I have a blog on Blogspot (owned by Google). I would like to host it under my own domain. So I would consider 3 options:
Create a Domain redirect to Blogspot
Re-direct the existing blogspot URL to the new domain (don't know whether Blogspot allows this)
Simply link from Blogspot to my new Domain (e.g. "This is the new version of my blog")
Which one would be best for keeping my existing Google rank? In particular, I am curious about (1) - would Google assign to my new Domain the rank of my existing Blogspot URL if the former redirects to the latter?
