Welcome to the Q&A Forum

Thanks for the quick replies (and I agree entirely).  I was curious because I came across the URL and you just do not see a lot of sites doing that.  The Grainger brand appears to do quite well in Google, but its probably more a result of the big brand affinity than having solid optimization in place.

Wondering if there is any value for e-comm sites to feature a reverse breadcrumb like structure in the URL?  For example: Example: https://www.grainger.com/category/anchor-bolts/anchors/fasteners/ecatalog/N-8j5?ssf=3&ssf=3 where we have a reverse categorization happening? with /level2-sub-cat/level1-sub-cat/category in the reverse order as to the actual location on the site.

Category:  Fasteners
Sub-Cat (level 1): Anchors
Sub-Cat (level 2): Anchor Bolts
