I have a (brand new) client whose brand name site is penalized--he wants to hang onto it. I want to create a new site and just let the old one sit as it is, but he wants to connect the original to the new site somehow. Obviously, I'm not keen on doing a 301 redirect from the penalized site to the brand new site we're creating (same brand name, different TLD) because I don't want it to pass along the penalty. I'm not sure how we could keep the penalized site in the mix other than to disavow links, start building new content, and give it a few months to recover. Is there some subdomain trick that I'm overlooking that would allow us to circumvent this problem? What is the best option here?
