Brand plays an important role in the highly competitive environment we face today. It is more than just a name or a logo. It has many facets, including marketing communications. For brands, understanding the key elements of their strategy is essential for effective management and strategic decision-making in this dynamic and ever-changing environment. The aim of this paper is to develop and subsequently validate an instrument to measure three key aspects of brand: brand awareness (A), brand image (I), and customer loyalty (L). The measurement tool (model) is based on an original questionnaire designed to measure the three aspects mentioned above. To increase validity, the primary model was modified based on factor confirmatory analysis, which led to the development of an alternative model that improved the fit of the data by removing items with low factor loadings. The aforementioned confirmatory factor analysis (CFA), reliability and validity measures, and model fit indices were used to validate the questionnaire. The insights provided by this model can provide a wealth of data for brands to develop and foster the innovation that keeps them competitive. The results of the study suggest that the questionnaire developed to measure key brand aspects—namely brand awareness, brand image and brand loyalty—is effective and reliable. The questionnaire demonstrated strong psychometric properties, including high internal consistency and good agreement, and is thus able to accurately capture and assess these brand aspects.
