Brand stands for one, or two things. Rarely more than two.
It means your customers remember you for a certain kind of product or service. It also means every time they buy from you, they expect a certain experience. This expectation could be a result of a prior purchase from you or because someone told them that you are good.
In any of the cases, they recalled your name because of a certain positive associated memory. That is branding!
Do you have a brand? Is it memorable? What do customer think when they think about the product or service that you sell?
