# Brand Equity

## Overview

Brand equity is the differential effect that brand knowledge has on consumer response. Aaker (1991) identifies five dimensions: awareness, associations, perceived quality, loyalty, and proprietary assets. Keller (1993) structures Customer-Based Brand Equity (CBBE) as a pyramid: Salience, Meaning, Response, and Resonance.

## When to Use

- Auditing brand health and diagnosing weak equity components
- Designing brand-building or repositioning strategies
- Justifying brand investment to stakeholders with a structured framework
- Comparing brand equity positions across competitors

## When NOT to Use

- Valuing a brand financially for M&A (use financial brand valuation methods)
- Short-term promotional effectiveness (use marketing mix models)
- When brand is not a relevant purchase factor (pure commodity markets)

## Assumptions

```
IRON LAW: Brand equity is measured from the CUSTOMER perspective.
Internal brand investment (spend, campaigns) does NOT equal brand
equity. Only customer perceptions and behaviors count.
```

Key assumptions:
1. Brand knowledge (awareness + associations) is stored in consumer memory
2. Brand equity manifests as differential consumer response
3. Equity dimensions are separable and independently measurable
4. Brand equity accumulates over time and is path-dependent

## Methodology

### Step 1 — Map the Aaker dimensions

| Dimension | Key Metrics | Data Sources |
|-----------|------------|--------------|
| **Awareness** | Top-of-mind, aided/unaided recall | Surveys, search data |
| **Associations** | Brand image, personality, positioning | Perceptual maps, qualitative |
| **Perceived Quality** | Quality leadership, consistency | Customer ratings, reviews |
| **Loyalty** | Repeat purchase, price premium willingness | Transaction data, CLV |
| **Proprietary Assets** | Patents, trademarks, channel relationships | Internal audit |

### Step 2 — Build the Keller CBBE pyramid

| Level | Block | Question |
|-------|-------|----------|
| 1. Identity | **Salience** | Who are you? (depth and breadth of awareness) |
| 2. Meaning | **Performance** + **Imagery** | What are you? (functional + abstract associations) |
| 3. Response | **Judgments** + **Feelings** | What about you? (opinions + emotions) |
| 4. Relationships | **Resonance** | What about you and me? (loyalty, community, engagement) |

### Step 3 — Identify equity gaps

Compare current state to desired positioning. Identify which pyramid level or Aaker dimension is the bottleneck.

### Step 4 — Design brand-building actions

Target the weakest pyramid level with specific marketing programs. Build from bottom up — salience before meaning, meaning before response.

## Gotchas

- Awareness without strong associations is hollow equity — recognition alone is insufficient
- High perceived quality can coexist with low loyalty if switching costs are low
- Brand equity is category-specific; a strong brand in one category may have zero equity in another
- Negative brand equity exists — some brands actively repel segments
- Do not conflate brand equity with brand valuation; equity is perceptual, valuation is financial
- Proprietary assets (Aaker's 5th dimension) are often omitted in research but critical in practice
