Evaluating Market Segments
After dividing a broad market into smaller customer groups, a business must decide which segments are worth pursuing. Not every segment offers the same level of opportunity. Some may be too small, too competitive, difficult to reach, or poorly aligned with the company's resources.
Evaluating market segments helps managers compare opportunities objectively and select segments that offer the best balance of growth, profitability, accessibility, and strategic fit.
Learning Objectives
- Understand why market segments must be evaluated.
- Identify the main criteria used to assess market segments.
- Measure segment size, growth, and profitability.
- Evaluate accessibility and competitive intensity.
- Assess strategic fit and organizational capability.
- Use a segment evaluation matrix for decision-making.
Why Evaluate Market Segments?
Market segmentation identifies different customer groups, but evaluation determines which groups are commercially attractive.
A business evaluates market segments to:
- Prioritize the strongest opportunities.
- Avoid wasting marketing resources.
- Reduce market-entry risk.
- Improve sales and profitability.
- Align marketing decisions with company capabilities.
- Develop realistic targeting strategies.
Main Criteria for Evaluating Market Segments
The most important evaluation criteria include:
- Segment size.
- Growth potential.
- Profitability.
- Accessibility.
- Measurability.
- Competitive intensity.
- Strategic fit.
- Customer stability.
- Risk level.
- Long-term value.
1. Segment Size
Segment size refers to the number of potential customers and the total sales value available within a segment.
A segment should be large enough to justify the cost of serving it.
Questions to Consider
- How many customers belong to the segment?
- What is the estimated annual demand?
- How much does the average customer spend?
- Can the segment support long-term business operations?
Example: A company may identify a highly specialized customer group, but if only a few customers exist, the segment may not generate sufficient revenue.
2. Growth Potential
Growth potential measures whether a segment is likely to expand over time.
A small segment may still be attractive if it is growing rapidly.
Indicators of Growth
- Increasing customer demand.
- Population growth.
- Technology adoption.
- Changing lifestyles.
- Rising income levels.
- Favorable economic trends.
Example: The electric vehicle market was once relatively small, but strong growth made it attractive to automotive companies.
3. Profitability
Profitability measures whether a segment can generate sufficient financial returns after considering all costs.
A large segment is not automatically profitable. High competition, expensive customer acquisition, or low margins can reduce its attractiveness.
Profitability Factors
- Expected sales revenue.
- Average order value.
- Customer acquisition cost.
- Distribution expenses.
- Promotional expenses.
- Customer service costs.
- Expected profit margin.
A simple profitability estimate may be expressed as:
Estimated Profit = Expected Revenue − Total Costs
4. Accessibility
Accessibility refers to how easily a company can reach, communicate with, and serve customers in a segment.
Accessibility Questions
- Can the segment be reached through suitable media channels?
- Can products be distributed effectively?
- Is the segment geographically reachable?
- Can customer data be obtained legally and ethically?
- Does the company have suitable sales and support channels?
A segment may be attractive in size and profitability but unsuitable if the company cannot reach or serve it efficiently.
5. Measurability
A market segment must be measurable. The company should be able to estimate its size, purchasing power, characteristics, and behavior.
Useful Information Includes
- Number of potential customers.
- Income and spending patterns.
- Purchase frequency.
- Product preferences.
- Location.
- Media usage.
Segments based on vague or unobservable characteristics are difficult to target effectively.
6. Competitive Intensity
Competitive intensity refers to the number and strength of competitors already serving a segment.
Key Questions
- How many competitors are present?
- How strong are their brands?
- How loyal are their customers?
- How difficult is it to differentiate?
- Are competitors competing mainly on price?
A highly competitive segment may require large marketing investments and lower prices, reducing profitability.
7. Strategic Fit
Strategic fit measures how well a segment matches the company's mission, brand, resources, capabilities, and long-term objectives.
Strategic Fit Includes
- Compatibility with the company's brand.
- Availability of suitable products.
- Relevant technical expertise.
- Distribution capability.
- Financial resources.
- Sales and service capacity.
Example: A premium fashion brand may damage its image by entering a very low-price market segment without a separate brand strategy.
8. Segment Stability
Segment stability refers to whether customer needs and behavior are likely to remain consistent for a reasonable period.
Some segments may be based on temporary trends that disappear quickly.
Signs of Stability
- Consistent demand.
- Long-term customer need.
- Predictable purchasing behavior.
- Limited dependence on short-lived trends.
9. Risk Level
Every segment carries business risk. A company should identify and assess potential threats before entering.
Common Risks
- Economic uncertainty.
- Regulatory restrictions.
- Rapid technological change.
- Unstable customer demand.
- New competitor entry.
- Supply chain problems.
- Changing customer preferences.
10. Long-Term Customer Value
Long-term customer value considers the total revenue and profit a customer may generate throughout the relationship with the company.
A segment with moderate initial sales may still be attractive if customers purchase repeatedly, remain loyal, and recommend the brand to others.
Long-Term Value Indicators
- Repeat purchase frequency.
- Customer retention rate.
- Cross-selling potential.
- Upselling potential.
- Referral behavior.
- Customer lifetime value.
