Hi. I have a PR5 domain that gets 20000 hits daily and I want to change the domain name. What's the best way to do this without losing all my traffic and to make sure my pagerank and link juice gets back up again afterwards?
301 each and every individual page to each of the new urls, you'll still loose some rankings and probably PR but in some months you should make it back. Make sure you register both domains in the same Webmaster Account before you start the redirection, it should make things a little smoother.
