7 Post-migration SEO actions
Rebuild your site on the new domain. Begin creating new content as quickly as possible, paying special attention to link bait style articles that will help build up backlinks to your new domain right away. At the same time, build a new 404 page for your old site that points visitors to your name.
Really what does it matter when every backlink is for the old domain anyhow. Ever bought a domain with backlinks? Either keep both or duplicate the content and not care. You won't tranfer jack of the traffic no matter how you do it. You are starting again period.
