With the PublishPress Checklists plugin, you can require a maximum and minimum number of categories for your WordPress posts.
If the correct number of categories aren't added, you can choose to show a warning, or prevent the post from being published.
Having the correct number of categories is important for your site's SEO. This guide shows how to choose the number of categories.
By default, Categories are only available on WordPress Posts. However, you can add Categories to other post types and so you will be able to use the tutorial for those post types too.
