Hi, I recently implemented Adsense, and I think I read somewhere that if you have FEWER ad blocks on a page, you will get both better targeted ads, and also, higher paying ads. Is that true? I'm not in a highly competitive niche, it's for my parenting advice site. I already put Adsense in in the right sideboard, I also want to figure out how to add a leaderboard within the header... and if the above is true I'd remove the ads on the right. What do you think?
