Please review my site www.jewelry-exporters.com for adsense placement. I will be obliged to hear your suggestions for its improvement.I have placed the ad's some 3 days before and has yet to see good results...
For the table on the right side, you can see there's lots of white gaps/areas in that table, I would set the table to the EXACT same background color as your adsense ad. Remove the ad on the bottom of the site and place a smaller one somewhere inside the content area.
Are you talking about the product groups which have subgroups inside ? I also feel that there is an empty space between the two boxes . Placing an ad inside the content is a good suggestion , thanks!.Let me wait for more suggestions before I implement these changes
