If a site had no mission statement, use your own judgement based on expectations. Depth of Content. How easy is was to locate and go to independent items at a given site. Intelligent layout of pages so that you are not overwhelmed with choices or information. Accuracy, in this case, is a measure of how well a site assures you that the information or service it provides is credible.
Some sites are so busy that it is sometimes difficult to connect.
Others place a limit on how many people can connect at a time. If you have trouble connecting to a site, try it several times to establish a pattern. You might think of this criterion more generally as aesthetics. Evaluators considered not just the visual appeal, but the appeal to the mind as well. Because it is so difficult to determine the exact cause of good or bad performance, use this criterion only as a modifier.
