If you use child categories in WordPress, you’ll probably notice that by default, WordPress, displays posts associated to a child category in its parent category, even if it’s not associated to that category. This can be a problem as far as search engines are concerned because it creates an issue of duplicate content. There are a few ways which can be used to tackle this problem but most of these methods require editing of your WP theme which can be a complex process and so this is where the Post Category Only Plugin comes into play. All you have to do is download and activate this plugin and voila! The posts will only appear, in categories they are directly assigned to.
Here, is a better explanation. Suppose you have a category named “WordPress” and “WordPress” in turn has a child category named “Themes”. If you create a post and publish it under the “Themes” category, the post will be displayed under both /category/wordpress/ and /category/wordpress/themes/ instead of just being displayed under /category/wordpress/themes/. Once you install and active the Post Category Only plugin, the post will no longer be displayed under /category/wordpress/ until and unless you explicitly assign WordPress as one of its categories.
