Abstract: An online system generates a feed of content items for a user subject to a limitation restricting the number of content items including video data (“video content items”) included in the feed. If the user interacts with a video content item the feed, the online system selects candidate video content items based on characteristics of the video content item in the feed and characteristics of the user. The online system determines likelihoods of the user interacting with various candidate video content items and selects candidate video content items based on the determined likelihoods. To present the user with additional video content items, the online system generates an interface including the selected candidate video content items and presents the interface to the user. The interface may be presented in place of the feed or may be presented as within the feed and presents different video content items based on user interactions.

Abstract: An online system provides an advertisement (“ad”) request including ad content and a prompt to perform an action presented in association with the ad content. For example, the ad content is video data and the prompt for performing an action is presented after the video data is presented or after a portion of the video data is presented. An advertiser may include a custom prompt in the ad request that includes text information and instructions associated with the text information that perform an action when executed. Multiple prompts may be included in the ad request, and the online system selects a prompt based on information maintained by the online system and associated with a user to be presented with the ad content. The selected prompt is communicated to a client device for presentation in association with the ad content.

Abstract: An online system allows an entity to generate a content item having multiple states, with each state including different content. When a user interacts with the content item, a different state of the content item is identified and content associated with the different state is presented to the user. For example, if the user contacts a portion of a display device presenting the content item, content from a different state of the content item is presented. If the content item is an advertisement request, the online system may charge the entity an amount depending on whether content associated with various states of the content item was presented to a user.

Abstract: An online system allows an advertiser to specify an advertisement (“ad”) request including information describing multiple products, where one of the products was previously presented to a user of the online system to be presented with the ad request. The additional products included in the ad request are selected based on a measure of their relevance to the product included in the ad request. An advertiser provides the online system with an identity of the user and the product previously presented to the user. The one or more additional products may be specified by the advertiser, may be selected by the online system from a product catalog of the advertiser, or may be selected based on their relevance scores with the product previously presented to the user.

Abstract: An online system sells fixed-price advertising guaranteeing a number of impressions or a number of actions associated with an advertisement by users of the online system. The price for an advertisement associated with a guaranteed number of impressions or actions is based on a target bid amount for selecting the advertisement from a group of advertisements using a conventional pricing scheme and a predicted likelihood that the guaranteed number of impressions or actions occur. The price may be further adjusted by a premium that accounts for a risk of revenue lost by the online system for displaying an advertisement associated with a guaranteed number of impressions or a number of actions rather than conventionally-priced advertisements.

Abstract: An advertisement interface receives an input identifying an object maintained by or otherwise accessible to a social networking system. A type associated with the object identified by the input is determined and one or more goals associated with the type are presented. Based on selection of a goal, one or more options are presented, where at least one of the presented options is associated with the selected goal. Hence, goals specific to a type of object may be presented and options specific to a selected goal are presented to increase advertisement effectiveness. Based on the selected options, an advertisement is created and displayed to other users of the social networking system.
