The Advertiser’s Real Job Is Demand Creation, Not Demand Capture

An advertiser is any brand, business, or organisation that pays to place a message in front of an audience with the intent of driving awareness, consideration, or action. That definition sounds simple. In practice, most advertisers spend the majority of their budget on the last part of that sentence and wonder why growth stalls.

The advertiser’s real job is not to convert people who were already going to buy. It is to create demand where none existed, reach people who have not yet considered you, and build enough commercial weight that your brand is the obvious choice when the moment arrives. Most of the industry has drifted away from that, and the consequences are showing up in flat growth curves across category after category.

What Does an Advertiser Actually Do?

At the most functional level, an advertiser creates paid exposure for a product, service, or idea. They decide where to show up, what to say, to whom, and how often. They manage budgets, evaluate channels, and report on outcomes. That is the operational reality of advertising.

But the strategic reality is different. The advertiser’s role in a business is to grow the pool of people who know about, want, and will eventually buy what the business sells. That is a fundamentally different framing from “run ads that convert.” One is a growth function. The other is a harvesting function. Both matter. But they are not the same thing, and conflating them is one of the most expensive mistakes an advertiser can make.

I spent a good portion of my earlier career over-indexing on the harvesting side. Performance marketing was where the measurable outcomes lived, and measurable outcomes were what clients wanted to see. It took me longer than I would like to admit to recognise that much of what we were crediting to performance was going to happen anyway. The customer had already decided. We were just the last door they walked through before buying. We were collecting intent, not creating it.

Think about a clothes shop. Someone who tries something on is far more likely to buy than someone who walks past the window. But getting people through the door in the first place, that is the job advertising was always supposed to do. If you only optimise for the fitting room, you run out of people to convert.

Why Demand Capture Is Not a Growth Strategy

Performance marketing channels are built to capture existing demand efficiently. Search advertising intercepts people who are already looking. Retargeting reaches people who have already visited. Shopping ads serve people who are already comparing. These are genuinely useful tools. The problem is not the tools. The problem is treating them as the whole strategy.

When an advertiser allocates the majority of their budget to capturing existing intent, they are competing for a fixed pool of demand. They can get better at winning that competition, but they cannot make the pool bigger. Growth, real category-expanding growth, comes from reaching people who are not yet in the market and making your brand the one they think of when they eventually enter it.

This is not a new idea. Forrester’s work on intelligent growth models has consistently pointed to the distinction between defending existing customers and acquiring genuinely new ones as a core strategic tension for marketers. The advertisers who grow over time are the ones who invest in both, with intention, rather than defaulting to whatever is easiest to measure.

The challenge is that demand creation is harder to attribute. You cannot draw a straight line from a brand awareness campaign to a sale that happens six months later. So finance teams discount it. Performance teams ignore it. And slowly, the advertiser’s reach contracts until they are only talking to people who were already listening.

If you are thinking about how this connects to broader go-to-market decisions, including how to sequence investment across channels and audiences, the Go-To-Market and Growth Strategy hub covers that territory in more depth.

The Advertiser as a Commercial Function, Not a Creative One

There is a version of advertising that exists to win awards. There is another version that exists to grow businesses. The best work does both. But when they come into conflict, the commercially grounded advertiser knows which one to prioritise.

I have judged the Effie Awards, which are specifically designed to recognise marketing effectiveness rather than creative craft. What struck me was how often the winning work was not the flashiest or the most talked-about in the industry. It was the work that understood what the business needed, built a strategy around that, and executed with enough consistency to actually move the needle. The creative was in service of the commercial goal, not the other way around.

That orientation, commercial first, is what separates an advertiser who is genuinely useful to a business from one who produces impressive-looking activity that does not compound into anything. It requires understanding the P&L, not just the media plan. It requires knowing which metrics are proxies for business outcomes and which are just metrics. And it requires the confidence to push back when the brief is chasing the wrong objective.

Understanding market penetration as a concept is genuinely useful here. Penetration-led growth, reaching more buyers rather than extracting more from existing ones, is the mechanism by which advertising creates commercial value at scale. Advertisers who understand this think differently about who they are trying to reach and why.

How Advertisers Should Think About Audience

One of the most consistent errors I see is advertisers defining their audience too narrowly. They target their existing customers, their website visitors, their CRM list. These are all legitimate audiences for certain objectives. But they are not a growth audience. They are a retention audience.

Growth comes from the people who do not know you yet. The people who buy from a competitor out of habit. The people who have not thought about the category at all. These are harder to reach, harder to measure, and harder to convince. They are also the only source of new revenue that is not already on your books.

When I was building the team at iProspect, we grew from around 20 people to over 100 across a few years. A meaningful part of that growth came from winning clients who had never considered us, not from upselling the ones we already had. We had to go out and find them, earn their attention, and make a case. That is demand creation applied to a services business. The same principle holds for any advertiser in any category.

The practical implication is that audience strategy should include a deliberate allocation to new-to-brand reach, not just retargeting and lookalikes built from existing buyers. Lookalikes are useful, but they are still modelled on people who already converted. At some point, you need to go further out and talk to people who look nothing like your current customers but might become your next ones.

Channel Strategy and the Advertiser’s Allocation Problem

Every advertiser faces an allocation problem. There are more channels than budget, more audiences than time, and more opinions about what works than there are data points to settle the debate. The way most advertisers resolve this is by defaulting to whatever worked last quarter. That is understandable. It is also how growth plateaus.

