URL Redirect Question

Hello All,

I am wanting to automatically forward to a domain out of a long tail keyword domain. Let me Explain:

Let's say that Domain A is a Longtail Keyword Domain, and Domain B is a poorly ranked money domain, like a CAP offer domain.

Let's say I put some keyword content on Domain A and get it ranked for the keyword well, but I want anyone who clicks on it to go to domain B automatically.

If I do a 301 redirect. Google sees the poorly ranked domain. I want Google to see the Keyword rich domain at and the people to see the Money site.

How can I do this?

Thanks in advance.


Seb
