All questions about post types/taxonomies and permalinks seem to be about altering and changing the permalink. I wonder how to hide a post type or a taxonomy completely from search engines, prevent creating permalinks, etc.
Say I use a page and in the specific page template I add a couple of content boxes. These content boxes are custom post types.
Now I want visitors/search engines to visit my pages with
www.example.com/page-two but I never want anybody use/see
www.example.com/content-boxes/my-about-box. How can I do that, if every custom post type/taxonomy seems to automatically generate links and be accessible.
