Point Multiple Domain Names to 1 website?

[willardnesss]

I have a website that I would like to have multiple domain names point
to.

example:

Current domain name: www. my site.com

New domain names to add: www. my special site.com, www.my super
site.com

These new domain names are my company's full name spelled out and a
few other versions that would make sense for my customers to type in
as a URL hwhen searching for my website.

I am currently within the top ten on all of my key words in Google & Yahoo, so
I don't want to risk screwing up my Google ranking.

What is the best way to add the new domain names to point to my site
without having Google think I am trying to spam them?

Thanks!

You need to set them up as 301 redirects to the domain name that is currently ranked. Google and other spiders will see this as a moved perminently and just throw it away without indexing it. If you make it a 302 you could run into problems with duplicate content so make sure it is a 301.
