I just had chat with PC support and they told me i have 10 free signups (and they say should be 3-5 times better) this month from 1000 clicks so i will stop banner and broker promotion, he told me to focus on more targeted traffic. Will see what can i do with PPC and SEO pages because this looks like mission immposible with traffic i send now 
 
So to make small traffic "bill" :
Banner traffic:
428clicks  	113,846imp  0.38%ctr  $56.81cost
Broker:
400 hits 2$cost
Other traffic is from iframe/banner ads on amateur and asain blogs of mine. 
 
ps - will run ~40$ on that banner spot but for awe to see how much free signups i can gain there.
