I have been reading this forum for about a week or two now, and I have become very interested in starting a website to test and learn SEO from. My question is, I have seen many things that you do not want to link multiple domains to the same account (hosting, adsense, etc). Is this true? You shouldnt have more than one domain on your hosting plan, adsense account, or anything else? It seems like that would cost a lot of money to maintain.
