To add a testimonial slider in WordPress, install the free SlideVerse plugin and insert the Testimonial Slider & Review Carousel block. Add each quote with the person's name, role, photo and star rating, choose how many show at once, and publish. Use real, specific testimonials with full names — that matters more than the slider design.
Build it
- Install and activate SlideVerse.
- Insert Testimonial Slider & Review Carousel.
- For each testimonial add the quote, author name, role, avatar and star rating.
- Set slides per view — 1 for large quotes, 2–3 for short ones — with separate values for tablet and mobile.
- Choose navigation (dots work well) and autoplay with a delay of 6–8 seconds so people can finish reading.
- Style quote typography, card background and spacing in the Style tab.
- Publish.
Autoplay pauses when a visitor hovers or focuses the slider, and stays off for visitors who prefer reduced motion.
What makes a testimonial believable
| Do | Don't |
|---|---|
| Use the person's real name, role and company | Use "John D., USA" |
| Quote a specific result: "cut our load time in half" | Use generic praise: "Great product!" |
| Use a real photo with permission | Use stock photos |
| Keep the original wording | Edit quotes into marketing copy |
| Link to the source if it's public | Mix invented quotes with real ones |
Many countries' consumer rules — including the US FTC's rule on fake reviews — treat invented or misleading testimonials as deceptive. A few genuine quotes beat a dozen vague ones.
A note on star ratings and schema
Showing stars on your own page is fine. Adding review schema to get stars in Google is different: Google doesn't show review rich results for reviews a business writes about itself, and aggregated ratings copied from other sites break its guidelines. Use testimonials to convince readers, not search engines.
Layout ideas
- One big quote under a pricing table, where doubts are highest.
- Three cards on the homepage, after the features section.
- A continuous wall of short quotes — put cards in the Infinite Slider block, which scrolls like a marquee. Elementor users can use MarqueeX's Testimonial Marquee.
