I want to know about followings: 1- Can I use the same Google Adsense code for various pages or one code is just for one page & i have to gain new adsense code for other page??? 2- I want to use a script in my new website but it contains the adsense code of another publisher. Can I use it on my site or it is against the TOS of Google to use 2 advertisers adsense code on same site???? Waiting for reply.
yes you can use different adsense code but its recommended not to messs up the things as it can lead both accounts in risk you can look this link https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=115988]
Adsense has a option to allow particular sites where your ads will be displayed. If The publisher of other code has restricted other websites, then using those ads on your site will be of no use. And you never can know his/her settings. You can create individual ads for each individual pages by creating channels and that is how you can track performance of every ad on every page.
