I currently am looking into becoming an amazon affiliate and also using adwords. I'm currently looking to buy about 30 domains on different subjects, all of which have lots of books on them. For example (this is made up), lets say i bought homebuyingbookreviews.com optimize that page and then promote amazon books on there about selling your home. I was wondering if it is necessary to have each domain hosted on a seperate hosting account? Its a bad idea to host them all on one server right? Should i have a godaddy reseller account?
