Accessibility 101: Here’s what you need to know about web accessibility

When Tim Berners-Lee created the internet, he didn’t think it would turn out like this.

He envisioned it as a force for good – one that would level the playing field and bring equality to all. But 36 years later, that vision is still far from reality.

The internet remains inaccessible to many. Only now, with legislation like the European Accessibility Act (EAA) coming into force in 2025, are we seeing a real push to change that.

So, how can you be part of this change? 

By the end of this post, you’ll have discovered everything you need to know about accessibility – what it is, some of the legal requirements, and how it benefits both people and businesses alike. 

What is accessibility?

Making your website or mobile app accessible means ensuring that all users, including those with disabilities, can navigate, understand, and interact with your digital content.

Accessibility isn’t just about compliance. It’s about creating a better experience for everyone, strengthening your brand, and ensuring you reach the widest possible audience.

Types of accessibility

So, what does accessibility look like in practice? It spans multiple areas:

  • Web accessibility: Ensuring websites are navigable with screen readers, keyboard shortcuts, and alternative text for images.
  • Mobile accessibility: Designing apps and interfaces to be accessible across different devices. This means supporting features such as voice commands, gesture controls, and adaptive screen layouts.
  • Software accessibility: Making software more inclusive with customizable settings, voice-to-text capabilities, and adjustable fonts.
  • Content Accessibility: Ensuring that all digital content – text, images, and videos – is structured for easy understanding and navigation, including captions for videos and descriptive alt text for images.

Why accessibility matters in the digital world

Accessibility ensures that people with disabilities – including those with visual, auditory, cognitive, and motor impairments – can fully participate in the digital world. 

Technology plays an integral role in everyday life. Without accessibility, barriers prevent people from accessing education, employment, shopping, and even essential services. 

It ends up excluding a large number of people in our society. 

Besides the ethical considerations, accessibility is also important for business. 

Websites and apps designed with accessibility in mind often see increased engagement and conversion rates – as they offer a smoother, more intuitive experience for everyone. 

Accessibility features such as voice navigation, legible fonts, and high-contrast designs also improve usability for individuals without disabilities, making digital products more user-friendly overall.

Common barriers to accessibility

What is it about most websites and digital platforms that make them inaccessible? 

Many websites remain inaccessible due to common issues like:

  • Lack of alternative text for images: Screen readers rely on alt text to describe images to visually impaired users.
  • Poor color contrast: Low contrast between text and background makes reading difficult for users with visual impairments.
  • Inaccessible forms: Forms that lack proper labels and instructions can be difficult to complete using assistive technology.
  • Inconsistent or complex navigation: Poorly structured menus and unclear headings make it hard for users to find the information they need.
  • Lack of keyboard accessibility: Some users rely on keyboards instead of mice or touchscreens. Inaccessible designs make navigation difficult.
  • Uncaptioned audio and video content: Hearing-impaired users need captions to understand multimedia content.

WCAG guidelines

The Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium (W3C) and founded by Tim Berners-Lee, set the international standard for digital accessibility.

Adhering to WCAG helps businesses and organizations create a more inclusive digital space while ensuring compliance with various accessibility laws worldwide. Following these guidelines not only reduces legal risks but also improves user engagement, SEO performance, and overall user satisfaction.

WCAG is continuously updated to reflect technological advancements and the changing needs of users with disabilities. Staying informed on the latest updates ensures that your website remains accessible and compliant with evolving standards.

Key principles of accessibility

The WCAG are built on four key principles, commonly referred to as POUR. This stands for Perceivable, Operable, Understandable, and Robust. 

Ensuring your website or app and its content align with these key principles means you’re on the right track when it comes to accessibility.

Perceivable

Content must be presented in ways that users can perceive. This means providing text alternatives for images, ensuring there’s enough color contrast so text is easy to read, and offering captions for multimedia content.

Operable

Users must be able to navigate and interact with the content using different input methods, including keyboards and screen readers. Important things to keep in mind include avoiding flashing elements that could trigger seizures and ensuring buttons and links are accessible.

Understandable

Information and navigation must be clear so people don’t get confused. This involves having a structure that makes information easy to find, legible fonts, and clear instructions for interactive elements.

