What are the patterns of segmentation?

PATTERNS OF SEGMENTATION
Undifferentiated Marketing: 

Under this strategy, the producer or marketer does not differentiate between different type of customers. One marketing mix is used for the whole market. Eg. Pepsi.

Differentiated Marketing: 

Several market segments are identified and different marketing mix is developed for each of the segments. Eg; consumer products.

Concentrated Marketing: 

It is concerned with the concentration of all marketing efforts on one selected segment within the total market. Eg; Kid’s wear.

Customized or Personalized Marketing: 

In this case, firms view each customer as a separate segment and customized marketing programmes to that individual's specific requirements. Eg; civil engineers designing flats, villas, bridges, etc.
