Someone did it? I've seen before Addwords adds that leads to Addsense pages and that always bothered me how this could work. Untill I heard about "Adsense Arbitrage". People buying cheap keywords and redirect traffic to related, highly payed ones (having ads with highly payed related keywords). Seems like lot of analytic work to be done for that and some serious risk involved. It makes me wonder what is the CTR for such pages.
