I get many, mannyy $1 FF referral conversions every day.. I get several $2 GooglePack conversions every day my site is a particular niche in the tech-ish world.. i know you were referring Adsense for Content clicks in your post, but since i am the Referral King , i thought I would point out that referrals can be a great way to regularly get $1 per pop..
I have had more than a few that paid me over $1 and $2 a click. It all depends on what site is about. I also have had more than a few for 1/2 cent until i blocked the sites from showing adsd on my sites.
It depends on different niches topic that you choose. I had some medical websites, which are getting me on average of /click 0.3$-2$ at times. And more common topics dont get you much.
From one of my sites, almost ALL my clicks are above 1.00. Once I got a 2.00 click. Maybe I got more, but you cannot always catch those when you have more than 1 click on a channel. Ummm, that site gets all those $1.00 clicks, but I also have a site (another niche) which sucks and gets like 0.05c clicks. I am planning to close the latter one. No need to deal with that kinda crappy ecpm.
