I decided to switch over to WordPress recently and I've been able to import all of my former Blogger blog posts and comments without any difficulty, but haven't yet shut down the original blog nor redirected traffic because I have no clue how to deal with my Google page ranking. I understand it's a bad idea to have the same content posted on two sites, and that I could be penalized for this, but this is only a temporary situation until I figure out if there's any way I can preserve my page ranking which took me 5 years to build up (assuming I haven't already been penalized). I should add that I now use the same blog name, but under my own domain. I'm sure others have been faced with the same issue.
Any helpful suggestions on how I can retain that page ranking now that I'm on WP or do I have no choice but to start from scratch?
The blog I need help with is fromsmilerwithlove.com.
