Google has launched Mobile ValueTrack for advertisers to track clicks on mobile devices. "The ValueTrack parameter has long allowed you to track the clicks that you get via search and the Google Display Network separately," says Miles Johnson with Google's Inside AdWords crew. "We know that many of you would like to be able to see the clicks you get from mobile ads separately as well." The new mobile version works the same way as the other, adding a tag to the site's URL.
