The referer blanking method is used to hide your traffic source from CPA networks. It doesn't have anything to do with CTR.
If we blank the referee what is the number of clicks we need to maintain per lead.Say EPC and will it really work with different networks. or cpa redirection is the best option rather than blanking the referee.
It does hav some stuff to do with CTR....since it looks suspicous you want to keep it very low so it doesnt look even more suspicous
