Find Duplicates


A plugin that finds duplicate and similar posts based on their post_content or post_title similarity. You can define the percentage of similarity, post type and post status. The plugin is a great utility to find duplicates that differ in only a few characters.

  • Search for duplicate posts
  • Search for similar posts
  • Define post types
  • Define post statuses
  • Define value of similarity
  • limit by date
  • Support for custom post types
  • Two-click-delete posts in result list
  • Multi-language interface


  • Find duplicates
  • Find duplicates settings page


  1. Upload the folder find-duplicates to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Use the new menu item appearing under ‘tools’


A way to run it in Cron?

The calculation of content similarity is an time-consuming task.
Therefore we get problems with the execution time while doing ist with cron-jobs.
While comparing articles through the interface we can use ajax to avoid this.
