This paper presents results of an extensive long-term click-stream study of Web browser usage. Previous findings from seven to thirteen years ago are updated, focusing on cha¬rac¬ter and challenges of page revisitation. Results indicate the need for a more differentiated notion of the term page re-visit. The recurrence rate, commonly used as a key measure for the share of page revisits, turns out to be strongly dependent on interpretation. Although in average, recurrence rates in this study are lower than in previous studies, we identify types of revisitation that allow to assess the quality of current tool support and develop concepts for new tools. Individual user navigation strategies differ dramatically and are strongly influenced by both personal habits and the type of sites visited. Based on our analysis of user action logs and interview results, short-term revisits (backtrack or undo) are differentiated from medium-term (re-utilize or observe) and long-term revisits (rediscover). We analyze current problems and provide suggestions for the support for different revisitation types.
