Definition: Segmentation means to divide the marketplace into parts, or segments, which are definable, accessible, actionable, and profitable and have a growth potential. In other words, a company would find it impossible to target the entire market, because of time, cost and effort restrictions. It needs to have a 'definable' segment - a mass of people who can be identified and targeted with reasonable effort, cost and time.

Once such a mass is identified, it has to be checked that this mass can actually be targeted with the resources at hand, or the segment should be accessible to the company. Beyond this, will the segment respond to marketing actions by the company (ads, prices, schemes, promos) or, is it actionable by the company? After this check, even though the product and the target are clear, is it profitable to sell to them? Is the number and value of the segment going to grow, such that the product also grows in sales and profits?

Description: Segmentation takes on great significance in today's cluttered marketplace, with thousands of products, media proliferation, ad-fatigue and general economic problems around the world markets. Rightly segmenting the market place can make the difference between successes and shut down for a company.

Segmentation allows a seller to closely tailor his product to the needs, desires, uses and paying ability of customers. It allows sellers to concentrate on their resources, money, time and effort on a profitable market, which will grow in numbers, usage and value.
