Key Brand Equity Models

Why This Matters

Brand equity models aren't just academic frameworks—they're the diagnostic tools you'll use to understand why consumers pay premium prices, stay loyal through crises, and become brand advocates. Every major marketing decision, from repositioning a struggling brand to valuing one for acquisition, relies on these models. You're being tested on your ability to identify which model applies to specific business scenarios, compare their underlying assumptions about how brands create value, and explain why different measurement approaches yield different strategic insights.

These models fall into distinct camps: some prioritize consumer psychology (what's happening in people's heads), others focus on financial outcomes (what shows up on balance sheets), and still others track brand health metrics over time. Don't just memorize the components of each model—know what question each model is designed to answer and when you'd choose one over another. That comparative thinking is what separates strong exam responses from surface-level recall.

Consumer Psychology Models

These frameworks start from the inside out—they measure what's happening in consumers' minds and assume that strong mental associations drive market performance. The core principle: brand equity lives in consumer perception, not in financial statements.

Aaker's Brand Equity Model

• Four dimensions define brand strength—brand loyalty, brand awareness, perceived quality, and brand associations work together to create competitive advantage
• Brand loyalty drives long-term profitability because retaining customers costs less than acquiring new ones—this is the dimension Aaker considers most valuable
• Proprietary assets like patents and trademarks represent a fifth, often overlooked dimension that protects equity from competitive erosion

Keller's Customer-Based Brand Equity (CBBE) Model

• Brand equity equals differential effect—defined as how brand knowledge changes consumer response to marketing compared to an unbranded product
• Pyramid structure moves through four sequential stages: identity (who are you?), meaning (what are you?), response (what do I think/feel?), and resonance (what relationship do we have?)
• Resonance at the apex represents the ultimate goal—active engagement, attitudinal attachment, sense of community, and behavioral loyalty

Brand Resonance Model

• Deep psychological connection is the endpoint—Keller's resonance model (an extension of CBBE) treats intense loyalty and advocacy as the measurable outcome of successful brand building
• Four resonance dimensions include behavioral loyalty, attitudinal attachment, sense of community, and active engagement—all must be present for true resonance
• Brand communities matter strategically because they transform customers into advocates who recruit others and defend the brand during crises

Brand Health Measurement Models

These models are designed for ongoing tracking and competitive benchmarking. The core principle: brand equity fluctuates over time, and marketers need dashboards to monitor health and spot problems early.

BrandAsset Valuator (BAV)

• Four pillars create a diagnostic grid—differentiation, relevance, esteem, and knowledge combine to reveal where a brand sits in its lifecycle
• Power Grid placement matters: brands high in differentiation but low in knowledge are emerging; those high in knowledge but low in differentiation are eroding—this lifecycle insight is unique to BAV
• Developed by Young & Rubicam using data from hundreds of thousands of consumers across dozens of countries, making it one of the largest brand research databases available

Millward Brown's BrandDynamics

• Pyramid of brand relationships tracks consumers from presence → relevance → performance → advantage → bonding, with each level representing deeper commitment
• Bonding at the top identifies consumers who feel the brand has no acceptable substitute—these are your most valuable, least price-sensitive customers
• Conversion ratios between levels reveal where marketing is failing; a brand with high awareness but low bonding has a relationship problem, not an awareness problem

Brand Equity Ten

• Ten metrics provide granular diagnosis—Millward Brown's expanded framework measures awareness, relevance, performance, advantage, bonding, and five additional consumer perception indicators
• Practical tracking tool designed for longitudinal measurement, allowing marketers to monitor equity changes quarter over quarter
• Holistic brand health view helps identify whether declines stem from awareness gaps, relevance drift, or weakening emotional connections

Financial Valuation Models

These frameworks translate consumer perceptions into dollar figures. The core principle: brand equity must ultimately show up in financial performance to matter to executives and investors.

Interbrand's Brand Valuation Model

• Three-factor calculation combines financial performance (economic profit attributable to the brand), role of brand (how much brand drives purchase decisions in the category), and brand strength (competitive resilience)
• Brand strength assessment evaluates ten factors including clarity, commitment, responsiveness, and relevance—this qualitative component adjusts the discount rate applied to future earnings
• Annual Global Brand Rankings published by Interbrand influence investor perceptions and executive compensation, making this the most publicly visible valuation methodology

Self-Check Questions

1. Which two models use a pyramid structure, and how do their pyramids differ in what they measure?

2. A brand has high awareness and strong perceived quality but declining market share. Using Aaker's four dimensions, which dimension is most likely the problem, and why?

3. Compare the BAV and Interbrand models: one is primarily diagnostic, the other primarily evaluative. Which is which, and what business decision would each inform?

4. If an FRQ asks you to explain how a brand achieves "resonance," which model provides the framework, and what four components must be present?

5. A private equity firm wants to acquire a consumer brand and needs to justify the purchase price to investors. Which model would they most likely use, and what three factors would drive the valuation?
