Abstract: Techniques for affecting display of content may include receiving a request for content to supplement a response to an input initiated by a first user; outputting first content in response to the request, where the first content includes a control feature that is displayable along with the first content, and where the control feature enables the first user to register a negative reaction to the first content; obtaining information relating to the first content based on the negative reaction; identifying second content having one or more characteristics in common with the first content; identifying one or more second users having one or more characteristics in common with the first user; and using the information relating to the first content in determining whether to provide the second content to the one or more second users.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for computing an optimal font-size for text in a content item. In one aspect, a method includes receiving a request for a content item, identifying a content item eligible to fulfill the request, the identified content item including text, initializing a set of constraints for rendering the identified content item, based on the initialized set of constraints, determining an optimal font-size for rendering text included in the identified content item, and delivering the identified content item and an indication of the determined optimal font-size to a device for presentation.

Abstract: Systems and techniques are described for advertisement retrieval and display formatting. A described technique includes receiving a request associated with a website to retrieve advertisement content for display within a frame of a display of the website, the request including dimensional values defining dimensions of the frame; obtaining advertisement display parameters that control display of content within the frame; determining a maximal quantity of advertisement content units that are fully displayable within the frame based on the dimensional values and a plurality of different combinations of the advertisement display parameters, obtaining advertisements based on the determined maximal quantity; and providing the obtained advertisements for display within the frame.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, for providing a method for re-publishing content that is provided by a content publisher to a user. A method includes providing an advertisement for display to a user in a slot, the advertisement including a first annotation providing information for or about re-publishing the advertisement; receiving a request to re-publish the advertisement to one or more individuals or groups associated with the user in a social context; and providing the advertisement as part of an activity stream for a social application, including presenting the advertisement in the activity stream for the user.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, for providing a user interaction point on a user device in conjunction with content that is provided by a content publisher. A method includes receiving a request for an advertisement to be displayed in a slot associated with a third-party content site; identifying a relevant advertisement to be provided in the slot; determining information to be included in an annotation associated with the advertisement, the annotation including customized information related to the user or a group associated with the user; and providing the advertisement responsive to the request including providing the annotation for presentation along with the relevant advertisement.
