You can make your website accessible to everyone by addressing five critical barriers: increase text contrast to 4.5:1 ratios, add descriptive alt text to images, label all form inputs clearly, ensure buttons have specific text, and use semantic HTML structure. These changes help 1.3 billion people with disabilities navigate your site effectively. Test with screen readers and keyboard navigation to identify issues that automated tools miss. Implementing WCAG Level AA standards transforms your site into an inclusive digital space that works for all users.
Understanding Current Web Accessibility Challenges
When you examine the current state of web accessibility, the figures paint a sobering picture that impacts millions of users daily. A staggering 96.8% of websites have detectable accessibility failures, creating barriers for the 1.3 billion people worldwide living with disabilities.
Your website likely contains an average of 51 distinct accessibility errors. These aren’t minor glitches—they’re significant obstacles preventing users from accessing your content.
These accessibility barriers aren’t just technical issues—they’re excluding real people from engaging with your digital presence.
The most common issues include low contrast text affecting 81% of pages, missing image descriptions on 54.5% of sites, and unlabelled form inputs appearing on nearly half of all websites. Despite these challenges, websites have become increasingly complex with an average of 1,257 elements per homepage, creating even more opportunities for accessibility barriers.
Here’s the frustrating part: mechanised tools only catch about 30% of accessibility problems. This means 90% of websites remain fundamentally unusable for people relying on assistive technologies.
Fixing the Most Common Barriers on Your Site
Now that you’ve seen the scope of accessibility problems, let’s tackle the barriers that are actually sabotaging your website’s usability. These five issues create the biggest headaches for users with disabilities – and they’re surprisingly easy to fix.
| Issue | Prevalence | Quick Fix |
|---|---|---|
| Low-contrast text | 79.1% of sites | Use 4.5:1 contrast ratio minimum |
| Missing alt text | 22.1% of images | Add descriptive text or alt=”” |
| Empty links | Top 5 errors | Write specific link descriptions |
| Unlabelled forms | 47.1% of sites | Connect labels to input fields |
| Empty buttons | 52.7% of sites | Add clear button text |
Start with contrast – it’s everywhere and impacts everyone. Then tackle your images and forms. You’ll eliminate most barriers within hours, not weeks. Regular website maintenance ensures these accessibility fixes stay in place and continue working properly as your site evolves. Neglecting these accessibility basics can expose your business to legal risks as digital accessibility lawsuits continue to rise across all industries.
Implementing WCAG Standards for Better Accessibility
You can’t just wing it when implementing WCAG standards—understanding the specific requirements at each conformance level will save you countless hours of backtracking later.
Level AA compliance demands more than good intentions, requiring systematic attention to contrast ratios, keyboard routing, and semantic HTML structure that automated tools simply can’t verify alone.
Manual testing methods become your safety net, catching the subtle accessibility barriers that only human evaluation and real assistive technology usage can reveal. The POUR principles provide the foundational framework that guides all WCAG implementation efforts across every conformance level.
Understanding WCAG Requirements
The backbone of web accessibility rests on the Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium to ensure your website works for everyone—including the millions of people with disabilities who navigate the digital world differently than you might expect.
These guidelines are organised around four POUR principles: Perceivable, Operable, Comprehensible, and Robust.
You’ll encounter three conformance levels that build upon each other. Level A covers minimum requirements like keyboard navigation and form labels. Level AA—your target—adds colour contrast ratios of 4.5:1 and logical heading structures. Level AAA provides exceptional accessibility but isn’t always achievable.
Most organisations aim for WCAG 2.1 AA, which includes 50 success criteria. This standard meets legal requirements while ensuring thorough accessibility for your users.
Manual Testing Methods
While automated tools catch obvious accessibility violations, manual testing reveals the subtle barriers that truly impact users with disabilities. You’ll need specific tools and methodical approaches to uncover these hidden problems.
Start with essential testing tools: browser extensions like WAVE and axe DevTools for real-time analysis, screen readers such as NVDA or VoiceOver for authentic experience simulation, and colour contrast analysers to verify readability. Disable your mouse completely—yes, completely—to test true keyboard accessibility across all interactive elements.
Your manual testing should include:
- Tab navigation through every clickable element to verify logical focus order
- Screen reader testing to ensure content flows coherently and makes sense
- Colour contrast verification meeting WCAG 2.1 Level AA standards (4.5:1 ratio)
- Form completion using only keyboard navigation and assistive technologies
Document everything meticulously.
Essential Technical Improvements That Make a Difference
Your website’s foundation begins with a clean HTML structure and properly labelled forms – two technical solutions that will significantly enhance the user experience for everyone.
When 39% of form inputs still lack proper labels, you are essentially creating invisible barriers for screen reader users who cannot understand what information you are requesting.
Getting these essentials right isn’t glamorous work, but it is the difference between a website that is accessible to all users and one that excludes millions of people.
Professional web development ensures that your site’s backend coding is structured to identify and rectify these accessibility issues before they affect your visitors.
Fix HTML Structure
Although many website owners focus on visual design and flashy features, fixing your HTML structure creates the invisible foundation that determines whether users can actually traverse and comprehend your content.
When you use semantic HTML elements like `
