why will it be against TOS ? there might be two people running the site , so two accounts there, i dont think it violated TOS unless someone puts an official word from google here.
so does this mean i can have one accounts adsense on one page and another accounts adsense on a different page in the same website??
It's allowed due to which the same with sharing mod. but both of account owner can't be the same guy.
Hope that answers your question : Long story short : No more than 2 publisher_IDs on the same page You can use 2 IDs but not both at the same page load
