I don't get it. If it weren't possible would you be crazy? I can vouch that if it is possible, it is not a sanity plea Oh and to answer your implied question, yes it is very much possible. I get a similar CPC for my blog.
I am driving 50% USA traffic i track it with Bit.ly I average .60 cents a click with one my keywords.
You are not crazy. Hopefully. . It's possible to get that amount if you get high paying keyword or US or UK visitors to your site.
Pretty lucky for you. I remember, there are even people here shown a single click worth $28 and many others.
How much are you expecting form 17 clicks. It's possible to get just a penny or two per click so it could be much worse than what you got.
Congratz... Usually blogs about money, finance, hostings, get Higher eCPM, and yes UK,US visitors will boost your earnings.
