301 Redirects and SEO

Whenever you change the URL of your pages, or register additional domain names that point to your main site (like when you set up mysite.net and mysite.org to point to mysite.com), you will have to implement some sort of redirection. 301 redirects are the only kind of redirection endorsed by the search engines. I have just written an article on 301 redirects that addresses when to use them, why they are important for search engines and how to implement a 301 redirect.
