Your proxy template is so optimized for AdSense, your ad is on the left size right after the so looks-like header.
Your AdSense placement is just brilliant, congrats! 18 clicks is perfectly normal with such a layout. I have to say you're quite lucky to get clicks paying so well. That's the best paying proxy / click I've ever seen
Its ok, ive had 1 page impression, 1 click 100% CTR sometimes, doesn't happen much and its perfectly ok for things like that to happen sometimes. Its when things look too good too often that you worry. Congrats to you
