Mines around $8 but it varies considerably from site to site and niche to niche. Vote in the poll and lets see where we stand. P.S - I messed up - the $6-$10 should be $8 - $10. I can't go back and fix it so if a mod could correct it that would be great P.P.S - Someone commented on the $15-$20 in my sig - that refers to all income sources for a site. You should be using other income sources as well as Adsense. My Adsense income makes up less than 15% of my overall income.
You should probably take advice from your own sig Jason, because apparently your eCPM sucks . (not that mine doesn't suck by those standards)
Thats combined for all income sources. Not just for adsense. You should never really just be using adsense on its own.
