The concept of brand loyalty has been extensively discussed in traditional marketing literature with the main emphasis on two different dimensions of the concept: behavioral and attitudinal loyalty. Oliver (1997) has presented a conceptual framework of brand loyalty that includes the full spectrum of brand loyalty based on a hierarchy of effects model with cognitive, affective, conative (behavioral intent), and action (repeat purchase behavior) dimensions. A definition integrating this multidimensional construct has been given (Oliver, 1999) as: "a deeply held commitment to rebuy or repatronize a preferred product/service consistently in the future, thereby causing repetitive same-brand or same brand-set purchasing, despite situational influences and marketing efforts having the potential to cause switching behavior." The concept of e-loyalty extends the traditional brand loyalty concept to online consumer behavior. Although the underlying theoretical foundations of traditional brand loyalty and the newly defined phenomena of e-loyalty are generally similar, there are unique aspects of it in the area of Internet based marketing and buyer behavior.
