Hello! I'm from Romania. I have a google adsense account performing great. My traffic exploded those days and i want to change the host. The one i use now is a romanian one, but i want to move to mediatemple, which is in USA. I heard or red something about Adsense policy about Taxes and stuff reguarding USA hosting? Please help Thank you!
Dont worry about it, that stuff is regarding the tax forms. Just ignore it, nothing will happen. Go ahead and switch your host.
You've built links to the old URL - so a new URL means starting over from scratch in the search engines. Not that nothing can be done to minimize the damage - but you should not change URL's, if you can avoid it. Unless your current profits are not on your own domain name. in that case, buy a domain name as soon as possible - for the same reasons: you want to build a reputation and links on your own domain name, not someone elses).
