Duplicate Title Validator is a WordPress plugin that helps maintain the uniqueness of post titles across all post types and taxonomies. By preventing duplicate titles, it enhances search engine optimization (SEO) and improves user experience on WordPress sites. This plugin is compatible with both Gutenberg and Classic Editor, ensuring a seamless integration for users. Key features include comprehensive duplicate detection, clear warning messages that specify the source of duplication, and a draft mode that saves posts with duplicate titles to prevent accidental publishing.

In its latest version 1.6, Duplicate Title Validator has undergone significant improvements, including a restructured plugin architecture for better performance. Users can now access a display of previously used titles to avoid unintentional duplication, and a new dashboard widget helps identify similar or potentially duplicate titles. The plugin also supports localization in English and Persian, making it accessible to a wider audience.
