I have very poor price/clicks on one site of mine.. between 0.05-0.08$/click... i'm thinking to change the ad formats.. any chance to improve the pice/click in this way or what else can i do?
The price would purely be based on your traffic & niche .. either you have low pating traffic, low paying niche or even both. One ot my sites has a decent niche, but bad traffic about (only 25%US/UK) .. and I am actually around the mark you are at. Work on the traffic and I am sure things will improve.
