Welcome to the Q&A Forum

I have a site with multiple regions the main page after a region is selected is login.php but the regions are defined by ?rid=11 , 12, etc. These are being picked up as duplicate content but they are all different regions. As i hired external php coders to develop most of the site I am scared to start meddling with any of the raw code and would like some advise on how to not show these as duplicate content. should i use noindex nofollow or connical? if Connical how do i set it up on the main login.php page? p.s. i am an extreme nube to seo
