I got my site to number one for my main keyword in google. I did everything myself so it was pretty easy the get to number one. I have several domains in the same category with the same keyword. Its something new that I think its going to be huge in time. So I want to start ranking all of my other domains as well to dominate the first page on google on this specific keyword. Anyone done this before? What should i think about? Can I have all the domains registered on me, in the same host? Can I link between them and have the same google analytics account?
