Making your website accessible isn’t just the correct thing to do; it’s a smart business move. The Web Content Accessibility Guidelines (WCAG 2.1) serve as the global standard for digital accessibility, providing best practices that help ensure your website is usable by all, including people with disabilities.

Here’s a practical checklist to help you achieve WCAG compliance, reduce legal risk, and improve customer experience.

WCAG compliance checklist: Core principles

 Perceivable

●      Provides text alternatives for all non-text content (e.g., alt text for images)

●      Uses captions and transcripts for audio-visual content

●      Ensures content is adaptable (e.g., resizable text, reflow)

●      Maintains sufficient color contrast (minimum 4.5:1 for text)

 Operable

●      Ensures all functionality is accessible via keyboard (no mouse needed)

●      Avoids content that flashes more than three times per second

●      Provides clear navigation (e.g., a consistent menu structure)

●      Includes skip links or headings to help users bypass repetitive content

Understandable

●      Uses plain language and clear instructions

●      Ensures web pages behave predictably (e.g., consistent user interface (UI))

●      Identifies input errors clearly and offers suggestions to fix them

Robust

●      Uses clean HTML/CSS code that works across browsers and assistive tech

●      Follows ARIA (Accessible Rich Internet Applications) standards where necessary

●      Validates code to avoid syntax errors

Why WCAG compliance matters

Complying with WCAG not only improves user experience but also helps you meet global accessibility laws such as the European Accessibility Act (EAA), the Americans with Disabilities Act (ADA), and the UK Equality Act 2010. Non-compliance can lead to legal penalties, customer churn, and reputational damage. 

That’s where an accessibility app can transform your site. It simplifies the process by automatically detecting and fixing the most common issues without costly development work. Better yet, it improves retention, boosts conversions, and unlocks access to the one in six global consumers with accessibility needs (WHO, 2023).

Accessibility is a journey, not a checkbox. With the right checklist and an accessibility app doing the heavy lifting, compliance and inclusion are within reach. Your customers will thank you for it.
