Keller, KL. (2001): Building Customer - Based Brand Equity: A Blueprint for Creating Strong Brands, Working paper Marketing Science Institute In this article, Keller introduces the Customer-Based Brand Equity model, CBBE, which can be used as a tool to assist a company in building a strong brand. According to the model, building a strong brand involves following four steps in this specific order: 1. Establishing the proper brand identity 2. Creating the appropriate brand meaning 3. Eliciting positive, accessible brand responses 4. Forging brand relationships with the right customers To follow and establish the four steps above is a complicated process. To make it easier, the CBBE model provides six “brand-building blocks” in order to succeed with the four steps above. 1. Brand Salience 2. Brand performance 3. Brand imagery 4. Brand judgments 5. Brand feelings 6. Brand resonance (the most valuable brand-building block, can only occur once all the other blocks have already been established). These six building blocks can be put together into a brand pyramid. The higher up in the pyramid the brand has climbed, the higher the brand equity. In addition, these levels have been split into blocks, which represent the six brand building blocks. The first block is about building a strong brand identity which is achieved by creating brand saliency which can be described as how strong the presence of your brand is and how easily it comes to mind. Brand awareness can be split into two key dimensions: depth and breadth. Depth is how easily recognized the brand is while breadth is the range of different contexts where the brand comes to mind in the customers daily lives. Secondly, an established brand image is an important part when creating a brand's meaning. The brand image consists of two parts; performance and imagery-related considerations. Brand performance is about the product itself and how it influences the consumers. It can be divided into different aspects, for example primary characteristics, secondary features and product reliability. Brand imagery on the other hand, is about how the brand manages to meet the social and psychological needs of the customers, and the people’s thoughts on the brand itself. This includes user profiles such as; purchase and usage situations, personality and values, history, heritage and experience. The third block, brand responses, concerns how the customers respond to the brand and can be divided into brand judgements and brand feelings. Brand judgment is about the personal opinions of the customers and can be summarized into brand quality, brand credibility, brand consideration and brand superiority. Brand feelings are about how the brand makes the customers feel, either about themselves or in relationship to others. Brand relationships is the last block and is also known as brand resonance. It puts focus on how the customer identifies with the brand. It is about the psychological bond between customer and brand, as well as the activity that comes along with the loyalty, such as repeated purchases. Brand resonance can itself be divided into four different categories: Behavioral loyalty, attitude attachment, sense of community, and active engagement.
