The e-commerce industry in India has seen unprecedented growth in last few years. Eyeing India's substantial e-retail opportunity across multiple segments, investors have been aggressively funding the e-commerce sector. This growth has been fuelled by rapid adoption of technology, improving standards of living, an increasing young population, and economically advancing middle class, besides increasing access to the Internet through broadband and use of smartphones and tablets. The entry of global e-commerce giants has intensified the competition for home-grown players. E-retailers use web atmospherics to differentiate themselves from their competitors and evoke positive cognitive and emotional states of online consumers. However, though this Indian online market is growing at an exponential rate, it is still unexplored in terms of its shopping behaviour. Using structural equation modelling, this study applies the concept of the stimulusorganism-response to explain Indian buyers' online shopping behaviour, besides examining the importance of design elements in enabling website satisfaction (WS). Using a survey method to test the research model, primary data were collected from five Indian metropolitan cities of Delhi, Mumbai, Kolkata, Bengaluru, and Hyderabad during the months of May and June 2015. Confirmatory factory analysis (CFA) was used to estimate the measurement model with respect to convergent and discriminant validities. This was followed by testing the structural model framework and research hypotheses. Findings suggest that both internal and external elements have direct influence on WS. As the mediating variable, WS affects purchase intention. This research highlights on why and how 'satisfaction with website' matters in the contribution of shopping values and website atmospherics to behavioural outcomes by presenting its mediating role.
