This plugin makes it super easy to manually select related posts. You can search and select posts that fit your criteria, all from within the write/edit post screen.

Creating a system of related posts/pages on your site will result in more page views per unique visitor, and will improve GoogleBots understanding of your content.

Display related posts automatically, using shortcodes, using widgets or use one of the available API functions to add them to your theme

This plugin supports custom post types.

See the official plugin homepage for Microkids Related Posts for more info and discussion.

Features

• Easily find posts or pages that might be related to the one you are writing with an integrated AJAX powered search utility
• Easily add and remove relations with a single click. No page reloads, no pop-ups
• The relationship created works reciprocal, which means that if post A is added as related to post B, post B is automatically added as related to post A as well (this option can be turned off easily through the settings panel)
• Custom post types support
• Multiple widget support
• Shortcode support: add the [related-posts] shortcode to your post content to display related posts anywhere you want
• Automatically display a list of related posts underneath your posts content. No need to add any PHP tags in your template files, but several functions available for advanced users.
• Flexible customization of the way the related posts are displayed
