Market targeting involves developing measures to evaluate market segments and selecting one or more segments to enter. Key factors in evaluating segments include current size, growth potential, and attractiveness, as well as company objectives and resources. There are four main marketing strategies: undifferentiated targets the whole market with one offer; differentiated designs separate offers for different segments; concentrated focuses on one segment; and micro targets specific individuals and locations. Examples of each include mineral water, airlines, fossils, and local grocery stores respectively.
