There are several differences between marketing goods and marketing services. One is that we are marketing something intangible when we market a service, something the consumer cannot put his or her hands on, for example, banking services, life insurance, or education. That can make for a difficult "sell." Another significant difference is that services are often consumed immediately, so marketing them eliminates the possibility of "displaying" them. How do you market a haircut? A third difference is that services are often a function of geography because consumers do not generally travel very far for them. This limits service markets significantly and consequently affects one's marketing strategies. Finally, marketing depends a great deal on getting feedback, and it can be difficult or impossible to rate the satisfaction of the consumer in getting the service.
