Three senior websites with varying levels of compliance to “senior-friendly” guidelines were evaluated for efficiency and usability with older adults. Results indicate that the website compliant with the most senior-friendly“ guidelines resulted in higher task success, but did not result in significantly lower time on task or fewer number of pages visited. In addition, the site compliant with the most ”senior-friendly“ guidelines did not result in higher satisfaction or preference. The importance of adding usability testing to the website design process, especially for this target audience, is highlighted.
