What is niche marketing? One way to define it is as a specialized area of demand. Like in ecology, every plant or animal has very specific needs for their niche, like a home, a job, a function, food, and so forth.
Niche marketing is the process of identifying valuable market segments and designing custom-made products or services for them. When the conditions are right the animal survives and stays around. Similarly when the market meets the needs of the person in a particular niche, that person stays around or returns.
