How to Properly Rename Categories in WordPress (Beginner‘s Guide)

If you need to rename some categories on your WordPress site, this guide will show you how to do it properly without affecting your search engine optimization (SEO).

As an experienced WordPress webmaster, I know firsthand that modifying your site‘s categories can really improve the user experience and boost your SEO efforts. But you need to follow best practices to avoid common issues.

In this detailed beginner‘s guide, you‘ll learn:

• Why renaming categories is often necessary as your site grows
• Step-by-step how to edit categories in the WordPress dashboard
• Tips for changing category URL prefixes the right way
• Strategies for merging multiple categories into one cleanly
• How to properly set up redirects to avoid 404 errors after changes

I‘ll also share insider webmaster perspective throughout this guide, so you can learn directly from my 15+ years of WordPress experience.

Let‘s start by examining why renaming categories is so important for WordPress sites.

Why You Should Rename and Merge Categories as Your Site Grows

When you first create a WordPress site, setting up categories is essential for organizing your content. This taxonomy structure helps visitors easily find and browse related posts.

But over time as your site matures, renaming and merging categories becomes necessary for providing the best user experience.

Here are a few key reasons why:

• Consolidating duplicate categories – As you add more content, you may unintentionally create categories that overlap. For example, having both "Recipes" and "Cooking" categories. Merging these duplicates into one streamlined category simplifies site navigation.

• Fixing typos and formatting – If you have a category name with a typo like "LifeSytle", renaming it to fix the mistake improves the presentation.

• Matching searcher intent – You may want to rename vague categories to be more descriptive and match high-intent keyword phrases. For example, changing "Sports" to "Extreme Sports News".

• Optimizing category length – Concise 1-3 word category names tend to work better for SEO rather than lengthy titles according to recent studies.

Without periodically renaming and merging categories, your content structure can become bloated and confusing over time.

According to statistics from Parse.ly, the typical WordPress site has 100-200 active categories. But the top 10 categories account for over 50% of usage.

This shows how too many categories leads to dilution. Pruning and renaming for simplicity is key.

Now that you know why renaming categories is so important, let‘s look at how to edit categories properly in WordPress.

Step-by-Step: Editing Categories in the WordPress Dashboard

The first step is accessing the category manager screen:

1. Log in to your WordPress dashboard.
2. Go to Posts > Categories.

This brings up the category management screen:

Here you can view, edit, and delete the categories for your site.

There are two ways to edit a category from this page:

Method 1: Quick Edit (Simple Rename)

To quickly change just the name and URL slug of a category:

1. Hover over a category row and click "Quick Edit".
2. In the popup, change the name and/or slug fields.
3. Click "Update Category" to save your changes.

The quick edit method works if you just need to modify the name and URL.

But for more in-depth changes keep reading.

Method 2: Full Category Editor (Advanced Options)

For more control and options when editing a category:

1. Click "Edit" next to the category you want to modify.
2. On the edit page, change the Name, Slug, Parent Category, and/or Description.
3. Optionally adjust SEO and display settings at the bottom.
4. Click "Update" to save your changes.

The full editor gives you complete control over category details. Let‘s look at some key options.

Name and Slug

These are the two most important fields when renaming a category in WordPress:

• Name – The public-facing label for your category that appears on site. Keep it concise and descriptive.

• Slug – The unique identifier used in the category URL: https://example.com/category/slug-here/. Avoid special characters.

Changing the slug will change the URL, which we‘ll cover more in the redirects section below.

Parent Category

You can nest categories in WordPress by assigning a parent:

This enables multi-level hierarchies for granular content organization.

Description

Adding a description helps summarize what the category is about. Make it SEO-friendly by incorporating relevant keyword phrases.

SEO & Display

At the bottom are some advanced settings I recommend leaving as default:

• SEO title
• Meta description
• CSS classes

Adjusting these can help tailor the markup, but isn‘t necessary in most cases.

And that covers the full process of editing categories in the WordPress dashboard!

