Within online retail, the excellence of customer experience is not only mediated through a compelling online experience, but also other traits associated with usability and willingness to engage with the website. That is, performing online transactions also presumes that a consumer perceives a website to be both easy to use, reliable and trustworthy. This emphasizes an online store in terms of consumer’s perceptions about its usability and trust. Relating to this, the current study aimed to discover the influence of perceived website usability on trust of online stores. First section of the thesis, implemented as a literature review, inspected the relationship between user experience and customer experience. Based on the literature, user experience may be considered influential to customer experience through perceived customer value. Basically, the more value-in-use experienced along with highly estimated website quality may enhance consumer’s overall experience about an online store. The second section of the thesis, instead, focuses on inspecting factors related to website usability and trust via an online survey. The data (N=318) was collected in March 2018 from both students at the University of Jyväskylä and other online store users. The results gained from the survey confirmed the relationship between perceived website usability and online store trust. This relationship was especially valid in terms of aesthetic formality. The results gained may be utilized when designing customer experience in online stores. For one, the results offer insight into consumers’ meaning-making of online stores’ website usability. Further, they may illustrate those website attributes of usability and aesthetics which are reflected against the evaluation of an online store’s trustworthiness.
