It’s also a legal requirement in many countries.

Key Reasons Accessibility Is Important:

Key Reasons Accessibility Is Important

  1. Legal Compliance – Avoid lawsuits under ADA, Section 508, and WCAG (Web Content Accessibility Guidelines).
  2. Better User Experience – A site that’s accessible is easier to use for everyone.
  3. SEO Benefits – Accessibility improvements often align with Google ranking factors (e.g., proper heading structure, alt text).
  4. Inclusive Brand Image – Shows you care about all customers.

Example: In 2024, several companies faced lawsuits for not having ADA-compliant websites, including retail brands and educational platforms.

How to Check Accessibility of a Website

Checking website accessibility involves automated testing, manual checks, and expert audits.
Let’s break it down step-by-step.

Step 1 – Run Automated Accessibility Checks

Automated tools quickly scan your site and detect common accessibility issues.

Step 2 – Perform Manual Accessibility Tests

Automated tools catch 40–50% of issues. Manual testing finds the rest.

Manual Checks Include:

  • Keyboard Navigation – Can users navigate your site without a mouse?
  • Color Contrast – Is text readable for users with low vision?
  • Alt Text Review – Are all images properly described?
  • Form Labels – Are forms easy to fill out with assistive technologies?

Example: Try navigating your homepage using only the Tab key — if you get lost or stuck, it’s a red flag.

Step 3 – Check If a Website Is ADA Compliant

Check If a Website Is ADA Compliant

ADA compliance means meeting WCAG 2.1 Level AA standards.

Checklist for ADA Compliance:

  • Text alternatives for non-text content
  • Captions for videos
  • Content is adaptable without losing information
  • Input assistance for forms
  • Contrast ratio of at least 4.5:1 for normal text

Step 4 – Measure Website Accessibility

Once you’ve identified issues, measure your accessibility score to track improvements.

Metrics to Track:

  • Accessibility Score (0–100 from Lighthouse or Accessibility Assistant)
  • Number of Issues Fixed vs. Remaining
  • Compliance Level (WCAG A, AA, AAA)
  • User Feedback from Assistive Tech Users

Step 5 – Schedule Ongoing Accessibility Audits

Accessibility isn’t a one-time task — it’s a continuous process.

Best Practices:

  • Test before every major update
  • Monitor with an automated tool monthly
  • Get feedback from real users with disabilities
  • Keep up with WCAG updates

Real-Life Example

A mid-sized online clothing retailer with ~15,000 monthly visitors and ~3,500 active products. The company had a growing customer base but noticed a high bounce rate (over 60%) and several complaints from users with disabilities who had trouble navigating the site.

Objective:

Improve website accessibility to meet WCAG 2.1 AA guidelines and ensure ADA compliance, while aiming to improve user experience and conversion rates.

Our Accessibility Audit Process

The retailer used Accessibility Assistant to run a full audit of their website. The process included:

  1. Automated Scan (using Accessibility Assistant Chrome extension)
  2. Manual Checks (keyboard navigation, screen reader tests, color contrast reviews)
  3. User Feedback from two volunteers who rely on assistive technology

Key Findings

IssueDescriptionImpact on Users
Missing alt text on 30% of product imagesMany product images had no descriptive alternative text.Users relying on screen readers couldn’t understand what the product was.
Poor contrast on call-to-action buttonsCTA buttons (e.g., “Add to Cart”) had light text on a pastel background with only a 2.5:1 contrast ratio.Low-vision users had trouble locating and reading important buttons.
Non-keyboard-accessible drop-down menusNavigation menus couldn’t be opened via keyboard-only navigation.Users with motor impairments couldn’t access certain product categories.

Fixes Implemented

  1. Alt Text for Images
    • Added detailed, keyword-rich descriptions for all product images.
    • Example: “Red cotton t-shirt with round neck and short sleeves – Men’s casual wear.”
  2. Improved Color Contrast
    • Adjusted button colors to meet WCAG AA contrast ratio (at least 4.5:1).
    • Example: Changed “Add to Cart” buttons from light blue text on pastel yellow to white text on dark navy blue.
  3. Keyboard-Friendly Menus
    • Updated menu scripts to ensure the Tab and Enter keys could fully operate the dropdown navigation.
