Frequently Asked Questions

Common questions about Unique Title Checker

Some SEO experts say that you should not have two pages with the same title. If you want to avoid duplicate titles on your website, this plugin can help you with that task, as it checks the uniqueness of page titles before you save or publish a page (or post).
Yes! It was implemented with custom post types in mind. With the default setting, it will check for duplicate titles in the same post type only.
With the default settings, all posts with any post status (even custom ones) will be included in the check, except the statuses "draft", "auto-draft", "inherit" and "trash".
No! You can always save the post. There might be good reasons for you to have duplicate titles on your site. The plugin itself does not influence the saving in any way. Its whole functionality is only based on some AJAX.
Every time you leave the title input field, the plugin will check the uniqueness of the new title, so you know if it will be unique before you save the post.
Absolutely! The plugin provides a filter called unique_title_checker_arguments. With this filter, you can alter the arguments used for the WP_Query, the plugin uses to get posts with duplicate titles.
No, it only checks the uniqueness per post type. But you can customize the WP_Query with the filter mentioned in the previous question. For a check across all post types, you can also use this plugin implementing the filter for such a check.
Yes, you can use the filter unique_title_checker_only_unique_error with __return_true to deactivate it (or use this plugin which implements the filter).
You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team helps validate, triage and handle any security vulnerabilities. Report a security vulnerability.
