How to Create and Manage WordPress Categories

Learning how to create and manage WordPress categories is one of the most important foundational skills for any WordPress site owner, helping you organise content logically, improve user navigation, and strengthen your site's SEO structure. Whether you are launching a blog, a business website, or an online magazine, a well-planned category system makes your content easier to find and your site easier to maintain.

What Are WordPress Categories and Why Do They Matter?

WordPress categories are a default taxonomy that allows you to group related posts together under a common label. Think of them as the broad chapters in a book — each category contains posts that share a common theme or subject. Unlike tags, which are more specific and optional, categories are hierarchical, meaning you can create parent and child categories to build a structured content architecture.

Categories matter for several key reasons:

User experience: Visitors can browse all posts within a topic they care about, keeping them on your site longer.
SEO benefits: Category archive pages can rank in search engines for broad topic keywords.
Content management: As your site grows, categories keep your editorial workflow organised.
Navigation menus: Category links are commonly added to menus and sidebars for quick access.

How to Create WordPress Categories

There are two main ways to create categories in WordPress: through the Categories management screen and directly inside the post editor. Both methods are straightforward and require no coding knowledge.

Creating Categories from the Dashboard

Log in to your WordPress admin dashboard.
In the left-hand menu, hover over Posts and click Categories.
On the left side of the screen, fill in the Name field with your category title (for example, "Travel Tips").
WordPress will auto-generate a Slug — the URL-friendly version of the name. You can edit this to be shorter or more keyword-focused.
If this category should be a subcategory, select a Parent Category from the dropdown menu.
Optionally, add a Description — some themes display this on the category archive page.
Click Add New Category to save it.

Your new category will immediately appear in the list on the right side of the screen and will be available when editing any post.

Creating Categories Inside the Post Editor

Open any existing post or create a new one by going to Posts > Add New.
In the right-hand sidebar, locate the Categories panel.
Click Add New Category.
Type the category name and optionally select a parent category.
Click Add New Category to confirm.
Check the checkbox next to your new category to assign it to the post.

Creating Categories with WP-CLI

If you prefer the command line or are managing WordPress on a server, WP-CLI offers a fast way to create categories programmatically. This is especially useful when setting up multiple categories at once or automating site builds.

# Create a new category called "Travel Tips" with a custom slug
wp term create category "Travel Tips" --slug="travel-tips" --description="Helpful advice for travellers worldwide"

# Create a child category under a parent (replace 5 with the parent category ID)
wp term create category "Budget Travel" --slug="budget-travel" --parent=5

# List all existing categories
wp term list category --fields=term_id,name,slug,parent

Using WP-CLI is ideal for developers and advanced users who manage WordPress installations via SSH or automated deployment scripts.

How to Manage and Edit WordPress Categories

Once your categories are created, you will regularly need to edit names, slugs, descriptions, or hierarchies. Managing your categories well prevents duplicate content issues and keeps your site structure clean.

Editing an Existing Category

Go to Posts > Categories in your dashboard.
Hover over the category name you want to edit — a set of action links will appear.
Click Edit to open the full edit screen.
Update the Name, Slug, Parent, or Description as needed.
Click Update to save your changes.

You can also use the Quick Edit link for fast inline editing of just the name and slug without loading a new page.

Deleting a Category

Navigate to Posts > Categories.
Hover over the category you want to remove and click Delete.
Confirm the deletion when prompted.

Important: Deleting a category does not delete the posts inside it. Instead, those posts are automatically reassigned to the default category (usually "Uncategorised"). Make sure to reassign posts manually before deleting if you want them placed in a different category.

Setting the Default Category

WordPress requires every post to have at least one category. The default category is assigned automatically if you forget to choose one. To change it:

Go to Settings > Writing.
Find the Default Post Category dropdown.
Select your preferred default category.
Click Save Changes.

How to Assign Categories to Posts

Assigning categories correctly is just as important as creating them. Every published post should belong to at least one relevant category for best results.

