Unique Title Checker is a WordPress plugin designed to ensure that the titles of new posts, pages, or other post types are unique. This utility is particularly useful for content creators who want to avoid duplicate titles across their website. The plugin enhances the functionality of the original Duplicate Title Checker by allowing users to check for unique titles not only in posts but also in pages and custom post types, broadening its applicability for various content types.

The plugin features a customizable filter called unique_title_checker_arguments, which permits users to modify the WP_Query arguments to expand the search for duplicate titles beyond the current post type. This flexibility makes it a valuable tool for WordPress site managers looking to maintain a consistent and unique title structure across their content, ultimately enhancing the user experience and SEO performance.
