Say for example we got an eshop, with a category "car spare parts" that includes a category called "tires" which has our product in there. We have created a menu on the left where the visitor clicks on "car spare parts" then clicks on sub-category "tires" and then he visits the tires product listing.
The actual path of each product on the "tire" page, does it have to be eshop.com/car_spare_parts/tires or is it ok if the path is "eshop.com/tires".
Will the second solution cause any problems to the eshop's SEO?
