What are you doing to ensure that your new customer will come back in a week? If your answer is nothing or if you have not thought about it then you must look into four walls marketing. Four walls marketing is based on the idea that it is easier to convert a customer into a regular customer than it is to bring in new customers. Why spend money on ads that reach hundreds when you can use what you already have to create long-term relationships with your current customers.
