Abstract: A social networking system that allows a user to host a page for a pre-launch product that transitions to a post launch page. In some cases, the pre-launch page may be accessible to the users of the social networking system to provide information and data associated with the pre-launch product. In some cases, the pre-launch page may be configurable such that when the product launches, the page converts to a post launch page at which the product may be purchased.

Abstract: An online system receives a content unit identifying a set of content items each associated with a physical location. Different content items of the set include different content associated with different physical locations. When the online system selects content from the content unit for presentation to a user, the online system selects a content item of the set identified by the content unit based on physical locations associated with the content items and characteristics of the user maintained by the online system. For example, the online system selects a content item of the set associated with a physical location having a minimum distance to a location associated with the user by the online system. Rules associate interactions by the user with content from the content unit with an object associated with the content unit or with another object associated with a selected content item of the identified set.
