“…Therefore, eWOM and user-generated contents (UGC) emerge as key drivers for consumers' buying decisions (Gensler et al, 2015;Lee et al, 2012). For these reasons, a large body of literature investigates the effect of eWOM on sales (King et al, 2014), other authors tried to identify the effect of positive or negative online comments/posts/reviews (Hornik et al, 2015;Li et al, 2013;Pang and Qiu, 2016;Yang et al, 2015), the best strategy to influence consumers' positive eWOM (Erkan and Evans, 2016;Reamer et al, 2016), consumers sentiments towards a certain brand (Mostafa, 2013); and consumers' reactions towards the firm's participation in their online conversations (Homburg et al, 2015), while other studies have further considered using online consumers' rates of tourism attractions as predictors of their future behaviour . Thus, the online contents generated by consumers in terms of reviews, ranking and ratings largely convey more information than reputation, in other words they reflect the product quality and popularity of a certain product, brand or service (Li et al, 2013;Liang et al, 2015;Tsekouras, 2017).…”
