Final answer:
The term describing factors that make a product unique and encourage customers to purchase it is the 'unique selling point' (USP), which can involve intangible aspects and is often reinforced by advertising.
Step-by-step explanation:
Factors that make a company's product unique and motivate customers to buy are known as a unique selling point (USP). A USP can be a distinguishing feature that sets a product apart from its competitors. Differentiation can be achieved through various dimensions such as physical aspects of the product, the location from which the product is sold, intangible aspects of the product, and perceptions of the product. Intangible aspects include promises such as a guarantee of satisfaction or money back, a reputation for high quality, services like free delivery, or offering a loan to purchase the product. Product differentiation often occurs in the minds of buyers and can be strongly influenced by advertising, which shapes the preferences for certain brands even when the physical differences are not discernible, such as the taste differences between common varieties of ketchup, mayonnaise, beer, or cigarettes when blindfolded.
