What is a unique selling proposition (USP)?

A unique selling proposition (USP) is fundamentally defined as the factor that differentiates a product from its competitors. This concept is crucial in marketing because it highlights the distinctive benefits or features that make a product stand out in the marketplace. A well-defined USP communicates why consumers should choose one product over another and addresses their needs or pain points more effectively than competing offerings.

In building a brand's identity and value proposition, the USP can focus on various aspects, such as quality, features, pricing, customer service, or even the brand's mission. By emphasizing these unique aspects, companies can create a strong competitive advantage and foster customer loyalty.

The other options do not encapsulate the essence of a USP. The price of a product, while important, does not inherently differentiate it unless aligned with a broader value proposition. The geographical market refers to where a product is sold, which is more about distribution strategy than differentiation. Lastly, total sales volume measures performance rather than the unique attributes that warrant a customer's choice.
