A social networking system uses information that it obtains from and about its users to select social networking content and advertising for presentation to users in a way that optimizes for one or more optimization goals. Example optimization goals include monetization, user sharing, user engagement, system growth, and user communication. The social networking system may select social networking content and advertising based on their relevance to a particular user. The selected social networking content and advertising may be related to each other to provide a more interesting display to the user. The selected social networking content and advertising may be presented in a supplemental portion of a display, and be selected based on their relatedness to content in the main portion of the display.
