It only takes a moment to rid yourself of one of the most common forms of duplicate content and link value dilution.
Do your site pages exist at www.example.com and example.com? If so then you need to create a permanent 301 redirect directing all non-www. site pages to the www. version pages of your site.
Search engines don’t want to see two versions of your content. It’s helpful to combine the inbound link equity of these versions into one page as many people don’t always target links to your www version of site pages.
