8 Website Design Mistakes to Avoid When Building or Revamping Your Site in 2024
As we enter 2024, having a well-designed website is no longer optional for businesses that want to succeed online. Your website is often the first point of contact between your brand and potential customers, and a poor design can quickly turn them away. In fact, research shows that 94% of first impressions are design-related, and 88% of online consumers are less likely to return to a site after a bad experience.
Website design mistakes can lead to a lack of credibility, high bounce rates, and ultimately, lost revenue. As an online sales and marketing expert, I‘ve seen countless businesses struggle to gain traction online due to poor web design choices. In this post, I‘ll share the eight most common website design mistakes to avoid in 2024, along with actionable tips for creating a site that engages and converts your target audience.
Mistake #1: Ignoring Mobile-First Design
In 2021, 54.8% of global website traffic came from mobile devices. With the majority of users now accessing the internet on their smartphones, designing for mobile is no longer an afterthought — it‘s a necessity. Yet, many businesses still make the mistake of designing for desktop first and treating mobile as a secondary concern.
Mobile-first design is an approach that prioritizes the mobile user experience and scales up to larger screens. By starting with the constraints of a smaller screen, you‘re forced to focus on the most essential elements of your site and eliminate any unnecessary clutter. This results in a streamlined, user-friendly experience across all devices.
Tips for mobile-first design:
- Use responsive design to ensure your site adapts seamlessly to different screen sizes
- Prioritize content and features based on what‘s most important for mobile users
- Ensure touch targets (buttons, links, etc.) are large enough for easy tapping
- Optimize images and other media for fast loading on mobile connections
- Test your site on a variety of devices to ensure consistent performance
Mobile-First Design in Action: Airbnb
Airbnb is a great example of a company that has embraced mobile-first design. Their mobile site and app are intuitive, easy to navigate, and prioritize the features that matter most to travelers on the go, such as booking accommodations and communicating with hosts.

Mistake #2: Overwhelming Users with Too Many Choices
Have you ever landed on a website and felt instantly overwhelmed by the sheer number of options and calls-to-action? When faced with too many choices, users can experience decision paralysis, leading to higher bounce rates and lower conversions.
According to a famous study by psychologist Barry Schwartz, having too many choices can lead to decreased motivation and satisfaction. In the context of web design, this means that presenting users with too many options can actually discourage them from taking action.
To avoid overwhelming users, aim for simplicity and clarity in your design:
- Limit the number of menu items and navigation options
- Use clear, concise labels for your calls-to-action
- Break up long forms into multiple steps to reduce perceived effort
- Hide less important features or content behind progressive disclosure (e.g., "Learn more" links)
- Prioritize the most important information and actions above the fold
The Power of Simplicity: Google‘s Homepage
Google‘s homepage is a prime example of the power of simplicity. Despite being one of the most complex and powerful technology companies in the world, Google‘s homepage features a minimalist design with just a search bar and a few essential links.

Mistake #3: Poor Visual Hierarchy
Visual hierarchy refers to the arrangement and organization of design elements in order of importance. A strong visual hierarchy guides users‘ attention to the most critical information and actions, making it easy for them to navigate your site and complete their goals.
Common visual hierarchy mistakes include:
- Lack of contrast between important and less important elements
- Inconsistent use of headings, subheadings, and body text
- Poorly placed or designed calls-to-action
- Cluttered or confusing layouts
To create a clear visual hierarchy:
- Use size, color, and placement to draw attention to key elements
- Establish a consistent typographic scale for headings and body text
- Ensure there is ample white space around important content and actions
- Use visual cues like arrows or lines to guide users‘ eyes
- Group related elements together and use spacing to create separation between sections
Applying Visual Hierarchy: Trello
Trello, a popular project management tool, uses visual hierarchy effectively to guide users through its interface. The use of color, size, and placement helps users quickly identify key features and actions, such as creating a new board or adding a card to a list.

