Jane Advertising: Why the Oldest Creative Principles Still Win
Jane advertising refers to a strategic approach that centres creative work on a specific, clearly defined audience rather than broadcasting to everyone and hoping something lands. It is the discipline of knowing exactly who you are talking to, what they care about, and how your message fits into their life, before you spend a single pound on media. The name is shorthand for audience-first thinking, and it is the foundation that separates marketing that compounds over time from marketing that simply burns budget.
It sounds obvious. Most marketers would say they already do this. In practice, most do not, and the gap between believing you know your audience and actually building creative and strategy around them is where most campaigns fall apart.
Key Takeaways
- Jane advertising is audience-first thinking applied at every stage of strategy and creative, not just in the brief.
- Most campaigns fail not because the creative is weak, but because the audience definition was too vague to give the creative anything real to work with.
- Knowing your audience means understanding their context, not just their demographics. Where they are in life shapes what they need to hear.
- Performance channels capture existing intent. Jane advertising builds the conditions that create intent in the first place.
- The brands that compound over time are the ones that consistently speak to a specific person, not the ones that try to appeal to everyone at once.

What Does Audience-First Actually Mean in Practice?
Early in my career I spent a lot of time in rooms where audience definition meant a demographic bracket and a broad psychographic. Women, 25-45, interested in lifestyle and wellness. That was considered a brief. We would build campaigns around it, produce creative, buy media, and then wonder why the work felt generic even when the execution was technically competent.
The problem was not the creative team. It was that “women 25-45 interested in wellness” is not a person. It is a category. You cannot write to a category. You cannot make a category feel something. You can only make a person feel something, and that requires being specific enough about who that person is that the creative has somewhere to go.
Jane advertising, in its most useful form, is the practice of building a single, fully realised human being at the centre of your strategy. Not a persona document that lives in a Confluence page and gets referenced once a quarter. A real working model of a real person: what they read, what they worry about at 11pm, what they told their friend last week about a brand they love or a purchase they regret. That specificity is what gives creative direction. It is what allows a strategist to say “this execution is right” or “this one misses” with confidence rather than gut feel.
If you are thinking about how this fits into a broader commercial framework, the Go-To-Market and Growth Strategy hub covers the structural decisions that sit around audience targeting, including how to sequence markets, prioritise channels, and build campaigns that are designed to grow rather than just activate.
Why Most Audience Thinking Stops Too Early
The first week I joined Cybercom, the founder handed me a whiteboard pen mid-brainstorm for a Guinness brief and walked out to a client meeting. The room was full of people who had been working on the account for months. My internal reaction was something close to panic. But the thing that got me through it was not bravado. It was forcing myself to ask the simplest possible question: who is actually drinking this, and what is happening in their life when they do?
That question cut through a lot of noise very quickly. Because when you get specific about the moment, the context, and the person, the creative possibilities narrow in a useful way. You stop trying to say everything and start trying to say the one thing that matters to that specific person at that specific time.
Most audience thinking stops at demographics because demographics are easy to measure and easy to report. Age, gender, income bracket, location. These are useful filters for media buying. They are not useful for creative strategy. The insight that actually drives good work is almost never demographic. It is contextual. It is about what is happening in someone’s life that makes your product relevant, or irrelevant, or something they have not even considered yet.
This is where market penetration thinking becomes relevant. Growing a brand is not just about converting more of the people who are already looking for you. It is about reaching people who are not yet in the market but could be, if you put the right message in front of them at the right moment. That requires knowing enough about those people to understand what that moment looks like.
The Performance Marketing Trap That Hides the Problem
I spent a significant chunk of my earlier career overvaluing lower-funnel performance. We had dashboards full of conversion data, cost-per-acquisition numbers that looked impressive in client presentations, and a general sense that we were being rigorous and commercial. What I understand now, having managed hundreds of millions in ad spend across more than 30 industries, is that a lot of what we were crediting performance channels for was going to happen anyway.
Someone who is already in market, already searching for your category, already comparing your product against competitors, is going to convert at a high rate regardless of whether you show them a perfectly optimised ad or a slightly less optimised one. You are not creating demand at that point. You are capturing it. And capturing demand is not the same as building a business.
The analogy I keep coming back to is a clothes shop. Someone who walks in and tries something on is many times more likely to buy than someone who walks past the window. But the window display is what gets them through the door. If you only measure what happens at the till, you will underinvest in the window and wonder why footfall is declining. Jane advertising is, in part, the discipline of investing in the window: reaching people before they are in market, building familiarity, and creating the conditions that make conversion possible later.
Forrester’s intelligent growth model makes a similar point about the relationship between acquisition and retention, and the danger of optimising too narrowly for short-term conversion at the expense of long-term brand equity. The brands that compound are the ones that invest upstream, not just at the point of purchase.
How Audience Specificity Changes Creative Output
When I was running the agency and we grew from around 20 people to over 100, one of the clearest markers of a campaign that was going to perform was how specific the creative brief was about the audience. Not specific in the sense of detailed demographic tables, but specific in the sense of: does everyone in this room have the same picture in their head of who we are talking to?
When the answer was yes, the creative was almost always better. Not because the team was more talented on those briefs, but because they had something real to react to. A real person has contradictions, preferences, blind spots, and moments. A demographic bracket has none of those things, and so the creative produced for a demographic bracket tends to be smooth and inoffensive and completely forgettable.
