This lightweight plugin lets you easily display related posts in a sidebar or after posts as thumbnails, links, excerpts or full posts.

== Description ==

Quickly increase your readers' engagement by adding related posts in the sidebar or after post content with a widget or shortcode.

Posts with the **most terms in common** will display at the top! 

This plugin is capable of finding related posts in multiple **taxonomies** and **post types**. Include or exclude terms from the search for related posts. Change the look and feel by using your own templates in a (child) theme.
