Abstract: A method includes, but is not limited to any combination of: determining a plurality of third-party content elements based in part on information associated with a request for third-party content. The request for third-party content may be received from a web browser displaying a first webpage to a user. A first element from the plurality of determined third-party content elements is transmitted to the web browser. Upon receiving from the web browser a second request for third-party content including user interaction data with the first element, data associated with the determined plurality of third-party content elements is updated based at least in part on the user interaction data. A second third-party element from the plurality of updated third-party content elements is transmitted to the web browser.

Abstract: A method and system provide, using a microprocessor of computing device associated with a web publisher, content including a web page. The method includes accessing, by the web publisher, a list including at least one extension associated with a web browser rendering the content at a second computing device, and a key generated based on the content, the key being generated at a specific time after the providing. The method includes comparing a value associated with the key to an expected value to determine a difference between the key and the expected value.

Abstract: Mobile device application usage history is collected across a plurality of mobile device applications. A mobile device application usage trigger event is received. For each of a plurality of candidate push notifications, a quality score adjustment is determined as a function of the collected mobile device application usage history and the trigger event. An opportunity to push a notification to the first mobile device is auctioned based on the adjusted quality scores. The notification of the auction winner is pushed to the first mobile device.

Abstract: A system includes a processor configured to execute a web browser in a first browser execution process initiated by an operating system of the system. The system includes a browser extension installed in the web browser, the browser extension including a markup language file and a file specifying at least one type of action related to a page element on which the browser extension seeks to act. The web browser may be configured to receive a set of rules from a web publisher associated with a first web page prior to rendering the first web page, determine based on the file, without loading the browser extension, that the browser extension is configured to implement a first action prohibited by the set of rules, and restrict the browser extension from implementing the first action on the first web page.

Abstract: Systems and methods for identifying and exposing content element density and congestion are provided. A descripted method includes injecting a measurement object into published content. The measurement object is configured to automatically measure a clutter attribute of the published content and to generate a clutter metric for the published content based on the measured clutter attribute. The method further includes receiving the clutter metric from the injected measurement object, storing the clutter metric in a clutter statistics database, receiving a notification of an available impression for presenting a third-party content item in conjunction with the published content, exposing the available impression to one or more third-party content providers, and providing the one or more third-party content providers with a quality score for the published content. The quality score is based at least partially on the clutter metric for the published content.
