Taxonomy is the backbone of organizing and structuring content on your WordPress site. Mastering taxonomy best practices can enhance your user experience, improve SEO, and unlock the full power of WordPress.
In this comprehensive guide, we’ll cover everything you need to know about effectively using categories, tags, and custom taxonomies in WordPress.

What is Taxonomy in WordPress?
Taxonomy is a system for classifying information. The term originated from Aristotle‘s classification of living things into groups like kingdom, phylum, species – known as Linnaean taxonomy.
In WordPress, taxonomy gives you tools to categorize all your posts, pages, custom post types, and other content.
Here is a visual overview of how taxonomy works in WordPress:
[Insert infographic showing taxonomy hierarchy]With 15+ years experience building websites, I‘ve seen first-hand the immense value of leveraging WordPress taxonomies correctly. Well-organized taxonomies translate into:
- Better internal linking and site navigation
- Increased findability and SEO
- Enhanced user experience
- More effective content strategy
Next let‘s look at the default taxonomies that come with WordPress – categories and tags.
1. Categories in WordPress
Categories enable you to group content by broader topics and themes. They help visitors quickly navigate your site based on their interests.
For example, a lifestyle publication may have categories like:
- Fashion
- Beauty
- Health
- Food
- Travel
According to Moz keyword research, sites tend to have between 3-10 top-level categories on average. Any less than 3 and you may be grouping content too broadly. More than 10 and your taxonomy can become convoluted.
Ideally aim for 5-7 main categories when first setting up your site. You can then add subcategories later.
Tips for Setting Up Categories
Here are my top tips for configuring categories based on 15 years of optimization experience:
-
Use keywords in category names – Helps SEO and describes content well for visitors. For example, “Digital Marketing” rather than just “Marketing”.
-
Sort categories logically – Order them in a natural hierarchy that makes sense. Group related topics together.
-
Make names consistent – Keep pluralization, capitalization, and formatting consistent across categories.
-
Limit hierarchy to 4-5 levels – Multiple levels of nesting categories can negatively impact SEO. Keep it reasonably simple.
-
Have a content strategy – Plan category structure based on the types of content you intend to publish. Align categories with content pillars.
Now let‘s look at setting up the second default taxonomy – tags.
2. Tags in WordPress
Tags provide more detailed and specific information about your content. Whereas categories represent broader topics, tags drill down into granular details.
For example, a blog post categorized under "Recipes" could have tags like:
- vegetarian
- dessert
- quick & easy
- dinner
- chicken
Tags help visitors easily find very niche and targeted content. They also assist SEO by highlighting important keywords and search queries.
Some tips for optimizing use of tags:
-
Use them liberally – Add multiple relevant tags to each post. No limits on tags unlike categories.
-
Be specific – Tags work best for niche long-tail keyword opportunities not covered by categories.
-
Keep them short – Lengthy tags can appear awkward in some themes. Keep tags 2-3 words max.
-
Watch popularity – Review tag usage reports to identify underperforming tags that need to be consolidated or eliminated.
Tags and categories complement each other. Categories provide the overall organizing framework, while tags fill in the specifics.
Now let‘s move beyond the defaults and explore custom taxonomies – one of the most powerful features in WordPress.
3. Custom Taxonomies in WordPress
While the default categories and tags work great for simple blog-style sites, you may need more advanced and customized taxonomies for structuring diverse content types.
Custom taxonomies allow you to tailor-make the perfect taxonomy structure for your content. Many popular WordPress plugins utilize them:
| Plugin | Custom Taxonomy |
|---|---|
| WooCommerce | Product categories |
| WPForms | Form tags |
| MemberPress | Member types |
For example, an online course platform could use custom taxonomies like:
- Subjects (Design, Development, Business)
- Level (Beginner, Intermediate, Advanced)
- Delivery (Self-paced, Cohort-based)
Here are some key benefits of custom taxonomies:
- Flexibility – Structure taxonomies beyond categories and tags for custom post types.
- SEO optimization – Fine tune taxonomy to focus on industry or niche keywords.
- User experience – Create a custom organization system tailored to your content and audience.
- Unlimited options – Craft as many custom taxonomies needed for your site.
However, custom taxonomies may require more development work compared to the ease of default categories and tags. Here are some examples of sites that can benefit from custom taxonomies:
- Knowledge bases and online courses
- Directories and membership sites
- Ecommerce stores
- Industry publications
- Wikis and documentation portals
Take your time to strategize the right custom taxonomy structure for your content from the start.
Taxonomy Best Practices for SEO
Optimizing your WordPress taxonomy is crucial for unlocking the full SEO potential of your site.

Properly structured taxonomies have immense benefits for both user experience and search engine optimization.
Taxonomy Tips to Enhance User Experience
Taxonomies also have UX implications beyond SEO. Follow these guidelines:
- Order categories and tags alphabetically or logically.
- Be consistent with names – capitalization, plural vs. singular, etc.
- Make taxonomy names self-explanatory.
- Use hierarchical categories to break down broad topics.
- Don’t overuse categories and tags – keep them relevant.

With custom taxonomies, educate users on any new organization systems you introduce. Good taxonomy nurtures both SEO and UX.
