Yet Another Related Posts Plugin
As the title suggests, Yet Another Related Posts Plugin is one of several related posts plugins available for WordPress. YARPP has emerged as the most effective and widely used of this family of plugins. YARPP analyzes the categories and tags of your Posts and automatically generates a list of related Posts at the end of each of your blog entries once you have the plugin installed and set up. Including a set of related Posts tends to keep visitors on your site longer and more fully engaged with your content.
You can set a threshold for the similarity level so that the plugin will not display any Posts unless you meet the minimum level of relatedness that you require. You can also set the plugin to ignore posts that are in certain categories or those with specific tags when determining which posts to display. YARPP is available for download at http://wordpress.org/extend/plugins/yet-another-related-posts-plugin/.
