campaigns with creators shows how influencer and creator partnerships can drive real commercial outcomes when they are built around a clear audience strategy. Without that foundation, creator campaigns produce content, not growth.

How to Build a Working Definition for Your Organisation

The academic definitions of marketing are fine as a starting point. They are not sufficient as an operating definition for a business trying to grow. What a working organisation needs is a definition specific enough to create clarity about what marketing is responsible for, what decisions it informs, and how its success will be measured.

A useful working definition of marketing for most businesses would include four elements. First, understanding: the ongoing process of knowing who your customers are, what they want, and how your offer compares to alternatives. Second, shaping: contributing to product, pricing, and distribution decisions based on that understanding. Third, communicating: making the right people aware of what you offer and why it is worth choosing. Fourth, measuring: tracking whether marketing activity is producing the commercial outcomes the business needs.

Notice that “communicating” is third on that list, not first. In most organisations, it is treated as first, last, and only. That is the structural problem that a better definition of marketing is designed to solve.

The accountability question is also worth addressing directly. If marketing is defined broadly enough to include product shaping and pricing input, then marketing needs to be accountable for commercial outcomes, not just campaign metrics. That is a more demanding standard, and it requires a different kind of marketing leadership: people who understand the business, not just the discipline.

There is more on how this connects to go-to-market planning and commercial strategy in the Go-To-Market and Growth Strategy hub, which covers the full range of decisions that determine whether a business can grow sustainably in competitive markets.

The Measurement Problem at the Heart of Marketing

One of the reasons marketing gets defined narrowly is that narrow marketing is easier to measure. Click-through rates, cost per acquisition, return on ad spend: these are clean numbers that can be reported in a dashboard and presented in a board meeting. The broader commercial impact of marketing, the effect on brand preference, on customer lifetime value, on the competitive position of the business, is harder to measure and therefore easier to ignore.

This creates a perverse incentive. Marketing teams optimise for what they can measure rather than what matters most. Over time, the things that matter most get less investment, because they are harder to justify in a quarterly review. Brand building, audience development, market education: these are the activities that create the conditions for sustainable growth, and they are chronically underinvested in relative to their commercial importance.

The answer is not to abandon measurement. It is to build a measurement framework that reflects the full scope of what marketing is supposed to achieve. That means combining short-term performance metrics with longer-term indicators of brand health, customer quality, and market position. It means being honest about attribution, which in most cases is far less precise than the tools suggest. And it means accepting that some of the most important marketing work will never produce a clean ROI number, and investing in it anyway.

Across more than 30 industries and hundreds of millions in managed ad spend, the pattern I have seen repeatedly is that the businesses with the most sophisticated measurement frameworks are not necessarily the ones with the best marketing outcomes. The businesses with the best outcomes tend to have the clearest understanding of what they are trying to achieve and the discipline to invest in it consistently, even when the short-term numbers are ambiguous.

What a Complete Definition of Marketing Produces

When a business defines marketing completely, something changes in how it operates. Marketing becomes a function with genuine strategic influence rather than a service department that executes briefs. Customer understanding informs product decisions. Pricing is treated as a commercial and perceptual lever, not just a finance calculation. Distribution choices are made with the audience in mind. Communications are built on a clear positioning rather than assembled from available assets.

This does not require a large marketing team or a significant budget. It requires clarity of thinking and the organisational will to give marketing the scope it needs to do its job properly. Small businesses with limited resources can define marketing completely and execute against that definition with focus. Large businesses with significant resources often define marketing narrowly and execute against that definition with volume, producing a lot of activity and not enough growth.

The companies that get this right share a characteristic I have noticed across industries and market conditions. They are relentlessly clear about who they are for. They do not try to be everything to everyone. They make deliberate choices about where to compete and where to walk away. And they treat marketing as the function responsible for maintaining that clarity as markets evolve, rather than as the team responsible for producing content about it.

That is what marketing is, properly defined. Not a department, not a set of channels, not a campaign calendar. A commercial function responsible for understanding the market, shaping the offer, and connecting the two in a way that produces sustainable growth. Everything else is a means to that end.
