When you add the description to your WordPress tag, you should go to the **’Tags’** section under **’Posts’**, and click the tag name to edit. You will find a box labeled ‘ **Description’** and that’s where you insert your chosen description. If the text editor doesn’t auto-complete the field for your tags, you may need to add this description via a plugin that supports tag descriptions.
