Thanks for the compiment ;) It seems I am allowed to say I was part of the trial program, and it worked out well for me. I did look around for other ad networds but I don't want to serve ads about speeding up my dialup, or mens problems. The biggest thing for me is that the ads don't ruin my site with flashing graphics, and that they are not for useless products that are quite often cons.
I think if you really wanted to you could work out the CPC by making a page that noone except you goes to, and advertise on it, and then seeing how much it costs you, and how much you get paid.
My site is a content site, and I don't really have any competition so competing products being advertisied isn't an issue. AdSense would really work best on a content site. If you have more than 200 competitors that advertise on adwords watch out, as you can only block 200 sites from advertising on your site.
Unfourtunatly, if you run the ads on more than one site you can't see which sites ( or pages ) are doing well, and which ones aren't.
Someone asked about affiliate programs for AdSense. I really don't think this will happen for 2 reasons - one is at the top of the ads they say "ads by google" with a link to [google.com...] and the other reason is that they are good enough to sell themself imho :)
I really don't think for content sites you can go for anything other than content targeted ads. Of course if anyone can find an ad system better than AdSense please tell me!
