Say we have two identical websites, one with backlinks and traffic on the homepage which has categories x y z and one with a category which includes the x y z subcategories. The navigation sidebar shows the subcategories under the category. Would the first case get more views? A SEO setup that I'm working on requires me to do something like the second case and I'm not entirely sure whether it'll work or not.
I wonder whether or not google would deem subcategories somehow less important and related to their respective categories as compared to homepage in relation to categories, therefore lowering SERP results of these subcategories.
