This question already has an answer here:
Lets say I have a site at "myrandomdomain.com". I want to target a keyword "my keyword" and so I buy "mykeyword.com". Can I still have the keyword benefits of having mykeyword.com when it just forwards to myrandomdomain.com? The domain would not be masked. My guess would have been no but SEO Moz seems a bit unclear about it:
A 301 redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page.
I'd just like to make sure before I switch my site over. If it would have the same effect to forward it I'll just do that.