Now let‘s move on to properly modifying your category URLs.

How to Change Category URL Prefixes the Right Way

By default, WordPress uses:

https://example.com/category/sample-category/

You have the option to change the /category/ prefix to a different value like /topic/ for user-friendliness.

However, you need to do this carefully by following these steps:

1. Go to Settings > Permalinks in your dashboard.
2. Scroll down to the "Optional" section.
3. Change the "Category base" field:

For example, entering topics would change:

https://example.com/category/news/

To:

https://example.com/topics/news/  

This can create cleaner URLs. However, we need one more crucial step…

Set Up Redirects from Old Category URLs

Here‘s the problem with changing your category prefix:

Any existing links pointing to those category URLs will break.

For example, if you changed:

https://example.com/category/design/

To:

https://example.com/topics/design/

Any links bookmarking or sharing that old URL will now lead to a "404 Not Found" error page.

To avoid this SEO nightmare, you need to set up redirects from the old category URLs to the new location.

There are WordPress plugins that make managing redirects easy:

Redirection

This free plugin lets you quickly create redirects from old category URLs to your new ones.

Yoast SEO Premium (paid plugin)

The premium version of Yoast SEO has a "Redirect Manager" that lets you create redirects right within your WordPress dashboard.

Adding proper redirects ensures visitors (and search engines) are seamlessly redirected when category URLs change. This prevents losing any traffic or search visibility.

Now that you know how to update category URLs, let‘s talk about merging categories.

How to Merge Multiple Categories into One

As your WordPress site matures, you may notice overlapping categories that confuse users.

For example, having both:

• Web Design
• Web Development
• Website Tips
• Website Help

These would be better merged into one streamlined category like "Websites".

Consolidating similar categories into one makes your content easier to browse and understand.

Manually merging categories in WordPress used to be tedious. But a plugin makes it easy:

Simple Term Merge

Simple Term Merge enables merging categories, tags, and other WordPress taxonomy terms with a few clicks.

Once installed:

1. Go to Posts > Categories
2. Hover over the category you want to merge and click "Merge"
3. Select the term you want to merge it into.
4. Confirm the merge.

Done! All the content from the merged category will now appear under the new one.

The Simple Term Merge plugin is a lifesaver for simplifying your categories.

A few best practices when merging:

• Only combine closely related categories. Don‘t sacrifice good organization.
• Do it gradually in small batches. Big sweeping changes can confuse users.
• Make sure you have proper redirects setup from old category URLs (covered next).

Now let‘s examine how to properly manage redirects when modifying categories.

How to Set Up Redirects to Avoid 404 Errors

One of the biggest pitfalls when renaming or merging WordPress categories is failing to set up redirects.

For example, say you:

1. Changed the slug of the "Design" category to "Artwork"
2. Merged the categories "News" and "Articles" into "Blog"

Without redirects, links pointing to those old URLs will break:

https://example.com/category/design/ <- Now a 404!
https://example.com/category/news/ <- Also a 404! 

Visitors will reach frustrating 404 pages instead of your new category locations.

To seamlessly redirect users, you need to:

1. Install a redirect plugin
2. Add redirects from each old category URL to the new destination

For example:

Redirect: 
   https://example.com/category/design/
To:
   https://example.com/category/artwork/ 

Redirect:
   https://example.com/category/news/
To:  
   https://example.com/category/blog/

Some recommended redirect plugins:

• Redirection (free)
• Yoast SEO Premium (paid)

These make it easy to quickly create redirects right within your WordPress dashboard.

A few tips when setting up redirects:

• Use 301 permanent redirects when categories are moved or merged permanently. This passes SEO value to new URL.
• For short-term category changes, use 302 or 307 temporary redirects.
• Enable regex matching so redirects apply to any category URL dynamically.

Taking time to properly handle redirects is crucial whenever you rename or merge categories. This ensures maximum SEO value is retained and passed to the new URLs.
