Among these criteria, ease of use measures the ability of website visitors to easily navigate and access the information they want; corporate information criterion measures the accuracy and comprehensiveness of the information provided about the business; page content measures the diversity and comprehensiveness of the information contained in the website; and routing criterion measures the ability of the website to direct users to other pages or content.
