Systems and methods of providing information via a computer network are provided. A data processing system can obtain, via the computer network, a request for content. The request for content can include a keyword. The data processing system can identify a content item responsive to the request for content based at least in part on the keyword, and can identify a match between a format of the content item and an input format of the request for content. The data processing system can assign a weighting factor to the content item based on the match, and responsive to the weighting factor can select the content item as a candidate for display at a computing device.
