I like template #1. But the negative is the adsense placement in the sidebars and the header.
#2 has much better adsense placement!
I made this template for my AdSense site so that it will be cleaner and slightly more attractive and still be good for CTR.
Biodegradable Sunscreen - Learn about Biodegradable Sunscreen and Biodegradable Sunblock <-- Current/Old Template
http://biosunscreen.net/wp/ <-- New Template
What do you think? My main priority is clicks over readership (for this site, revenue is #1), but I feel the current/old template is a little too spammy that its counterproductive.
PS: Some people don't like the colors that I've talked to. The colors are easily switchable, and I'd love some ideas for color palettes if you have any.
