It seems intuitively like a company should want to appeal to as many potential customers as possible. In practice, marketing built around trying to please everyone tends to end up appealing strongly to no one, since different customers want genuinely different things and a message vague enough to suit everyone rarely resonates deeply with anyone. Segmentation, Targeting, and Positioning — STP — is the standard three-step framework marketers use to deliberately narrow that focus instead, and it's built specifically to prevent a company from trying to be everything to everyone.
Segmentation: the market isn't one thing
Segmentation is the process of dividing a broad market into smaller groups of customers who share meaningfully similar needs, behaviours, or characteristics — by demographics (age, income), by psychographics (values, lifestyle), by behaviour (usage patterns, brand loyalty), or by some combination of these. The underlying premise is that a market rarely behaves as a single uniform mass; it's actually composed of distinct groups with genuinely different priorities, and treating them as identical means a product or message optimised for one segment may land poorly with another.
Targeting picks a fight, and positioning picks the story
Once a market has been segmented, targeting is the decision about which of those segments to actually pursue, given a company's resources, competitive strengths, and the segment's own attractiveness (its size, growth, and profitability potential). Chasing every segment at once usually spreads a company's limited resources too thin to compete effectively in any of them, so targeting deliberately narrows focus to the segments a company is genuinely best positioned to win. Positioning is the final step: deciding, and then actively shaping through messaging and product design, exactly what distinct place a brand should occupy in the targeted customers' minds relative to competitors — not what the product objectively is, but what specific idea or benefit it should be associated with when a targeted customer thinks about that category at all. Together, the three steps convert a vague ambition to "reach customers" into a specific, defensible strategic choice about exactly who to chase and what story to tell them.
What we're still unsure about
STP is a long-standing, widely taught marketing framework, and its core logic — narrower focus tends to produce stronger resonance than broad, generic appeal — is well supported by decades of marketing practice. What remains more a matter of situational judgement than settled formula is exactly how finely to segment a given market and how many segments to target simultaneously: overly narrow segmentation can leave a company chasing markets too small to be commercially viable, while overly broad segmentation reintroduces the exact diffusion problem STP was designed to solve, and finding the right granularity for a specific product and market genuinely depends on circumstances the framework itself doesn't specify.
