I recently signed up for an account with SEOMOZ.org to start getting into doing a better job at SEO for my site. SEOMOZ is giving me duplicate page title and content warnings for every blog posting that I have. One example is the following URLS:
http://www.productsforautism.com/blog/10/contactus and http://www.productsforautism.com/blog/10/early-childhood-evaluation. They both of the same title. I don't know why the first one even exists, but you can browse to it. I am also getting the same problem with my category pages: http://www.productsforautism.com/c/21/contactus and http://www.productsforautism.com/c/21/language-arts. Anyone have any ideas why the contactus page exists in these cases?
