Customer engagement has gained much attention in the recent literature because it has been linked with numerous brand performance indicators including sales growth, customer involvement in product development, customer feedback and referrals (Bijmolt et al. 2010; Bowden 2009; Kumar et al. 2010; Nambisan and Baron 2007; Sawhney et al. 2005; van Doorn et al. 2010). In the tourism industry, customer engagement has been found to boost loyalty, trust and brand evaluations (So et al. 2014). Customer engagement is often facilitated by social media, but neither of these phenomena are well-researched, and there is a need for practical social media recommendations for tourism organisations (Mistilis and Gretzel 2013). Social media-based tourism brands include TripAdvisor, Airbnb and Booking.com and are growing in popularity and influence (Filieri 2015). For example, TripAdvisor is the world’s largest travel review company and turned over $1.246 billion in 2014, up 32 % from the previous year and helps shape consumer preferences (Forbes 2015).
