eCPM of $10.20 and CTR of 150%. I basically have a google search box on a "Product not found" page, in order to monetize the guys who are not going to buy anything anyway. Seems like people are searching, clicking on other ad's and then coming back to my "product not found" page. I guess they are using that page like a google home page, which is kinda funny. It's not all that exciting though...this particular channel yielded me $.02 from 3 clicks (I just started with adsense, for kicks I guess and purposefully keep the CTR low for almost all the channels. This is because the products I sell make me a LOT more money than adsense ever could., All my channels and tens of thousands of page views are yielding me less than $20/day through adsense, while I make about $6K/day in sales and about $700 in profits from the underlying product)
I once had 2700%, which was probably a mistake. I contacted google support and they kindly helped me to solve the issue.
