Category pages win on links, not just products.
Compare your key category page against the top three results in Ahrefs, looking at referring domains to both the page and the domain. Retailers with excellent ranges regularly lose to weaker catalogs backed by stronger link profiles. Editors rarely link to a category page directly, so campaigns earn links to the domain and to linkable assets, then push authority to categories through navigation and internal links. When a story genuinely features a category, like a price index built from it, direct links happen too.
