If you have a website at xxx.hostedblog.com and you buy a domain name for the blog and use a 301 redirect, does it have any impact on SEO? Specifically, if some sites link to xxx.hostedblog.com and others link to the domain name itself (which redirects to the blog), will this affect the PR in any way?
Hi Redirect 301 is good for SEO It represents permanent redirection form old url to new url. if u have implemented redirection 301 in your site that is good nad that which links to your older site automatically redirects to new blog domain.
