What Is Market Segmentation?

Market segmentation is dividing a market into groups with distinct needs, so each can be served and addressed differently.

In plain English

The point of segmenting is to find groups that behave differently, not groups that look different. Demographic segments are easy to build and frequently useless, because age rarely predicts what someone buys.

The bases that predict behaviour are need, situation and what the customer is trying to achieve. Two people in entirely different demographics with the same problem behave more alike than two neighbours with different problems.

What to know

By need or situation
What they are trying to solve, which predicts behaviour.
By behaviour
What they have actually done: purchase history, usage, frequency.
Demographics last
Useful for reach, weak for prediction.
Few segments
Two or three you actually serve differently beats eight on paper.

Why it matters

Segmentation earns its cost only when something changes because of it: different messaging, different offer, different channel. A segmentation model nobody acts on is an expensive diagram.

Common mistakes

×Segmenting by demographics because the data is available.
×Creating segments nobody serves differently.
×Too many segments to resource.
×Segmenting once and never revisiting it.

FAQs

How many segments should I have?

As many as you can genuinely serve differently. For most businesses, two or three.

What is the best basis?

Need and situation. They predict behaviour better than any demographic.
