Daily SEO Tip – To WWW or not to WWW
August 22nd, 2008 Posted in Uncategorized
That is the canonicalization question! When you talk about your site being listed with and without the www prefix, that’s called the canonicalization of your domain. Basically, it just refers to your preferred URL for a site, whether that’s with the www prefix or without.
Search engines can sometimes index both versions of your domain, creating duplicate content headaches for you and also link popularity dilution. For those reasons, I strongly recommend you decide which URL version you are happiest with and implement 301 permanent redirects at the server end to ensure your preferred version is served no matter which version is typed in.
Your web administrator or SEO Consultant can assist you in setting up a 301 redirect.
