Just curious for those with more knowledge than myself. I see that google allows you to place 3 ads per page. Right now I currently run 3 leaderboard ads. Now all 3 ads are the same exact ad code but just in 3 different areas of my homepage. Should I be doing this or would it benefit me more by adding the 3 separate leaderboards but with each one being a different ad code? Just wondering that would make a difference in revenue or if I wouldnt see any changes.
