An SSO provider—i.e., a provider of user accounts that a number of other online services accept as a sign-on technique—identifies the online services to which its users sign on, as well as the digital content items that those users access. The SSO provider uses this information to associate particular content items with particular online services, or combinations of online services. The SSO provider can then use the associations to make recommendations of content items to users based on the services to which the users have signed on. |
