Ok I see a lot of posts up here asking about traffic. I first checked the website and went straight over the ads they just didnt catch my eye then when looking around i saw them right at the top. There was a hotspot sheet out there I think reccommended by google of where the best places are to post you ads which I think was rubbish. From my own tests I have found that ads at the very top horizon dont get hardly any clickthroughs and the smal ad box at the top left aswell. For example if you were to have one medium square ad box blended in to the middle of your screen I could probably guarantee that you will get more click throughs than before. Run some tests and see for yourself.
Your ad placement look ok. I suggest you try to get some more traffic. Traffic = $$$ Build lots of backlinks. Try to improve your search results ranking.
My blog receive more than thousand impressions everyday. around 10-15 clicks and earning somewhere between $0.5 - $3.0 everyday. Is it ok?
