This study investigates and critiques existing Type 2 Diabetes Mellitus (T2DM) websites for usability concerns and provides design recommendations to improve it. A web search for T2DM and diabetes education based on Alexa and Google provided the basis for the study. A discounted usability evaluation technique, heuristic evaluation was applied. The heuristic evaluation resulted in 12 usability issues for American Diabetes Association (ADA) website; 11 usability issues for WebMD; and 15 usability issues for National Diabetes Education Program (NDEP) website. The top five usability problems were presented and discussed in detail. The site that had the best usability was ADA. Findings from this study will be essential for future research to assure that users have a great user experience with T2DM information websites and gain meaningful and relevant information on how to prevent the disease.
