I have placed one link unit, one leaderboard and one square ad unit on my site. After looking at heatmaps and what Google recommended, I placed them all at the top left area of the site. Main Site: http://www.newbtopro.com Random Article: http://www.newbtopro.com/guide/html_tutorial (So you can see all ad placements). Can you give me some feedback on better ways to place these ads? Thanks
