Determining browsing activities is described. In one or more implementations, browsing history data, indicating navigation to websites using a web platform, is analyzed to determine a browsing activity, such as shopping, planning a trip, and so forth. The websites navigated to using the web platform as part of the browsing activity are then stored with the browsing activity to enable subsequent access to the websites. In one or more implementations, for each browsing activity, one or more suggested websites which are related to the browsing activity are determined and stored with the browsing activity to enable access to the suggested websites.
