How to add a review carousel to your website (2026)

Most sites have more good reviews than room to show them. A carousel solves that by fitting a dozen reviews into one strip on the page.

Where it sits matters. 93% of people check online reviews before buying, per our customer feedback statistics, and a carousel puts those reviews on the page they’re already reading.

This guide covers when a carousel beats other layouts, how to build one with real screenshots, and the design details that get it read.

The short version:

• Use a carousel when space is tight. Use a review wall when you want lots of proof on one page.
• Build it in WiserReview: add a carousel, filter the reviews, style it, then copy the JavaScript, iframe, or URL.
• Place it near a decision, such as beside pricing or above a buy button.

What is a review carousel?

A review carousel is a widget that shows customer reviews as cards in a sliding row, moving automatically or when visitors click the arrows or swipe.

• Header: your average rating, review count, and where reviews come from, such as Google.
• Cards: stars, a short quote, the reviewer’s name, a verified badge, and a photo when there is one.
• Controls: arrows, position dots, and a pause button for auto-rotation.

When should you use a carousel instead of another layout?

Use a carousel when you want several reviews in a small space. Pick a different layout when you have room for more, need just one quote, or only have space for a rating.

• Carousel: you have plenty of reviews but room for only one strip, and a full list would push the main button down.
• Review wall: a dedicated reviews page, where visitors came to read a lot.
• Single quote: landing pages that need one strong testimonial beside the form.
• Rating badge: headers, footers, and checkout, where there’s only room for a number.

Many sites use two together, such as a rating badge in the header and a carousel further down.

To add a review carousel with WiserReview, bring in your reviews, add a Carousel widget, filter and style it, then paste its embed code into your website.

Here’s every step, with screenshots from the WiserReview dashboard. Watch this quick overview of WiserReview first, then follow along.

Step 1: Create your account

1. Open app.wiserreview.com/signup.
2. Pick your site builder, or the </> tile for any other website.
3. Sign up with your email or Google account.

The 7-day free trial includes the carousel. Paid plans start at $6.75 a month, billed yearly.

Step 2: Bring in your reviews

1. Go to Manage reviews, click Import Reviews, and find Google.
2. Click Login with Google, pick your Business Profile account, and leave Active on so new reviews keep syncing.

3. Moving from another review app? Click Import, pick the platform or CSV, and map the columns.

CSV imports are open during your first 60 days.

Step 3: Publish and tag the reviews

1. Open the Pending tab and publish the reviews you want to show. Carousels only show published reviews.
2. Tag reviews by topic, such as a product line or service, so each carousel can pull the right ones.

Step 4: Add a Carousel widget

1. Click Widgets in the left menu.
2. Find Carousel and click Manage, then Add widget.

3. Name the carousel after the page it’s for, such as “Homepage,” and click Create.

Step 5: Choose which reviews show

1. Open Filter Reviews.
2. Pick a Review source. Choose Google for a Google reviews carousel, or leave it on All.
3. Under Show reviews by tags, choose the tags that match the page.
4. Use Advanced filters for extra rules, such as a minimum star rating.

Step 6: Style the carousel

1. Set colors for stars, buttons, and arrows in Color, or let AI Design match your site.
2. Change card style in Cards and the overall look in Layouts.
3. Switch the preview from sample data to Real data and check it.
4. Click Install in the top right.

Step 7: Copy the embed code

1. On the Javascript tab, click the copy icon. This works for most websites.

2. If your site builder blocks scripts, use the iframe tab instead.

3. Need a link instead of an embed? Copy the URL to share the carousel in an email or behind a “See what customers say” button.

Step 8: Paste the code into your website

1. Open the page in your site builder and add an HTML or embed element where the carousel should go.
2. Paste the code, save, and publish. The screenshot shows Webflow’s Code Embed Editor.

Here’s where the code goes on common platforms. Each name links to a full walkthrough.

Platform	Where to paste the carousel
WordPress	A Custom HTML block in the page editor
WooCommerce	A Custom HTML block on any page, with the WiserReview plugin handling product page widgets
Shopify	The WiserReview app, then add the widget in the theme editor
BigCommerce	An HTML widget in Page Builder
Wix	Add, then Embed Code, then Embed HTML
Squarespace	A Code Block in the section you want
Webflow	A Code Embed element, then publish
PrestaShop	Your theme template file, where the carousel should appear
Any HTML site	The page body, where the carousel should appear

Step 9: Check it on the live page

1. Open the published page and click through a few cards.
2. No carousel? Go back to Install and click Debug on site.

Extra setup for custom-built stores

The steps above work on any website. On a custom-built store, a few more pieces attach reviews to the right products and keep new ones coming in.

1. Open any product widget, click Install, and on the Custom tab add the pixel code once, just before the closing </body> tag.

2. Paste the product widget code into your product template and fill in each product’s ID.
3. Sync your catalog through the Product Sync API in our custom ecommerce integration guide, so reviews show product names and images.

4. Go to Automate, click Configure on the custom website automation, and have your developer send each new order to its webhook.

Where should a review carousel go?

A review carousel works best near the decisions on a page: below the homepage hero, beside pricing, above a product’s buy button, and right before a form or booking button.

• Below the homepage hero: the first scroll, before visitors read the details.
• Beside pricing: where cost doubts peak.
• On product pages: under the description, with reviews about that product.
• Before a form or booking button: the last proof before someone commits.

Our guide to adding reviews to your website covers every other placement.

How to design a review carousel people read

A good review carousel shows short reviews, moves slowly enough to read, and lets visitors stop it. Most of that comes down to a few settings.

• Let people pause it: anything that moves on its own for more than 5 seconds needs a pause control under WCAG accessibility guidelines.
• Keep quotes short: two or three lines per card. Long reviews get cut off mid-rotation.
• Keep 8 to 12 reviews in the loop: enough variety without a loop nobody finishes.
• Fit one card per screen on phones: 70% of Black Friday 2025 sales came from mobile, per our mobile commerce statistics, and three squeezed cards are hard to read.
• Label the source: a Google logo or verified badge on each card tells visitors the reviews are real.
• Include a photo review: photos make the whole row more believable.

Can a review carousel show stars in Google search?

A review carousel on its own won’t put stars in Google search. Google shows review stars for products, not for reviews a business shows about itself on its homepage or service pages.

If you sell products, the product review section can add Product review schema to each product page. Our guide to review rich snippets explains the rules.

Common review carousel mistakes

• Showing only 5-star reviews while implying they’re all of them, which breaks the US FTC review rule.
• Putting the carousel in the footer, where few visitors scroll.
• Using the same carousel on every page, even when the reviews don’t match the page.
• Adding two carousels to one page, which slows it down.
• Pasting both the script and the iframe for the same carousel, so it loads twice.

Wrap up

A carousel earns its spot when you have more reviews than room. Once it’s live, new reviews keep it fresh without you touching the page again.
