Why I am not able to view the my products on the Sitemap?

If you want to see your products listed in the site map, you can add the products in one of the menus in the Navigation Tab.
  • Path: Admin > Site > Navigation
Once you go to navigation tab in you admin, you can drag and drop the product from Individual Categories and Product on the right hand side to any of the menus available on the left hand side. Once you add the products, save the changes.
