Segmenting is the process of dividing a broad market into smaller groups of consumers who share similar needs, characteristics, or behaviors. The goal is simple, serve each group with the most relevant message and offer instead of forcing one generic message on everyone.
Quick summary
Segmenting means splitting a market into groups of similar consumers.
It is the first step of the STP framework, before targeting and positioning.
The four main types are demographic, geographic, psychographic, and behavioral.
Segmented and targeted campaigns drive 77% of email marketing ROI.
Segmented emails get 100.95% more clicks than non-segmented ones.
What Is Segmenting?
The key word is similar. No market is homogeneous. A student hunting for cheap coffee near campus and a manager looking for a meeting spot need different offers even though both buy coffee. Segmenting forces a business to acknowledge those differences and group consumers by the similarities that actually drive purchase decisions.
A good segment is measurable, reachable through existing channels, large enough to be profitable, and clearly different in how it responds to an offer.
Where Does Segmenting Sit in STP?
Segmenting is the S in Philip Kotler's STP framework, and the order never changes.
Stage | Question it answers | Output |
|---|---|---|
Segmenting | What groups make up this market? | A map of segments and their traits |
Targeting | Which groups are worth pursuing? | Priority segments |
Positioning | How should the brand be remembered by that segment? | Message and differentiation |
What Are the Types of Market Segmentation?
Type | Basis | Example variables |
|---|---|---|
Demographic | Who the consumer is | Age, gender, income, education, occupation |
Geographic | Where the consumer is | City, region, urban or rural, climate |
Psychographic | How the consumer thinks | Lifestyle, values, interests, social class |
Behavioral | How the consumer acts | Purchase frequency, loyalty, funnel stage, product usage |
In digital advertising, behavioral segmentation usually pays best because it sits closest to purchase intent. Someone who visited your product page twice is worth far more than someone who merely fits the demographic profile.

The doubled click rate is not about better emails. The content can be identical. Only the audience changes, the right message finally reaches people who care. Paid ads work the same way, identical budgets convert better when the audience is split correctly.
How Do You Segment a Market?
Start with the customer data you already have. Transactions, website analytics, and surveys are more honest than internal assumptions.
Pick the most relevant basis. Behavioral if you have the data, demographic and geographic if you are starting from zero.
Build a profile per segment. A name, a needs description, and a size estimate give the whole team a shared language.
Test each segment's response. Run small campaigns per segment and compare CTR, CPA, and conversion.
Review regularly. Segments drift as products and markets change, revisit at least quarterly.

How Does Segmenting Relate to Digital Ads?
Every modern ad platform is a segmentation machine. Custom audiences, lookalikes, and retargeting are just automated behavioral segmentation. Wasted ad spend almost always shares one root cause, a generic message forced to work for every segment at once. We cover how to read and optimize this in the complete performance marketing guide.
