My site is about to be released soon, and the link above is a preview.
I would like to know if you think the ads are well place to earn me the maximum amount possible.
Hard to know for certain since different sites have different users who respond differently. Your best bet is to test and see. Looks like you've covered the basics. I don't know how well the vertical ads on the right work, but the ones on the left and the top have usually worked well for others.
I've found ads embedded within the content have worked best for me for the ads I've tried, but I think much is dependent on the specific site.
I'd be inclined to say "no", just because you're running 3 AS blocks. Each block after the first tends to generate lower-paying ads than the one before it, so if people are clicking on your third ad block, you're gonna get bugger all in return.
However, that's one you'd really have to test and measure. Use the Adsense channel tracker by putting a channel ID code for each of those ads to see which group pays off the most (I bet you'll find it's the top one.)
