How To Assign One WordPress Post To Multiple Categories
WordPress posts shape how content lives and breathes on a website. Categories in WordPress quietly handle much of that work behind the scenes. At some point, almost every WordPress user asks the same question: Can one post belong to more than one category? The short answer is yes. We will walk through the process of assigning one WordPress post to multiple categories in this blog. Stick with us and make an impact on your site’s organization and SEO.
Why Categories Matter More Than You Think
Categories do more than label a blog post. They group related posts and create category pages that users browse naturally. These archive pages also help search engines understand what topics your WordPress site covers.
Every post must belong to at least one category. If you forget to assign one, WordPress automatically places the post in the default category. This feature helps, but it rarely serves your site’s goals. The role of WordPress can not be understated in a fast-paced web development race. A well-planned category structure keeps your site structure logical. It also guides users browsing from one post to another without friction. When categories work together, they create a roadmap through your content instead of a maze.
When Assigning Multiple Categories Makes Sense
Assigning multiple categories works when a single post clearly fits into more than one topic. Think about a food blog. A recipe may belong under “Dinner” and also fit under “Gluten-Free.” In that case, the same post serves different audiences without stretching the topic.
What matters most is relevance. You should assign posts only to relevant categories. Adding too many categories just to cover ground leads to category redundancy. That approach weakens category pages and confuses users. Use multiple categories to group related posts naturally. Avoid using them as a shortcut for SEO.
Understanding Parent & Child Categories First
Before assigning categories, it helps to understand parent and child categories. A parent category covers a broad topic. A child category narrows that focus. For example, “Recipes” works as a parent category. “Vegan” or “Low-Carb” works as a child category beneath it. This parent-child relationship creates a clean hierarchy that supports category management. Categories also improve site navigation because users see clear paths and search engines see a logical structure. Everyone wins.
Step-by-Step Process of Assigning WordPress Posts
Here’s the broken-down process of assigning WordPress posts to multiple categories:
Step 1: Access Your WordPress Dashboard
Start in your WordPress dashboard. From the site’s dashboard, click Posts. Open a new post or edit an existing post. WordPress uses the block editor by default. You will see your content in the center and the post settings sidebar on the right.
Step 2: Locate the Categories Section
In the post settings sidebar, scroll to the Categories meta box. This area shows all existing categories on your site. If the categories section does not appear, click the gear icon at the top right. Then select Post to reveal post settings.
Step 3: Select Multiple Categories
Check the boxes next to each category name that fits the post. You can select multiple categories without limits. This simple action lets you assign a post to multiple categories at once. WordPress handles the rest automatically.
Always pause here and ask one question: Does this post truly belong in each category I selected? If the answer feels forced, remove it.
Step 4: Add a New Category When Needed
Sometimes the right category does not exist yet. In that case, click Add New Category.
Enter the category name. Choose a parent category from the dropdown menu if the new category fits under a broader topic. This step creates parent and child categories without leaving the editor. Be selective when you add categories. Creating too many categories leads to thin archive pages and poor site organization.
Step 5: Set a Primary Category for SEO
If you use SEO plugins like Rank Math, choose a primary category. This setting matters more than most people realize. The primary category tells search engines which category to assign the post to. It controls the canonical tag and helps prevent duplicate content issues.
When you assign multiple categories, SEO plugins ensure only one version of the post appears in search results. That clarity protects your site’s SEO and keeps your URLs clean.
How Categories Affect URLs & Duplicate Content
Categories can affect your permalink structure, mainly if your URLs include category paths. When you assign a post to many categories, WordPress creates only one post URL.
Problems arise when search engines see duplicate URLs pointing to the same content. SEO plugins solve this by adding a canonical tag. That tag signals the correct URL and prevents duplicate content issues.
Categories vs Tags. How To Use Each for the Right Job?
Categories and tags often get mixed up. Categories define the main topic of a post. Tags highlight specific details.
Categories form your site’s structure. Tags add context. You can use multiple tags freely, but you should stay disciplined with categories. Using tags instead of categories creates confusion.
Assigning Categories to Multiple Posts at Once
WordPress also supports bulk category changes. From the WordPress dashboard, open Posts. Select multiple posts using checkboxes.
Choose Edit from the bulk actions menu. You can assign categories, remove categories, or adjust category assignments across many posts at once. This feature saves time when restructuring older content.
Custom Taxonomies & Plugins
Some WordPress sites need more than standard categories. Custom taxonomies offer that flexibility. Developers create them using custom code or a WordPress plugin.
Custom taxonomies work well for large sites with complex content types. They also support custom templates for advanced archive pages. Use this option only when categories and tags cannot meet your needs.
Common Category Mistakes to Avoid
Many WordPress users fall into predictable traps:
- Assigning too many categories to a single post
- Creating new categories for every idea
- Ignoring the primary category setting
- Forgetting regular category cleanup
The fix always comes back to clarity. Assign categories with purpose. Maintain structure. Keep things tidy.
So, Are You Assigning Multiple Categories in WordPress?
Assigning multiple categories can improve navigation and content discovery when done correctly. It helps group posts, supports archive pages, and guides users naturally through your site. The key lies in restraint. Choose relevant categories. Respect parent and child relationships. Use SEO plugins to manage canonical tags. Keep your site’s organization clean and intentional. When you handle categories with care, your WordPress posts start doing their job and your SEO benefits without extra effort.
