Category pages tell Google the homepage is the “real” page
A canonical tag says “this is the main version of the page”. When a category names the homepage instead, Google can drop the category from results and show the homepage — or nothing — for searches like “women’s trail running shoes”. Categories are usually a store’s best landing pages for shopping searches.
All 14 category pages in the sample, and all 28 of their paginated URLs listed in the sitemap, carry two canonical tags. The second one — which Google may treat as the deciding one — points to the homepage.
