There are many WordPress related posts plugin available so it is very tough to decide which plugin to use.Since related post is great way of decreasing bounce rate and increasing pages viewed per visit of a visitor so best plugin should be chosen for this purpose.The best related posts plugin for WordPress is SEO Auto Links & Related Posts.
Below are the reasons why you should use this plugin
- The plugin is free.Not a big reason as others are also free but I indicated this to make sure you don’t assume that it is paid plugin
- You can configure the number of related posts to be displayed
- You can exclude categories (mentioning each category name under the configuration screen of the plugin)
- you can show related posts on posts as well as pages
- you can automatically add related posts to your blog feed (a good feature to have)
- It can be configured to query post title and meta tags to find posts related to current post or can be configured to query post content along with post title and post meta tags
- It provides a feature of displaying related posts on 404 pages based on the URl of page queried.for example if the user has looked for a webpage with url http://udinra.com/blog/wordpress-plugin which is not present then a 404 page is displayed with related posts to (wordpress-plugin). You can check this feature using any such URL for Udinra.
- Can customize the CSS
- Can choose to display excerpt and length of excerpt
- Can choose the listing style (numbered or unnumbered)
- It provides additional feature of autolinks in your post content
- You can display post thumbnail
There is only one thing missing in this plugin
- It does not have any widgets so you can not really display related posts in your sidebar but that is not a big problem as most preferable place to display the posts is after the current post.
