Brand equity refers to the sum of consumer attitudes, perceptions, and behaviors associated with a brand, which contribute to its overall value. It is often expressed as a financial valuation based on research and past marketing investments. According to Aaker, this equity rests on five key factors: customer loyalty, brand awareness, perceived quality, brand associations, and other brand-related assets. This concept, which emerged in the 1980s, is also known as “brand equity” and continues to evolve with new research incorporating additional dimensions.
