Usability and credibility of e-government websites

Abstract Albeit e-government has seen a steady growth, it can still benefit from a better user engagement, and usability and credibility are believed to be among the factors that influence such engagement. This paper presents an empirical study that evaluates the usability and credibility of current e-government websites and looks at user performance while using these websites. The study is based on a heuristic evaluation which aims to capture users' perception of usability and credibility. Our results show a close correlation between usability and credibility, as e-government websites with a high usability were perceived as having higher credibility, and vice versa. A number of usability and credibility weaknesses were identified on our sample of e-government websites.
