Usable guidelines for usable websites? An analysis of five e-government heuristics

Many government organizations use web heuristics for the quality assurance of their websites. Heuristics may be used by web designers to guide the decisions about a website in development, or by web evaluators to optimize or assess the quality of an existing website. Despite their popularity, very little is known about the usefulness of heuristics for web designers and evaluators.
