Abstract: To promote an object maintained by a social networking system, an advertiser identifies the object to the social networking system. Based on the user interaction with one or more posts associated with the object, the social networking system selects one or more candidate posts from the one or more posts. Promotion efficacies of each candidate post for a group of users having one or more common demographic characteristics are determined and a candidate post is selected based at least in part on the promotion efficacies. The selected candidate post may be identified to the advertiser or presented to additional users having the common demographic characteristic by the social networking system.

Abstract: A file, including visual information or auditory information may be uploaded to a processing device. Respective portions of content of the file may be identified fin compressing and saving at respective bit rates. A number of component files may be created, compressed and saved, at the respective bit rates, based on the identified respective portions of content of the file. A network page, including a reference to the uploaded file, may be created. The reference to the uploaded file, in the page, may be replaced with references to the compressed, saved component files and the network page may be saved. A processing device of a user may request the network page and the compressed, saved component files. A reasonable facsimile of the file may be reproduced based on an aggregate of the compressed, saved component files.

Abstract: A social networking system generates an advertisement, a recommended budget, and recommended targeting criteria for an object maintained by the social networking system for presentation to social networking system users. Information associated with the object by the social networking system is used to generate elements of the advertisement, the recommended budget, and the recommended targeting criteria. Different budgets, each associated with a predicted return on investment, may be determined, allowing an advertiser to select a budget based on the return the advertiser receives from presentation of the advertisement. Additionally, an advertiser may modify the recommended targeting criteria, recommended budget, or elements of the generated advertisement to customize presentation or distribution of the advertisement.

Abstract: An online system provides identifies multiple candidate budgets to an advertiser requesting presentation of advertisements via the online system. The advertiser may select a candidate budget used for presenting advertisements via the online system. A default budget may be identified from the candidate budgets to increase the likelihood of the advertiser selecting the default budget. The candidate budgets and the default budget are determined by the online system to maximize the likelihood that an advertiser elects to present advertisements via the online system or to maximize revenue received the online system for presenting advertisements from the advertiser. Various factors are specific to the advertiser, the object being advertised, and other contextual information may be used to determine the candidate budgets.

Abstract: A social networking system allows entities to delegate actions performed on behalf of the entity to social networking system users by assigning one or more roles to social networking system users. Roles may be assigned based on information associated with the entity by the social networking system. Different roles are associated with sets of permissions specifying actions a user associated with a role is authorized to perform on behalf of the entity via the social networking system. Certain permissions of a role associated with the user may be associated with additional users by the user. A persona including a subset of information associated with a user by the social networking system may be created for a user assigned a role, allowing the user to limit information accessible to additional users connected to the persona.
