New guy in need of some advice from the experts

Hello, I am new to this forum and just was wondering if someone could check out the placement of the Google Adsense on my website?

Some things I have to say first,

I just recently (few hours ago) placed the Adsense on my site because the site was created afew hours ago and I am planning on adding more content.

I'm apperently doing something wrong because I've read all of Google Adsense's help, scoured the internet for Adsense tips and hints/secrets and have only made an accumulative total of $16.50 using Adsense within the past year on a domain I register'd a while back. Also, I've never been good at all with generating traffic to my site, I used Overture but it only generated visits, out of 700 people who visted my site in one day I only got 2 clicks? Can someone give me some real help please? I'd really like to atleast get a nice flow of clicks going even if its only a couple cents here and there.

Thank you

 

I would prefer an-in content block rather tahn having 2 skyscrapers on either side.

 

Ok but if I am using tables and cells does it matter if the Adsense ad is in a different cell?
