My site's CMS has a manual page alias feature which is in wide use. I recently noticed that the aliased pages and the original pages are showing up in GA with separate traffic.
these two pages are serving the exact same content from the CMS, so it is in effect duplicate content which is bad for SEO. From this extremely helpful page it seems the best option is to add a canonical link to the header. Can anyone verify that as the preferred solution?
I would also like to know if this is a common problem among CMS platforms. The one we are using is called Ektron.
