The aim of this research was to investigate usability issues of websites of three entrepreneurial and innovative universities, Middle East Technical University, Koç University, Sabancı University, on mobile and desktop in Turkey. In order to figure out the limitations and differences of conducting same usability evaluation methods for mobile and desktop websites and to explore effective and effcient usability evaluation methods for mobile websites, usability evaluation methods were compared by using qualitative and quantitative data gathered from user-based and expert-based experiment. Four usability evaluation methods, eye-tracking experiment, WAMMI (Website Analysis and MeasureMent Inventory) questionnaire, concurrent think aloud technique, heuristics evaluation, were applied throughout the research. Results of the research showed that users’ satisfaction of desktop websites was higher than mobile websites. Lack of responsive design on websites, inconsistent navigation design between the main page and subpages and user interface design problems such as small size texts and unorganized structure were main mobile-specific usability problems. Results of the research also revealed that there were critical methodological differences of usability evaluation methods between mobile and desktop experiments. For instance, concurrent think aloud technique was not appropriate for mobile experiments. Besides that, mobile eye-tracker device could not record participants’ eye movements and gaze plots due to mobile experiences of participants and settings of mobile eye-tracker.
