Related content plugins are hard to build, often resource intensive, and overall, just not very great a lot of the time. Related Posts for WordPress from Barry Kooij is an exception to that, however. His plugin for displaying related content for your posts, pages, and any other custom post type, is really top notch.
In this quick video review, I walk you through the plugin, show you how to set it up, and discuss some of the nice features it includes.
Overall this is a great plugin that I happily give a full five stars. Don’t forget that there is also a free version available on WordPress.org that you can use at no cost to get an idea of how well it works.
