Brand equity refers to the value added to a product or service by its brand name. There are four main dimensions of brand equity: brand awareness and associations in consumers' minds, influence on purchase behavior, impact on market position and financial performance, and the monetary value of the brand as an asset. Brand equity is created through strong, favorable, and unique brand associations related to the brand's awareness, perceived quality, loyalty, and other attributes. Measuring these dimensions can provide an assessment of a brand's relative strength and equity.
