Consumer is now a day treated as “KING” and it is very difficult to understand consumer behavior as consumer behavior is complex. Consumers are rational they think before buying. Therefore the marketer must understand the consumer behavior before starting the marketing strategy. He must study the likes and dislikes of the consumer. All consumers are different in their cultural background, income, life style, personality, beliefs and attitudes etc. But one thing is common as all of them are “consumer”. So the marketing manager must know the answer of following questions. Like:

 What customers like to buy?

When they buy?

How they buy?

Why they buy?

From where they buy?
