Abstract: When a client device loads a resource, a request for a first content item for a first content item slot is transmitted to a content item selection system. The content item selection system uses a predictive model to determine a predicted content item slot based on a document object model position of the first content item slot and a URL of the resource or a publisher identifier. Parameters for the predicted content item slot are used to select a subsequent content item for the predicted content item slot. The first content item and the subsequent content item are transmitted to the client device responsive to the request. The subsequent content item includes metadata indicative of the parameters of the predicted content item slot to be matched to a subsequent content item slot of the resource.

Abstract: In embodiments, application data is received from multiple application platforms. Once received, an object mapping is used to determine a synchronization data object that is mapped to data objects from the application data. A function mapping is used to determine one or more functions to apply to the application data. Data objects from the application data that are mapped to the synchronization data object are compared to detect conflicts between fields. In response to detecting a conflict, the conflict is resolved based on configuration rules that indicate priority between fields of different data objects. Once the conflict is resolved, the data objects are merged into a modified synchronization data object that represents an updated version of the synchronization data object. Changes between the synchronization data object and the modified synchronization data object are identified and propagated to application platforms to perform updates to application data managed by the application platforms.