Robust

Content must also be compatible with current assistive technology and future developments. Using standardized coding practices and adhering to accessibility guidelines ensures that websites, apps, and their content will be accessible long into the future.

How you can improve accessibility

The great news is that improving accessibility doesn’t have to be complicated. Here’s where you can start:

  • Conduct regular accessibility audits: Use automated tools and manual testing to identify and fix accessibility issues.
  • Use accessible design principles from the start: Designing with accessibility in mind prevents costly fixes in the future. 
  • Provide text alternatives for multimedia content: Include captions, transcripts, and audio descriptions.
  • Ensure keyboard and screen reader compatibility: Test websites and apps to confirm usability without a mouse.
  • Offer clear and simple navigation: Use descriptive links, consistent menus, and logical content structure.
  • Implement proper color contrast and legible fonts: Ensure text is legible in all viewing conditions.
  • Test with real users, including those with disabilities: Getting feedback from actual users ensures your content is genuinely accessible. 

Making your website accessible

What does accessibility look like on a website? Below you’ll find some examples. Although it isn’t an exhaustive list, ensuring your website has these features will help make it more accessible:

  • Screen-reader compatible code
  • Adaptable contrast settings
  • Text resizing options
  • Keyboard navigation
  • Cursor enhancements for people with motor impairments
  • Adjustable controls for animations and dynamic content for people with epilepsy
  • Proper labels on all interactive elements on your site, so they’re compatible with assistive technology

Using inclusive design principles from the very beginning when creating your website is the easiest way to ensure accessibility. Making changes after the fact can involve some complex alterations to your code – but the right tools can make it easier

Countries worldwide are putting stringent laws and regulations in place to ensure greater accessibility. 

After all, with many essential services now digital, it’s more important than ever for governments to ensure everyone can access the services they need. 

Here are some of the laws and regulations around the world that mandate digital accessibility:

🇺🇸 Americans with Disabilities Act (ADA)

The ADA requires businesses operating in the United States to provide equal access to their digital services. While the law doesn’t explicitly outline web accessibility requirements, courts often interpret it to include websites and mobile applications. 

ADA compliance usually follows WCAG 2.1 Level AA standards, ensuring usability for individuals with disabilities.

🇺🇸 Section 508 (U.S.)

Section 508 of the Rehabilitation Act mandates that U.S. federal agencies and organizations receiving government funding must ensure their digital content is accessible.

It explicitly references WCAG 2.0 Level AA as the required standard. Government contractors and vendors must also meet these requirements when providing digital services to federal entities.

🇪🇺 European Accessibility Act (EAA)

The EAA establishes accessibility requirements across the European Union for digital products and services, including websites, apps, and e-commerce platforms. By June 2025, businesses providing digital services in the EU – regardless of where they’re based – must comply with these requirements to avoid penalties and ensure accessibility for all users. 

While the requirements draw from the WCAG, they differ slightly. This means it’s all the more important to make the EAA’s requirements the standard to adhere to in order to ensure compliance.

❓ Frequently Asked Questions about the European Accessibility Act


You need to comply with the European Accessibility Act (EAA) if you meet BOTH of these conditions:

  • Sell products or services to consumers in the EU
  • Meet at least ONE of the following criteria:
    • Have 10 or more employees
    • Have an annual turnover exceeding €2 million OR a balance sheet total exceeding €2 million

June 28, 2025. The EAA makes an important distinction:

  • For products: Only those placed on the market after June 28, 2025 must comply
  • For services: ALL services provided to consumers after June 28, 2025 must comply

If your website is offering products and services covered by the EAA, it falls under the EAA. However, certain website content may be exempt, provided that it is not updated after the EAA’s entry into force. This includes:

  • Pre-recorded time-based media published before June 28, 2025
  • Office file formats published before June 28, 2025
  • Online maps and mapping services, provided you offer essential navigational information in an accessible alternative format
  • Content qualifying as archives (not updated after June 28, 2025)
  • Third-party content not under your control

Yes, the EAA provides for transitional periods for services:

  • Service providers may continue to provide services using products that were lawfully used before the compliance date until June 28, 2030
  • Service contracts agreed before June 28, 2025, may continue without alteration until they expire, but no longer than five years from that date (until June 28, 2030)

The EAA leaves it to individual EU Member States to establish penalties. Each country will determine its own enforcement mechanisms and penalties under national laws, which may differ between Member States. The EAA only requires that these penalties be “effective, proportionate, and dissuasive.”

