Target Market/Customers

Finding and evaluating target customers 

Knowledge is everything when it comes to identifying which groups of customers you should be targeting. Market research will help you understand more about the needs, tastes and spending habits of different groups of potential customers. This should tell you about the customer segments most likely to buy into your offer and the kind of marketing and sales activities they will respond to.
Understanding what your rivals are up to is critical. Questions to ask yourself:
How are they working with your target groups? would you do better or worse? Where are the gaps in their offer and in their marketing? Are group of customers being ignored by rivals? Could you target these profitably?

Target Market

Not all customers are the same. A target market represents a specific type of buyer that a company has identified as potentially interested in the company's product or service. A target market can represent an identified niche. For example, a small manufacturer might tailor its design and production outputs to the home textiles market, which represents a relatively large market segment. The manufacturer can also tailor its productions to environmentally conscious consumers, similar to Europe's Ecolabel textile products. In such a case, the manufacturer can then market products to both general retailers in the household textile market and retailers in the niche environmental products market.
