Abstract: Dynamic web page generation is optimized by reducing the processing overhead required to parse the web page HTML code for tokens and insert dynamic content. Using the invention, an HTML file for a dynamic web page need be read and parsed only once throughout the life of the server. A software object parses the HTML, decomposes the page into constituent pieces and saves them to data structures as byte streams, which are cached, along with the software object, rendering multiple disk accesses unnecessary when the page is reconstituted. For subsequent requests, the dynamic page is created from the cached version, which is shareable across users and across requests. The optimization reduces server resource usage for dynamic page generation to near zero. The invention is also applicable to other documents combining static and dynamic content that require composition tools for editing.

Abstract: An online system applies position discounts to values of various content items based on the positions in a display in which the content items are presented. The value of presenting a content item is based on historical user interactions with the content item or similar content items. A position discount reflects a change between user interacting with a content item presented in a position offset from a reference position and user interaction with the content item if it was presented in the reference position. A position discount may be determined for various content items presented in one or more positions based on user-specific, contextual, and other types of information describing user interaction with content items. Position discounts may be used by the online system to optimize selection and presentation of content items to its users.

Abstract: An online system enables developers of third-party applications to specify online system users to receive advertisements. The online system generates and sends a user-specific identifier for online system users that use a third-party application when an advertiser associated with the third-party application requests a user-specific identifier from the online system. For example, the online system retrieves user identifying information associated with a client device identifier provided by an advertiser and generates a user identifier by encrypting the retrieved user identifying information. The advertiser may include one or more user-specific identifiers in an advertisement request sent to an online system to present an advertisement in the advertisement request to online system users corresponding to the user-specific identifiers.

Abstract: Based on prior interactions associated with a user, an online system predicts an amount of interaction by the user with an object associated with an advertisement. Using the predicted amount of user interaction, the online system determines an expected value of presenting the advertisement to the user. The advertisement is ranked among other advertisements based on the expected values associated with the advertisements, and one or more advertisements are selected for presentation to the user based on the ranking. An advertisement may also specify a threshold amount of interaction with an associated object as targeting criteria, so the predicted amount of interaction with the object associated with the advertisement may determine if a user is eligible to be presented with the advertisement.
