Market segmentation is the process of dividing a large group of potential customers into smaller groups that share similar needs, habits, or characteristics. It matters because most products cannot satisfy everyone equally well. By identifying clear customer segments, a business can design better products, choose better prices, and create messages that feel relevant to the right people.
Segmentation helps entrepreneurs use limited time and money more wisely.
Key Facts
- Market segmentation = dividing a broad market into smaller customer groups with shared traits.
- Common segmentation types include demographic, geographic, psychographic, and behavioral segmentation.
- A strong segment should be measurable, reachable, substantial, and likely to respond to a tailored offer.
- Market share = company sales ÷ total market sales.
- Segment size percentage = segment customers ÷ total customers × 100%.
- Target market = the segment or segments a business chooses to serve.
Vocabulary
- Market segmentation
- Market segmentation is the process of dividing a broad market into smaller groups of customers with similar needs or traits.
- Target market
- A target market is the specific customer segment a business chooses to focus on and serve.
- Demographic segmentation
- Demographic segmentation groups customers by traits such as age, income, education, family size, or occupation.
- Psychographic segmentation
- Psychographic segmentation groups customers by lifestyle, values, interests, attitudes, or personality.
- Behavioral segmentation
- Behavioral segmentation groups customers by actions such as buying frequency, brand loyalty, product usage, or benefits sought.
Common Mistakes to Avoid
- Trying to sell to everyone, which is wrong because a broad message usually feels vague and wastes marketing resources.
- Segmenting only by age, which is wrong because customers of the same age can have very different needs, incomes, lifestyles, and buying behaviors.
- Choosing a segment that is too small to support the business, which is wrong because even a perfect fit may not create enough sales or profit.
- Ignoring whether a segment can be reached, which is wrong because a business needs practical channels such as social media, local stores, email, or events to communicate with that group.
