Confused about "cpc"

Have you taken “cpc” ops at social spark? I tried and posted it in my other blogs but I’m so confused and wondering why there wasn’t any clicks showing in my taken ops section which is really impossible. Not even one clicks? Really! I don’t know how they count valid clicks and earn from those clicks. My friend one time mentioned me that she visited the link and even places an order on that site but when I checked my taken ops dashboard to see if there were clicks and to my surprise I found nothing. Hhhhmmmm? It made me think now. The link has been in my other website for months now but there aren’t showing any clicks. Would you believe that? I stop it though because it’s not fair at all.
