Method 1: Using a Plugin (Recommended for Beginners)

Plugins offer drag-and-drop setup, responsive designs, and easy customization.

Recommended Plugin: Strong Testimonials (Free & Pro)

Strong Testimonials is lightweight, highly rated, and perfect for rotating sliders.

Step-by-Step Setup

1. Install and activate Strong Testimonials from Plugins > Add New.
2. Go to Testimonials > Add New to create your first testimonial:
   • Add client name, photo, company, website, star rating
   • Write the quote in the content area
   • Publish
3. Repeat for 4–10+ testimonials (more = better rotation).
4. Go to Testimonials > Views > Add New.
5. Choose Slider layout.
6. Customize:
   • Transition style (fade, slide)
   • Auto-play speed (e.g., 5 seconds)
   • Show navigation arrows/dots
   • Responsive settings (mobile, tablet)
   • Number of testimonials visible (1–3)
7. Save the view → copy the shortcode (e.g. [testimonial_view id=”123″]).
8. Embed anywhere: Add to homepage, page, or widget using the shortcode or block.

Pro Version (~$89/year): Adds advanced layouts, multiple sliders, random order, filters, and more.

Alternative Plugins:

• Testimonial Rotator (free) – Simple & lightweight
• WP Testimonials with Rotator Widget (free/pro) – Great for carousels
• Slider Revolution (premium) – If you want very advanced animations

Pros: Responsive, easy to manage, works great on mobile. Cons: Free version has basic styling (customize with CSS).

Method 2: Using Custom Code with Testimonials Block (Advanced)

For full control without extra plugins (works with Gutenberg).

Steps

1. Create testimonials as custom posts (use Custom Post Type UI plugin → create “Testimonials” type).
2. Add testimonials with title (client name), featured image (photo), and content (quote).
3. In any post/page, use the Group or Columns block.
4. Add Quote blocks inside.
5. Use Carousel block (from Kadence Blocks or similar) or add this CSS + JS for rotation (via WPCode):
   • CSS (Additional CSS):

CSS.testimonial-slider { position: relative; overflow: hidden; } .testimonial-slide { display: none; } .testimonial-slide.active { display: block; }

1. JavaScript (WPCode – Header):

HTML<script> document.addEventListener('DOMContentLoaded', function() { const slides = document.querySelectorAll('.testimonial-slide'); let current = 0; function showNext() { slides[current].classList.remove('active'); current = (current + 1) % slides.length; slides[current].classList.add('active'); } setInterval(showNext, 5000); // Change every 5 seconds }); </script>

Pros: No extra plugins, full customization. Cons: Requires more setup and maintenance.

Best Practices for Rotating Testimonials

• Keep Quotes Short — 1–2 sentences max for quick reading.
• Add Photos & Names — Real faces build more trust.
• Include Company/Website — Adds credibility.
• Limit Rotation Speed — 5–8 seconds per slide.
• Mobile-Friendly — Disable auto-rotate on mobile or make it swipeable.
• Accessibility — Add ARIA labels and pause on hover/focus.
• Performance — Use lazy loading for images (see our lazy load guide).

A good testimonial slider can increase trust and conversions by 20–40%.
