Related Posts by Taxonomy is a WordPress plugin designed to boost reader engagement by displaying related posts in your sidebar or after the content of your posts. This tool utilizes a widget or shortcode to show posts that share common terms, ensuring that the most relevant content appears at the top. With capabilities to search across multiple taxonomies and post types, users can customize the display using their own templates within a child theme. The plugin is lightweight, ensuring it won’t hinder site performance, and offers extensive documentation for users.

The plugin provides various features including automatic display of related posts, options to include or exclude specific terms, and customization of the post display format (thumbnails, links, excerpts, or full posts). Users can also limit searches by date or post meta and utilize advanced options such as persistent caching, AJAX loading, and the WordPress REST API. With a focus on flexibility and adherence to WordPress coding standards, this plugin can be tailored to meet diverse needs.
