STP Marketing (STP)

Originated by Philip Kotler in 1969

STP is the strategic backbone most campaigns are missing. Before you write a word of copy or pick a channel, you need to know who you're talking to, which slice of them you're actually serving, and what you want them to believe about you.

Most brands don’t have a marketing problem. They have a targeting problem dressed up as a marketing problem. The campaign underperforms, the creative gets blamed, and six months later a new agency produces a new campaign with the same unfocused brief. The cycle repeats.

STP breaks that cycle by demanding three decisions before any execution starts: who exists in your market, which group you’re actually serving, and what you need them to believe about you relative to everything else they could choose. Get those three things right and almost any competent execution will work. Get them wrong and brilliant creative will still miss.

What the Framework Actually Does

STP is a sequence, not a checklist. Each step feeds the next.

Segmentation is the exercise of mapping the market. You’re looking for meaningful differences between groups of potential customers, differences that actually affect what they need, how they decide, and what they value. The four classic lenses are demographic (age, income, geography), psychographic (values, lifestyle, attitudes), behavioral (purchase frequency, usage patterns, loyalty), and needs-based (the specific problem they’re trying to solve). Most useful segmentation combines more than one lens. “Women aged 35 to 55 who feel underrepresented in mainstream beauty advertising” is a more actionable segment than “women aged 35 to 55.”

Targeting is where you make a real choice. You evaluate each segment you’ve identified against criteria: How big is it? Is it growing or shrinking? Can you reach it efficiently? Does your product genuinely serve it better than alternatives? Do you have the resources to compete here? The temptation is to say “we’ll target everyone” or to pick the biggest segment by default. The discipline is to pick the segment where you have a genuine advantage and a credible right to win.

Positioning is the output of the first two steps, not a standalone exercise. Once you know your target, you define: what you want them to believe about you, what alternatives they’re comparing you against, and what evidence supports your claim. The classic positioning statement structure (“For [target], [brand] is the [category] that [key benefit] because [reason to believe]”) is formulaic but useful because it forces specificity. Vague positioning sounds like strategy and functions like noise.

The Origin

Kotler formalized STP in his landmark textbook work beginning in the late 1960s, drawing on earlier thinking from Wendell Smith who had distinguished between market segmentation and product differentiation in the 1950s. What Kotler contributed was the integration: the idea that segmentation only has value if it leads to deliberate targeting, and that targeting only has value if it drives a clear positioning strategy.

The framework became the organizing logic of modern marketing strategy through the 1970s and 1980s, as consumer goods companies realized that mass marketing was losing effectiveness and that serving distinct segments with tailored value propositions outperformed one-size-fits-all approaches. It has been refined and extended since, but the core sequence hasn’t changed.

How to Apply It

Start with segmentation research that goes beyond demographics. Survey your current customers and ask why they chose you, what alternatives they considered, and what job they were trying to get done. Interview lost customers. Look at your product reviews and your competitors’ product reviews. The language people use to describe frustration often reveals underserved needs that define real segments.

Map what you find into a segmentation matrix. Label each group and describe them in behavioral and attitudinal terms, not just demographic ones. Estimate rough size and growth trajectory for each.

Then evaluate. For each segment, score it against these four questions: Is it large enough to be worth pursuing? Are your product and capabilities a genuine fit? Can you reach this group efficiently through channels you have access to? Is it defensible, meaning can you build a position here that competitors won’t easily replicate?

Pick your primary target. This doesn’t mean ignoring other segments, but it means one segment shapes your core positioning, messaging, and resource allocation.

From there, build your positioning by identifying what makes you different and meaningful to that specific group. The difference has to be real (you can actually deliver it), relevant (the target cares about it), and distinct (no one else is credibly claiming it). Write the positioning statement. Then test whether your current product, pricing, channels, and messaging actually deliver it.

A Real Example

Dove’s Real Beauty campaign, launched in 2004, is a textbook STP case that still gets discussed because it worked so cleanly.

The segmentation insight: Dove’s parent company Unilever commissioned research showing that the vast majority of women didn’t consider themselves beautiful. The mainstream beauty market was segmented around aspiration toward a narrow, heavily retouched standard. An underserved segment existed: women who felt excluded by that standard and who would respond to a brand that reflected them honestly.

The targeting choice: Rather than chasing the same aspirational segment that every other beauty brand was fighting for, Dove deliberately targeted this underserved group: women who were skeptical of the industry’s ideals and hungry for something more authentic.

The positioning: Dove would be the beauty brand that celebrated real women rather than manufactured perfection. The tagline, creative, and product claims all aligned to deliver that single idea. This wasn’t just a campaign line; it influenced product formulations, pack design, and where the brand advertised.

The results were significant. Dove grew from a functional soap brand into one of the world’s most recognized beauty brands, and the positioning has anchored the brand’s work for two decades since. The key was the courage to not target everyone. The campaign was meaningless to people who aspired to conventional beauty standards, and Dove was fine with that.

When the Framework Falls Short

STP assumes you can define your segments clearly and that those segments will stay stable long enough to build a strategy around them. Neither assumption always holds.

Markets shift. New competitors create new category definitions. Consumer values evolve. The segment that looked attractive in your research may be smaller or more crowded by the time your campaign runs. The framework gives you a snapshot; the market keeps moving.

Segmentation exercises also carry the risk of confirmation bias. The segments you identify reflect the questions you asked and the data you collected. Truly disruptive opportunities often live in segments that existing market research doesn’t surface, either because researchers didn’t think to look or because the segment didn’t yet have language to describe its own need. Jobs to Be Done thinking can be a useful complement here, starting from what people are trying to accomplish rather than who they are.

There’s also an execution gap. Many brands complete a rigorous STP process, produce a beautifully written positioning statement, and then file it in a strategy deck that never sees daylight. Positioning is only real if it shapes what the product actually does, how it’s priced, where it’s sold, and how it’s communicated. A positioning statement that lives only in a presentation has zero value.

When to Use It (and When to Reach for Something Else)

STP is most valuable at the strategic inflection points: a new product launch, a repositioning effort, an entry into a new market, or a moment when your brand has lost clarity about who it’s for. It’s a pre-campaign framework, not a campaign framework. You run STP before you brief the creative team, not alongside them.

It’s also useful when you’re allocating a limited budget across multiple potential audiences. Running the targeting evaluation forces an honest conversation about where you have the right to win versus where you’re just hoping.

The Avis “We Try Harder” positioning is worth studying here. Avis made a deliberate choice to position against its own second-place status in the car rental market. That required clear segmentation (business travelers who valued service and accountability), precise targeting (the customer who Hertz was serving complacently), and a positioning claim that was differentiated, evidence-backed, and genuinely distinct. The result was one of the most durable brand positions in advertising history.

When the market is moving too fast for traditional segmentation research to keep up, or when you’re in a category so new that customers don’t yet know what segments exist, reach for more exploratory tools. Scenario planning and Jobs to Be Done interviews can generate the raw insight that STP then helps you structure. Use them together rather than treating STP as the only input.
