The Market Segmentation Process: Steps and Criteria for Success

Not every product is for everyone – and the most successful brands know exactly who they’re talking to. That precision doesn’t happen by accident. It is the result of a structured, deliberate process called market segmentation: the systematic approach of dividing a broad, diverse market into smaller groups of consumers who share similar needs, characteristics, or behaviours. But simply slicing a market into groups isn’t enough. Those groups need to pass a set of rigorous criteria before any meaningful marketing strategy can be built around them. This post walks through the key steps of the segmentation process and the criteria that determine whether a segment is actually worth pursuing.

Step 1: Market research and data collection

The segmentation journey begins with research – and a lot of it. Effective market segmentation starts with a comprehensive understanding of the broader market, using both primary methods such as surveys, interviews, and focus groups, and secondary methods such as industry reports, competitor analyses, and existing sales data. Internal sources like CRM systems and customer feedback are equally valuable, as are external sources such as government publications and market research reports.

In India’s fast-moving consumer goods (FMCG) sector, for instance, a company launching a new beverage wouldn’t assume what consumers want – it would survey people across different states to understand preferences in flavour, packaging size, and price sensitivity. These data points are the raw material from which meaningful segments are eventually built. In today’s data-driven environment, relying on intuition alone is a significant risk. The research phase ensures that every subsequent decision is grounded in evidence, not guesswork.

Step 2: Identifying segmentation variables

Once sufficient data has been collected, the next step is to choose the variables – or criteria – by which the market will be divided. Segmentation variables are typically drawn from four broad bases: demographic, geographic, psychographic, and behavioural factors.

The four main segmentation bases

Demographic segmentation uses measurable characteristics like age, gender, income, education, and occupation. It is one of the most commonly used bases because the data is relatively easy to obtain and quantify. Geographic segmentation divides the market by location – region, city size, climate, or urban versus rural settings. A company marketing raincoats, for example, will logically focus on regions with higher rainfall.

Psychographic segmentation goes deeper, grouping people by lifestyle, values, personality traits, and aspirations. It’s particularly useful when demographic data alone doesn’t explain why consumers make the choices they do. Behavioural segmentation, meanwhile, divides the market based on consumer behaviour – including purchasing habits, usage patterns, brand loyalty, and benefits sought. It is especially useful for products where actual buying behaviour is a stronger predictor of future purchase than who the buyer is.

In practice, a firm will often use multiple segmentation bases simultaneously, combining them to get a fuller picture of its customers and to create real value for them. A skincare brand, for example, might layer age, gender, skin type, and purchase frequency together to build genuinely distinct consumer groups.

Step 3: Developing profiles of segments

Identifying segments is only half the work. The next step is to give each segment a detailed, vivid profile. After segmenting the market, evaluating each segment’s specific needs is important – this involves understanding what drives purchasing decisions, the pain points consumers experience, and the aspirations they hold.

These profiles go beyond raw statistics. They typically describe the segment’s average income, key motivations, typical lifestyle, brand attitudes, and preferred communication channels. Consider a skincare brand that has identified “young urban professionals” as one of its key segments. A useful profile of this group wouldn’t just say “aged 22-35, urban.” It would note that this group values convenience, is willing to pay a premium for science-backed ingredients, shops primarily online, and responds to influencer recommendations. This kind of specificity is what allows marketing teams to craft messaging that feels personal and relevant rather than generic. Segment profiles help bridge the gap between raw data and targeted, creative communication.

Criteria for effective segmentation

Here is a critical reality: just because you can divide a market into groups doesn’t mean those groups are useful. You could technically segment consumers into “people who prefer odd numbers” and “people who prefer even numbers” – but that would be meaningless for almost any business. For segmentation to be effective and successful, segments must meet a specific set of criteria, often summarised by the acronym ADAMS: Accessible, Differentiable, Actionable, Measurable, and Substantial. Let’s unpack each one.

