Advice and answers from the SupaDupa Team

No, you will not increase your Google rankings by using multiple domain names. Your SupaDupa boutique has one Primary domain name, that any additional domains you own can redirect to, but it is the primary domain that Google will consider in its ranking factors.

This is done so that you are not penalized for having multiple identical sites and so that Google does not get "confused" about which one is the Primary or authoritative site.
