Abstract: A method includes monitoring an activity stream to identify actions that match stored sponsored story specifications, for providing one or more sponsored stories to a viewing user. The sponsored story specifications include a visual specification for the sponsored story, and matched sponsored stories are ranked for a viewing user. Users can set privacy preferences related to sponsored stories. The ranking and privacy settings contribute to which sponsored stories are provided for display to the viewing user.

Abstract: A seed cluster comprising a group of users who share a particular attribute and/or affiliation is determined by a social networking system. For each user of the seed cluster, other users and/or entities connected to the user in the social networking system are retrieved. For each retrieved other user or entity, the social networking system may determine whether the other user or entity exhibits the attribute or affiliation based on a random walk algorithm. A resulting targeting cluster of users and/or entities may be used for targeting advertisements targeting to members. A social networking system may also infer an affiliation for a user based on the user's interaction with a page, application, or entity where other users who interacted with the same page, application, or entity have the same affiliation.

Abstract: An online system receives an advertisement request from an advertiser and determines an advertisement objective associated with the advertisement request. Validation rules associated with the advertisement request are retrieved and applied to components of the advertisement request. Application of the validation rules determines whether components of the advertisement request are consistent with the advertisement objective. A result of the application of the validation rules to the advertisement request is presented to the advertiser, providing the advertiser with a measure of the effectiveness of the advertisement request in satisfying the advertisement objective.

Abstract: A method includes receiving sponsor specifications designating story characteristics, monitoring an organic activity stream for entries matching the story characteristics, and, in response to identifying an entry as matching the story characteristics, providing for display the entry in a predetermined area of a web page.

Abstract: To provide a sponsored story unit, the social networking system receives a story request from an advertiser. The story request specifies properties of content used to generate the sponsored story. When the social networking system stores an object or an action performed on an object, properties associated with, and describing, the object or the action are also stored. For example, properties of an object include an object type, an object identifier, metadata describing the object or other suitable information. The social networking system identifies actions or objects associated with users connected to a viewing user having one or more properties included in a story request. A sponsored story is generated from the identified actions or objects and presented to a viewing user.
