Merging 2 sites into 1 with 301 redirect

thanks for the suggestions

These are some interesting questions. Will be watching the responses to this as well.

By the way this is what SEO Moz has to say about 301 redirects and passing link juice:
"
301 Moved Permanently
A 301 redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page. ... In most instances, the 301 redirect is the best method for implementing redirects on a website."
So I suppose the answer to think link juice part is, all of it.

risky business you can easily fuck up your high quality backlink site this way. Good luck

Darko666 - Agreed, but top 5 sites are ranking with spammed backlinks only.

it also depends on how you are redirecting are you redirecting via a subdomain?
