How to Boost Trust with a Native Video Carousel on Your Shopify Horizon Theme

In the world of e-commerce, social proof is everything. Customers want to know that real people are using and enjoying your products before they commit to a purchase. While text reviews are great, nothing beats the authenticity and engagement of video.

If you are using Shopify's new Horizon theme, you want customizations that look sleek, native, and don't slow down your site. A TikTok-style video carousel is the perfect way to showcase user-generated content (UGC) right where it matters most: on your product page.

In this guide, based on the tutorial below, we’ll show you how to easily add a professional video testimonial carousel under your buy buttons using the Section Store app—no coding required.

Why Use a Video Carousel?

As mentioned in the video, this is one of the best ways to add social proof to your product page. The vertical, scrolling format feels incredibly familiar to anyone using modern social media apps. Because it integrates seamlessly with the Horizon theme's aesthetic, it looks native to your store rather than a clunky add-on, instantly building trust with browsing shoppers.

Step-by-Step Guide

Follow these simple steps to get your video social proof up and running on your Horizon theme.

1. Install the Section Store App: If you haven't already, add the Section Store app to your Shopify store. It's a library of premium, no-code sections.
2. Find the Video Carousel Section: Open the Section Store app and browse their library. Look for the "Video Carousel" under the conversion blocks tab.
3. Add to Your Horizon Theme: Click the button to add the section to your theme. Select your active Horizon theme as the destination.
4. Open the Theme Editor: Go to your Shopify admin dashboard, navigate to Online Store > Themes, and click the Customize button next to your Horizon theme.
5. Navigate to the Product Page: At the top center of the theme editor, use the dropdown menu to switch from the "Home page" to the "Products" and select your default product template.
6. Add and Place the Section: On the left-hand sidebar, click "Add block" and select the Video Carousel you just installed. Once added, drag the section block up so it sits directly below your "Buy buttons" or product description for maximum visibility.
7. Customize Content: Click on the section to edit the settings. Change the heading to something engaging like "Our customers speak for us." Upload your video files or add links to your YouTube Shorts/TikTok reviews to populate the carousel.
8. Save and Publish: Hit save, and check your live product page on mobile to see your new, high-converting video social proof in action.
