The document defines a unique selling point (USP) as something that makes a product attractive to potential customers by suggesting a specific benefit that competitors do not offer. Creating a strong USP is important because without one, a product will not stand out and consumers will only compare options based on price. A good USP should uniquely position a product and be compelling enough to attract new customers. The document provides examples of well-known USPs and asks the reader to identify products based on their USPs. It emphasizes that an effective USP singles out a product from competitors in a way that appeals to consumers.
