Obviously some sites are better at generating money than others, but what kinds of sites should just forget adsense altogther? Are there any or is it just a matter of tweaking?
I would say that your site www.Cudos2U.com would NOT be a good candidate for Adsense because you are trying to sell product thru your site. 99% of Adsense ads that would appear on your site would only offer your potential customers someplace else to shop.
If you want to generate additional income you may look into affiliates.
