The purpose of this study is to explore the relationship between website quality and customer's behavioural intention across search, experience and credence goods/services. After conducting an empirical study in Taiwan, website quality consists of five important factors: connectivity, information quality, interactivity, playfulness, and learning. The results of this study suggest that the factors of connectivity, interactivity, playfulness, and learning have positive impacts on customer's behavioural intention for search goods/services. Connectivity, information quality, and interactivity are helpful to strengthen customer's behavioural intention for experience goods/services. However, only information quality and interactivity are significant to improve customer's behavioural intention in credence goods/services.
