also called market segmentation
Dividing a market into groups that behave or buy differently.
Splitting the market into groups worth treating differently.
What It Is
Segmentation is a Business item, filed under Audience. The canonical meaning is dividing a market into groups that behave or buy differently.
It is an idea you reason with rather than a deliverable you hand over, so two teams can both hold it correctly and still apply it differently. That definition is deliberately narrow — the narrowness is what makes it usable.
How It's Used
Segmentation earns its keep in commercial decisions, pricing conversations and how the business runs. It rarely travels alone — expect it next to Target Audience, Ideal Customer Profile and Audience Targeting. The practical test is whether a decision changes because of it.
Why It Matters
The cost of being vague about Segmentation shows up later, not today. When it is unclear, margin leaks in places nobody is looking. The businesses that treat it seriously spend less time redoing work.
Imagine a rule of thumb that helps you choose between options. Splitting the market into groups worth treating differently.
Termshift™
How the meaning shifts depending on who is using it, and where.
In agency and in-house rooms, Segmentation means exactly dividing a market into groups that behave or buy differently.
In plain conversation it comes out as splitting the market into groups worth treating differently.
The Bottom Line
Segmentation pays off when it is specific and costs you when it is not. Splitting the market into groups worth treating differently.
