my question is How to add more then one sites for displaying Ads. i have 50+ good PR indexed Pages where i have full Admin Access. can i just make ads and copy /past code to my pages? this way is good or not? or how can i add sites at adsense ? waiting for your Response... thanks in advance rajeev
You can just copy and paste the code onto separate pages for the same site. If you want to use channels to track which ad units are getting clicked on which pages, then you can create multiple ads and paste different code on each page.
you can generate one ad code and put the code on all sites if you want. however, there will be no way to track how many impressions and clicks you are getting form which site. if you want to track the earnings per site, then you will need to add URL channel where you will setup one ad code per domain. or you can even add channel to your ads so that you can track performance based on each ad unit.
