Can a custom search engine with adsense for search be smartprices? Because my CPC go down to %40. So I Created a new adsense for search, and using both them in my website, the new has much better CPC while there is no difference between both them. Also another question, can a website be smartpriced, or only some channel. I mean in the same website, if channel earning go down because smart price, can I just change the channel and show the new one ?
