Swebbie, it's funny you mention that.

My articles used to contain 2 adsense blocks. I have since replaced the bottom (lower paying AS block) with the Chitika block.

The CTR for my top AdSense block went up 30% (of course Smart Pricing killed any extra income) but the Chitika block below is blowing the old bottom AdSense block out of the water... generally about 5x more revenue.
