I notice that a lot of people link to their domains when using blackhat seo through secondary URL's, E.g. setting up mymoneysite.net and just redirecting that URL to mymoneysite.com which would be their main site. Surely if this could help your site's ranking it could also harm it and does it help/harm your sites ranking? I am looking at setting up an ecommerce site in a rather large industry and I wont make it to the top with white hat SEO, I have looked at link wheels, SENuke, BMD, XRumer and every one of them has risks of getting your domain sandboxed. Can you rank a secondary URL that you are using just to redirect to your main site to reduce the chances of getting sandboxed? Any tips/advise on this one as I would be real pissed if I get the site to the top only to get sandboxed or to spend a lot of time on it to get nowhere.
