问题
Opencart produces different links for a product like:
website.com/product_name
website.com/category/product_name
website.com/category/subcategory/product_name
website.com/brand/product_name
etc.
It is based on the listing page which you reach to product. My question is that, using different links for a product/content is beneficial or harmful for seo? I will make it one link if it is harmful or unnecessary.

Personally I find it bad for SEO. From what Google says, it really doesn't matter too much since it just ignores duplicate content not penalise as some suggest - plus each product page has the canonical URL's which again Google will make use of. However, if you are looking for something to make your URL's more consistent, I have an extension (commercial) which does make them all uniform across the site (and also makes the pages breadcrumbs the same too)
