<p>The serving of one or more ads to a user device considers determined characteristics of a user device, such as whether or not the user device supports telephone calls. At least some ads may include call-on-select functionality. When such an ad is selected (e.g., via a button click), instead of loading a document (e.g., Web page) for rendering, a telephone number associated with the ad by an advertiser can be automatically dialed.</p> |