A more useful frame is to think about channel allocation in terms of what job each channel is doing. Some channels are good at reaching new people at scale. Some are good at maintaining salience with people who already know you. Some are good at converting people who are already in market. An effective advertiser uses all three, in proportions that reflect the business’s growth priorities, not just the channel’s measurability.

The reasons go-to-market feels harder now than it did five years ago are partly structural. Audiences are more fragmented. Attention is shorter. Signal loss from privacy changes has made attribution less reliable. But the fundamentals of what an advertiser is trying to do have not changed. Reach the right people, with the right message, at the right frequency, and do it consistently enough that the brand builds weight over time.

Creator-led content has become a meaningful part of how some advertisers reach new audiences, particularly in categories where trust and authenticity carry weight. Going to market with creators is not a replacement for paid media strategy, but it is a legitimate channel for reaching audiences that paid media alone cannot efficiently access. The advertiser who dismisses it entirely is leaving reach on the table.

Measurement and the Attribution Trap

Attribution is the advertiser’s most useful and most misleading tool simultaneously. It is useful because it tells you something about which touchpoints are present in the path to conversion. It is misleading because it tends to reward the last touchpoint disproportionately and ignore everything that built the conditions for conversion in the first place.

I have sat in enough post-campaign reviews to know how this plays out. The brand campaign runs. A few weeks later, search volume goes up. The performance team reports a great month. The brand campaign gets cut because it is hard to attribute. Search volume gradually normalises. The performance team has a harder quarter. Everyone wonders what changed.

What changed is that the advertiser stopped doing the work that created demand and kept doing the work that captured it. The pipeline dried up because nobody was filling it.

Good measurement for an advertiser is not about finding the most granular attribution model. It is about tracking the right mix of leading and lagging indicators. Brand health metrics, share of search, new-to-brand customer rates, category penetration over time. These are slower and less satisfying than last-click ROAS, but they are more honest about what advertising is actually doing to the business.

BCG’s work on go-to-market strategy highlights how pricing and market positioning decisions interact with growth outcomes in ways that simple conversion metrics cannot capture. The advertiser who only looks at conversion data is missing the structural context that explains why those conversions are happening or not happening.

The Advertiser’s Relationship With Creative

Creative quality matters more than most performance-focused advertisers want to believe. Not because great creative is inherently valuable, but because poor creative wastes reach. You can buy the right audience at the right moment and still fail to earn their attention if the work is forgettable.

Early in my career, I was at Cybercom during a Guinness brainstorm. The founder had to step out for a client meeting and handed me the whiteboard pen as he left the room. I remember the internal reaction clearly: this is going to be difficult. Not because I did not have ideas, but because the room was full of people who had been thinking about Guinness far longer than I had. The lesson I took from that session was not about the ideas themselves. It was about the discipline of staying in the problem rather than reaching for the first comfortable answer. Good creative comes from that discipline. It comes from staying with the brief long enough to find something that is actually true about the brand and the audience, rather than settling for something that merely fills the space.

For advertisers, the implication is that briefing matters. A weak brief produces work that looks fine but does nothing. A strong brief, one that is specific about the audience, the objective, the insight, and the role of the creative in the broader strategy, gives creative teams something to push against. That tension is where good work comes from.

Scaling Advertising Without Losing Effectiveness

One of the less-discussed challenges for advertisers is what happens when you scale. More budget, more channels, more markets, more stakeholders. The natural tendency is to add complexity: more targeting layers, more creative variants, more reporting dashboards. And effectiveness often goes down, not up, because nobody has a clear view of what is actually working anymore.

BCG’s research on scaling up agile operations is instructive here, even if its primary focus is organisational rather than marketing. The principle of maintaining clarity of purpose and decision-making speed as you scale applies directly to advertising. The advertisers who scale well are the ones who resist the temptation to add complexity and instead build simple, repeatable systems that can be executed consistently across markets and teams.

When I was managing significant ad spend across multiple markets and industries, the advertisers who struggled were rarely the ones with the smallest budgets. They were the ones with the most complicated internal processes. Approval chains that killed timeliness. Committees that diluted creative decisions. Measurement frameworks so elaborate that nobody trusted the outputs. Simplicity at scale is genuinely hard, but it is the thing that keeps advertising effective as the operation grows.

What Separates Effective Advertisers From Busy Ones

There is a version of advertising that generates a lot of activity: campaigns launching, budgets spending, reports being produced, meetings being held. And there is a version that generates commercial outcomes. These overlap more than they diverge in the best organisations. In mediocre ones, the activity becomes the point.

Effective advertisers are relentlessly focused on what the business actually needs. Not what the channel recommends. Not what the agency proposes. Not what won an award in a different category. What this business, in this market, with this product, needs to do to grow. That focus sounds obvious. It is surprisingly rare.

It requires the advertiser to have a genuine understanding of the business model, the competitive landscape, the customer’s decision process, and the brand’s current position in the market. It requires them to be honest about what advertising can and cannot do. And it requires them to make difficult choices about where to focus rather than trying to be everywhere at once.

Audience behaviour data, whether from tools like Hotjar or broader analytics platforms, can inform those choices. But the data is a perspective on reality, not reality itself. The effective advertiser uses it to sharpen their thinking, not to replace it.

More on how these decisions connect to broader commercial strategy, including how to think about sequencing investment across growth phases, is covered in the Go-To-Market and Growth Strategy hub.
