Hi I'm Mel. I have tried running an experiment with adsense ad placements, colours, different sizes, text and picture ads. Here's what happened:- Firstly my sites ads were very much the same as on this page http://www.hartlepool-visitor.com. And for the most part got ignored. I tried changing sizes and colours to a slight improvement with CTR. Then I started blending ads into my text using tables both pic and text ads using my ads as the visual point of the sites page e.g. Website Traffic. The results are fantastic so it just goes to show that it's always best to experiment with adsense until the results start to come in. FREE VIRAL TRAFFIC
