Responsible customers are becoming increasingly important and the influence of online user-generated content on consumer behavior has been extensively recognized. As a result of these two trends, social media sites are adopting new initiatives on Corporate Social Responsibility (CSR). In the context of tourism destinations, this paper analyses the effects of online comments made by visitors to two mountain resorts about three CSR dimensions: environmental (ENV), sociocultural (SOC) and economic (ECO). Our aim is to analyze the consistency of the effects of eWOM about a single CSR dimension (ENV, SOC, ECO), two CSR dimensions (ENV+ECO, ENV+SOC, ECO+SOC) or three CSR dimensions (ENV+ECO+SOC), in the impact of CSR dimensions on information adoption. Information adoption refers to eWOM perceived usefulness (PU) and perceived influence (PI). PU refers to what extent the information in the eWOM is useful and, in turn, tourists are more likely to adopt it. PI means to what extent consumers’ perceptions of eWOM affects decision-making processes. From an information processing point of view, it is important to analyze whether individuals maintain consistency in their preference for CSR dimensions. Transitivity has been used to measure consistency in product, so it could be applied to measure the consistency of the preference for CSR dimensions, presented singly or combined, on social media sites. Transitivity implies that consumers have a welldefined hierarchy of influence. If there is transitivity, it is expected that, given a set of CSR stimuli, its influence on PU and PI will be consistent. Thus, if the influence of dimension D1 is greater than that of dimension D2 and this, in turn, has greater influence than dimension D3, then D1 must have greater influence than D3. Consequently, we propose the following hypotheses: H1: The hierarchy of influence of online comments on (a) PU and on (b) PI is the same if the comment is about a single CSR dimension or two CSR dimensions. H2: The hierarchy of influence of online comments on (a) PU and on (b) PI is the same if the comment is about a single CSR dimension or three CSR dimensions. H3: The hierarchy of influence of online comments on (a) PU and on (b) PI is the same if the comments are about two CSR dimensions or three CSR dimensions. A within-subjects and between-subjects experiment was carried out to a sample of 612 tourists from Argentina and Spain. Participants were exposed to one of seven scenarios linked to a mountain tourism destination. Each scenario contained one, two or three online reviews related to CSR dimensions. The online comments resembled a typical TripAdvisor layout and were embedded in an online survey, which also contained measures of PU and PI. Our findings suggest that, of the reviews, environmental are the most useful and influential, followed by sociocultural. This hierarchical pattern is consistent when tourists are exposed to online comments about two or more dimensions, but not when comparisons are done between individual dimensions. Our findings suggest that consistency of the consumer's preference for CSR dimensions should be managed in analyzing multiple stimuli on social media sites.
