It is fine because my friend and his brother are having different account in the same postal address.
That is not a propblem to open the accounts in the same house hold. She is using different website and you are using different website. But for the same website dont open different adsense accounts, that is against adsense laws.
I guess it depends on how much money you are making and how willing you are to part with it. Google says to not use the same contact information. I know you can have the same name on the accounts but does this mean address as well? Who knows. It's better to be safe than sorry. Just use a separate address like a PO Box of friends house.
It absolutely fine... as long as you and not breaking their TOS ... I have an adsense account from Dec 2004 ... my better half from June 2007 ... No problem.... Create good site, good and unique content .. learn SEO... promote your site without the obvious spam and you are good to go... Ani
I dont think so that it will be a prob if 2 people use same postal address and access from same IP. also for over confirmation you can contact google support team.
