Let's say I have this adsense tag for and hosted on website 1 and on website 2, I have an iframe to that adsense ad on website 1. How do I mask/change the source of the click (i.e., from website 2) such Google does not see where the clicks are coming from, or thinks the clicks are coming from visitors on website 1 instead of website 2?

I am using adsense purely for analogy purposes.
