I played with it for about a month on one of my TGPs which has pretty decent traffic from Google. At first I tried redirecting directly to a sponsors site. In a few days my Google traffic was down by 80%. The traffic picked up once I removed the redirect.
Then I created a mobile landing page on a sub domain and kept redirecting to the landing page for about 2 weeks with no changes in SE traffic. Now I'm using a white label created by
TopBucks on a sub domain of one of my sites and am happy with the results. Gonna get the guys create mobile white labels for all of my sites now.