Characteristics of an Attractive Market Segment
| Criterion | Meaning |
|---|---|
| Measurable | The size and purchasing power can be estimated. |
| Substantial | The segment is large or profitable enough. |
| Accessible | The company can reach and serve the segment. |
| Differentiable | The segment responds differently from other groups. |
| Actionable | The company can create effective strategies for it. |
| Profitable | Expected returns exceed the cost of serving it. |
| Stable | The segment remains commercially relevant over time. |
Segment Evaluation Matrix
A segment evaluation matrix helps businesses compare different market segments using weighted criteria.
| Evaluation Criterion | Weight | Segment A Score | Segment B Score | Segment C Score |
|---|---|---|---|---|
| Market Size | 20% | 4 | 5 | 3 |
| Growth Potential | 20% | 5 | 3 | 4 |
| Profitability | 25% | 4 | 3 | 5 |
| Accessibility | 15% | 5 | 4 | 3 |
| Strategic Fit | 20% | 5 | 3 | 4 |
Each segment may be scored from 1 to 5, where 1 represents very weak performance and 5 represents excellent performance.
How to Calculate a Weighted Score
The weighted score is calculated by multiplying each criterion's weight by the segment's score.
Weighted Score = Criterion Weight × Segment Score
The scores are then added to determine the overall attractiveness of each segment.
This method improves objectivity by ensuring that important criteria receive greater influence in the final decision.
Example: Evaluating Segments for an Online Learning Platform
An online learning company identifies three possible customer segments:
- University students.
- Working professionals.
- Corporate clients.
| Criterion | University Students | Working Professionals | Corporate Clients |
|---|---|---|---|
| Market Size | High | High | Medium |
| Growth Potential | Medium | High | High |
| Profitability | Low to Medium | High | Very High |
| Accessibility | High | High | Medium |
| Sales Cycle | Short | Short | Long |
| Strategic Fit | High | Very High | Medium |
The company may choose working professionals as its primary target because the segment offers strong growth, high accessibility, good profitability, and excellent strategic fit.
Quantitative Evaluation Methods
Businesses may use numerical methods to evaluate market segments.
Common Measures
- Market size.
- Market growth rate.
- Average customer spending.
- Customer acquisition cost.
- Customer lifetime value.
- Expected profit margin.
- Conversion rate.
- Retention rate.
Qualitative Evaluation Methods
Not every evaluation factor can be measured precisely. Managers also use qualitative judgment.
Qualitative Factors
- Brand compatibility.
- Customer trust.
- Reputation risk.
- Competitive reaction.
- Future strategic importance.
- Organizational readiness.
The strongest evaluation combines quantitative data with informed managerial judgment.
Using SWOT Analysis for Segment Evaluation
SWOT analysis helps businesses evaluate internal and external factors related to a segment.
| Internal Factors | External Factors |
|---|---|
| Strengths | Opportunities |
| Weaknesses | Threats |
Example Questions
- What strengths help us serve this segment?
- What weaknesses may limit our performance?
- What market opportunities are available?
- What threats could reduce profitability?
Common Evaluation Mistakes
- Focusing only on segment size.
- Ignoring customer acquisition costs.
- Underestimating competition.
- Using outdated market data.
- Overestimating company capabilities.
- Ignoring regulatory or economic risks.
- Selecting a segment without measurable customer characteristics.
- Failing to compare alternative segments.
Best Practices
- Use current and reliable data.
- Evaluate both financial and strategic factors.
- Use weighted scoring models.
- Compare multiple segments objectively.
- Estimate costs before estimating profit.
- Include long-term customer value.
- Review segment attractiveness regularly.
- Test assumptions through small-scale market entry.
Practical Activity
Assume you are evaluating three customer segments for a new fitness application:
- University students.
- Working professionals.
- Older adults.
Rate each segment from 1 to 5 using the following table:
| Criterion | University Students | Working Professionals | Older Adults |
|---|---|---|---|
| Market Size | |||
| Growth Potential | |||
| Profitability | |||
| Accessibility | |||
| Strategic Fit | |||
| Competitive Intensity |
After completing the table, select the most attractive segment and justify your decision.
Real-World Example: Tesla
Tesla initially focused on affluent, environmentally conscious, and technology-oriented consumers. This segment was relatively small but attractive because customers had high purchasing power, strong interest in innovation, and willingness to pay premium prices.
As production capacity increased and battery technology improved, Tesla expanded toward broader market segments with more affordable models. This demonstrates how segment attractiveness can change over time as company capabilities and market conditions evolve.
Key Takeaways
- Not every identified market segment should be targeted.
- Segments should be evaluated based on size, growth, profitability, accessibility, competition, and strategic fit.
- Customer lifetime value is often more important than immediate sales.
- A weighted evaluation matrix improves objectivity.
- Quantitative data should be combined with qualitative managerial judgment.
- Segment attractiveness should be reviewed regularly as markets change.
Lesson Summary
Evaluating market segments is a critical step in the STP process. Businesses must compare segments carefully before investing resources. The strongest target segments are measurable, accessible, profitable, strategically suitable, and capable of delivering sustainable long-term value. A structured evaluation process reduces risk and improves the quality of target market decisions.
