Keeping Pank Rank After Transfer

I want to move my site to another domain, what is the best way to make the switch without sacrificing all my hard earned pank rank

 

301 Redirects on each page is the main recommendation - but you will lose page rank and SERP rankings as you will lose your old backlinks.

 

Each page ??

What if I have a wordpress blog with over 150 posts

 

You can either use a one line .htacess redirect to redirect everything from the old domain to the new domain with a 301 redirect (as long as the directory structure stays the same, everything after the domain) or you can use modrewrite if there are more advanced changes.

 

301 redirect is the best choice but you may lose your pr's.

 

You could always keep your old and new domain names. Park one to the other then just promote the new one. You still should be able to retain the old domain and thus the PR and then you can take your time to build the PR for the new domain. Once the new domain gets the desired PR, you can give up the old domain name.
