Magento - Assign product to subcategory after indicization of parent

Question

I have decided to create some subcategories to better separate the product, untill now(2 years) I only had the category with the brand name, but now I would like to add some subcategories:

• Brand
  • Face
  • Body

and Google shows this as snippet:

www.example.com › Home › Area › Brand

My question is: how should I act to avoid google errors like duplicated content or similar? Should I remove all the products associated to the category Brand, link them to the subcategories and anchor to the parent? or should I leave the actual configugration and add noindex to the subcategory?

Answer 1

Solution: add the canonical URL to the product page and point it to the "root" magento/product.

Not sure if necessary, but probably yes for the sitemap: remove all the asssociated product from the parent category and add them to the sub ones.
