Random Content is the easiest way to keep your WordPress site feeling fresh and dynamic. Create content groups, add as many items as you want, and display a random selection anywhere on your site with a single shortcode or widget.
Every time a visitor loads the page, they see something different. That means higher engagement, more clicks, and a site that never feels stale.
<h4>What can you do with it?</h4>
<ul>
<li>Rotate testimonials — Show a different customer quote on every page load</li>
<li>Randomize banners — Keep sidebar and header promotions fresh without manual updates</li>
<li>Cycle CTAs — Test different calls-to-action to see what gets clicks</li>
<li>Display tips or quotes — Add variety to any page, post, or widget area</li>
<li>Shuffle FAQs — Surface different questions each visit</li>
</ul>
<h4>Free features</h4>
<ul>
<li>Display random content anywhere with the <code>[random_content]</code> shortcode</li>
<li>Use in posts, pages, sidebars, or widget areas</li>
<li>Organize content into groups for separate rotation sets</li>
<li>Control how many items display at once</li>
<li>Full WordPress editor support — text, images, HTML, shortcodes, embeds</li>
<li>Lightweight and fast with built-in caching</li>
<li>No coding required</li>
</ul>
<h4>Getting started</h4>
<ol>
<li>Create entries under the Random Content post type</li>
<li>Organize them into Groups (works like categories)</li>
<li>Add <code>[random_content group_id="123"]</code> wherever you want random content to appear</li>
</ol>
That’s it. Your content rotates automatically on every page load.
<h4>Need more control?</h4>
<a href="https://randomcontentpro.com/" rel="nofollow ugc">Random Content Pro</a> gives you complete control over what visitors see and when they see it:
<ul>
<li>Scheduling — Set start and end dates so content appears and disappears automatically. Run time-limited campaigns without touching your site.</li>
<li>Visitor targeting — Show different content based on user role, login status, UTM parameters, referrer, or page type.</li>
<li>Frequency controls — Prevent the same item from showing twice in a row. Set cooldown periods between displays.</li>
<li>Weighted selection — Assign weights (1–10) to each item. Higher weight = shown more often. Perfect for A/B testing.</li>
<li>Display rules — Control visibility per group: logged-in only, specific roles, specific page types.</li>
<li>Fallback content — Define what shows when all items are filtered out. Never display an empty space.</li>
<li>Automatic updates — Get new features and fixes delivered directly to your WordPress dashboard.</li>
</ul>

<h4>Shortcode usage</h4>
Display a random item from all entries: 
 [random_content]
Display from a specific group: 
 [random_content group_id=”64″]
Display multiple items at once: 
 [random_content group_id=”13″ num_posts=”3″]
Load content via AJAX (useful for sites with page caching): 
 [random_content group_id=”64″ ajax=”yes”]
<h4>Widget usage</h4>
Navigate to Appearance → Widgets, add the Random Content widget to any sidebar, and select a group from the dropdown. Leave the group empty to pull from all entries.
