It’s called Smart Ads and they are new from Yahoo. But don’t get too excited yet, they are not for the Yahoo Search Marketing pay per click program. Smart Ads are for the content network and are image ads. So sorry but if you want to show ads with demographics, you will have to move to MSN adCenter or wait and see if Yahoo will move this new technology into its pay per click program in the future.
