What It Does
Related Posts by Taxonomy scans your posts for shared taxonomy terms (categories, tags, or custom taxonomies) and surfaces the ones with the most overlap as a related content list. It supports thumbnails, shortcodes, and a widget, so you can drop the list into sidebars, post footers, or pages with minimal configuration. The matching is term-based rather than tag-cloud or popularity-driven, which makes it well-suited to content where topic relevance matters more than raw traffic.
Who It's For
This plugin is a strong fit for blogs, news sites, online magazines, and content-heavy publishers that rely on categories and tags to organize articles and want automated internal linking between related pieces. It works particularly well for educational platforms, niche hobby sites, and review sites where readers typically want to drill deeper into a specific topic after finishing a post. If you publish regularly and have a well-structured taxonomy, this keeps readers on-site without manual curation.
Who Should Skip It
If your site relies on views or trending content to define relatedness, or if you use custom post-relation plugins or AI-based recommendation tools, this plugin is a poor fit because its matching is strictly term-based. Sites with very flat or sparse taxonomy structures (one category, few tags) will get weak or repetitive suggestions and should look elsewhere.
The Bottom Line
Related Posts by Taxonomy does one thing reasonably well: matching posts by shared taxonomy terms and rendering them with thumbnails, shortcodes, or a widget, and it has a loyal user base that rates it highly. With active maintenance, modern compatibility, and a clean execution of a narrow feature, it earns a 79.81/100 quality score and is a solid pick for taxonomy-rich publishers. The lack of support threads is a non-issue given the small install count, but anyone needing popularity-based or behaviour-driven recommendations will need a different tool.
Related Plugins
Pick WP Popular Posts instead if you want related or popular lists driven by actual view counts and engagement metrics rather than shared taxonomy terms.
Choose Custom Post Type UI if your priority is registering and managing the custom taxonomies themselves rather than displaying related-content lists.
Choose GenerateBlocks if you want a block-editor toolkit for designing layouts, including related-post sections, rather than a dedicated recommendation engine.
Pick Post Duplicator if you need to clone posts in bulk, which is a different problem from surfacing related content to readers.
Choose Force Regenerate Thumbnails if your goal is rebuilding thumbnail images across the media library, not organizing related posts.
