well first of all check if u have placed the adsense code in the right places on your pages. For example u shouldn't make it look like ads cause this way people won't click on them, u should choose the same colours and embed some text ads into your content. Anyway just be patient cause u will have money coming from that site soon U just have to improve. I don't know your site so I can't really give u a good advice but PM me with the link so I can tell where u are doing wrong Good luck
What is your website? It is either your content not good or your ads placement/format not being studied. To improve your CTR, improve your content and optimize your ads format/placement
