Yes my GF started a blog we put ads from my adsense account on her page but she wants to see how many clicks she is getting and see if she makes any money So we changed the ads so they would be from HER account ? Is this fine? or should i change them back to the original ads from my account?
Yes it's fine putting the ads generated from your account. Channels work, but even if you don't use them G will track uniques domains seperatly.
It's OK. The code generated on the blog can be generated from your account and viceversa. Either code is just fine.
Just be sure you don't have ads from two different adsense accounts displaying on the same page at the same time. That is a violation.
