50 Web Design Mistakes to Avoid for a Better User Experience

Designing a website that’s both visually appealing and user-friendly can be challenging, especially with the myriad of elements that need to be considered. While it's easy to focus on the aesthetics, overlooking functionality can lead to a less effective website. Below, we dive into 50 common web design mistakes and why avoiding them will significantly improve your website’s usability, SEO, and overall success.

1. Misalignment of Titles and Text

Problem: Center-aligning titles with left-aligned paragraph text creates a disjointed appearance that disrupts the flow of reading.

Solution: Maintain consistency by aligning titles and paragraph text to enhance readability.

2. Ignoring Content Wrappers

Problem: Users with wide monitors may find your website unusable if you don't use content containers or wrappers.

Solution: Implement content wrappers to ensure that your website adapts well to all screen sizes, providing a consistent user experience.

3. Inappropriate Use of Line Breaks in Headings

Problem: Adding line breaks in headings to make them look "prettier" often disrupts the natural flow of text, particularly on mobile devices.

Solution: Avoid unnecessary line breaks and prioritize readability over aesthetics.

4. Poorly Positioned Scroll-to-Top Buttons

Problem: Scroll-to-top buttons that hover over footer content can interfere with usability.

Solution: Ensure that such buttons are placed where they don’t obstruct important content, especially in the footer.

5. Excessive Letter Spacing

Problem: While letter spacing can be a design choice, too much space between characters can make text hard to read.

Solution: Use letter spacing sparingly, balancing design with readability.

6. Small Text Areas

Problem: Users often need ample space to type their messages. Small text areas can discourage engagement.

Solution: Provide large text areas to encourage users to provide more information, enhancing communication.

7. Overly Long Headings

Problem: Headings that are as long as sentences violate Google's SEO guidelines and can confuse users.

Solution: Keep headings concise, turning lengthy headings into paragraphs where appropriate.

8. Overreliance on Stock Photos

Problem: Stock photos can make your site look generic and inauthentic. (Table Reference: 67% of consumers find authentic images more trustworthy than stock photos.)

Solution: Use custom or high-quality images that resonate with your brand’s identity.

9. Not Opening External Links in New Tabs

Problem: Failing to set external links to open in new tabs can lead to users leaving your site unintentionally.

Solution: Always configure external links to open in new tabs, keeping users engaged on your website.

10. Skipping HTML Theme Color Settings

Problem: Not setting an HTML theme color is a missed opportunity to align your website with modern standards.

Solution: Update your site to include HTML theme colors, enhancing the visual experience across different devices.

11. Lacking Navigation Back to Parent Pages

Problem: Subpages like team member profiles or project portfolios should have an easy way to navigate back to the parent page.

Solution: Ensure that navigation back to parent pages is clear and intuitive, facilitating better user flow.

12. Sidebar Appearing Before Content on Mobile

Problem: On mobile, if the sidebar appears before the main content, it disrupts the user experience. (Table Reference: 74% of users are more likely to return to mobile-friendly websites.)

Solution: Adjust mobile layouts so that main content appears before the sidebar.

13. Using Large Images on Mobile

Problem: Large images can slow down your mobile site, leading to a poor user experience. (Table Reference: Optimized images can reduce loading time by up to 80%.)

Solution: Create smaller image versions specifically for mobile to optimize loading times and user satisfaction.

14. Unreadable Logos in Sticky Navigation

Problem: When sticky navigation uses a different style, the logo may become unreadable if not adjusted.

Solution: Adapt the logo for sticky navigation, ensuring it remains clear and visible.

15. Missing Captions on Complex Media

Problem: Videos or images covering complex topics should include captions to aid understanding.

Solution: Add captions to make content more accessible and easier to comprehend.

16. Absence of Hover Effects on Buttons

Problem: Hover effects are essential even on mobile, as they indicate to users that an element is interactive.

Solution: Implement hover effects for all buttons to improve usability, even on touch devices.

17. Improper Heading Weight Increment

Problem: Headings that don't incrementally decrease in weight can confuse users and detract from the hierarchy of your content. (Table Reference: Properly structured content can improve user comprehension by 32%.)

Solution: Use the six heading levels (H1-H6) provided by HTML properly to structure your content effectively.

18. Non-Linkable Phone Numbers and Emails

Problem: Users should be able to click phone numbers and emails to initiate a call or email directly.

Solution: Always make phone numbers and email addresses clickable links.

19. Skipping Dedicated Pages for Key Information

Problem: Important pages like contact or pricing should not be buried within other content.

Solution: Create dedicated pages for critical information, making it easier for users to find what they need.

20. Inconsistent Background Colors and Accessibility

Problem: Inconsistent background colors can harm accessibility, especially for users with visual impairments. (Table Reference: 98% of the top million websites fail to meet accessibility standards.)

Solution: Use accessible background colors consistently to ensure your website is usable for everyone.

21. Overuse of Bold Colors

Problem: Having more than two to three bold colors on a website can overwhelm users and make the site visually chaotic.

Solution: Stick to one bold color and use neutral tones like black, gray, and white to create a harmonious and visually pleasing design.

22. Too Many Button Styles

Problem: Using more than three button styles can confuse users and make the site look inconsistent.

Solution: Limit your design to three button styles to maintain a clean and cohesive appearance.

23. Not Designing for Your Demographic

Problem: Failing to consider the needs of your target audience, like seniors who may find accordions confusing, can lead to a poor user experience.

Solution: Tailor your design to your audience’s preferences and capabilities, simplifying where necessary.