Assigning a Category in the Block Editor (Gutenberg)

Open a post in the block editor.
In the right-hand Post panel, scroll down to the Categories section.
Check the box next to the relevant category or categories.
Click Update or Publish to save.

Bulk Assigning Categories

Go to Posts > All Posts.
Select multiple posts using the checkboxes on the left.
Open the Bulk Actions dropdown at the top and select Edit.
Click Apply.
In the bulk edit panel, find the Categories section and select the desired category.
Click Update to apply the change to all selected posts.

Best Practices for WordPress Category Structure

A thoughtful category strategy prevents content chaos as your site grows. Follow these best practices to keep your taxonomy clean and SEO-friendly.

Keep the Number of Categories Manageable

Most sites work best with between five and fifteen top-level categories. Too many categories dilute focus and confuse visitors. If you find yourself with dozens of categories, consider consolidating related ones or demoting some to tags.

Use a Clear Parent-Child Hierarchy

When your site covers broad topics with subtopics, use parent and child categories. For example, a food blog might use Recipes as a parent category with children like Breakfast, Lunch, and Dinner. This creates clean URL structures such as yoursite.com/category/recipes/breakfast/.

Write Descriptive Category Slugs

Always review the auto-generated slug and optimise it for your target keyword. Keep slugs short, lowercase, and hyphenated. Avoid stop words like "and", "the", or "of" in slugs unless they are part of a specific keyword phrase.

Add Category Descriptions

Many SEO plugins and themes use the category description as the meta description for category archive pages. Writing a clear, keyword-rich description (100–160 characters) for each major category improves both user understanding and search engine context.

Avoid Assigning Too Many Categories to One Post

Each post should typically belong to one or two categories. Assigning a post to five or six categories signals a lack of focus and can create thin content signals on multiple archive pages. Use tags for additional specificity instead.

Advanced Category Management with PHP

For developers building custom themes or plugins, WordPress provides powerful functions for interacting with categories programmatically. The following snippet shows how to retrieve and display a list of all categories in a theme template file.

<?php
// Get all categories and display them as a linked list
$categories = get_categories( array(
    'orderby'    => 'name',
    'order'      => 'ASC',
    'hide_empty' => false,
) );

if ( ! empty( $categories ) ) {
    echo '<ul class="category-list">';
    foreach ( $categories as $category ) {
        $category_link = get_category_link( $category->term_id );
        echo '<li><a href="' . esc_url( $category_link ) . '">';
        echo esc_html( $category->name );
        echo ' (' . absint( $category->count ) . ' posts)</a></li>';
    }
    echo '</ul>';
}
?>

This code uses get_categories() to retrieve all categories, then loops through them to display each as a linked list item with a post count. The esc_url() and esc_html() functions ensure the output is properly sanitised for security.

Frequently Asked Questions

What is the difference between WordPress categories and tags?

Categories are hierarchical and intended for broad groupings of your content — think of them as sections or chapters. Tags are flat (non-hierarchical) and used for specific descriptors or keywords within a post. Categories are required (every post must have at least one), while tags are entirely optional.

Can I rename a WordPress category without breaking links?

You can safely rename the category display name without affecting URLs, because the URL is controlled by the slug, not the name. If you also change the slug, old URLs will redirect to the new ones only if you have a redirect plugin installed. Always update the slug carefully and set up a 301 redirect if you change it on a live site.

How do I remove the word "category" from WordPress category URLs?

Go to Settings > Permalinks and find the Category Base field under Optional. Type a single period or a custom word to replace the default "category" prefix, then save. For removing it entirely, a plugin like WP No Category Base handles this without requiring custom code.

How many categories should a WordPress site have?

There is no strict limit, but most sites benefit from five to fifteen clearly defined top-level categories. The right number depends on your content volume and topics. As a rule of thumb, each category should contain at least three to five posts; otherwise, consider merging it with a related category or converting it to a tag.
