Brand personality is the way a brand speaks and behaves. It means assigning human personality traits/characteristics to a brand so as to achieve differentiation. These characteristics signify brand behaviour through both individuals representing the brand (i.e. it’s employees) as well as through advertising, packaging, etc.

When brand image or brand identity is expressed in terms of human traits, it is called brand personality. For instance - Allen Solley brand speaks the personality and makes the individual who wears it stand apart from the crowd. Infosys represents uniqueness, value, and intellectualism.

Brand personality is nothing but personification of brand. A brand is expressed either as a personality who embodies these personality traits (For instance - Shahrukh Khan and Airtel, John Abraham and Castrol) or distinct personality traits (For instance - Dove as honest, feminist and optimist; Hewlett Packard brand represents accomplishment, competency and influence).

Brand personality is the result of all the consumer’s experiences with the brand. It is unique and long lasting.

Brand personality must be differentiated from brand image, in sense that, while brand image denote the tangible (physical and functional) benefits and attributes of a brand, brand personality indicates emotional associations of the brand.

If brand image is comprehensive brand according to consumers’ opinion, brand personality is that aspect of comprehensive brand which generates it’s emotional character and associations in consumers’ mind.

Brand personality develops brand equity. It sets the brand attitude. It is a key input into the look and feel of any communication or marketing activity by the brand. It helps in gaining thorough knowledge of customers feelings about the brand. Brand personality differentiates among brands specifically when they are alike in many attributes. For instance - Sony versus Panasonic.

Brand personality is used to make the brand strategy lively, i.e, to implement brand strategy. Brand personality indicates the kind of relationship a customer has with the brand. It is a means by which a customer communicates his own identity.

Brand personality and celebrity should supplement each other. Trustworthy celebrity ensures immediate awareness, acceptability and optimism towards the brand. This will influence consumers’ purchase decision and also create brand loyalty. For instance - Bollywood actress Priyanka Chopra is brand ambassador for J.Hampstead, international line of premium shirts.

Brand personality not only includes the personality features/characteristics, but also the demographic features like age, gender or class and psychographic features. Personality traits are what the brand exists for.
