Segmentation Snapshot

Cut the market by what buyers need or how they buy, score the segments on the same scale, and check that message, channel and money actually differ between them. A segmentation that changes no decision is overhead.

Segmentation is strong research, conceptually and as a method (Smith, 1956; Dolnicar, Grün & Leisch, 2018). The scoring scale, the weights and the strategic intents on this page are practice and rules of thumb, not research.

Use it when:

• You sell to more than one kind of customer and suspect that one message and one price are serving none of them well.
• You are setting next year's marketing or sales plan and need to decide where effort goes.
• Your team argues about which customers matter most and the argument rests on anecdotes.

Skip it when:

• You do not yet know who pays you today: start with 6.1 Who Are Our Customers.
• You already have a focus segment and need to understand its need in depth: use 6.4 Jobs-to-Be-Done Canvas.

Demand is not uniform. Buyers differ in ways that matter, and a firm can either push one offer onto the whole market or shape its offers around the real groups inside it; spotting those groups is where both choices start (Smith, 1956). The mechanism is fit. When message, price, channel and service match what one group wants, each unit of effort does more than when it is averaged across everyone. Few ideas in marketing are better established, and the methods for finding and checking segments are well developed (Dolnicar, Grün & Leisch, 2018).

The limits are practical. A segment earns its place only if it differs in need or behavior (not just in label), can be reached, is large enough to serve, and is treated differently in practice. That is why this page asks what you cut by, forces a rank, asks whether treatment and budget follow it, and ends with tests: segments drawn in a workshop are hypotheses until purchase data or interviews back them.

Tick the bases you could use, then pick the one that best predicts what people buy and why. Need and behavior usually give you more to act on than demographic labels.

Strong answer: "Primary variable: how often they reorder (behavioral). Why: our repeat buyers want delivery terms, one-off buyers want a low entry price, and the two need different offers." Not "company size, because it is in the CRM."

☐ Demographic (consumers: age band, life stage, household)

☐ Firmographic (businesses: industry, size, ownership)

☐ Geographic (region, urban or rural)

☐ Psychographic (attitudes, values, lifestyle)

☐ Behavioral (purchase frequency, usage, loyalty)

☐ Needs-based (the job or outcome they want)

☐ Value-based (what they are worth to you)

Primary variable and why it predicts buying:

Illustrative example: the business and all numbers are made up.

A family-owned workwear supplier in Denmark, about thirty staff, sells boots, clothing and safety gear. The sales manager and the owner fill in the page from last year's invoices.

Step 1: they cut by buying behavior: how often a customer reorders. Size had been the habit, but small and large builders behaved alike.

Step 2: (1) regular site buyers, construction firms ordering monthly, about half of revenue and more of the profit; (2) municipalities buying by annual tender, a quarter of revenue at thin margins; (3) one-off buyers, small trades ordering a few times a year online.

Step 3: regular buyers score highest and get Grow. Municipalities get Maintain: steady, but tenders are won on price. One-off buyers get Harvest.

Step 4: regular buyers get an account manager and fixed delivery days; municipalities a tender team with a price floor; one-off buyers the web shop only. The field sales time spent on one-off buyers moves to regular buyers.

Step 5: least sure that regular buyers value delivery over price. Test: offer fixed delivery days to ten of them and compare reorders after three months.

The finding that changed the plan: a third of field visits went to the segment ranked last.
