Does anyone knows if you can put adsence on upgrated sites from let's say ,tripod ,geocities ech? or is not permited? I mean upgrade is when you pay the host company and your site is clear of the host companie's adds.An answer to that it will be very welcome.Thanks in advance.
LOL, I don't think this is the right thread for asking a question like that. However it does go a long way towards explaining why questions like these are constantly being asked.
There is a relevant section in the Terms and Conditions (section 13), but in typical Google fashion it's clear as mud. In the past, Google has interpreted it to mean that you have to own the actual domain that you're putting the ad code on (i.e. tripod.com). I'm not aware this has changed.
