If your getting 0-5% click thru then this is the area I would look at the most, way more so than how much I'm making per click.

Also if you have more than one ad on a page the first lot of terms displayed will have the highest cost per click, the next set of AD's show will have less and so on.

Many many times I have seen webmasters who have there pages setup so the 2nd or 3rd group of banners get the most clicks, with AdSense your just stealing money out of your own wallet by doing this. One per page fold is enough.