Criterion 1: Measurable and accessible

Measurability means that the size, purchasing power, and key characteristics of a segment can be accurately quantified. The size and purchasing power profiles of a market segment must be measurable, meaning there is quantifiable data available about it. Without this, a business cannot make a rational decision about whether the segment is worth pursuing. Market research tools – from consumer surveys to government statistics to proprietary analytics platforms – are the primary means of achieving this measurability.

Accessibility asks a different but equally important question: can the segment actually be reached? A market segment should be accessible – meaning the organisation has the capabilities and budget to reach that segment through the right channels, whether outdoor advertising, social media, TV, or print. An FMCG company may identify a substantial segment of rural consumers in India, but if its distribution network doesn’t extend to those areas, and its advertising budget doesn’t cover regional language media, that segment is effectively inaccessible – at least for now.

Criterion 2: Substantial and differentiable

Substantiality is about profitability and scale. A segment must be large or profitable enough to justify the time, money, and effort of developing a separate marketing strategy for it. A segment of 10,000 customers might be substantial for a small local business but insignificant for a global tech giant. Importantly, substantiality isn’t just about current size – it also considers future growth potential. The early electric vehicle market, for instance, was small in absolute numbers but substantial because of its rapid growth trajectory and the high purchasing power of early adopters.

Differentiability is the criterion that ensures segments are actually distinct from each other. In an ideal world, a market segment should be internally homogeneous – consumers within it share similar preferences – but externally heterogeneous, meaning different segments are clearly distinct from each other. If two groups respond identically to the same marketing message, pricing change, or product feature, they are not genuinely different segments. For example, if teenagers and working adults react in exactly the same way to a soft drink advertisement, there is no meaningful differentiation between them as segments, and there is no strategic advantage to treating them separately.

Criterion 3: Actionable segments

The final – and arguably most critical – criterion is actionability. A segment is actionable when the company has the resources, capabilities, and expertise to design and execute a distinct marketing programme for it. An actionable segment is one for which the firm can craft and deliver a distinctive marketing programme; if the capacity to differentiate offerings is lacking, the segment is not actionable in practice.

Consider a local bakery that identifies a growing customer base interested in gluten-free and vegan pastries. This segment may be measurable, substantial, and differentiable – but if the bakery has a small kitchen with no dedicated gluten-free preparation area, no trained vegan bakers, and no budget for specialist ingredients, this segment is not actionable for them right now. Pursuing it without the necessary capabilities would likely result in a poor product, damaged reputation, and wasted resources. Actionability is what separates a viable segment from an aspirational one – it is the bridge between strategic insight and real-world execution.

Why the process and criteria must work together

The three steps and the segmentation criteria are not independent of each other – they function as a connected system. The research phase (Step 1) feeds the quality of variable selection (Step 2), which shapes the richness of segment profiles (Step 3). The criteria then act as a filter: once segments are profiled, each one is evaluated against measurability, accessibility, substantiality, differentiability, and actionability before any targeting decision is made.

Asking the right questions during research and prioritising ruthlessly during evaluation are what ensure a segmentation strategy achieves business objectives and drives long-term growth. Brands that skip this rigour often end up with segments that sound good in a presentation but fail in the market – either because the group is too small to be profitable, too scattered to reach efficiently, or too similar to adjacent groups to warrant a distinct strategy.

When done well, market segmentation is not just a marketing exercise – it is an act of precision. Actionability is the crux of effective segmentation criteria and of the overall strategy; without actionable insights, a brand is unable to reach and affect its desired audience, thus wasting time, resources, and energy. The entire process – from the first survey to the final segment profile – is ultimately about making sure that resources go where they will generate the most return, and that consumers receive a product and message that genuinely speaks to their needs.

What do you think? If you were launching a new health food product in a price-sensitive market like India, which segmentation variable – demographic, psychographic, geographic, or behavioural – would you prioritise first, and why? And when a company identifies a highly attractive segment but lacks the internal capabilities to serve it, should it invest in building those capabilities or walk away from the opportunity?
