Online reputation is a strategic element of firms' competitiveness. Companies need to manage their reputations and the image that they communicate through the Internet. This paper proposes a model to determine the main aspects that define a competitive online reputation: coherence, veracity, and intensity. The traditional methods that have been used to determine service quality must be adapted to new digital developments and their effects on customers' behavior. Therefore, a gap analysis is performed to define the key aspects that must be managed in order to create and maintain a powerful reputation and image in the companies' communication. Since this subject is too complex to be implemented in distinct sectors and ambits, different lines of research are proposed to expand this new critical line of study.As online reputation is becoming a critical factor for the level of income of companies, it is necessary to develop a communication strategy to achieve the economic sustainability of tourism or e-commerce firms [36,37] and tourist destinations [38,39]. At present, it is necessary to consider the model for measuring the quality of customer service due to technological and communications development. While the method for measuring quality has been based on internal surveys of companies carried out among their customers [9], the rise of opinion portals on the Internet has led to a new way of measuring the quality of service in an open way and shared with other users. In addition, the impact on demand is so high that it is critical for managers to guide their decisions to improve their online reputation [3,5,7].The objective of this study is to propose a model to determine the gaps that managers must take into account to achieve an effective reputation on the web. This methodology is designed to improve the analysis and decisions made by practitioners and serve as a source of information for researchers. The methodology and evaluations proposed can be applied to sectors with high Internet communication activity, such as hospitality and e-commerce. In order to achieve this objective, the next section presents a literature review with the aim of formulating a model for gap analysis of the online reputation in the methodology section. Finally, the main conclusions and future research focused on developing this line of research are presented.
