How do you classify customers according to their character?

Thank you. I also agree with opinion of experts. Thanks.

Thank you for the invitation.

I Agree with Mr.  Sooraj

Customers could be classified  using taste and preference, frequency of buying, quantity purchased, product purchased and loyalty.      

their willing to buy is obvious by the type of questions they ask, if they want it luxury or just to fulfill a need, if they looking for a good deal or good post-sell services, and so on. 

A buyer can be identified by the type of questions they ask, and what type of product they looking for. 

Customer classification  [segmentation] is the practice of dividing a customer base into groups of individuals that are similar in specific ways relevant to marketing, such as age, gender, interests and spending habits. Customer segmentation, also called consumer segmentation or client segmentation.

There are five types of customers are there .

Loyal Customers : They represent no more than 20 percent of our customer base, but make up more than 50 percent of our sales.

Discount Customers : They shop our stores frequently, but make their decisions based on the size of our markdowns.

Impulse Customers : They do not have to buy a particular item at the top of their “To Do” list, but come into the store on a whim. They will purchase what seems good at the time.

Need-Based Customers : They have a specific intention to buy a particular type of item.

Wandering Customers : They have no specific need or desire in mind when they come into the store. Rather, they want a sense of experience and/or community.
