This wordpress plugin is the one we use on sitecozy.com to display related posts. First of all, this plugin analyses posts to find related posts based on title and content. Nevertheless, you can also mention the ID of the post that you want to be in the list in the settings of a post page in WordPress.
The related post can include the name of the author, the date, the excerpt. You may decide to display thumbnails, thumbnails + text or only text. The CSS style is the weak point of Contextual related posts. If you want to display the thumbnail and if you want the related posts to be integrated into your theme, you should be ready to use custom CSS styles. That’s why we only decided to show text in the related posts on sitecozy. It was faster to set up. CRP has also a widget.

CRP also uses cache output to prevent slowing down the page load of pages. CRP can also display related posts after a certain number of paragraphs. You can exclude a list of pages, posts or categories from the results.
Webberzone CRP is a good related posts plugin but you should be ready to use CSS styles if you want a stylish display of related posts at the bottom of your pages or in the sidebar.
We compared contextual related posts to other related posts plugins and found that CRP was the plugin that displayed the most accurate related posts. For us, Contextual related post is the best related post plugin for WordPress.
