Socially Augmented Browsing of a Website

A computer system enables users of an Internet application (such as a web site or a mobile application) to specify that they wish to be members of one or more groups. The computer system provides the user with information about activities performed by other users who are members of the same group as the user. For example, the computer system may inform a user of the web pages currently being viewed and/or recently viewed by other users who are members of the same group(s) as the user. Examples of other information that the computer system may inform the user about include amount of time spent by other users in the same group on particular web pages, content shared by those users, and products purchased by those users. Groups may be created by the users themselves and/or by the administrators of the Internet application.
