I've come across what appears to be very poor behavior in regards to SEO with the way newer versions of DNN are handling non-existent child pages.
As example: http://domain.com/about
Navigating to that domain would result in seeing the content for the about.aspx page.
However, it appears that navigating to any of the following will also result in seeing the content for the about.aspx page, but listed at different urls... Note: None of these are actual pages in DNN.
Correct me if I'm wrong, but won't google see this as duplicate content? It will see each one of those pages as having the exact same content.
I realize that the likelihood of the bogus url's being indexed is slim to none, but what is to stop someone from creating url's on his or her website to point to http://domain.com/about/derogatory-terms-about-this-company/?
I would think this could have messy seo ramifications...
