When readers finish reading your blog post, they often reach the end of the page and leave. This sudden exit increases your bounce rate and limits your total pageviews. To keep visitors on your site longer, you can How to Add a Table of Contents to a Blog Post to Boost UX and SEO and point them toward other relevant content. One of the most effective ways to accomplish this is by learning how to add a related posts section in WordPress directly beneath your content.

Historically, site owners relied on third-party plugins to generate related content grids. While convenient, those tools often query your database heavily, adding extra scripts and slowing down server response times. Fortunately, modern WordPress features allow you to build clean, lightweight grids natively without external dependencies.

How to Add a Related Posts Section in WordPress: Why Native Related Posts Matter for Your Blog

Adding automated or manual content suggestions keeps visitors engaged by offering logical next steps. When a visitor finds a post that matches their exact intent, they are more likely to explore additional pages. Keeping site structures efficient also prevents database bloat. If your database grows congested with transient plugin data, you may eventually need to clean your WordPress database to maintain smooth server response times.

Using native blocks avoids the overhead of complex plugins. According to the official WordPress Query Loop block documentation, you can display posts based on specific parameters like a PHP loop without writing any custom code.

Step 1: Open Your Single Post Template

To display related articles automatically at the end of every blog post, you need to edit your theme’s single post template using the Site Editor.

• Navigate to your WordPress dashboard and go to Appearance > Editor.
• Click on Templates and select the Single Post template.
• Open the List View icon in the top toolbar to see your layout hierarchy.
• Locate the Post Content block, which represents the main body of your articles.

Step 2: Insert and Configure the Query Loop Block

Beneath the Post Content block, you will add the block structure that retrieves your related articles.

• Click the (+) block inserter icon right below your content area.
• Search for the Query Loop block and add it to your layout, or type /query loop and press Enter.
• Select the Start blank option or choose a predefined pattern that fits your design preferences.
• Open the block settings sidebar and change the Query Type from Default to Custom if necessary to unlock advanced filters.

Inside your Query Loop, you will find the Post Template container. Official guidance notes that the Post Template block acts as a repeating container holding inner elements like the title, date, and featured image for each returned post.

Step 3: Filter Posts by Category or Tag

A true related posts section should display content that shares a topic with the current article. While dynamic contextual taxonomy filtering depends on your specific theme configuration, you can filter your query parameters directly inside the settings panel.

• Select your Query Loop block and navigate to the Settings sidebar.
• Look for the Filters panel options.
• Choose parameters that match your publishing categories or tags so that readers see relevant topics rather than completely random articles.
• Adjust the number of items shown to three or four posts to keep your layout balanced.

Step 4: Style Your Post Grid Layout

Once your query is filtering properly, refine the visual presentation so it looks professional on both desktop and mobile screens.

• Select the Post Template block inside your Query Loop.
• Switch the layout toggle from List view to Grid view using the block toolbar.
• Add inner blocks such as the Featured Image, Post Title, and Excerpt blocks inside the template container.
• Rearrange these elements using drag-and-drop or the List View panel until you achieve a clean card layout.

Limitations and Honest Cautions

While native blocks offer incredible speed and flexibility, they do have minor limitations. Dynamic related logic based purely on real-time keyword matching can sometimes require advanced taxonomies or custom code configurations. If you choose to enhance your layout with custom styling rules, always make sure to add custom CSS to WordPress safely using block-level styling or your theme customizer to prevent visual bugs.

Test your related section on mobile devices to ensure images scale correctly and text remains readable before publishing your template changes live.

Conclusion

Adding a related posts section in WordPress using native blocks gives you complete control over your design while keeping your server fast and responsive. By leveraging the Query Loop and Post Template blocks, you can successfully guide readers to deeper content, lower your site bounce rate, and increase overall pageviews without relying on heavy external plugins.
