Brand Equity Research: What to Measure and How to Use It
Brand equity research examines how a brand changes what consumers remember, believe and choose. It helps a business identify whether its strength lies in awareness, useful associations, perceived quality or preference, and where barriers remain. The purpose is to guide a decision, rather than produce an unexplained overall score.
For a business in Vietnam, the practical question might be why a familiar brand is rarely considered, or why satisfied users still choose a competitor. This guide focuses on consumer-based brand equity: what to measure, how to design the study and how to interpret the evidence.
Brand equity and financial brand valuation answer different questions
Consumer-based brand equity concerns the effect of brand knowledge on consumer responses. Kevin Lane Keller’s foundational research explains this perspective. Consumer studies can investigate such differences, but a questionnaire does not, by itself, establish a monetary brand value.
Financial valuation requires its own data, assumptions and method. Equally, strong sales alone do not prove strong consumer preference: distribution, price and promotions also affect purchases. Agree at the briefing stage whether the business needs consumer understanding, a financial valuation or separate workstreams.
Which dimensions should a study measure?
Select measures around the decision and category. The following is a practical planning framework, not a proprietary INTAGE index or a universal scoring formula.
| Dimension | Possible evidence | Design safeguard |
|---|---|---|
| Awareness | Unaided recall and aided recognition | Ask unaided questions before showing brand names |
| Associations and difference | Attributes linked to each brand | Use relevant attributes without leading respondents |
| Perceived quality and value | Performance, trust and value for money | Separate users from people who only know the name |
| Consideration and preference | Brands considered or preferred for the next occasion | Specify the occasion and choice conditions |
| Relationship and behaviour | Repurchase intention, recent use and repeat purchases | Separate stated intentions from recorded transactions |
For questionnaire ordering and definitions, see our guide to measuring brand awareness and recall. A single metric, including NPS, should not stand in for the entire brand equity assessment.
Design the study around a business decision
- Define the decision. Improving communication, testing positioning and investigating purchase barriers require different outputs.
- Define the population. Category buyers, current users, lapsed users and non-buyers play different roles. Specify geography, age and eligibility instead of treating available respondents as the market.
- Explore consumer language. Interviews or group discussions can identify relevant attributes and understandable wording before a survey measures them.
- Compare on consistent terms. Use equivalent questions, scales and respondent eligibility for each brand. Pilot the questionnaire and check understanding before fieldwork.
- Check and analyse the data. Review response quality, achieved bases for each comparison, weighting where applicable and uncertainty around differences.
- Translate evidence into action. State what is supported, which explanations remain hypotheses and what should be tested next.
Qualtrics’ brand study guidance illustrates sections covering awareness, usage and brand imagery, and the importance of consistent questions across brands. In Vietnam, pilot the language with the intended audience and interview mode; a translation that sounds fluent may still communicate a different attribute.
Use the findings to distinguish different problems
Illustrative example: a personal-care brand is widely known but rarely considered. If potential buyers cannot explain its benefit, the business may need to test communication and relevance. If people want to buy but cannot find it, availability and channel execution need investigation. Both situations can produce low purchasing, while calling for different actions. This example is hypothetical, not a reported INTAGE client result.
Compare users with non-users, priority audiences with the category and the relevant competitors. A brand positioning map can summarize associations. Interpret its distances according to the mapping method; empty space is not automatically an attractive market opportunity.
Where coverage and sample fit the category and question, iPanel INTAGE shopper data can add recorded-purchase context. Transactions describe observed behaviour, while surveys and interviews investigate perceptions and possible reasons. Neither source automatically replaces the other, and linking evidence requires compatible definitions and periods.
Common mistakes and limits
- Surveying only existing customers and generalizing to all category buyers.
- Comparing waves with different samples, seasons or collection modes without explaining the differences.
- Combining metrics into an index without specifying weights, validation and interpretation.
- Treating an association between perceptions and purchases as proof of causation.
- Promising sales growth from survey results or treating a stated willingness to pay as a guaranteed achievable price.
For tracking, keep core questions, eligibility and metric definitions stable. Assess changes to tools or competitor lists before interpreting a movement as a brand trend. Report subgroup bases and uncertainty rather than ranking small differences as certain wins or losses.
Prepare a brand equity research brief
Share your category, brand and competitors, target buyers, locations, business decision and deadline. If previous studies exist, include their questionnaires, fieldwork dates and metric definitions so comparability can be assessed. INTAGE Vietnam can discuss a suitable design through its market research services, with the sample, scope, analysis and deliverables agreed for the project.
