Several studies have empirically explored the association between practices in sustainable tourism and their impact on tourism marketing. However, bibliometric studies that organize the production in this field are still scarce. The objective of this study is thus to provide a bibliometric analysis of research on sustainable practices in tourism related to marketing, identifying the state of the art, trends and other indicators, by monitoring the articles published on the Web of Science (WoS) platform. A sample of 694 materials was obtained. The data were processed and the results graphically illustrated using the VOSviewer software. The study analyzed the simultaneous occurrence of publications by year, keyword trends, cocitations, bibliographic coupling and analysis of coauthorship, countries and institutions, and indicates that the literature on tourism sustainability issues in the field of tourism marketing is growing at a quick pace; merely five papers accounted for more than 2193 citations, but there are several prolific authors. Of the 694 sources included in the review, the most important ones published 40.34% of the papers; Spain is the leading country in this topic. This research provides insight about the state of the art and identifies gaps and research opportunities in sustainability and tourism marketing.

Corporate social responsibility (CSR) and business ethics are perceived as distinct constructs by the consumer, although research from this perspective is scarce. Thus, the objective of this study is to investigate the impact of CSR and business ethics on brand fidelity. A theoretical review of CSR, business ethics, brand attitude, brand love, and brand fidelity was undertaken. From these constructs, a theoretical model was proposed, conducting an empirical study with a sample of 559 North American respondents. Through the statistical treatment of data with PLS-SEM, it was demonstrated that business ethics and CSR exert an indirect positive effect on brand fidelity, with relationships mediated by brand love. In turn, brand attitude exerts an indirect effect on brand fidelity, through the mediation of brand love. Based on the results, this study contributes to the approach of CSR and business ethics as distinct constructs and to the consolidation of the brand fidelity construct and its relationships. For management, this study helps organizations to perceive CSR and business ethics as important allies in a brand’s strategy. We conclude that although CSR remains important, customers value business ethics as a critical factor in their perceptions of the brand, contributing more strongly to brand fidelity.
