How to add Testimonials Slider to a Shopify store

Embed Testimonials Slider on Shopify

01

Create a Testimonials Slider app for Shopify on Common Ninja

First, create a Shopify Testimonials Slider app on Common Ninja. On the apps catalog, find the Testimonials Slider and enter the Editor.

02

Save the Testimonials Slider app

When you're done creating the Testimonials Slider app, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Testimonials Slider Embed Code

When you're ready to add the Testimonials Slider app to your Shopify store, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the app embed code. In the next steps, you will paste this code into your Shopify store.

04

Paste the code to your Shopify website’s HTML field.

Next, go to your Shopify store editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Shopify’s editor. Add it to your page, and paste the Testimonials Slider Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Testimonials Slider app on your Shopify store.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Testimonials Slider app on your Shopify app. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Shopify store’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Testimonials Slider app to your Shopify store. You can do this by putting it straight into your Shopify store's HTML code.

Why Use This Widget

Use the Testimonials Slider widget when you want to show social proof without cluttering your layout. Instead of listing long walls of quotes, you can rotate a focused set of impactful testimonials in a compact section that fits into homepages, landing pages, and product pages. Each slide can highlight a specific result, use case, or customer type, which helps new visitors find a story that feels similar to their own. This builds trust, supports your claims, and gives people reasons to believe you before they reach the pricing or checkout stage. Over time, strong testimonials in the right place can lift conversion rates and reduce hesitation.
