The document discusses three key strategies for evaluating website usability: 1) use a theoretically based approach, 2) use qualitative "micro" research methods to understand individual user experience, and 3) use quantitative "macro" research methods to understand overall user experience. It then provides details on a case study of a health website evaluation using these strategies, including qualitative user interviews and eye tracking, and a quantitative survey adapted from a theoretical framework. The evaluation provided insights into individual usability issues and an overall user experience measure.
