Intangibility means that buyers of services cannot feel, see, hear, or taste the services before it is bought. In the context of marketing and business, services offer various intangible aspects that can differentiate a product or service from others. These aspects may include guarantees of satisfaction, reputations for high quality, value-added services like free delivery, or financial offerings such as loans to facilitate purchases. Moreover, much of product differentiation occurs in the minds of consumers, influenced by past habits and advertising, creating preferences for certain brands that may not be based on tangible differences.
