Explain how usability testing can be performed without working directly with the users of a website.?

What will be an ideal response?

?Usability testing can be performed without working directly with the users of a website through the use of questionnaires or surveys. Open-ended or scaled survey questions should be written to elicit information. For instance, asking the yes or no question "Is the website visually appealing?" will not gather especially useful information. If a user answers no to that question, the developer will not know how to improve the site to make it more appealing. Even if a user answers yes, the developer will not know how much appeal the website has. If this question is changed to use a scaled response, such as "Rate the visual appeal of this website, using a scale of 1 for low and 5 for high," one can get more valuable input from the users. However, one should make sure that the scale itself is clear and understandable to the users. If the developer intends that a selection of 1 equates to a "low" rating but the users think 1 means "high," then the survey results are questionable. Another way to ask for design feedback is to list parts of the site, such as graphics, sidebars, and navigation, and ask users to select the parts that are appealing to them. In addition, the developer can provide space on the usability testing questionnaire where users can write comments.
