Website accessibility compliance means designing and building your website so that people with disabilities — including visual, auditory, motor, and cognitive impairments — can perceive, navigate, and interact with your content effectively. The Americans with Disabilities Act (ADA) applies to business websites, and non-compliance exposes you to legal risk: over 4,600 web accessibility lawsuits were filed in the US in 2023, a 14% increase from 2022 according to UsableNet’s year-end report, with small businesses increasingly targeted alongside major corporations.

You built your website to attract customers, not to exclude them. But if your site cannot be used by someone navigating with a screen reader, someone who cannot use a mouse, or someone with low vision who needs high contrast text — you are excluding roughly 26% of American adults who live with a disability (CDC, 2023). Beyond the legal risk, inaccessible websites lose customers. The Click-Away Pound Survey found that 71% of disabled consumers leave websites they find difficult to use, representing $6.9 billion in annual lost revenue across UK and US markets.

This guide explains what website accessibility means in practical terms, the specific compliance standards your site needs to meet, the most common accessibility failures and how to fix them, and how to maintain accessibility as your site evolves.

What Does Website Accessibility Actually Require?

Website accessibility requires conformance to the Web Content Accessibility Guidelines (WCAG), the internationally recognized standard developed by the W3C. WCAG 2.1 Level AA is the benchmark most courts and regulators reference when evaluating website accessibility compliance. The guidelines are organized around four principles — perceivable, operable, understandable, and robust — which together ensure that all users, regardless of ability, can access your website’s content and functionality.

The Department of Justice issued a final rule in April 2024 requiring state and local government websites to comply with WCAG 2.1 Level AA, and federal courts have consistently applied ADA Title III requirements to commercial websites. While no single federal law explicitly mandates WCAG compliance for private business websites, the legal precedent is clear: if your website is inaccessible to people with disabilities, you can be sued under the ADA, and courts have overwhelmingly sided with plaintiffs in these cases.

The Four Principles of WCAG Compliance

Every WCAG requirement falls under one of these four principles. Understanding them helps you evaluate your own site:

  • Perceivable: All content must be presentable in ways users can perceive. This means providing text alternatives for images (alt text), captions for videos, sufficient color contrast between text and backgrounds, and content that does not rely solely on color to convey meaning. If someone cannot see an image, they need descriptive alt text. If someone cannot hear a video, they need captions
  • Operable: All navigation and interactive elements must be usable with a keyboard alone — no mouse required. This includes being able to tab through links and form fields, skip navigation menus, and interact with all buttons and controls. Time limits must be adjustable, and content cannot flash more than three times per second (seizure risk)
  • Understandable: Content and interface behavior must be predictable and readable. Use clear language, consistent navigation, label form fields explicitly, and provide helpful error messages that explain what went wrong and how to fix it. Your site should behave the way users expect it to
  • Robust: Your website must work reliably across assistive technologies — screen readers, voice navigation tools, braille displays, and switch devices. This requires clean, valid HTML markup, proper use of ARIA labels where needed, and compatibility with current and future assistive technology

What Are the Most Common Accessibility Failures on Small Business Websites?

The most common accessibility failures on small business websites are missing image alt text, insufficient color contrast, empty or missing form labels, missing document language, empty links or buttons, and missing skip navigation links. WebAIM’s 2024 analysis of one million homepages found an average of 56.8 accessibility errors per page, with 95.9% of homepages having detectable WCAG failures — meaning your site almost certainly has accessibility issues that need fixing.

The encouraging news is that most accessibility issues are straightforward to fix once identified. A professional web design team builds accessibility into the development process, but even existing sites can be significantly improved by addressing the most common failures. These fixes also improve SEO performance because search engines value the same structured, well-labeled content that assistive technologies require.

The Top Accessibility Issues and How to Fix Them

Address these six issues first — they account for the vast majority of accessibility failures on small business websites:

  • Missing alt text on images (68% of homepages): Every meaningful image needs descriptive alt text that conveys its purpose. A photo of your team should say “Spilt Media team at our Fort Pierce office” not “IMG_4523.jpg” or blank. Decorative images that add no information should have empty alt attributes (alt=””) so screen readers skip them
  • Low color contrast (81% of homepages): Text must have a contrast ratio of at least 4.5:1 against its background for normal text and 3:1 for large text. Light gray text on a white background fails. Use a contrast checker tool like WebAIM’s contrast checker to verify. This is especially common on mobile-friendly designs where trendy light color palettes sacrifice readability
  • Missing form labels (45% of homepages): Every form field — name, email, phone, message — must have a visible label explicitly associated with the field using the HTML “for” attribute. Placeholder text inside the field is not sufficient because it disappears when the user starts typing
  • Empty links or buttons (50% of homepages): Links and buttons must contain descriptive text or an aria-label. Social media icons that are just images inside links need aria-labels like “Visit our Facebook page.” A link that just says “Click here” is both an accessibility failure and a missed SEO opportunity
  • Missing document language (18% of homepages): Your HTML tag needs a lang attribute (lang=”en” for English). This tells screen readers which language to use for pronunciation. A single missing attribute makes your entire site harder for screen reader users
  • No skip navigation link: Keyboard users need a “Skip to main content” link at the top of each page so they do not have to tab through your entire navigation menu on every page load. This is a quick fix that dramatically improves the keyboard navigation experience

How Do You Test Your Website for Accessibility?