Jane advertising, at its best, produces work that feels like it was made for someone specific. The paradox is that work made for someone specific tends to resonate more broadly than work made for everyone. This is not a new observation. It is one of the oldest truths in advertising, and it keeps getting rediscovered because each generation of marketers has to learn it the hard way.
Creator-led campaigns illustrate this well. The ones that perform are almost always built around a specific creator speaking to a specific community, not a generic influencer broadcasting to a broad audience. The specificity of the relationship between creator and audience is the mechanism. Strip that out and you are left with expensive content that nobody trusts.
Where Jane Advertising Fits in a Go-To-Market Plan
A go-to-market plan without a clear audience definition is not a plan. It is a list of channels and a budget. The audience definition is the thing that makes every other decision coherent. Which channels you use, what you say, how you price, how you sequence markets, how you brief your creative team: all of these decisions are downstream of who you are talking to and what matters to them.
BCG’s work on go-to-market strategy consistently points to audience segmentation as the variable that separates high-performing commercial strategies from average ones. Not because segmentation is a magic lever, but because it forces the kind of specificity that makes everything else more precise. When you know who you are selling to and why they buy, pricing decisions become clearer, channel decisions become clearer, and the creative brief becomes something a team can actually use.
The mistake most businesses make is treating audience definition as a one-time exercise. You do it at the start of a planning cycle, it goes into a strategy deck, and then it gets quietly ignored as the year progresses and the pressure to deliver short-term numbers takes over. The brands that do this well treat audience understanding as a continuous practice, not a box to tick. They are constantly updating their picture of who their customer is, what has changed in their life, and what that means for how the brand should show up.
Growth loop thinking is useful here because it frames audience insight as something that feeds back into the product and the marketing continuously, rather than being a fixed input at the start of a campaign. The best brands are in a constant loop of learning, adjusting, and improving their picture of who they serve.
The Difference Between Knowing Your Audience and Assuming You Do
One of the more humbling experiences of my career was sitting in an Effie Awards judging session and watching campaigns that had clearly been built on assumptions fall apart under scrutiny. The work looked polished. The strategy documents were thorough. But when you asked “how do you know this is what your customer thinks?” the answer was almost always some version of “we believe” or “our experience suggests.” Not bad faith, just overconfidence in internal knowledge.
There is a version of audience definition that is really just the marketing team projecting their own preferences onto a fictional customer. It feels like insight because it is internally consistent and everyone in the room agrees with it. But it has not been tested against real people in any meaningful way. This is how you end up with campaigns that the agency and client both love and the actual customer ignores.
The antidote is not more research for its own sake. It is being honest about what you actually know versus what you are assuming, and being disciplined about closing the gap between the two. That might mean customer interviews, it might mean spending time in the channels where your audience actually spends time, it might mean looking at the data you already have with more honesty about what it does and does not tell you.
Growth hacking frameworks often skip this step entirely in favour of rapid experimentation, which can work in some contexts but tends to produce local optimisations rather than genuine strategic clarity. Knowing why something works is more valuable than knowing that it works, because the former compounds and the latter does not.
Building Creative Briefs That Actually Reflect the Audience
A brief that says “our audience is busy professionals who value quality” is not a brief. It is a description of approximately 40 million people. A brief that says “our audience is a 38-year-old operations director who is three years into a role she did not expect to stay in this long, who reads The Economist on Sunday mornings and feels vaguely guilty that she has not switched energy providers in four years” is a brief. You can write to that person. You can make her laugh, or make her feel seen, or make her feel slightly uncomfortable in a way that is useful.
The specificity is not a constraint. It is the creative permission. It tells the team what tone to use, what references will land, what problems are real versus theoretical, and what the brand needs to do to earn a place in that person’s attention. Without it, every creative decision becomes a negotiation between generic options rather than a genuine attempt to connect.
This is the core of what Jane advertising asks of a marketing team: not just to know who the audience is in abstract terms, but to be specific enough that the brief becomes a tool rather than a formality. The work that comes out of that kind of brief is almost always more interesting, more differentiated, and more effective than the work that comes out of a demographic description.
BCG’s research on evolving customer needs in financial services makes the point that even within a single demographic segment, the variation in what customers actually need and respond to is significant enough to require much more granular audience thinking than most brands apply. The same principle holds across almost every category.
When Audience-First Thinking Scales
One of the questions I get asked most often is how you maintain audience specificity as a brand grows and the customer base diversifies. The honest answer is that you do not maintain a single Jane. You develop multiple, clearly defined audience models that reflect the different people who buy from you and why, and you are disciplined about which one you are talking to in any given campaign or channel.
The mistake is trying to create a single audience definition that encompasses everyone, which inevitably produces something so broad it is useless. A better approach is to be explicit about the primary audience for each piece of work, and to accept that some of your customers will not be the target of every campaign. That is not a failure of reach. It is a sign of strategic discipline.
When I was turning around a loss-making agency, one of the first things I did was get clear on which clients we were actually good at serving and which ones we were taking on because we needed the revenue. The same logic applies to audience strategy. Being clear about who you are for, and who you are not primarily for, is not a limitation. It is what makes the positioning coherent and the creative work.
Vidyard’s research on GTM pipeline development points to audience clarity as one of the key differentiators between teams that consistently build pipeline and those that generate activity without commercial output. The underlying principle is the same: knowing who you are talking to, and what they need to hear, is the work. Everything else is execution.
If you want to go deeper on how audience strategy connects to channel selection, budget allocation, and campaign sequencing, the Go-To-Market and Growth Strategy hub pulls together the frameworks that make these decisions more systematic and less dependent on gut feel.
