I am having an e-commerce site and current URL structure is like this:
www.example.com/category1[Category landing page]
www.example.com/category1/sub-category[sub-category listing page]
www.example.com/category1/sub-category/product-name[Product Details page]
I am finding it difficult to identify from the URLs whether the URL is category landing page or a listing page or a product details page (primarily in Google Analytics). To solve this problem, I am thinking of adding qualifiers in the URL as follows:
www.example.com/category1/cat-land[Category landing page]
www.example.com/category1/sub-category/cat-list[sub-category listing page]
www.example.com/category1/sub-category/product-name/prod-details[Product Details page]
Original URLs would be redirected to new URLs using 301 permanent redirect.
Would this have any negative effect on existing SEO and Google ranking?
