Abstract: Methods and systems for displaying content items on an information resource include identifying a supplemental content item to append to a DOM tree of the information resource and identifying a first content item displayed in a first container of the information resource. The methods also includes monitoring a position of a predetermined portion of the first content item relative to a viewport of the application and determining, responsive to monitoring the position of the predetermined portion of the first content item, that the first content item is visible within the viewport of the application. The method also includes appending the supplemental content item in a second container at a first position between the first container and an end of the information resource and displaying the supplemental content item within the viewport of the application responsive to detecting a scroll action towards the end of the information resource.

Abstract: Methods and systems of reducing computer resource utilization to update rankings based on dynamically generated content are described. The method includes identifying a ranking of content experience types of a list of content experience types. Each content experience type including parameters to generate content experience documents. The method also includes updating the ranking of content experience types. The updating includes iteratively selecting content experience types from the ranking of content experience types to generate an update subset of the ranking of content experience types, generating, for a client device, a feedback request document including a plurality of content experience documents, and receiving feedback information related to the plurality of content experience documents included in the feedback request document to update the ranking of the content experience types included in the update subset.

Abstract: Systems and methods for suggesting a bid adjustment value based on device type include receiving parameters for a third-party content provider's campaign to present third-party content on a first type of device. Based on the campaign's parameters, bids from peer providers that use similar campaign parameters for both the first type of device and another type of device may be identified. For example, bids from providers that use similar parameters as the campaign for both mobile and desktop devices may be identified. The identified bids from the peer providers may be used to calculate a bid adjustment value. The bid adjustment value can be provided for presentation to the third-party content provider as a suggested change to his or her bid for the first type of device, to establish a bid for the second type of device.
