I've been through the forums and searched around for an answer but everything I have tried so far. It seems to be a common problem and others haven't yet found a good, definitive answer.

I am using SEO Moz - if you haven't heard of it, it's great for SEO and gaining insight into where you can make improvements on your sites. Every Concrete5 site I build and run SEO Moz on it, it comes back with lots of crawl errors saying duplicate content. Does anyone know how to fix this? I have tried htaccess etc but not luck.

Any help or things to try would be greatly appreciated.
