What are testimonials?

Customer testimonials are a positive feedback from a customer, after they’ve bought a certain product or service.

When clients are satisfied with a purchase, they sometimes want to share their positive experience with others.

People tend to mistake positive reviews with testimonials. However, reviews are usually left on a third-party websites, such as Google, Yelp, etc. Also, the customer is the one who comes up with the initiative, with no involvement of the business.

On the other hand, testimonials are usually the idea of the business owners who ask customers for them. They usually appear on the company’s website, their social media pages and so on.

While customer reviews can be negative or positive, testimonials are always a good form of feedback.

Here’s an example of testimonials:

What is a slider?

The design of your site is a crucial element when it comes to driving more traffic. It is the first thing that a user sees when they access your website.

A disorganized, busy website or an ineffective placement of your site elements will make your visitors click away.

That is why you have to make your website as visually appealing as possible.

Sliders are commonly used in web design, for various purposes. A slider is a term used to describe a slideshow and it is a way of displaying content on your site.

It works for any type of content, whether it’s images, text or video and it is a more interactive and attractive way to showcase your content. They can also include buttons, animations, you name it.

Sliders can be simple or more complex. They can be static or as carousels. The content can simply slide horizontally or vertically, one at a time or with one larger, focus image in the center and other smaller, secondary ones below, etc.

Here’s an example of slider from eBay:

A testimonial slider is simply a slider which consists of testimonials from customers. It slides from one testimonial to another and it can be customized to do so in various ways.

Testimonial sliders have a greater visual impact than simply cramming all testimonials on the same page.

Most plugins also offer a lot of configuration options for your sliders. That means you get to choose things like:

  • the type of slider;
  • the duration of each testimonial in the slider;
  • type of navigation;
  • their order (according to date, random, etc.);
  • background;
  • what information to be displayed (full name, location, headshot of the customer, etc.)
  • and so much more;

Where to use testimonial sliders on your website?

If you’re wondering where to place testimonials on your website, there are various ways to use sliders on your pages, and you can see them on various types of websites. However, businesses and more professional sites tend to use them more frequently.

As far as their placement goes, a testimonial slider can go anywhere you see fit: homepage, a product page, a dedicated testimonial page, and so on. But how do you know they’re in the right place?

A little bit of advice: create multiple testimonial sliders that match the pages or sections of your website! For example, on the homepage can be placed general testimonials about the business, while on categories, product pages, checkout pages (and so on), it is recommended to display only testimonials related to the product.

What are the benefits of sliders?

We already mentioned above the importance of visuals and sliders are great design tools in that regard.

Here are the most important benefits of testimonial sliders:

  • they are attractive and visually appealing;
  • they are interactive;
  • sliders are versatile/flexible: you can use them to display any type of content, including images, video, etc.;
