Social Context for Content from Systems External to a Social Networking System

摘要

A social networking system provides an instruction that a third-party system may include in a web page or other content. The instruction includes information identifying content presented by the web page or other content specified by the third-party system. The information identifying the content presented by the web page is communicated to the social networking system. Based on the information identifying the content, the social networking system determines a social context for a viewer of the web page. The social context may be selected to optimize for a particular conversion event.
