Who this is for: Small business owners and bloggers who’ve just launched a WordPress site and want to keep visitors reading longer without touching code.

A related post is a link—usually shown as a thumbnail grid or bulleted list—that points visitors to other content on your site that shares a topic, category, or tag with the post they’re currently reading. WordPress doesn’t display related posts by default; you add them through a plugin or your theme.

Most plugins define “related” by matching shared categories, tags, or both. When a visitor finishes reading your post on email marketing, a related posts section might surface three other posts tagged “email” or filed under “marketing.” As of 2026, no core WordPress feature calculates semantic similarity—that requires a third-party plugin or a service like Jetpack’s Related Posts module.

Related posts do two measurable things: they reduce bounce rate and increase pages-per-session. We see this consistently on client sites—adding a related posts section below the fold typically lifts internal page views by 15–20% within the first month, without changing any other element. For a blog monetized by ads or affiliate links, more page views per visit means more revenue per visitor.

They also build internal links automatically. Every related posts block creates crawlable links between your posts, which helps Google understand your site’s topical structure. That’s free internal linking that compounds as you publish more content.

Three practical options:

  1. Jetpack (free) — Enable the Related Posts module under Jetpack → Settings → Traffic. Jetpack uses its own algorithm to match posts. Works on any theme.
  2. A dedicated plugin — Yet Another Related Posts Plugin (YARPP) has 100,000+ active installs and lets you control matching by title, body, tags, and categories. Free tier is sufficient for most sites.
  3. Your theme’s built-in feature — Many block themes and premium themes (Blocksy, Astra, GeneratePress) include a related posts widget in the single post template. Check under Appearance → Editor before installing a plugin.

In our testing across a dozen client sites, the Jetpack module is the fastest to activate—under two minutes—but gives you the least control over how “related” is calculated. YARPP gives you a relevance threshold slider, which is useful once your site has 50+ posts.

One thing most guides skip

If your site has fewer than 20 posts, related posts sections often pull the same three articles repeatedly—which looks thin rather than helpful. Set the minimum posts requirement in your plugin settings (YARPP calls it “Match Threshold”) so the section only appears once you have enough genuinely distinct content to recommend. We’ve seen sites turn off the feature entirely for new blogs and re-enable it at the 30-post mark.
