Carousels, or image sliders, have become a familiar feature on websites, allowing multiple pieces of content—such as images, text, or video—to rotate within a single space. They’re popular for showcasing products, announcements, or promotions on homepages and landing pages. However, to truly leverage the power of a carousel, it’s important to use it effectively. Misusing a carousel can lead to low user engagement, poor website performance, and a negative impact on SEO.
In this article, we will explore the best uses of carousels, when and where they can be most effective, and how to avoid common pitfalls.
Understanding the Carousel in Web Design
A carousel is a rotating display feature that showcases multiple slides of content within a set frame. The content can automatically cycle through or allow users to manually click through each slide. Despite their prevalence, carousels can be a double-edged sword: used correctly, they can grab attention and highlight key content; used poorly, they may frustrate users and degrade performance.
The Benefits of Carousels
Before we dive into the best practices, let’s consider why carousels remain popular in certain scenarios:
- Efficient Space Utilization: Carousels allow websites to showcase multiple messages, products, or images in a single section, maximizing screen real estate.
- Visual Appeal: When designed well, carousels can be visually striking and help grab users’ attention, particularly for first-time visitors.
- Content Prioritization: Carousels provide a solution for featuring multiple priority items on the homepage without cluttering the design.
That said, not every website or piece of content benefits from a carousel. To make them work, you need to follow specific strategies to enhance user experience, boost engagement, and support SEO.
Best Uses of a Carousel
To ensure a carousel is effective and not counterproductive, it’s essential to use it in situations where it adds value rather than creates distractions. Here are some of the best uses for a carousel:
1. Showcasing Featured Products or Services
One of the most common and effective uses of a carousel is in e-commerce. A carousel can display a rotating collection of featured products, promotions, or new arrivals. This allows users to quickly browse through a selection without navigating away from the homepage or landing page.
Example:
An online clothing store can use a carousel to highlight seasonal collections, special offers, or trending items, with each slide linking directly to the product page. This encourages users to engage with the content and explore more deeply.
2. Highlighting Multiple Promotions or Announcements
For businesses running simultaneous promotions, a carousel can showcase different offers in a seamless, organized manner. Whether you’re promoting sales events, limited-time offers, or announcements, a well-designed carousel can keep your visitors informed without overwhelming them.
Example:
A software company might use a carousel to promote various subscription plans or new features, providing users with easy access to more detailed information about each offering.
3. Portfolio or Case Studies Display
For designers, photographers, or creative agencies, a carousel can act as a digital portfolio, showcasing various projects or case studies. This allows potential clients to view multiple examples of your work without needing to click through several pages.
Example:
A photographer’s website could use a carousel to display a range of recent photoshoots, each slide featuring different photography styles or locations. Visitors can easily browse through different projects and click for more details if needed.
4. Customer Testimonials and Reviews
Social proof, such as customer testimonials and reviews, is an important element for building trust with new visitors. A carousel can rotate through several customer stories, showcasing how your product or service has positively impacted others.
Example:
A service-based business, like a marketing agency, can use a carousel to highlight testimonials from satisfied clients. Each slide could feature a client’s photo, a brief review, and a link to their case study.
5. Event Promotions or News Updates
Websites with frequent news updates, event promotions, or new blog posts can use a carousel to feature the latest content. This is particularly useful for news websites, event organizers, or businesses with dynamic, frequently updated content.
Example:
A conference website might use a carousel to feature upcoming sessions, keynote speakers, or important announcements, with each slide linked to a detailed page where users can learn more.
6. Showcasing Key Features of a Product
When launching a new product or app, a carousel can be a great way to present its core features or functionalities. By breaking down the information into separate slides, you can keep the content digestible and visually appealing.
Example:
A tech company launching a new app might use a carousel to walk users through its main features, such as its interface, unique tools, and benefits. Each slide could focus on one feature with relevant images or video.
7. Storytelling or Campaign Messaging
Carousels can also be effective for storytelling—especially for brands running marketing campaigns or advocacy initiatives. By breaking down the campaign message into smaller chunks, the carousel can guide the user through the narrative.
Example:
A non-profit organization might use a carousel to tell the story of their latest fundraising campaign, each slide featuring different elements of their mission, impact, and how visitors can get involved.
Best Practices for Using Carousels
If you decide to implement a carousel on your website, it’s important to follow these best practices to ensure the feature delivers value:
- Limit the Number of Slides: Keep the carousel concise with no more than 4–5 slides. Too many slides can overwhelm users and reduce engagement.
- Include Clear CTAs: Every slide should include a clear and compelling call-to-action (CTA), encouraging users to click through for more information.
- Manual Navigation: Avoid autoplay features. Instead, allow users to control navigation by clicking through the slides manually. Autoplay can frustrate users and make it hard to focus on a specific slide.
- Mobile Optimization: Ensure the carousel works well on mobile devices. Buttons should be easily clickable, and images should scale properly.
- Prioritize Load Speed: Carousels can slow down your page load time if not optimized. Compress images and use lazy loading to improve performance.
- Ensure Accessibility: Make sure your carousel is accessible for all users. Implement keyboard navigation, alt text for images, and readable text for screen readers.
Conclusion
While carousels can still play a role in modern web design, they must be used strategically to be effective. The best use of a carousel is in situations where you need to showcase multiple products, features, or pieces of content in a visually appealing and interactive way. From e-commerce promotions to showcasing portfolios or product features, carousels can be a valuable tool—when designed with user experience, performance, and accessibility in mind.
To make the most of a carousel, focus on concise, engaging content, clear calls-to-action, and an optimized design that performs well across devices. Used correctly, a carousel can help capture attention and drive engagement without negatively affecting website performance.
