Hello, Well basically I was, and still am, pretty new to adsense. I made a tech-blog, wrote few articles, applied for adsense and got approved. Firstly the CPC was arround 0.6-0.7$. After a while I put really unattractive ads (like image ads in middle/bottom of the post) and didn't analyze my adsense account for maybe two months. The CTR and CPC dropped drastically, from 0.7$ to something like 0.02$. How to get the old CPC back? I deleted those image ads, returned old text ad but still I got something like 0.02$. If you want to check the site you can send me a PM. Kind regards
