Question : Forwarding Multiple Domains, How to benefit SEO?

I am developing a site on a dev server. Just purchased some domains, but not yet deployed. The staging site is http://touchingheartsministries.monkcms.net/ and the live site will eventually be deployed on www.growinggreatmarriages.com

I also own and intend to forward the following domains to the aforementioned domain:
www.growinggreatmarriages.org
www.growinggreatmarriages.net
touchingheartsministries.com
richardandkathyharrison.com

What is the best way to set these up for optimal SEO? Does domain forwarding do anything for SEO, e.g., will growinggreatmarriages.com benefit at all from a google search of "richard and kathy harrison"  if richardandkathyharrison is set to forward to growinggreatmarriages.com? Anything else I should be doing?

Thanks!

Answer : Forwarding Multiple Domains, How to benefit SEO?

You will need to make sure that the homepage at   www.growinggreatmarriages.com is well optimised tho so that it will rank for "richard and kathy harrison"

With regard to the other domains Google will follow the 301 redirects and see these changes. Over time it will de index the older domains and all value would have been passed to the primary domain.
