Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for collecting and applying visibility statistics in online advertising are disclosed. Ad block visibility data relating to initial visibility characteristics and subsequent visibility characteristics of ad blocks on webpages are collected from a sample of browser sessions and aggregated to provide a representative historical view of ad block visibility characteristics on those webpages. The collected visibility data are used to build a predictive model of ad block visibility characteristics for future sessions. Ad selection can be based on the predicted visibility characteristics for ad blocks on a webpage as rendered on a particular requesting client device. Ad targeting and pricing can be specified in terms of predicted visibility characteristics of ad blocks.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for measuring lift. A method includes: receiving requests for content for which a first content item is an eligible content item; delivering the first content item along with a first pixel that identifies the delivery of the first content item to a first portion of the received requests; delivering a second, different content item along with a second pixel that identifies the non-delivery of the first content item to a second portion of the received plurality of requests rather than the first content item; evaluating searches performed by users that received the first content item as compared to users that received the second content item including using the first pixel and second pixel in evaluating search logs associated with search requests performed by users; and presenting lift data to a sponsor associated with the first content item.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, for presenting content associated with a landing page. A method includes: receiving a request for content to be published along with third party content in a resource; identifying a content item responsive to the request, the content item including a link to a landing page and an indicator for designating the content item as a swappable content item, wherein a swappable content item enables navigation away from the resource to the landing page without losing state of the resource, the content item being configured to monitor interactions of the user and inhibit a direct loading of a landing page in favor of a simultaneous presentation of the content of the landing page in a container having an overlay that includes the resource; and providing the content item including the indicator responsive to the request.

Abstract: Systems and methods of providing information via a computer network are provided. A request for content to display with a resource can be received via a computer network at a data processing system. The request can include user information and resource information. The data processing system can retrieve a timestamp of a last request for content from a user associated with the user information. The data processing system can determine if a difference between current time and the timestamp reaches a threshold, and can retrieve a plurality of content items based at least in part on whether the threshold is reached and at least one attribute of the content items. The data processing system can select at least one content item and provide it for display with the resource. The data processing system can store the current time as the timestamp of the last request for content from the user.

Abstract: A computer system that finds an optimal sequenced route through one point from each of a plurality of categories. The routes are found by determining one point from each of the categories and finding the shortest path through the one point through each of those routes.
