I am sure you cannot profile them physically because you cannot see their reaction to your product and services, for the best thing is through their comments and testimony or even the word-of-mouth, because even if they don't like you personally but the product and services you offered would speak for themselves..you can also look for the most salable items drawing from that you can make conclusions that they want this product or you may want to improve on it ...hope I gave you an idea have a nice day
