The Related Posts via Categories plugin for WordPress is designed to automatically display a list of related posts based on shared categories. This free plugin offers extensive customization options, allowing users to adjust the display order, exclude specific posts or categories, and select post types for related content. It requires jQuery version 1.6 or higher and can seamlessly integrate into various themes. Users can either enable auto-display to show related posts immediately after single post content or manually insert a function into theme files if preferred.

The plugin provides flexibility with settings for the maximum number of related posts, customizable titles, and HTML structure for output. Options for ordering related posts include criteria such as related scores, publication dates, and modification dates. Additionally, the plugin supports multiple languages including English, Japanese, Persian, and Armenian, making it accessible to a diverse range of users.
