More and more consumers are moving away from physical stores and opting for online shopping. The online stores we choose depend on a number of different factors, such as products available, price, discounts, and, the most important of all: user experience. User experience is shaped by the online store's user interface, its support system, its available guidance, and its searching and recommendation systems.
In this chapter, we will explore the following topics:
