I have a site with a dot com domain name. I want to start a wordpress blog which will be on my server at hostgator to promote the site. Is it ok for seo purposes to use the same domain name for the blog, with a .net or .org which I already own, or should I get a completely different domain name for this blog.
I know about free blogs, and use them, but I want to create one on my own server, which I feel is easier to deal with. Any info would be appreciated.