Mistake #4: Neglecting Accessibility
Web accessibility refers to the practice of designing and developing websites that can be used by people with a wide range of abilities and disabilities. Neglecting accessibility not only excludes a significant portion of potential users but also opens your business up to legal risk.
Common accessibility issues include:
- Low contrast between text and background colors
- Missing or inadequate alt text for images
- Poorly structured or labeled forms
- Lack of keyboard navigation support
To improve accessibility:
- Follow Web Content Accessibility Guidelines (WCAG) standards
- Ensure sufficient color contrast (aim for at least 4.5:1 for normal text)
- Provide alt text for all informative images
- Use semantic HTML to provide structure and meaning
- Make sure all functionality is available via keyboard
- Test your site with assistive technologies like screen readers
Accessibility Done Right: GOV.UK
GOV.UK, the official website of the UK government, is an excellent example of accessible design. The site adheres to strict accessibility standards, ensuring that all users, regardless of ability, can access essential government services and information.

Mistake #5: Slow Page Load Times
In today‘s fast-paced digital world, users expect websites to load quickly and seamlessly. Slow page load times can lead to higher bounce rates, lower engagement, and ultimately, lost revenue. In fact, a 1-second delay in page response can result in a 7% reduction in conversions.
Common causes of slow page load times include:
- Large, unoptimized images
- Excessive use of plugins or scripts
- Unminified CSS and JavaScript
- Poor server response times
To improve page load times:
- Optimize images for web (compress, resize, and use appropriate formats)
- Minimize HTTP requests by consolidating files and using CSS sprites
- Use caching and content delivery networks (CDNs) to reduce server load
- Minify and compress CSS, JavaScript, and HTML
- Regularly monitor site performance using tools like Google PageSpeed Insights
The Impact of Page Speed: eBay
In a case study by Google, eBay found that just a 100ms improvement in page load time resulted in a 0.5% increase in "Add to Cart" count. For a company the size of eBay, this seemingly small improvement can translate to significant revenue gains.

Mistake #6: Inconsistent Branding
Your website is an extension of your brand, and inconsistent branding can confuse users and erode trust. Inconsistencies in design, messaging, and tone can make your site feel unprofessional and untrustworthy.
Common branding inconsistencies include:
- Varying color palettes or typography across pages
- Inconsistent use of logos or imagery
- Conflicting messaging or tone of voice
- Inconsistent design elements (e.g., button styles)
To maintain consistent branding:
- Develop a comprehensive brand style guide that outlines colors, typography, imagery, and messaging
- Ensure all team members and stakeholders have access to and follow the style guide
- Use templates or design systems to maintain consistency across pages and elements
- Regularly audit your site for any inconsistencies or deviations from the brand guidelines
Consistent Branding in Action: Mailchimp

Mistake #7: Ignoring User Feedback and Analytics
Designing a website is not a "set it and forget it" endeavor. To continuously improve your site‘s performance and user experience, it‘s essential to gather and act on user feedback and analytics data.
Common mistakes in this area include:
- Not providing clear and easy ways for users to provide feedback
- Ignoring or failing to act on user feedback and complaints
- Not setting up or regularly reviewing analytics data
- Making design decisions based on assumptions rather than data
To make data-driven design decisions:
- Implement user feedback mechanisms like surveys, polls, or feedback forms
- Regularly review and analyze user feedback to identify pain points and opportunities for improvement
- Set up web analytics tools like Google Analytics to track key performance indicators (KPIs)
- Conduct user testing and usability studies to gather qualitative insights
- Use data to inform and validate design decisions, and continuously iterate based on results
Data-Driven Design: HubSpot

Mistake #8: Forgetting About SEO
Search engine optimization (SEO) is the practice of optimizing your website to rank higher in search engine results pages (SERPs). Neglecting SEO can limit your site‘s visibility and organic traffic, making it harder for potential customers to find you online.
Common SEO mistakes in web design include:
- Poor site structure and navigation
- Lack of keyword research and targeting
- Missing or inadequate meta titles and descriptions
- Slow page load times
- Non-responsive design
To optimize your site for SEO:
- Create a clear and logical site structure with descriptive URLs
- Conduct keyword research and strategically incorporate relevant keywords into your content
- Write unique and compelling meta titles and descriptions for each page
- Ensure your site is mobile-friendly and loads quickly
- Build high-quality backlinks from reputable sources
- Regularly publish fresh, original content that provides value to your target audience
