What Market Segmentation is

Segmentation means splitting a big market into smaller groups with similar needs and behaviour. The point is to pick a segment you can win (not to serve everyone).

Common segmentation types

  • Demographic — age, income, job role
  • Geographic — country, city, region
  • Psychographic — values, lifestyle, attitudes
  • Behavioural — usage frequency, loyalty, price sensitivity
  • B2B firmographic — company size, sector, tech stack

STP: Segmentation → Targeting → Positioning

  1. Define possible segments
  2. Choose the best target segment (based on size, growth, access, willingness to pay)
  3. Position: “Why you” vs alternatives

How to choose a strong target segment

  • Clear pain + urgent need
  • Easy to reach (channels)
  • Willingness to pay
  • Low competition or weak alternatives
  • Strong fit with your capabilities
If you can’t describe your target segment in one sentence, your marketing will be expensive.

One-sentence segment test

“We help [specific customer] who struggle with [pain] by providing [solution] better than [alternative] because [differentiator].”

Market Segmentation

Split a market into meaningful groups, choose the best target, and create clear positioning — so you don’t waste time selling to “everyone”.

What it is
A structured way to break a market into groups with different needs and buying behaviour.
What you get
A target segment, ICP, positioning statement, and channel/message direction.
Where it fits
After Industry Analysis → before SWOT and go-to-market strategy.
Common trap: If you target everyone, your product becomes generic and your marketing becomes expensive.

What segmentation is (and what it is not)

Segmentation is dividing a market into groups that respond differently to an offer. The goal is to pick a segment where you can win: clear pain, reachable customers, ability to pay, and realistic competition.

Not segmentation: “People who like my idea” or “Businesses that need software”. That’s too vague.
Good segmentation: “UK salons with 3–10 staff, losing money from no-shows, currently using WhatsApp + paper diary.”
StrategyTools rule: Segmentation must end with a decision (target + positioning) and 5–10 actions.

Segmentation bases (ways to split a market)

You can segment in many ways, but the most useful in real strategy is: needs-based + behavioural. Other bases help you filter and target.

Demographic

Who they are (age, income, role, company size)

Examples
  • B2C: 18–25 students vs 35–50 parents
  • B2B: micro (1–9) vs SME (10–249) vs enterprise

Geographic

Where they are (country, region, city, climate, density)

Examples
  • UK London vs UK rural
  • EU countries with different regulation

Psychographic

What they believe/value (lifestyle, identity, motivations)

Examples
  • Premium buyers value status + design
  • Risk-averse buyers value trust + stability

Behavioural

How they behave (usage, loyalty, triggers, willingness to pay)

Examples
  • Heavy users vs occasional users
  • Discount hunters vs convenience buyers

Needs-based (best)

What outcome they want (job-to-be-done + pain + desired result)

Examples
  • Reduce admin time by 50%
  • Avoid compliance risk
  • Increase sales conversion
Best practice: Start with needs-based (outcomes) then add behavioural signals (usage, urgency, willingness to pay).

If it’s B2B: map the buying roles

In B2B, the segment is not only the company type — it’s also who inside the company influences purchase.

User
Uses it day-to-day and feels the pain.
Influencer
Recommends tools or shapes internal opinions.
Decision maker
Approves the decision (often management).
Economic buyer
Controls budget / signs contract.
Gatekeeper
Blocks access (IT, procurement, compliance).
Common B2B mistake: selling to the “user” but ignoring IT/procurement gatekeepers or the real budget owner.

ICP (Ideal Customer Profile): who you should target first

ICP is the “best first customer type”: urgent pain, reachable, able to pay, and likely to stay if you deliver outcomes.

Pain
Clear pain + urgency to solve now.
Budget
They can pay and see ROI.
Access
You can reach them with channels you can afford.
Fit
Your offer matches their workflow and context.
Retention
They will stay if you deliver outcomes.
Growth
Enough market size to scale.
Rule: Choose one primary ICP first. You can expand later.

How to do segmentation (practical workflow)

Use this workflow to build a segmentation model you can act on.

1) Define the market (boundaries)
Make sure you know which category you’re in and what alternatives customers use today.
2) Pick segmentation bases
Use needs-based + behavioural if possible; add demographic/geographic as supporting filters.
3) Build segment candidates (2–6)
Write each segment as a real group with a clear problem and buying context.
4) Score segments (attractiveness vs fit)
Use simple scoring to avoid emotional decisions. Choose the best target.
5) Choose target + positioning
Pick ONE primary segment. Write a positioning statement and messaging angles.
6) Validate with evidence
Use interviews, landing pages, ads, outreach, and pilots to confirm demand and willingness to pay.
Validation rule: Segmentation is a hypothesis until you confirm it with real interviews and conversion data.

Targeting: score segments (Attractiveness vs Fit)

Create 2–6 segment candidates, then score them 1–5 across the criteria below. This helps you pick a segment logically, not emotionally.

Market size
Is it big enough to grow?
Growth rate
Is demand increasing?
Urgency
Is the pain urgent?
Ability to pay
Do they have budget?
Reachability
Can you access them cheaply?
Competition
How crowded is this segment?
Switching cost
Will they stick?
Strategic fit
Does it match your strengths?
Tip: If two segments score similarly, choose the one with easier access (reachability) and stronger urgency.

Positioning: turn the segment choice into a clear message

Once you pick a target, write a positioning statement. This becomes your product decisions, landing page, and sales message.

Positioning template
For [target segment] who struggle with [problem], our [product/category] provides [main benefit/outcome]. Unlike [main alternative], we [key differentiator].
Rule: Positioning must be specific enough that the wrong customer says: “This is not for me.”

Common mistakes

Segmenting by “vibes”: No real criteria, no scoring, no evidence.
Too many segments: You end with 20 groups and still no decision.
Confusing personas with segments: A persona describes one person; a segment is a group with shared needs.
No validation: You assume willingness to pay without testing.
Final check: Your segmentation is good only if it reduces CAC, increases conversion, and improves retention.

Next steps

After segmentation, move to Internal Analysis (SWOT) and connect external opportunities to your strengths.
