Does your website utilize categories and tags? Does it use custom taxonomies? If so, this plugin will find similar content 
based on all your taxonomies. There are two ways to show related posts within your page.
<ul>
<li>The first way to show related content on your post is to use the widget provided. This only works when is_single() is true</li>
<li>The second way to show similar content on your site is to use the pk_related_return($post->ID); function which can be 
called programmatically anywhere you wish!</li>
</ul>
The Widget included with this plugin gives you the option to limit the amount of posts; it allows you to determine which 
fields to show: Featured Image, Author, Date, and Excerpt (Title is required); it allows you to determine which 
variant of the featured image to show: thumbnail, medium, large, or full. As of version 2.0, you can now decide whether the 
‘similar posts’ sorting prefers posts that are newer or posts that were created closer to the date of the post you’re 
viewing.
If you find the Widget doesn’t meet your needs or is too limiting, you can call the functionality programmatically using 
this function:
<pre><code>pk_related_return($post->ID, $args);
</code></pre>
Where $post->ID is the ID of the post for which you are wanting to show related articles.
The $args parameter is an array with the following values available to you (more coming soon):
<ul>
<li>posts_per_page (int defaults to 5)</li>
<li>thumbnail_size (string consisting of one of these values: “thumbnail”, “medium”, “large”, “full”. Defaults to thumbnail).</li>
<li>sort_prefer (string consisting of one of these values: “newest”, “closest”. Defaults to newest).</li>
</ul>
An example might be:
<pre><code><?php
$args = array (
 'posts_per_page' => 6,
 'thumbnail_size' => 'medium',
 'sort_prefer' => 'closest'
);
</code></pre>
The return value of pk_related_return is an array of objects that includes most of the fields within WordPress’s posts 
table plus permalink and featured image.
Future Additions:
Allow the user to specify only certain content types (posts, pages, custom) in a request. This would allow you to specify 
only products get returned, or only blog posts. This would only be an issue if content types share taxonomies.

Purpose of 404 page is to inform visitor that WordPress cannot resolve current URL, 
but leaves the visitor wondering why. 
Whether the page was deleted or simply the link was not typed correctly.
This plugin analyzes what is entered in the URL, compares it with all existing urls on the site, finds the closest ones and offers the visitor the 5 closest ones. 
Something like “did you mean…”.
<h3>Usage</h3>
The plugin supports both classic and block themes.
For classic themes, you need to add shortcode to the template of your 404 page:
 
For block themes, you will get a new Gutenberg block “404 page: similar links” that you simply insert into your template.
Finally, the plugin allows you to override template to completely customize resulting HTML, 
and a few filter hooks to modify its logic.
