I wouldn't expect this for long. Unless you have an incredibly new, untapped niche that is high paying. Even finance/credit card blogs do not bring in this CPC.
It's normal yes and happens sometimes! Yesterday I had 5 clicks worht 3 Euros each!!!That's about $4.5 per click. So I earned more than $20 within a few minutes. I couldn't belive my eyes...
My average click is less than $0,2 but that day was a very good one with average clicks going through the roof. Don't know exactly what happened, but next day the CPC went down to normal...
