Kandeshop Duplicate Post Manager

Manage and clean up duplicate WordPress posts with ease. Delete duplicates in bulk, assign 301 redirects, and generate .htaccess rules — all from one simple interface.

Features

• Detect duplicate posts by title and slug
• Display all duplicates in a table (with checkboxes)
• Per-post redirect options:
• Choose from other duplicates in a dropdown
• Enter a custom redirect URL manually
• Validate redirect targets before deleting
• Redirect deleted posts using 301 rules
• Save posts to trash, not permanent delete
• Generate .htaccess rules for all redirects
• Copy/paste or export redirects as needed

How to Use

1. Go to Tools > Duplicate Post Manager
2. Click Scan for Duplicates
3. Review the table of duplicate posts
4. For each post:
   • Check the box to delete it
   • Choose a redirect target (dropdown or custom URL)
5. Click Delete Selected & Redirect
6. Scroll down to copy or export your .htaccess redirect rules

Redirect Format

The plugin generates Apache .htaccess rules like:

Redirect 301 /old-slug /new-slug
Redirect 301 /another-old /new-target

• All redirects use relative paths for portability.
• Only valid (non-404) redirects are saved.

Why Use It?

• Prevent SEO penalties from duplicate content
• Control user redirection after cleanup
• Maintain your site』s authority by preserving link equity
• Clean and update old auto-imported posts or legacy content

Technical Notes

• Uses WordPress core functions (get_posts, get_permalink, wp_trash_post)
• Compatible with Classic Editor and Block Editor (Gutenberg)
• Does not delete posts permanently
• Nonce-verified form for security

License

This plugin is licensed under the GPLv2 or later.

Coming Soon (Ideas)

• Export .htaccess as a downloadable file
• Custom post type support
• Integration with Redirection plugins
• Inline AJAX validation of manual URLs
