As mentioned by <a href="http://yoast.com/articles/wordpress-seo/#relatedposts" title="WordPress SEO and Related Posts " rel="nofollow ugc">WordPress SEO</a> master Yoast:
<blockquote>
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.
</blockquote>
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.
