CleverNode Related Content


The CleverNode Related Content plugin allows you to display a collection of related articles, picked among those on your own site.
The correlation is made through a semantic algorithm that scans both the title and content of your articles in order to select a collection of related posts.
Articles are displayed as a grid containing the featured image, title and link to the featured article. The position of this grid within the page may be freely chosen.

New in version 1.0.2
Added AMP support: using the official AMP plugin for WordPress and the AMP for WP – Accelerated Mobile Pages plugin, the widget will be rendered as an amp-embed.

To install this plugin download the .zip archive and upload it directly in WordPress Upload Plugin page, or unzip it and use an FTP client to upload the clevernode-related-content folder to your wp-content/plugins directory.


How to activate the plugin?

To enable the plugin, first go to Plugin > Installed plugin, search for the CleverNode Related Content plugin and then click on the “Activate” link.

How to connect to CleverNode?

To connect to the semantic content correlation service CleverNode just click the “Connect to CleverNode” button on the first setup tab of the plugin.
This will place a single call to the CleverNode service endpoint and allow you to get a token, which will be then passed as a parameter to the widget display script.

How does the plugin work?

Once the plugin is connected, a set of meta tags will be added to the head of the individual post. These meta tags will contain the title, URL of the featured image, and the date of posting and are used to create the post element in the widget. They may be disabled if Open Graph data is already present.

The main post content will be tagged by an HTML comment, so that CleverNode will be able to read it, to extract the semantic argument.
Eventually, there will be inserted the script that displays the related posts widget, by default placed at the bottom of the content on individual post pages. It could be displayed in other locations using the [clevernode-related] shortcode.

When the single post page is loaded, this script will make a call to the CleverNode correlation service, passing the post URL and token as parameters, so the service can read the meta tags and content of the post to extract the topic and can send back a JSON with the correlated results for that article.

For more information about the plugin options, you can find the documentation here:

What data is required by the plugin?

The plugin needs the website URL to generate the website token, parse individual posts, and return results, which are semantically related to the specific site.
The URL of the single posts, the meta tags and the name of the identified topic are recorded in our database, for a 15 days from each call, to allow CleverNode to perform the correlation and display the widget.

The plugin does NOT save or use any cookies and NO browsing events are tracked in any way. None of the saved meta tags will be used for purposes other than providing related results, nor transferred to third parties, and NO textual or visual content (HTML or images) will be stored, excluding meta tags as specified above.

For more information about the privacy policy, you can find the documentation here:

What to do if the widget is not displayed?

If the related articles widget is not visible immediately, please try browsing through the articles on your site to give CleverNode time to process the content.
Within a minute or two of browsing, the widget will start to get more crowded. This widget can be found at the bottom of each article or next to the shortcode location.

What to do if the widget appears in the footer of my blog?

If the CleverNode widget does not appear after the single post or in the location where you have placed the shortcode, it could be because of a script optimization plugin. Many of these plugins defer scripts, or place them in the footer. In this case you need to exclude the CleverNode script: //

I started to use this plugin to show related posts on my magazine just a few weeks ago and it started quickly to increase the pages per session rate in my website. I suffer from “one page click and run” users that look for just something they need and leave the website, but since start using this plugin, I got a lot better results. Very easy to set up, I recommend!

I had been looking for a related content solution that was functional, easy to set up and had a nice layout for quite some time. I stumbled upon this plugin by chance with very few reviews and was very doubtful. After installing it I had to reconsider, it is really what I was looking for. Great Work Guys

Compared to all other solutions to create related posts on Wordpress, I like the fact that it is easy to configure, without having to manually link content or categories on my site. Very easy to install it does not require any special configuration and in a few minutes it can make the list of similar content, I tried it with the works section on my site with good results. I also find interesting that the choice is made on a semantic basis as they say… Ultimately I recommend it if you are looking for an effective alternative solution for related posts 🙂
