The aim of the present study is to propose a model to examine the relationships among social Website interactivity, brand experience, brand choice, and behavioral intentions in the context of online travel agencies brand websites, as well as to examine the ultimate moderating role of the age of the traveler in the dynamic of this model. Drawing on website interactivity and brand development theories, current research suggests that the inclusion of social website interactivity in the design of online travel agencies brand websites helps to directly and indirectly create a positive brand experience and to enhance the perception of online travel agencies brand websites as valuable. These perceptions may consequently impact the behavior of travelers to pay higher prices and to continue buying from the online travel agencies brand websites. However, while this existent research mostly considers the positive and causal relationships among the aforementioned constructs, there is also some indication that the perceptions of travelers in relation to the proposed relationships change with age, suggesting that older travelers (age above 25) may perceive distinctively the relationships among these constructs in the context of online travel agencies brand websites as compared to younger travelers (aged 18-25). The study attempts to analyze on this relevant and under-examined research topic. This research is mainly based on a sample of travelers who have used an online travel agencies brand websites in China. The empirical findings suggest that social website interactivity, brand experience, and brand choice are essential factors for travelers to be willing to pay higher prices and to continue buying. The empirical findings also suggest that the proposed theoretical framework is adequately adjusted, therefore confirming that the age of the traveler moderates the proposed relationships first between social website interactivity and brand choice, second between brand choice and price premium, third between brand choice and buying intention, and lastly between brand experience and buying intention. Overall, the theory-driven framework accomplishes an acceptable model fit. Additionally, theoretical and practical implications are discussed. Social Website Interactivity (SWI) construct is defined as the reciprocal communication between individuals and technology. Research shows that SWI exerts a positive impact on the user that eventually causes an e-loyal behavior (Cyr et al., 2010). Voorveld et al. (2009) conclude the design of a theoretical model that includes SWI and branding elements is required to brand Websites. The theory explains SWI as a branding tool and its influence on travelers’ perceptions and behaviors in the travel context. Given these findings, the authors of this study predict that OTA Websites that incorporate features of SWI may have a remarkable competence to build a brand online. Based on the given review, it is rational to expect that SWI might influence user perceptions of value and positive brand experience of the OTA branded website. A favorable experience is what reduces perceived risks when buying online and what influences users to revisit the website. Brand selection and brand experience (Morgan-Thomas & Veloutsou, 2013) are key elements to influence consumers’ behavior therefore must have a significant influence on behavioral intentions and willingness to pay premium prices. The current perception in social sciences and behavioral marketing is that age is a critical demographic variable that has direct and moderating role in the impact of interactivity and brand selection, brand selection and willingness to pay higher prices, brand selection and behavioral intentions, and online experience on behavioral intentions (Kirk et al., 2012).
