How to use your sub-domains
I wrote yesterday about how to choose your domain name. So you already have the perfect .com domain containing your primary keyword and you decide to go out and purchase the .net, .org, etc. What do you do now?
One thing you can do is a 301 redirect which will send any new sub-domain visitors to your primary web page. A 301 redirect is fairly simple to implement when compared with other methods and as long as the user is being redirected to relevant content, they probably won't even notice the difference.
