Brand Equity Scale

The Brand Equity Scale (BES) measures customer-based brand equity through perceived quality, brand loyalty, brand associations, and brand awareness. Developed by Yoo, Donthu, and Lee (2000), building on Aaker's foundational brand equity framework (1991), the BES operationalizes brand equity as the differential effect of brand knowledge on consumer response to marketing activities. The scale enables organizations to quantify the value customers attach to their brand and diagnose which equity dimensions require strategic investment.
