Product Category Pages Duplicate Content


Very new to CS Cart and I have searched and researched to death the issue regarding Duplicate content.

We have Pages of products, that are basically Categories populated by products.

Using rel:canonicla and rel=next rel=prev is not possible as the pages are just populated with products.

I have also read that using the robot.txt file is not the best solution.

I have looked at CS Cart Rocks addon, but I am somewhat weary in just using it and losing any of my pages rank by mistake.

Does anybody know, the correct process of elimiating duplicate content inside CS Cart?
