Due to this, the majority of the current website is duplicated through just companyname.com/whatevercategory and companyname.com/companyname testing site/whatevercategory.
So I thought a way to remedy this would be to unpublish those duplicated pages and then possibly uninstall that joomla instance. However, if I unpublish or make any changes to a page under the testing site then it is mirrored on the page on the regular site - so I am worried if I uninstall that instance of Joomla it will take down the entire site - so won't be trying that.
I figure I can just add a line to robot.txt that says Disallow /companyname testing site/ and de-index those duplicated pages that way
Have any of you ever seen this or know of a better way to fix this?
Also I know there is a whole debate here on duplicate content being a myth or real - I really don't want to get into the debate - I would rather play it safe and remove all this since the entire page - graphics and all are entirely duplicated.
