Topic says all. So i want to know can i use a site to apply for adsense which already has adsense on it but never used to apply for adsense?
Yes, That is OK! Coz, Adsense is placed in many situation other than the owner Directly put his ads in a Website. It can be a revenue sharing, or AdSlot sale or anything!! So there is no problem in applying with a website which has Adsense, As Far As I Know!! ~ExP~
This questions could be answered better by asking Google themself. I can see it now: "..but google, the DP people said it was ok."
