5 Common Website Design Mistakes And How To Avoid Them.
Table of Contents
Your website has less than 15 seconds to make a first impression. That’s barely enough time for a visitor to scan your homepage, decide if they trust your brand and choose whether to stay or leave. Almost 88% of online consumers are less likely to return to a site after a bad experience. The good news is that most website design mistakes are entirely preventable once you know what to look for.
1. Slow Page Load Time Kills Conversions
Nothing frustrates users more than a dull website. Google research shows that around 53% of mobile users leave sites that take longer than three seconds to load. Every additional second of delay can reduce conversions by up to 7%.
Think about your own or surrounding browsing habits. When you click on a link and the page doesn’t load immediately, most people hit the back button and try the next result. Your potential customers behave exactly the same way.

Why Speed Matters More Than Ever
Search engines now use page speed as a ranking factor. Google’s Core Web Vitals update has made loading performance even more critical for SEO success. Slow websites don’t just lose visitors, they also lose search visibility. Beyond SEO, page speed affects user experience across your entire customer journey. Slow product pages reduce sales.
Common Causes of Slow Websites
- Oversized images: High-resolution photos that have not been optimised for the web.
- Bloated code: Unnecessary CSS and JavaScript files loading on every page.
- Plugin overload: Too many WordPress plugins running simultaneously.
- Poor hosting: Cheap shared hosting that can’t handle traffic rise.
- Lacking compression: Files that are not compressed before delivery to browsers.
How to Fix Speed Problems
- Optimise your images. Compress photos using tools. Implement lazy loading so images only load when users scroll to them.
- Minimise code. Remove unused CSS and JavaScript. Combine multiple files where possible.
- Choose better hosting. Invest in quality hosting with SSD storage and region based servers for faster delivery to customers.
Use a CDN. Content delivery networks store your site files on servers worldwide, reducing load times for international visitors.
2. Mobile Unfriendly Design
Almost 60% of the world’s web traffic now comes from mobile devices. Yet many business websites still provide frustrating mobile experiences that can miss generating sales.
Google switched to mobile-first indexing, meaning they primarily use your mobile version to determine search rankings. If your site doesn’t work properly on smartphones, you are maybe invisible to most potential customers.

Common Mobile Design Mistakes
- Tiny tap targets. Buttons and links that are too small for thumbs to accurately tap. This leads to misclicks.
- Horizontal scrolling. Content that extends beyond screen width forces users to scroll sideways.
- Pop-up overload. Aggressive pop-ups that cover mobile screens make content impossible to access.
- Slow mobile performance. Heavy desktop elements that delay mobile loading times.
Best Practices for Mobile Design
- Design for thumbs first. Make buttons at least 44 pixels tall and wide. Place important actions within easy thumb reach of the bottom screen.
- Use responsive layouts. Implement fluid grids that automatically adjust to any screen size. Test your design on actual devices, not just browser simulators.
- Prioritise mobile content. Mobile users want quick answers. Put your most important information above and make contact details accessible.
- Simplify navigation. Complex dropdown menus don’t work on small screens. Use hamburger menus or sticky navigation that’s always visible.
3. Confusing Navigation Can Lose Visitors
Your website navigation is like big signs in a physical store. Poor navigation creates the digital equivalent of a maze where customers get lost and leave empty handed. Research shows that around 50% of potential sales are lost due to users being unable to find what they’re looking for. Clear and logical navigation isn’t just about user experience but about revenue.
Search engines also use your navigation structure to understand your site. Well organised menus with descriptive labels help with SEO rankings and make it easier for google to index your content.

Common Navigation Problems
- Too many menu items. Overwhelming visitors with navigation options creates hesitation.
- Deep menu hierarchy. Important content buried three clicks deep gets ignored by time pressed visitors.
- Missing search functionality. No way for users to quickly find specific information.
How to Create Clear Navigation
- Keep it simple. Limit main navigation to almost 7 items. Group related content under clear category labels.
- Implement breadcrumbs. Show users where they are and provide easy paths back to main sections.
- Add internal linking. Connect related content with relevant links that guide users through your site naturally.
4. Weak Calls to Action (CTA)
Your call to action (CTA) buttons are the bridge between friendly browsing and making a decision of buying. Weak CTAs are like having a great salesperson who never asks for the sale. Companies with effective CTAs see 121% higher click-through rates compared to organic alternatives. Yet most businesses use uninspiring button text that fails to motivate actual action.
Common CTA Mistakes
- Buried placement. Important CTAs hidden at the bottom of long pages where few users scroll.
- Too many options. Multiple competing CTAs that confuse users about which action to take.
- No visual contrast. Buttons that blend into the background instead of standing out.
How to Improve Your CTAs
- Create visual contrast. Use colours that stand out from your overall design. Make buttons large enough to notice.
- Strategic placement. Position CTAs where users naturally look. It can be above the fold, after compelling content or at decision points in your sales process.
- A/B testing. Test different button colours, text and placements to see what works best for your target audience.
5. Ignoring SEO Fundamentals
Common SEO Design Mistakes
- Missing heading structure. Using heading H1, H2, and H3 tags properly helps search engines understand your content hierarchy.
- Poor image optimization. Missing alternative text makes your site less accessible and harder for search engines to index.
- Weak meta descriptions. Every page needs compelling meta titles and descriptions that encourage clicks from search results.
- Broken internal links. Dead links create poor user experience and signal quality issues to search engines.
How to Fix SEO Issues
- Implement schema markup. Structured data helps search engines display rich snippets of your business information.
- Optimise every page. Each page should target specific keywords naturally within headings, content and meta tags.
- Create accessible design. Use proper colour contrast, descriptive link text and keyboard navigation for users with disabilities.
- Regular maintenance. Monitor for broken links, update contact information and refresh testimonials regularly.
More Common Web Design Trap
- Auto-playing videos. These slow page loading and annoy users, especially on mobile data connections.
- Outdated content. Blog posts from years of not being updated and expired promotional offers make your business look inactive.
- Cross-browser problems. Sites that work perfectly in Chrome but break in Safari or Firefox lose potential clients.
