Multiple Domains for One Website and SEO

[Taryn_S]

I have purchased multiple domains for mydomain, such as mydomain.com, mydomain.website, and mydomain.info. I am setting up one website which will contain all of the content and choosing one domain to be "the" domain. The only reason I am buying additional domains is to be able to keep the name to myself.

I researched using rewrite rules and then 301 redirects, but I'm seeing alot of problems with duplicate content and page rank associated with multiple domains. Since I don't want the content to be associated with the additional domains, the solution I've finally come up with is to change the destination of the additional domains to an empty subdirectory and cause a 403 error due to the permissions assigned to the subdirectory. If the additional domains are 'forbidden", then I can concentrate on one domain and hopefully have no issues with seo, duplicate content, and page rank.

My questions are, is there a better way to "hide" the additional domains? Will this work for seo?

I would appreciate any help, thoughts, ideas, thanks.

as you are not promoting the other domains, there is no reason to redirect them. i would either not point them at any website at all.
or just set up a holding page for each one, with a message on it saying something like:
welcome to 'example' our website is found at example.com with a link to example.com (many domain name sellers will give you a free webpage with your domain name)

@topr8, thanks for replying. I am buying all of the additional domains from my web host, and by default, all domains point to /root. I think I would prefer to have the additional domains "not point to any website at all". For the domain destinations, the only choices I have is to use /root or /subdirectory. Since I want "the" domain to point to /root, I pointed all of the other domains to an empty subdirectory.
