How to add Testimonials Slider to a One.com Site Builder website

Embed Testimonials Slider on One.com Site Builder

01

Create a Testimonials Slider add-on for One.com Site Builder on Common Ninja

First, create a One.com Site Builder Testimonials Slider add-on on Common Ninja. On the add-ons catalog, find the Testimonials Slider and enter the Editor.

02

Save the Testimonials Slider add-on

When you're done creating the Testimonials Slider add-on, 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 add-on to your One.com Site Builder website, 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 add-on embed code. In the next steps, you will paste this code into your One.com Site Builder website.

04

Paste the code to your One.com Site Builder website’s HTML field.

Next, go to your One.com Site Builder website 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 One.com Site Builder’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 add-on on your One.com Site Builder website.

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 add-on on your One.com Site Builder add-on. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your One.com Site Builder website’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 add-on to your One.com Site Builder website. You can do this by putting it straight into your One.com Site Builder website'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.
