This powerful plugin makes it super easy to manually select related posts for your content. You can search and select posts that fit your criteria, all from within the write/edit post screen.
Creating a system of related items on your website will result in more page views per unique visitor, and will improve Google's understanding of your content.
As mentioned by WordPress SEO master Yoast:
A very good alternative is Microkid's related post plugin, which lets you manually pick related posts. This might cost a bit more time before you hit publish but might very well be worth your while.
You can display related posts automatically underneath your content, use a shortcode or use the widget. Or, if you have some development skills, you can use one of the available API functions for full control of the way related posts are displayed on your website.
With its full support for Custom Post Types, this plugin will work perfectly for both basic and advanced WordPress installations.
