Time to recall site structure was the number of seconds it took users to draw a sitemap.

A related measure, sitemap accuracy, was a percentage score based on the number of pages (maximum 7) and connections between pages (maximum 9) correctly identified, minus the number of pages and connections incorrectly identified.

Subjective satisfaction was determined from participants' answers to a paper-and-pencil questionnaire. Some questions asked about specific aspects of working with the site, and other questions asked for an assessment of how well certain adjectives described the site (anchored by "Describes the site very poorly" to "Describes the site very well"). All questions used 10-point Likert scales.

The subjective satisfaction index was the mean score of the following four indices:

• Quality of the site comprised four items: accurate, helpful, useful, and the question "How satisfied are you with the site's quality of language?"
• Ease of use of the site comprised five items: easy to use, and the questions "How easy is it to work with the text in this website?", "How easy is it to find specific information in this website?", "Compared to what you expected, how quickly did the tasks go?", and "How hard was it to concentrate on searching for information (because of distractions)?" (this item was reverse-coded).
• Likability of the site comprised six items: entertaining, interesting, likable, engaging, fun to use, and boring (reverse-coded).
• User affect comprised three items (all reverse-coded): "How tired do you feel right now?", "How confused did you feel while working in this site?", and "How frustrated did you feel while working in this site?"

For each index, the items were averaged so that the possible range was from 1 to 10.
