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.
