Magento URL Question

[PerchDigital]

Calling all Magento Kings out there!

I'm working on a client' site - powered by magento. I'm looking to rewrite a lot of the URLs. I know there is the URL rewrite tool, but I think what I need to do may go beyond this.

Typical example would be:

Old URL - http://www.xxxxxxxx.co.uk/fabric/product/product-black-screen-print-and-silver-fabric.html

New URL - http://www.xxxxxx.co.uk/fabric/product/silver

I know that magento's URLs seem to be created through categories so wanted to double check with someone the best way to do this.

Also, I've heard that 301 redirects of non www to www in the .htaccess has a knock on effect on discounts?

All comments greatly appreciated.

Did you have the time to reads Yoast SEO guide on Magento ? he have a nice SEO extension. where all products will have www.example.com/prpduct.html (good to resolve DC)

Hi Wissam

Yes, I read through it and a few others, but wanted to get clarification on some specifics not covered all that in depth in the guide.
