What is Jetpack Related Posts plugin?
Jetpack Related Posts is a module within the Jetpack plugin that displays related content at the bottom of your WordPress posts. It uses WordPress.com’s infrastructure to analyse your content and algorithmically match related articles, displaying them with thumbnails and titles. Unlike most related posts plugins that query your local WordPress database, Jetpack Related Posts processes content through the WordPress.com cloud.
To use Jetpack Related Posts, you need the full Jetpack plugin installed and activated – it is not a standalone plugin. Enable the Related Posts module in Jetpack → Settings → Traffic → Related Posts. Customisation options include showing or hiding post thumbnails, enabling or disabling the heading, and adding custom CSS for styling.
The main advantage is quality of recommendations – WordPress.com’s content analysis often produces more relevant matches than simple tag or category-based related posts. The main disadvantage is dependency on the full Jetpack plugin, which many site owners avoid due to performance concerns. If you want related posts without Jetpack, standalone alternatives like Yet Another Related Posts Plugin (YARPP) or Related Posts for WordPress are available.

Common Problems & Fixes
Jetpack Related Posts is not showing on my posts. How do I enable it?
Go to Jetpack → Settings → Traffic and verify Related Posts is toggled on. Also check your theme – some themes disable the post footer area where related posts appear. If using a page builder for posts, the related posts output hook may not fire. Try switching to a default theme to test.
Jetpack Related Posts is showing irrelevant content. How do I improve recommendations?
Jetpack Related Posts needs a reasonable amount of content to make good recommendations – sites with fewer than 20-30 posts often see less relevant results. Ensure posts have descriptive titles and content. Jetpack’s algorithm improves as your content library grows. If relevance remains poor, a tag and category-based related posts plugin may produce more controlled results.
Jetpack Related Posts is slowing down my site. How do I disable only this module?
Go to Jetpack → Settings → Traffic and toggle Related Posts off. This disables only the related posts module without deactivating the full Jetpack plugin. You can selectively disable individual Jetpack modules to keep only the features you actually use.
Customization & Developer Notes

Jetpack Related Posts outputs HTML with class jp-related-posts-i2. Target these classes in your theme’s custom CSS. Common customisations: changing thumbnail size (Jetpack options in Settings), adjusting the number of related posts shown (filter in functions.php: jetpack_relatedposts_returned_results), and hiding the default heading.
Can I show Jetpack Related Posts in a different location on my posts?
By default, Jetpack Related Posts appear at the end of post content. To move them, disable automatic display in Jetpack settings and use the jetpack_related_posts_display_markup_and_load_assets() function in your theme template at the desired location. This requires theme file editing.
Frequently Asked Questions
Do I need the full Jetpack plugin for related posts?
Yes – Jetpack Related Posts is a module of the Jetpack plugin, not a standalone plugin. You need the full Jetpack installation. If you want related posts without Jetpack, use YARPP (Yet Another Related Posts Plugin) or Related Posts for WordPress, both available on WordPress.org.
How many related posts does Jetpack show by default?
Jetpack shows 3 related posts by default. Change this using the jetpack_relatedposts_returned_results filter in your theme’s functions.php. Set it to any number from 1 to 7. Higher numbers require sufficient content in your library to fill the recommendations meaningfully.
Does Jetpack Related Posts affect SEO?
Related posts add internal links to your site, which is generally positive for SEO – it helps distribute link equity and helps search engines discover content. The performance overhead from Jetpack itself may have a minor negative impact on Core Web Vitals. On balance, the internal linking benefit is positive for most sites.
What is the best alternative to Jetpack Related Posts without Jetpack?
YARPP (Yet Another Related Posts Plugin) is the most established standalone alternative – it matches related content based on tags, categories, and content similarity. Related Posts for WordPress by TwinCreators is another option. For simple related posts without algorithms, linking manually to 3-5 related articles at the end of each post provides editorial control that algorithms cannot match.
