How to Display Related Posts in WordPress

One of the most effective ways to keep readers engaged on your WordPress site is by showing them related posts. Think about it: someone lands on your blog, reads an article, and instead of bouncing away, they see a list of other posts that match their interest. That simple addition can dramatically increase page views, reduce bounce rates, and improve the overall user experience.

In this guide, we’ll explore why related posts matter, the different methods to display them, and practical steps you can take to implement them on your WordPress site. Whether you’re a beginner or an experienced publisher, you’ll find strategies here that fit your workflow.

Key Takeaways

• Choose the right plugin, for example Jetpack, Yet Another Related Posts Plugin, or Contextual Related Posts, to automate accurate related-post suggestions.
• Using clear, well-structured categories and tags helps WordPress identify the most relevant content.
• Optimize placement by displaying related posts at the end of articles or before comments to increase engagement.
• Use thumbnails and excerpts to make related posts visually appealing and improve click-through rates.
• Monitor site performance, because some related-posts plugins can be resource-heavy; consider cached or server-side solutions for faster load times.

Why Display Related Posts?

Before diving into the “how,” let’s talk about the “why.” Related posts aren’t just a design choice; they’re a strategic move.

• Improved engagement: Readers are more likely to click on another article if it’s relevant to what they just read.
• Lower bounce rate: Instead of leaving after one page, visitors stay longer.
• Better SEO signals: Search engines notice when users spend more time on your site, which can indirectly boost rankings.
• Content discovery: Older posts that might otherwise be buried get a second life.
• Monetization opportunities: More page views mean more ad impressions or affiliate clicks.

In short, related posts act like a bridge, guiding readers deeper into your content ecosystem.

Methods to Display Related Posts in WordPress

There isn’t just one way to add related posts. Depending on your technical comfort level, you can choose from several approaches.

1. Using WordPress Plugins

Plugins are the easiest route for most users. They handle the heavy lifting and often come with customization options.

Popular plugins include:

• Yet Another Related Posts Plugin (YARPP): Highly customizable, supports templates, and can display related posts by categories, tags, or even custom taxonomies.
• Contextual Related Posts: Focuses on content analysis to suggest posts based on relevance.
• Jetpack Related Posts: Offers a simple, cloud‑based solution with minimal server load.

Advantages:

• Quick setup without coding.
• Options for thumbnails, excerpts, or text links.
• Often include caching to reduce performance impact.

Potential drawbacks:

• Plugins can add overhead if not optimized.
• Limited design flexibility compared to manual coding.

2. Manual Coding with Theme Files

For developers or those comfortable editing theme files, coding related posts manually provides maximum control.

Steps typically involve:

• Editing the single.php file in your theme.
• Using WordPress functions like WP_Query to fetch posts with similar categories or tags.
• Displaying them with custom HTML and CSS.

<?php
$related = new WP_Query(
  array(
    'category__in' => wp_get_post_categories($post->ID),
    'post__not_in' => array($post->ID),
    'posts_per_page' => 3
  )
);
if($related->have_posts()) {
  while($related->have_posts()) {
    $related->the_post();
    echo '<a href="' . get_permalink() . '">' . get_the_title() . '</a>';
  }
}
wp_reset_postdata();
?>

Advantages:

• Full control over design and logic.
• No reliance on third‑party plugins.

Drawbacks:

• Requires coding knowledge.
• Updates to the theme may overwrite changes unless you use a child theme.

3. Using Page Builders or Theme Options

Modern WordPress themes and page builders often include related post functionality out of the box.

Examples:

• Elementor Pro: Offers dynamic widgets that can pull related posts.
• Divi Builder: Includes modules for post grids and related content.
• Premium themes: Many come with built‑in related post sections.

Advantages:

• Drag‑and‑drop simplicity.
• Consistent design with the rest of your site.

Drawbacks:

• Limited flexibility compared to custom coding.
• May require premium licenses.

4. External Services

Some publishers prefer offloading related post functionality to external services.

Examples:

• Outbrain or Taboola: Provide content recommendation widgets, often monetized.
• Cloud‑based plugins: Jetpack, as mentioned, processes related posts on WordPress.com servers.

Advantages:

• Reduced server load.
• Potential for monetization.

Drawbacks:

• Less control over what’s displayed.
• May show external content if monetization is enabled.

Best Practices for Displaying Related Posts

• Relevance matters: Use categories, tags, or contextual analysis to ensure suggestions make sense.
• Limit the number: Three to five related posts is ideal. Too many can overwhelm readers.
• Use thumbnails: Visual cues increase click‑through rates.
• Keep design consistent: Match the style of your site so related posts feel integrated.
• Test placement: Try below the content, in the sidebar, or even within the text. See what works best.
• Monitor performance: Use analytics to track whether related posts are increasing engagement.

Adding Related Posts with a Plugin

1. Install the plugin
   • Go to your WordPress dashboard.
   • Navigate to Plugins > Add New.
   • Search for “Contextual Related Posts.”
   • Click Install and then Activate.
2. Configure settings
   • Go to Settings > Related Posts.
   • Choose how many posts to display.
   • Select whether to show thumbnails, excerpts, or just titles.
   • Adjust relevance criteria (categories, tags, or content analysis).
3. Customize appearance
   • Use built‑in styles or add custom CSS.
   • Ensure the design matches your theme.
4. Test on your site
   • Open a blog post and scroll down.
   • Check that related posts appear correctly.
   • Adjust settings as needed.

Adding Related Posts Manually

For those who prefer coding, here’s a simplified workflow:

Create a child theme

• Never edit the main theme directly.
• Create a child theme to preserve changes during updates.

Edit the single post template

• Open single.php in your child theme.
• Insert a custom query after the main content.

Write the query

• Use WP_Query to fetch posts with similar categories or tags.
• Exclude the current post.

Style the output

• Wrap results in HTML containers.
• Apply CSS for layout and design.

Test thoroughly

• Check different posts to ensure relevance.
• Optimize for performance by limiting queries.

Performance Considerations

One concern with related posts is performance. Fetching related content can be resource‑intensive, especially on large sites.

Tips to optimize:

• Use caching: Plugins like WP Rocket or W3 Total Cache can help.
• Limit queries: Don’t fetch too many posts at once.
• Consider external processing: Jetpack handles related posts on its servers, reducing load.
• Optimize thumbnails: Compress images to avoid slowing down pages.

Balancing relevance with performance is key.

Advanced Options

If you want to go beyond the basics, consider these advanced techniques:

• Custom taxonomies: Show related posts based on custom fields or taxonomies.
• Content analysis: Use plugins that analyze post content for deeper relevance.
• Machine learning: Some services use AI to recommend posts based on user behavior.
• A/B testing: Experiment with different placements and designs to see what drives clicks.

Conclusion

Displaying related posts in WordPress is more than a design tweak it’s a strategic move to keep readers engaged, improve SEO signals, and maximize the value of your content. Whether you choose a plugin, manual coding, or a page builder, the key is relevance and usability.
