The interconnected nature of today’s online platforms, specifically social media and websites, has made seamless experiences across social media and websites crucial to the visibility and memorability of brands. This study investigates user perceptions of different levels of visual consistency between an e-commerce user interface and social media content on user experience and trust. A dedicated e-commerce website was developed for a fictitious brand, along with content for three different social network accounts, each designed with varying degrees of visual consistency towards the website’s user interface. Participants were divided into three groups, with each group interacting with one of the accounts and the website to examine how cross-platform visual consistency influences users’ perception of trust, navigational ease, and intentions to engage. The study combines usability testing, semi-structured interviews, and thematic analysis to capture both behavioral and cognitive user responses across these groups. Findings suggest that the perceived visual consistency promotes greater trust and navigational ease, leading to a more positive user experience. Conversely, perceived inconsistencies between platforms can disrupt user expectations and diminish the credibility of a brand.
