The structure of your URLs—organizing URLs into domains, subfolders, and parameters—makes your website more readable for users and search engines. URLs indicate the site’s sections and subsections. Imagine a site that uses numbered URLs instead: “example.com/12,” “example.com/13,” “example.com/14,” and so on. This is much harder to understand than a website with subfolders describing their purpose: “example.com/products/,” “example.com/products/bath-mat,” “example.com/about/,” “example.com/about/team.”
