Adding categories and tags to posts and pages is completely optional.
Categories allow the broad grouping of posts topics when you want to describe a post. But when you want to describe a post in more specific terms, you would have to use or add more categories, or you can start adding tags.
To add categories that pertain to your post, scroll down on the “Write Post” page and click the “Add New Category” link under the “Categories” section which will then introduce a type and drop down box, along with an “Add” button. From there, start introducing categories for your post. For example, if you were writing a post entitled “Our Thanksgiving Dinner,” you may file it under the “Dinner” category. Learn More
