Why Underlining Links is Still a UX Best Practice

Title: Why Underlining Links is Still a UX Best Practice

Introduction

In the evolving world of digital experiences, design trends come and go. From flat design to neumorphism, aesthetics continue to shift and adapt. Yet, some usability principles remain timeless—chief among them, underlining hyperlinks. While modern design tools tempt interface designers with cleaner, minimalist visuals, sacrificing clarity for style often leads to accessibility pitfalls.

Underlining links may seem like a simple design element, but this small visual cue plays a powerful role in user experience (UX), accessibility, and compliance alignment. This article explores why underlined links remain a UX best practice, especially for inclusive design, and how tools like allyWay help businesses on their accessibility journey.

This guide is crafted for business decision-makers, developers, web designers, and accessibility professionals seeking to improve usability, meet accessibility standards, and intentionally design for inclusion.

Why Underlining Links Matters in UX and Accessibility

Underlined text has long been the visual standard for hyperlink design. Users naturally associate underlining with clickable elements, thanks to decades of consistent digital conventions. Although modern CSS allows developers to alter how links appear using color, hover effects, or font changes, stripping away the underline comes at a cost—usability.

Visual Stability for All Users

When links are underlined:

• They are immediately recognizable as actionable items.
• Users with cognitive disabilities or learning difficulties experience less confusion.
• Scanability improves for all users navigating content quickly.

Removing underlines leaves designers dependent on color-only cues, which violates Web Content Accessibility Guidelines (WCAG). According to WCAG Success Criterion 1.4.1 Use of Color, color cannot be the only means to convey information. Individuals with color vision deficiency—older users or users with low vision—may entirely miss link cues based solely on color distinctions.

The Science of Link Recognition

Studies in cognitive psychology confirm that familiarity improves response rates. Underlined links leverage conditioned web behaviors, making user interactions faster and more intuitive. Even proficient web users benefit from the visual consistency.

According to Nielsen Norman Group’s usability research:

• Underlined, blue hyperlinks are far more likely to be recognized and clicked.
• Removing underlines increases task time and error rates.

So while some designers opt for aesthetic "cleanliness," the real cost may be accessibility, engagement, and conversion.

The Intersection of Accessibility Standards and Link Design

Designing inclusive web experiences is not just good UX—it aligns with major accessibility standards and regulations worldwide. Let’s explore how hyperlink presentation affects conformance with global accessibility frameworks.

Relevant WCAG 2.2 Criteria

The Web Content Accessibility Guidelines (WCAG), maintained by the W3C, outline how to make content perceivable, operable, understandable, and robust for users with disabilities.

Key WCAG success criteria related to link design:

• 1.4.1 Use of Color: Don’t rely on color alone to convey information.
• 1.4.3 Contrast (Minimum): Ensure sufficient contrast between text and background, including links.
• 3.2.4 Consistent Identification: Elements with the same function must be presented consistently throughout the site.

When links are only differentiated by color—and especially if those colors have insufficient contrast—they fail core accessibility checks.

EN 301 549 and European Compliance

The EN 301 549 standard, harmonized with WCAG 2.1 AA, governs web accessibility requirements for public sector organizations in the EU. Underlining links plays a vital role in ensuring non-color-reliant navigability and clear actionable elements across web content and applications.

U.S. ADA and Section 508 Implications

In the United States, the Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act influence digital accessibility norms. While neither law explicitly mandates underlining links, both emphasize the importance of equitable access—something underlined links help facilitate by reducing interface ambiguity.

Design Trends vs. Accessibility: The Ongoing Tension

Modern minimalist design encourages simplicity and whitespace, often encouraging designers to remove traditional elements like underlines for a more "sleek" look. But what works for visual aesthetics doesn’t always serve the user.

Common Design Pitfalls

1. Relying On Hover Effects
   Users on mobile or touch devices—where hover doesn’t exist—lose this cue.

2. Links Styled Like Text
   Users may entirely overlook these, especially when color contrast is poor.

3. Inconsistent Link Styling
   If some links are underlined and others are not, the user must guess interaction patterns.

Best Practice Tip:

Instead of removing underlines, refine them with CSS if needed (e.g., dotted or offset underline styles) to better match your design without losing usability.

Tips to Properly Style Links for Both Design and Accessibility

Design and accessibility can coexist with thoughtful implementations. Here’s how to keep everyone happy:

✅ Best Practices Checklist

• ✓ Underline all inline text links by default
• ✓ Use colors with minimum contrast ratio of 3:1 (text vs surrounding text)
• ✓ Avoid using underlines on non-links (e.g. for emphasis)
• ✓ Provide a visible focus indicator for keyboard users
• ✓ Maintain consistent link styles across all pages

Design-Friendly Link Styling Alternatives

If you must modify underlined link designs:

• Use border-bottom with lighter styling instead of full underline
• Add hover animation effects for engagement, not functionality
• Avoid link styling that mimics regular text (e.g. round corners, non-contrasting color)

Real-World Examples: Why Link Styling Matters

Consider two visually similar experiences with very different accessibility outcomes:

Website B demonstrates how a single detail—underlined links—can positively impact usability, accessibility, and even SEO (improved crawlability, higher engagement time).

How Link Accessibility Affects SEO

Clear link distinction isn't just good for users—it also supports better search engine performance.

Benefits:

1. Improved Engagement Metrics
   Users stay longer, reducing bounce rates. This signals content quality to search engines.

2. Better Internal Linking
   Underlined links encourage clicks to related content, improving crawl depth and reducing orphan pages.

3. Semantic Clarity
   Descriptive links (paired with visual cues) are more valuable to users and bots.

A website that nails UX fundamentals often ranks better—not just because of keyword usage but because of better user interaction design.

SEO Checklist for Link Best Practices

• ✓ Use descriptive anchor text
• ✓ Underline inline links or make them visually distinct
• ✓ Avoid “click here”—use contextual phrases
• ✓ Ensure links are keyboard-focusable
• ✓ Include internal links with value-rich content

Frequently Asked Questions (FAQs)

Should links always be underlined?

While there can be exceptions in certain components (e.g., buttons, nav menus), underlining should be the default for inline text links within content. It’s the most universally recognized standard and supports key accessibility goals.

Can I use color to distinguish links if the contrast is high?

WCAG allows color distinctions if contrast between link and surrounding text meets the 3:1 minimum and if there's an additional non-color cue like an underline or bold styling. Still, underlining is the most reliable method.

Will allyWay fix all link-related accessibility issues automatically?

No. allyWay supports businesses in addressing accessibility challenges, but does not guarantee legal compliance or automatically resolve all issues. It’s a support tool that enhances accessibility efforts through AI capabilities and user-guided configurations.

Is underlining considered outdated in modern UI/UX?

Not at all. While trends have shifted to minimalism, usability and accessibility outcomes should always drive design decisions. Underlining remains a modern best practice in inclusive design.

Conclusion: The Small Detail That Makes a Big Difference

In an era where websites strive for elegance and modern aesthetics, overlooking foundational usability principles like underlined text links can be a major setback. Good design is accessible design.
