Common Mistakes in Website Design: What Are They & How to Avoid Them?
1️⃣ Slow Load Speed – Losing Customers Before They Even Arrive:
Users are impatient. So, slow loading speed is one of the top website design mistakes to avoid.
It takes just 0.05 seconds for users to form an opinion about your website. And once they leave, they’re unlikely to come back. Plus, search engines hate slow websites. Google factors speed into rankings, meaning slow-loading sites rank lower—giving your competitors an easy win.
How to Fix it?
✔ Compress images using tools like TinyPNG.
✔ Use a Content Delivery Network (CDN) to speed up loading worldwide.
✔ Minimize unnecessary scripts, plugins, and redirects.
✔ Choose a reliable hosting provider with fast server response times.
2️⃣ Cluttered Layout – Overloading Visitors with Too Much Information:
Another web design mistake to avoid is a messy, overcrowded website. It is like a chaotic store—customers walk in, feel overwhelmed, and walk out. Users need a clear visual hierarchy to find what they need quickly. Otherwise, they leave confused, and you lose a potential sale.
Studies show that conversions can drop by up to 95% if a webpage is cluttered or has too many elements.
How to Fix It?
✔ Prioritize important content by placing key elements in visible areas.
✔ Use whitespace strategically to create breathing room.
✔ Keep navigation simple and intuitive (avoid excessive dropdowns).
✔ Use clear labels (instead of “Products,” say “Men’s Shoes” or “Skin Care”).
✔ Place a search bar in a prominent location for easy access.
3️⃣ Weak Calls to Action (CTAs) – Missing Out on Conversions:
If your CTA says “Learn More” or “Click Here,” you’re not guiding users toward action. Vague CTAs is a top website design mistake to avoid that could confuse visitors, reducing conversions.
Did you know, according to HubSpot’s 15 Call-to-Action Statistics deep dive 15 into over 330,000 CTAs over six months revealed that: Personalized CTAs have a conversion rate that’s 202% better than one-size-fits-all CTAs.
Tips to How to fix it?
✔ Use action-driven language: Instead of “Learn More,” say “Download Free Guide.”
✔ Write the targeted CTAs as per your target audience.
✔ Make CTAs stand out visually with contrasting colors.
✔ Test CTA placements—sometimes, a simple repositioning can boost conversions.
4️⃣ Not Mobile-Friendly – Ignoring Over Half Your Visitors:
According to the gs.statcounter report of Desktop vs Mobile Market Share Worldwide, Over 60% of all web traffic comes from mobile devices, yet another common web design mistakes to avoid are that these websites still break on smaller screens. If your site isn’t mobile-friendly, users struggle to navigate, pinch-zoom, or deal with unclickable buttons—then they leave.
Even worse? Google penalizes non-mobile-friendly sites, pushing them lower in search rankings.
How to Fix It?
✔ Use responsive design so your website adapts to any screen.
✔ Ensure buttons and links are easy to tap on mobile.
✔ Test your site using Google’s Mobile-Friendly Test.
5️⃣ Annoying Pop-Ups & Auto-Play Videos – Driving Users Away Instantly:
Nothing ruins the user experience faster than a full-screen pop-up the second someone lands on a page. A huge website design mistake to avoid.
An even bigger mistake? A loud auto-play video. Users will either close the tab immediately or install ad blockers—meaning you lose conversions and engagement.
Here’s How to Fix It?
✔ Use exit-intent pop-ups instead of immediate ones.
✔ Offer value in pop-ups (discounts, free guides).
✔ Never auto-play videos with sound—give users control.
6️⃣ Generic Stock Images – Killing Authenticity:
We are in 2025, and who still uses stock images? People can spot generic stock photos instantly, making your business seem unprofessional. According to Marketing experiments, Studies show that real images perform 35% better than stock images and contribute to higher user engagement and trust.
So make sure to avoid these top website design mistakes of stuffing your site with stock images.
Here’s how you can do it?
✔ Invest in high-quality custom media.
✔ If using stock images, pick less common, natural-looking photos.
✔ Use team photos or customer testimonials to build authenticity.
7️⃣ Inconsistent Branding – Weakening Your Identity and Trust:
Branding is more than just a logo—it’s the visual and emotional connection your audience has with your business. And, if your website makes the common web design mistake of using different fonts, colors, and logo placements- then visitors will struggle to recognize your brand.
How to Fix It?
✔ Create a Brand Style Guide to ensure uniformity across all pages.
✔ Use the Same Logo and Color Scheme consistently to match your branding.
✔ Maintain Consistent Typography with a primary font for headlines and a secondary font for body text—avoid changing them across different pages.
8️⃣ Poor Readability – Straining Visitors’ Eyes and Losing Engagement:
Another top website design mistake is not following the proper visual hierarchy, contrast, fonts, or stuffing too many decorative elements that make reading difficult. If visitors struggle to read your content, they won’t stick around.
Here’s How to Fix It?
✔ Choose a Readable Font that are easier to read on screens.
✔ Set Proper Font Sizes. For e.g., use at least 16px for body text, with larger sizes for headings.
✔ Improve Line Spacing for better readability.
✔ Use High Contrast for better legibility.
9️⃣ Neglecting Accessibility – Excluding a Huge Audience:
Web accessibility ensures all users—including those with disabilities—can navigate your site. Many businesses make these common web design mistakes to avoid, alienating millions of potential customers who may have visual impairments, mobility issues, or other disabilities. According to the Click-Away Pound Survey, 71% of users with disabilities leave an inaccessible site immediately.
Here’s How to Fix It?
✔ Use Alt Text for Images to describe images clearly for screen readers.
✔ Ensure Keyboard-Friendly Navigation to navigate, not just a mouse.
✔ Provide Captions for Videos for users who are deaf or in sound-sensitive environments.
✔ Improve Color Contrast to ensure text and background colors have sufficient contrast for readability
🔟 Ignoring SEO – Making Your Site Invisible:
A beautiful website is useless if no one can find it. According to HubSpot’s 31 Google Search Statistics, 75% of users never scroll past the first page of search results. So, if you have made the website design mistake of avoiding the SEO optimization you’re making it harder for Google and other search engines to index and rank your site. Ultimately, you’re invisible to most users.
How to Fix It?
✔ Avoid long, messy URLs—use clear, keyword-rich URLs.
