Considering Aaker’s model, strong interrelationships occur among the dimensions of brand equity. The last four brand equity dimensions can enhance brand loyalty, providing reason to buy and affecting use satisfaction.
Even when they are not pivotal to brand choice, they can reassure, reducing the incentive to try others.
Therefore, brand loyalty is both one of the dimensions of brand equity and is affected by brand equity and the other assets that generate equity.
In the same way, perceived quality could be influenced by awareness (a visible name is likely to be well made), by associations (a visible spokesperson would only endorse a quality product) and by loyalty (a loyal customer would not like a poor product).
In some circumstances it might be useful to explicitly include brand equity dimensions as outputs of brand equity as well as inputs.
