Duplicate category titles on your WordPress website can negatively impact both user experience and SEO. When multiple pages display the same category title, it confuses visitors and search engines alike. This guide will help you understand the causes and provide step-by-step solutions to fix this issue, ensuring your site remains user-friendly and search engine optimized.
Duplicate category titles typically occur due to the following reasons:
1. Theme or Plugin Conflicts - Themes or plugins can sometimes generate multiple instances of the same category title across different pages.
2. Incorrect Permalink Settings - Misconfigured permalinks can lead to duplicate titles, especially if they aren't set up to include unique identifiers like post IDs or slugs.
3. Taxonomy and Query Issues - Custom taxonomies or queries not properly set up can cause duplication in category titles.
4. Database Errors - Corrupt or improperly configured database entries can also result in duplicate titles.

Before diving into solutions, it's important to diagnose the root cause of the issue. Follow these steps:
1. Check Theme and Plugins - Deactivate all plugins and switch to a default theme (like Twenty Twenty-One) to see if the issue persists. If it resolves, reactivate each plugin one by one and switch back to your original theme to identify the culprit.
2. Review Permalink Settings - Go to Settings > Permalinks in your WordPress dashboard and review your permalink structure. Ensure it includes unique elements to prevent duplication.
3. Inspect Taxonomies and Queries - If you are using custom taxonomies or queries, review their configurations. Ensure they are set up to generate unique titles.
4. Examine the Database - Use phpMyAdmin or a similar tool to check for duplicate entries in your database. Look for inconsistencies in the wp_terms and wp_term_taxonomy tables.
Once you've identified the cause, you can apply the appropriate solution:
1. Fixing Theme or Plugin Conflicts - If a theme or plugin is causing the issue, contact the developer for support or look for updates. You might need to find an alternative if the issue persists.
2. Adjusting Permalink Settings - Ensure your permalink structure is SEO-friendly and unique. A common format is /category/post-name/ which helps avoid duplication. Update the permalinks and regenerate them by saving changes in the Permalink settings.
3. Correcting Taxonomies and Queries - Ensure custom taxonomies are uniquely identified. If using custom queries, make sure they include unique parameters to avoid duplication. Example:
$args = array(
'taxonomy' => 'category',
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => false,
'exclude' => array(),
'include' => array(),
);
4. Database Cleanup - If there are duplicate entries in your database, remove them carefully. You can use plugins like WP-Optimize to clean up your database, or manually delete duplicates via phpMyAdmin.
