Fix Duplicates

Find and delete duplicates posts. There are extensions that allow you find posts with similar content, redirect duplicates to the post you are keeping

Do you run a site with user submitted content? Do users submit the same post again and again? Use the Fix Duplicates plugin to find and delete duplicate posts.

There is also a paid Redirection extension that preserves the link equity of removed duplicates by 301 redirecting them to the kept item.


The purpose of this plugin is to delete duplicates. Extensive testing has been carried out, but you should make sure you have a backup of your database, just in case.


We currently offer the following premium extensions:

  • Redirection: Gives you the ability to 301 redirect any duplicates being deleted, to the one being kept. This helps preserve your link equity, so that PageRank is passed to a single post rather than just being lost. Or to put it simply: Helps with SEO!


  • This plugin requires WordPress 3.5 or above.
  • I am not currently aware of any compatibility issues with any other WordPress plugins.


The free version of this plugin is officially not supported, but if you leave a comment on the plugin's support forum, I'll try to help if I can. A much higher level of support is available for customers who purchase one of the premium extensions.
