Why Display a Child Taxonomy on the Parent Taxonomy Archive Page?
By displaying all of your child taxonomies on the parent taxonomy archive page, you can make it less generic and more useful to your visitors.
For example, if you run a WordPress blog about books and have a taxonomy called ‘Subjects’, then you can add child taxonomies like ‘Fiction’, ‘Non-Fiction’, and more, so your readers can easily sort through your books.
When you have a lot of content, this not only makes it easier to stay organized but helps your visitors find related content faster.
