How WordPress Handles Duplicate Post Titles

WordPress automatically uses the post title as URL slug.

In case of a duplicate post title, WordPress tries to distinguish the title by adding a number at the end of the URL slug.

Number in the post URL

Since both post titles are still using the same keywords, this could confuse search engines when deciding which post should be ranked for the keywords used in the title.

Avoiding Duplicate Post Titles in WordPress

If you are running a single author website, then you can easily avoid this by simply changing the title and removing the number from WordPress URLs. However, it’s a lot harder to keep track of when you are running a multi-author WordPress site.

But don’t worry, the solution we’re going to cover is going to help you prevent duplicate post titles and advise your authors to change them.

First thing you need to do is install and activate the Unique Title Checker plugin. For more details, see our step by step guide on how to install a WordPress plugin.

The plugin works out of the box, and there are no settings for you to configure.

Simply go to Posts » Add New and enter a unique post title. The plugin will check the post title and notify you that it is unique, and you are good to go.

Unique post title

You can now try again by creating another new post. This time use a title that you have already used for another post.

The plugin will notify you that this title is already been used.

Duplicate post title warning

It will not stop you from editing the post, saving it, or even publishing it.

However, the warning will let you and other authors on your website know that they should use an alternate title.

  2. Any good suggestions for a plugin to check for duplicate content and/or duplicate posts on a WP website?

    Thanks :)

  3. But there are also problems where duplicate contents are developed from category and tags pages what to do about that ?

  4. last comment is over a year old, but WPB have relisted this in a post dated december 2016.

    is this plugin still worthy of a mention when it is untested with the latest release of WP?

    • sorry, thought the last comment was the last post at the bottom,

      Still curious to weather this plugin is being updated to be compatible with the new release of WP

  5. In one of my website, I was not using SEO plugin but I was facing duplicate title, I just customized wp_title() function in header and its done.

  6. for my wordpress 4.0 installation doesn’t go… :( when I write the duplicated title I need to save it to get the message (as in last pic). It seems to ignore it…

  7. This is good to know. I had created a duplicate-2 page on purpose not realizing the detriment it would cause. I changed it and installed the plugin so that I don’t do it again unwittingly. Thanks for the info.
