So don't jump all over me because I'm using YPN lol. What do you think I could do to get more clicks? I've tried a lot of different things but I can't seem to get higher then 0.1% CTR. The site is http://www.completemyspace.com
it's not uncommon for ypn to get really low CTRs. you may want to try adsense and see if your overall revenue is better. as far as specific tips, for starters, you may want to try matching the font used by ypn with the site's font and the site's link text font/weight. you could also try the "images trick." another note is that more ad units is not always best. try going down to two or one and see how that impacts things.
I think the picture thing is no longer allowed by YPN. I removed half the ads on the page. I will try to match the font and stuff right now.
