Over the last few years, the concept of online loyalty has been examined extensively in the literature, and it remains a topic of constant inquiry for both academics and marketing managers. The tremendous development of the Internet for both marketing and e-commerce settings, in conjunction with the growing desire of consumers to purchase online, has promoted two main outcomes: (a) increasing numbers of Business-to-Customer companies running businesses online and (b) the development of a variety of different e-loyalty research models. However, current research lacks a systematic review of the literature that provides a general conceptual framework on eloyalty, which would help managers to understand their customers better, to take advantage of industry-related factors, and to improve their service quality. The present study is an attempt to critically synthesize results from multiple empirical studies on e-loyalty. Our findings illustrate that 62 instruments for measuring eloyalty are currently in use, influenced predominantly by Zeithaml et al. (J Marketing. 1996;60(2):31-46) and Oliver (1997; Satisfaction: a behavioral perspective on the consumer. New York: McGraw Hill). Additionally, we propose a new general conceptual framework, which leads to antecedents dividing e-loyalty on the basis of the action of purchase into pre-purchase, during-purchase and after-purchase factors. To conclude, a number of managerial implementations are suggested in order to help marketing managers increase their customers' e-loyalty by making crucial changes in each purchase stage.Keywords: e-loyalty, e-satisfaction, e-trust, customer behaviour, e-commerce, critical review, framework The penetration of the Internet in marketing and e-commerce settings has influenced, to a great extent, the entire business world.

From the business perspective, market globalization, along with the decreasing effectiveness of offline marketing, has motivated organizations to shift their plans to include Internet marketing [120]. Hence, consumers have increasingly favoured online shopping [166], gradually leading more Business-to-Customer (B2C) companies to establish an Internet presence in an effort to attract new and maintain existing customers for long-term profitability [203]. Building and maintaining brand loyalty has been a central theme of marketing theory and practice in traditional consumer marketing [71]. For this reason, businesses should be more interested in keeping long-lasting relationships with their customers than in accumulating occasional exchanges [17]. Presently, the notion of brand loyalty has been expanded to include online loyalty (also known as e-loyalty or website loyalty). The online shopping world has completely changed the relationship between customers and retailers. The minimal cost to a customer to switch brands (compared to the high costs for companies to acquire new e-customers) just...
