Why You Should Test Landing Page Accessibility

Testing your landing pages ensures they are usable by everyone, removing barriers that might otherwise exclude millions of potential customers. An inaccessible website can prevent users with vision, hearing, mobility, or cognitive impairments from using your site effectively. This not only limits your audience but also reduces potential revenue.

The legal risks are becoming harder to ignore. In 2024 alone, over 4,000 ADA-related digital accessibility lawsuits were filed in U.S. courts. Experts predict this number could approach 5,000 by the end of 2025. For businesses operating in Europe, the European Accessibility Act (EAA), which takes effect in June 2025, adds another layer of compliance requirements. Failing to meet these standards not only puts you at risk for lawsuits but can also damage your brand’s reputation, especially as more consumers prioritize companies that demonstrate social responsibility and inclusivity.

Accessibility testing isn’t just about compliance - it’s about improving the experience for all users. Features like clear form labels, well-organized headings, and high-contrast buttons don’t just help users with disabilities; they also make your site easier to navigate for everyone. Achieving these benefits requires a combination of automated and manual testing.

Automated tools are great for quickly identifying technical issues, such as missing alt text or poor color contrast. However, they only catch about 25% to 40% of WCAG violations. Manual testing is indispensable for uncovering more complex issues, like keyboard traps, confusing screen reader navigation, or unclear alt text descriptions.

"No automated evaluation tool can tell you if your site is accessible, or even compliant. Human testing is always necessary because accessibility is about the human experience" - WebAIM

Combining both methods ensures no critical detail is missed.

A real-world example highlights the impact of this approach. In 2024, a mid-sized eCommerce store addressed accessibility issues by fixing hundreds of images without alt text and replacing color-only indicators. Their accessibility score jumped from 65% to 98% in just 48 hours. This blend of automation for speed and manual testing for precision is essential for creating landing pages that are both user-friendly and compliant.

Best Tools for Testing Landing Page Accessibility

Choosing the right tool for accessibility testing depends on your background and what you're looking to achieve. Some tools are built for developers to catch issues during coding, while others cater to marketers or content creators who need to ensure accessibility without diving into code. Here are five tools that cater to different levels of expertise and needs.

Silktide Toolbar

Silktide Toolbar is a free Chrome extension that’s perfect for non-developers. It performs over 200 automated WCAG checks, covering versions 2.0, 2.1, and 2.2 at Levels A, AA, and AAA. What sets it apart is its user-friendly approach - issues are explained in plain language. It also includes:

For PPC landing pages, WAVE and accessiBe accessScan provide the quickest accessibility checks, making them ideal for pre-launch campaigns. On the other hand, Axe DevTools is a great fit for ongoing development, ensuring issues are caught early in the workflow. Selecting the right tool not only ensures compliance but also enhances the effectiveness of your PPC campaigns.

Manual Testing Methods and Tips

Once you've automated your accessibility scans, it's time to complement them with manual testing. Why? Because automated tools can only catch a portion of potential issues - many problems require a hands-on approach to uncover. The best strategy combines automated scans with manual checks for areas like keyboard navigation, screen reader compatibility, and color contrast accuracy.

Keyboard Navigation Testing

Test your landing page by navigating it using only a keyboard. Use the Tab key to move forward through interactive elements and Shift + Tab to move backward. Activate links and buttons with Enter, and use the Spacebar for checkboxes and dropdowns. Here’s what to look for:

• Focus Indicators: Ensure every focusable element has a visible indicator with at least a 3:1 contrast ratio.
• Logical Tab Order: The navigation should follow a logical sequence.
• Keyboard Traps: Watch for areas where focus gets stuck (e.g., modal dialogs) without a way to escape using the Escape key.

This process ensures that users relying on keyboard navigation can interact with your page seamlessly. Once you've completed this, move on to testing with assistive technologies.

Screen Reader Testing

Screen reader testing is another critical step to catch issues that automated tools often miss. Start by having the screen reader list all headings and landmarks to ensure your page has a clear structure with defined regions like the header, main content, and footer. Then, test form fields and interactive elements to confirm they are announced correctly, including their "name, role, and value." Trigger form errors to check if error messages are properly linked to the relevant fields.

Here are some tools to get started:

• NVDA: A free option for Windows users.
• VoiceOver: Built into macOS and iOS devices.
• JAWS: A paid enterprise solution with advanced features.

These tools help ensure your content is understandable and navigable for screen reader users.

Color Contrast Verification

Manual color contrast checks are crucial because automated tools can miss issues in gradients, semi-transparent elements, or images used as backgrounds. Use tools like Chrome DevTools or the Colour Contrast Analyser app to extract HEX or RGB values from your foreground and background elements. Then, verify these values using a contrast calculator.

• Contrast Ratios: Normal text under 24px should meet a 4.5:1 ratio, while larger text should maintain at least 3:1.
• Interactive States: Check hover and focus states manually (:hover and :focus) to ensure they maintain proper contrast.
• Non-Underlined Links: Test three contrasts - link text vs. background, body text vs. background, and link text vs. surrounding content.

This step ensures your page meets accessibility standards for color contrast, making it easier for all users to read and interact with your content.

"A comprehensive accessibility testing plan must include manual testing. As automated testing generally only catches about 20-30% of accessibility errors, without manual testing the majority of issues are going to be missed." – CivicActions

Conclusion

Testing landing page accessibility isn’t just about meeting legal requirements - it’s about reaching millions of potential customers. With 26% of U.S. adults living with some form of disability, failing to make your page accessible can directly hurt your conversion rates. As Christy Smith, an Accessibility Tester, explains:

"If [your page] isn't accessible, you're losing customers. And even if it's technically accessible but a real pain … you're probably still going to lose some customers".

Tools like Silktide Toolbar, WAVE, AChecker, Axe DevTools, and accessiBe accessScan each bring something to the table. For example, Axe DevTools is great for developers, offering zero false positives. Meanwhile, WAVE helps content editors with visual overlays that make spotting issues simple. AChecker and accessScan provide quick compliance snapshots, and Silktide keeps tabs on accessibility over time.

For the best results, combine automated scans with manual testing. Start with automated tools, layer in manual checks, and keep monitoring your pages as you update content or launch new campaigns. This method ensures you catch as many issues as possible and keep your pages accessible long-term.

But accessibility isn’t just about compliance - it’s also good business. Accessible design often aligns with SEO best practices, improving the overall user experience. For instance, in September 2025, NPR reported a 6.86% boost in search traffic after adding transcripts to their audio content. This shows how prioritizing accessibility can drive performance. By adhering to standards like WCAG and the ADA, you’re not only meeting legal obligations but also creating landing pages that convert better and potentially reach 33% more people.

FAQs

Which tool should I start with if I’m not a developer?

AAArdvark is a fantastic starting point. It provides a free, easy-to-use homepage scan, making it ideal for teams that lack developer expertise. Another excellent choice is A11y Lens, a Chrome extension that generates exportable reports, specifically tailored for non-developers.
