Hi
I have a terrible niche for Adsense, but I'm not doing too lousy. I have a very good CTR and lots of traffic. So even a low paying niche can succeed.
I encourage you to experiment. Create a log of your activity and start by testing different placement locations, different sizes, etc. I found that the standard blue link did not work that great for me. But when I changed the link color to a very, very brilliant blue (forget the number), the ads blended into my site while the links really popped out.
This resulted in an increase that has been lasting for going on 6-7 mos now.
So test and keep a log. Find what works for you. Traffic is also a factor, keep in mind. But you can still optimize while you build traffic.
