7 Best Free Customer Testimonials Slider Widgets for Websites

Many businesses use customer testimonials on websites.

Why?

Because it works!

In fact, many studies like this one from Spiegel Research Center have shown even five reviews can increase the likelihood of a purchase by 270% compared to products without any reviews.

Still, many people trust what other people say about a particular service or product.

Collecting customer reviews is possible and easy for anyone. Third-party services such as TrustPilot and Google’s Business reviews and online review collection software such as Endasoral can help with that.

In a recent article, we shared how to embed Google reviews on a website.

But, how would you add a testimonials widget to your website?

That is why, in this article, you will find out the top seven free testimonials slider widgets for websites. These testimonial carousel widgets are responsive and can be used on any platform, whether WordPress, Shopify, Brizy, Wix, Weebly, Webflow, Squarespace, or HTML site.

What is a customer testimonials slider widget?

Customer reviews can be collected in many ways.

1. On the website through a form (ex: Endasoral)
2. Google Reviews platform
3. Facebook page reviews
4. Review platforms such as Capterra, TrustPilot, Yelp, Edmunds

Testimonials are positive reviews shared by customers. Embedding these reviews on your site can help in boosting conversions by convincing potential customers who are on the fence to get on.

A standard testimonials slider displays reviews in a carousel by rotating testimonials. Check out the example below.

UpViral uses reviews from famous people in various relevant industries, such as Russell Brunson (from Clickfunnels) and Nathan Chan (from Foundr). Since Upviral is an online sweepstakes software that digital marketers use mostly to generate leads, those reviews from familiar faces weigh a lot.

Using a quality testimonial carousel slider with previous and next preview buttons than a gird style review widget can add more reviews in a small space.

Eight tips to know when using the testimonials slider widget on websites

1. Link to other reviews – You could not display all the reviews on a review web page. But, you can link to all reviews, which could be placed on a dedicated page on your site.
2. Show reviews from recognized people/brands – Reviews from famous and familiar people in an industry can make a bigger impact.
3. Add transparency – Add links to social profiles of reviewers if possible. Use real testimonials by asking customers to drop reviews on popular platforms such as Facebook, Google, Yelp, G2, etc.,
4. Concern about page loading time – Testimonials work as long as it does not ruin the user experience. Suppose you hold a giveaway campaign using a contest tool such as UpViral and want to showcase previous winners’ reviews. In that case, make sure to compress images using a service like ShortPixel, limit the number of reviews to be shown, and load the testimonial slider widget asynchronously (i.e.: after other elements are loaded) so that it will not make a bigger impact on conversion rates.
5. Use feature-specific and benefit-driven testimonials on different sections – Suppose you have a software business. In that case, you can highlight the benefits of each feature by embedding a client testimonial slider related to the specific feature.
6. Negative ratings lend credibility to other reviews – Shoppers are skeptical of overly positive reviews, most shoppers actively seek out negative reviews, and the presence of negative reviews brings authenticity to a site’s review content, so there is no point hiding negative reviews.
7. Verified reviews vs anonymous reviews – Reviews from verified users are more important than those submitted by unverified or anonymous users. So, utilize Google, Facebook, Walmart, Amazon, Ceneo, Reviews.io, and Capterra platforms to obtain relevant and verified user reviews.
8. Split test – You never know which combination performs better with your traffic source(s) unless you split test. Experiment with different placements (i.e., just under signup form/order form, middle of sales page, the bottom of the page, or above the fold (the portion of the web page that is visible without scrolling)), different widget layouts (ex: carousel, rotator, cards), styles, and without pagination and auto-rotation and different rotation times.

Final words on best website testimonial sliders

Just like using a quality interactive Google Map on necessary placements on a website, a customer testimonials slider with auto-rotation can take users’ attention, increase brand credibility and improve conversions.

I use Elfsight and Powr services because they provide free support (24*7), new updates, and additional widget types such as countdown timers, pricing tables, forms, and buttons which are helpful on many occasions.

If you are using a service like Elfsight, consider using a script manager such as Google Tag Manager and Zaraz from Cloudfralre to load the Elfsight script asynchronously, which ultimately helps prevent the JS script from impacting a lot on page speed.
