Here's the situation - a client of mine has recently changed their company name and have changed their web address. They want to completely cut all ties with their old brand, so they have told me that their old website absolutely cannot redirect to the new one.
The old domain has a PR of 4, so it would be nice to carry some of that authority over to the new domain.
The new domain has just been registered so I'm really starting over from scratch in terms of SEO. I can't use 301 redirects and I can't link to the new site from the old one. Is there anything I can do?
