Changing domain and PR

Will the old links carry pr

[MHes]

Hi

I have searched the old threads but please could someone just clarify.

www.oldcompanyname.com has pr6 and hundreds of links in and bookmarks.

The company is merged and now needs a new domain name but we will keep the site on the same server. A few branding changes will take place, but content 99% the same.

Can we just make the new domain the primary domain pointing to the existing server, and keep the old domain as a secondary. Will the links to the old domain still carry pr through to the site and thus also to the new domain name?

In other words, how can I keep the pr flow from the old domain and yet use the new domain name?

Best thing would probably be to use a 301 redirect (permanent redirect).
If you need help there is a lot of threads covering this.

A 301 redirect likely would get all PR to the new site whereas simple linking to the new site would mean a loss of about 15% of the PR

i have a similar problem. An old domain with a .co.uk extension and redeveloped site on a .net domain. Uptil recently the .co.uk redirects using a 302 redirection to the .net site

the new (.net) site has a zero page rank.

having read this thread,

[webmasterworld.com...]

i realise what should have been done but have just recently changed to a 301 redirect on the old domains.

Do i need to wait for a refresh for any effect to take place (ie the Page Rank of the indexed site .co.uk, to transfer to the .net site)?

also does google recognise different page ranks for [domainname.net...] and [domainname.net?...]

Thanks

This is very similar to the case of domainename.net versus domainname.net/index.html recently discussed at [webmasterworld.com...]

My comments (for whatever they are worth) are in msg #3.

In both cases the URLs are conceptually distinct, but the general concensus is that when Google discovers that they have identical contect it aggregates the links that point to both.