24. Misuse of Italics for Quotes

Problem: Quotes, testimonials, and reviews should be clearly distinguished from other content, ideally in italics.

Solution: Use italics to format quotes, making them stand out and improving readability.

25. Navigation Links Without Parent Pages

Problem: Using a hashtag as a link in navigation without linking to a parent page can confuse users.

Solution: Create landing pages for navigation items that lead to subpages, establishing a clear URL hierarchy.

26. Inconsistent Capitalization

Problem: Using text-transform to make all text uppercase without proper capitalization can hurt your SEO and readability.

Solution: Ensure that original text is properly capitalized, regardless of CSS styling.

27. Unnecessary Horizontal Scrolling

Problem: Horizontal scrolling often hides content, forcing users to work harder to consume information.

Solution: Avoid horizontal scrolling by keeping content within the natural vertical flow of the page.

28. Missing Calls to Action on 404 Pages

Problem: A 404 page without a call to action leaves users stranded.

Solution: Provide a search bar or links to common pages to help users find what they’re looking for.

29. Overuse of Paragraph Styles

Problem: Having more than two body paragraph styles can blur the distinction between paragraphs and headings.

Solution: Stick to one or two paragraph styles to maintain a clear and organized content structure.

30. Non-Clickable Link Blocks

Problem: When only the button inside a link block is clickable, users may miss the link entirely.

Solution: Make the entire block clickable to enhance usability and increase engagement.

31. Lacking Headings in Paragraph Blocks

Problem: Without headings, users can't easily scan content to decide if it's worth reading.

Solution: Include headings to break up text and guide users through your content.

32. Using Text Shadows as a Crutch

Problem: Relying on text shadows to make text readable is a Band-Aid solution for poor design choices.

Solution: Use an overlay to ensure text is readable, rather than masking the problem with shadows.

33. Inefficient Use of Sliders or Carousels

Problem: A single slider or carousel doesn’t present enough content at once, requiring more user interaction.

Solution: Use a grid of three sliders to display more content without extra clicks.

34. Relying on One-Page Websites

Problem: One-page websites often lack depth and fail to provide enough content to be truly valuable.

Solution: Ensure your website has enough content to warrant multiple pages, enhancing its value and SEO.

35. Full Background Colors on Titles

Problem: Titles with full background colors can be mistaken for buttons, leading to confusion.

Solution: Avoid full background colors on titles to maintain clarity and proper visual hierarchy.

36. Vague Button Text Like "Learn More"

Problem: Generic button text like "Learn More" provides no context and can be an accessibility issue.

Solution: Use descriptive button text that clearly indicates what users will learn or where they’ll go.

37. Obstructive Top Notification Banners

Problem: Banners that cover navigation make it harder for users to move around your site.

Solution: Ensure that top banners don’t interfere with navigation, and make them easily dismissible.

38. Overly Bold and Large Text for Design

Problem: Making text excessively bold or large for design purposes can make it difficult to read.

Solution: Use bold and large text sparingly, ensuring it remains legible and doesn’t strain the eyes.

39. Not Using Sticky Menus

Problem: Without a sticky menu, users may struggle to navigate your site, reducing engagement.

Solution: Implement sticky menus to make navigation easier and encourage users to explore more pages.

40. Text Smaller Than 12 Pixels

Problem: Text smaller than 12 pixels is hard to read, especially for users with vision problems.

Solution: Use a minimum of 12 pixels for text, with a preference for 17-18 pixels for body text.

41. Off-Canvas Menus for Contact Info

Problem: Off-canvas menus are commonly associated with navigation, not contact information, leading to user confusion.

Solution: Place contact information in a more prominent and expected location, rather than hiding it in off-canvas menus.

42. Decorative Borders Around the Viewport

Problem: Decorative borders on websites are outdated and distract from the content.

Solution: Avoid using decorative borders; focus on clean, content-centric designs instead.

43. Breadcrumbs Below the Fold

Problem: Breadcrumbs placed below the fold are less useful as they aren't immediately visible.

Solution: Position breadcrumbs at the top of the page, ensuring they are easy to find and use.

44. Unnecessary Search Functionality

Problem: Small websites with less than 10 pages don’t need a search function, which can clutter the design.

Solution: Reserve search functionality for larger websites or those with extensive content, like blogs.

45. Poor Grouping of Related Items

Problem: Items that should be grouped together but aren’t can confuse users and disrupt the flow.

Solution: Ensure related items are grouped closely, making it easier for users to understand the relationships between them.

46. Confusing Side-by-Side Calls to Action

Problem: Placing two calls to action side by side can split the user's attention and reduce effectiveness.

Solution: Design calls to action with a clear hierarchy and placement, guiding the user naturally to the desired action.

47. No Products on the Homepage of E-commerce Sites

Problem: E-commerce sites that don’t feature products on the homepage miss a key opportunity for conversion. (Table Reference: All e-commerce websites should have products on the homepage somewhere for better user experience.)

Solution: Display products prominently on the homepage to boost conversions and improve user experience.

48. Omitting Currency When Mentioning Pricing

Problem: Failing to include the currency when listing prices can confuse international visitors.

Solution: Always specify the currency next to pricing information to avoid misunderstandings.

49. Center-Aligned Drop-Down Menus

Problem: Center-aligning drop-down menus makes them harder to read and navigate.

Solution: Left-align drop-down menus for better readability and a more intuitive user experience.

50. Lack of a Sticky Header

Problem: Not having a sticky header forces users to scroll back up for navigation, which can be frustrating.

Solution: Implement a sticky header to keep navigation easily accessible, improving the overall user experience.
