As a marketer, What are the qualities of useful market segments?

Some important qualities are:

• -Its easily accessible 
• -Its easily measurable
• -it consists of homogeneous individuals
• -It can be easily differentiated from other segments

• Segments must have enough profit potential to justify developing and maintaining 
• Consumer must have heterogeneous needs for the product
• Segmented consumer needs must be homogeneous 
• Company must be able to reach a segment with its planned efforts. Must be able to measure characteristics & needs of consumers to establish groups.  

It depends on the co strategy. For some the niche market segment would be more profitable. Some cos ouldgo for product penaetration of a larger chunk of market.

The main qualities of a useful market segment is that it must be measurable, actionable, accessible, substantial and differential.

The main points which I look necessary are :

a) Product Availability

b) Product Promotion

c) Product Knowledge

d) Product Price

e) Services

f) Extra benefits in product service rather to focus on price

• It must be large enough to earn profit.
• It is possible to measure.
• It must be stable enough that it does not vanish after some time.
• It is possible to reach potential customers via the organization's promotion and distribution channel.
• It is internally homogeneous (potential customers in the same segment prefer the same product qualities).
• It is externally heterogeneous(potential customers from different segments have different quality preferences).
• It responds consistently to a given market stimulus.
• It can be reached by market intervention in a cost-effective manner.
• It is useful in deciding on the marketing mix.
• It identifies the target customer(s) (surrogate(s))
