Transfering rankings and PR ?

Hello ! (I hope this is right category for my thread)

Can somebody give me an advice on following situation?

We have SEO optimized and well-ranked site. We want to separate one part of this site as new one.
It will have its own domain name, structure and pages.

Do you know any ways how to transfer rankings and PR? (I mean how to save positions and PR for the same content pages after separating domain)
Or we should start SEO again from the beginning?

Any answers and ideas will be greatly appreciated...

Thank you.

 

I think it's a great idea- I've done this many times.

I don't think there is any way to transfer rankings without breaking some rules and risking your long-term rankings.

I recommend interlinking the sites (avoid dup' content) and your new site should gain quickly.

 

You can use mod_rewrite to produce a permanently moved response (302 I believe) that will help you out. The PR won't transfer immediately, but your rankings shouldn't dramatically suffer - and all the users trying to get to a page on your main site will automatically be forwarded to the new one.

I haven't created a whole new site like this, but I have moved pages successfully within a site.

 

301 is a permanant redirct, the 302 temp can get you in trouble with google.