You test your website for accessibility using a combination of automated scanning tools that catch technical violations and manual testing that evaluates the actual user experience. Automated tools catch approximately 30-40% of WCAG issues according to the Government Digital Service’s research — the remaining 60-70% require human evaluation, such as testing keyboard navigation, verifying that alt text is actually meaningful, and confirming that the reading order makes logical sense.

Start with automated tools to identify the low-hanging fruit, fix those issues, then perform manual testing to catch what the tools miss. A comprehensive accessibility audit from a qualified consultant costs $2,000-$10,000 depending on site size, but you can make significant improvements on your own using free tools and the checklist below.

Accessibility Testing Tools and Techniques

Use these tools and methods to evaluate and improve your site’s accessibility:

  • WAVE Web Accessibility Evaluator (free): Developed by WebAIM, WAVE adds visual indicators to your page showing accessibility errors, warnings, and features. Available as a browser extension or web-based tool. Start here — it gives you an immediate visual overview of your page’s accessibility status
  • Google Lighthouse (free, built into Chrome): Open Chrome DevTools, click the Lighthouse tab, and run an accessibility audit. Lighthouse scores your page 0-100 and lists specific failures with links to fix instructions. Also checks page speed and SEO simultaneously
  • Keyboard navigation test (manual): Put your mouse away and try navigating your entire website using only the Tab key, Enter, and arrow keys. Can you reach every link, button, and form field? Can you see where the focus is at all times? Can you submit a form? If you get stuck, keyboard users get stuck too
  • Screen reader test (manual): Download NVDA (free for Windows) or use VoiceOver (built into Mac/iOS) and listen to your website being read aloud. Does the content make sense in the order it is read? Are images described? Are form fields identified? This test reveals issues no automated tool catches
  • Color contrast analyzer (free): Use WebAIM’s contrast checker or the Colour Contrast Analyser app to verify every text/background combination on your site meets WCAG minimum ratios. Pay special attention to text over images, colored buttons, and footer text

Website accessibility is not a one-time project — it requires ongoing attention as you add new content, update designs, and install new functionality. Every page you publish, every image you add, and every form you create needs to meet accessibility standards. Building accessibility into your workflow is far more efficient than retrofitting it later. If you want a professional accessibility audit of your website or need help bringing your site into compliance, schedule a free consultation with Spilt Media’s web development team.

Frequently Asked Questions

Can my small business really get sued for an inaccessible website?

Yes. Over 4,600 web accessibility lawsuits were filed in 2023, and small businesses are increasingly targeted. Demand letters from accessibility law firms often seek $5,000-$25,000 in settlements. Several serial plaintiffs and law firms specifically target small business websites with easily detectable violations. Compliance is significantly cheaper than litigation — most small business sites can be made substantially compliant for $1,000-$5,000 in remediation work.

Do accessibility overlay widgets actually work?

Accessibility overlay widgets (like AccessiBe, UserWay, and AudioEye) add a toolbar to your site that lets users adjust font size, contrast, and other display settings. However, the accessibility community and legal experts widely agree that overlays do not achieve WCAG compliance. The National Federation of the Blind issued a statement opposing overlays, and multiple lawsuits have been filed against websites using overlays. Fix the underlying code rather than adding a Band-Aid that may actually create additional accessibility barriers.

Does website accessibility help with SEO?

Significantly. Many accessibility best practices directly improve SEO: descriptive alt text helps Google understand your images, proper heading hierarchy helps crawlers understand content structure, clean HTML improves crawlability, and fast load times (required for accessibility) are a ranking factor. A 2023 Semrush study found that sites with higher accessibility scores averaged 12% more organic traffic than comparable sites with lower scores. Accessibility and SEO reinforce each other.

What level of WCAG compliance do I need?

WCAG 2.1 Level AA is the standard most courts and regulators reference. Level A covers the bare minimum (without which some users literally cannot access your content). Level AA adds requirements for color contrast, resizable text, and more comprehensive navigation. Level AAA is aspirational — few websites achieve full AAA compliance, and it is not typically required. Target Level AA as your compliance goal, and you will meet the expectations of virtually any legal or regulatory standard currently applied to commercial websites.

How often should I audit my website for accessibility?

Run a comprehensive accessibility audit annually and perform spot checks after any significant design changes, new feature additions, or content management system updates. If you publish blog content regularly, check that new posts include proper alt text, heading hierarchy, and link text as part of your publishing workflow. Automated monitoring tools like Siteimprove or Monsido can continuously scan for new accessibility issues and alert you when problems are introduced.
