Users repeatedly visiting the same website to update information. Visits are triggered by routine behavior rather than a particular goal. Although this has been common knowledge for some time, the magnitude of the percentage surprised even me. It's also interesting that it is almost three times as important for users to find multiple pieces of information as it is to locate a single specific piece. The entire browsing paradigm is optimized for accessing individual locations.
Users are typically on their own when they want to collect more than one answer.
Evaluate multiple products or answers to make a decision. Get a fact, get a document, find out about a product, download something. The important tasks are thus divided almost equally between cases where the user is trying to decide between multiple options and cases where the user is pursuing a single option. The three Cs, collect, compare, and choose, describe most of the Web's critical use. As a result, we should make sure to include test tasks that address these issues when we plan usability studies of websites.
