nrelate Related Content by nrelate slipfire and sbruner is based on patent-pending technology that continuously analyzes your website content and displays other related posts from your website. This ultimately leads to higher page-views for your site, and a better user experience for your visitors.
Once activated, the nrelate servers will immediately begin analyzing your website content and associating similar articles.
There are four ways to display related content:
1. Automatically display before or after each post.
2. Use the [nrelate-related] shortcode in your post.
3. Use our widget in any widget area in your theme
4. Place the nrelate_related() function in your theme files.
And two display styles:
1. Thumbnails
2. Text
Advertising is also possible with the plugin. Ads come with the same display options as the related content and are a great way to earn a little extra income from your blog.
All of the processing and analyzing runs on nrelate servers.
