Delete Duplicate Posts is a plugin for WordPress that does exactly what the name says.
Easy and simple to install and use, the plugin will search for and delete duplicate posts and pages with duplicate titles. You can choose to leave either the first or the latest post behind and delete the rest. All post meta is also removed.
You can run the plugin manually or let it run automatically every hour, cleaning up and sending you details by email.
This free plugin for WordPress was first released September 2nd, 2009 and deletes duplicate posts on your website.
This was inspired by an article I wrote about how to delete duplicate posts back in 2009.
