and I want to change domain. I can place redirect, but PR and back will drop? What is the best way to change domain?
if you use 301 redirection from your old domain to the new domain then the PR will be automatically updated to the new domain on a next PR update. However, you may lose back links due to the domain name change.
If you use a 301 redirect, and the PR is updated on next Google update, will it show up as a "Faked Page Rank" on new domain?