Purely informational websites that don’t offer any products or services covered by the EAA to consumers typically fall outside the directive’s scope. However, if your website includes contact forms for leads or calls-to-action for services that target consumers, it likely falls under the EAA’s scope.

The EAA covers specific products and services including:

For products:

  • Computers and operating systems
  • Self-service terminals (ATMs, ticketing machines, check-in machines)
  • Smartphones, tablets, and TV equipment
  • E-readers
  • Other consumer electronic devices for accessing audiovisual media services

For services:

  • E-commerce platforms
  • Banking services
  • Electronic communications
  • Services providing access to audiovisual media
  • E-books and dedicated software
  • Transportation-related websites and apps

The EAA focuses on products or services offered to consumers. The EAA defines consumers as “any natural person who purchases the relevant product or is a recipient of the relevant service for purposes which are outside his trade, business, craft or profession.” B2B websites, intranets, and learning management systems that are not intended for consumers generally fall outside the scope of the EAA.

B2B sites typically do not fall under the EAA’s scope as the act specifically targets consumer-facing services. However, if these B2B sites offer services directly to consumers, those consumer-facing portions would need to comply with accessibility requirements.

Yes, payment gateways integrated into consumer-facing websites must be accessible. Under the EAA, the entire purchasing process, including form fields, payment gateways, and confirmation messages, must be fully accessible.

The EAA explicitly exempts third-party content that you didn’t fund, develop, or control. However, for content that you do control (including PDFs, videos, and embedded software), the compliance requirements depend on timing:

  • Content published before June 28, 2025, that remains unchanged after this date is exempt
  • Content published before June 28, 2025, that gets updated after this date must comply
  • Content published after June 28, 2025, must comply with accessibility requirements

The EAA focuses on products and services offered to “consumers,” defined as natural persons using products or services for purposes outside their trade, business, craft, or profession. If your website offers goods or services to consumers, including through contact forms or CTAs, it generally falls under the EAA’s scope.

The EAA does not provide different rules specifically for non-profits. If a non-profit organization meets the criteria for compliance (over 10 employees or exceeding financial thresholds) and provides services to consumers, it should typically comply with the EAA requirements.

The EAA itself does not address specific funding mechanisms. However, it does note that if economic operators receive funding from outside sources specifically for improving accessibility, they cannot claim exemption under the “disproportionate burden” provision. Check with your local business support organizations or EU programs for potential funding opportunities.

While the EAA does not explicitly reference the Web Content Accessibility Guidelines (WCAG), the requirements are closely aligned with these standards. The EU is developing specific accessibility guidelines for private entities, building on existing standards like EN 301 549 (already established for public bodies).

According to Annex I, Section III of the EAA, general accessibility requirements include making information available through multiple sensory channels, presenting content in understandable formats, providing text alternatives to non-textual content, and ensuring websites are perceivable, operable, understandable, and robust.

Generally, following WCAG 2.1 guidelines is considered a good approach toward EAA compliance, though the EAA includes additional requirements beyond WCAG.

Yes, exemptions include:

  • Microenterprises (fewer than 10 employees AND annual turnover not exceeding €2 million OR annual balance sheet total not exceeding €2 million)
  • Cases where compliance would require a “fundamental alteration” to a product or service
  • Situations where compliance would impose a “disproportionate burden” on the economic operators concerned
  • Specific types of pre-existing content on websites and mobile applications

The EAA includes a “disproportionate burden” exemption. To qualify, you must conduct and document a formal assessment demonstrating why the cost of compliance would be excessive relative to the potential benefits for persons with disabilities. However, if you receive funding from other sources specifically for improving accessibility, you cannot claim this exemption.

The EAA does not explicitly provide for such a declaration. However, service providers are required to provide information on how their service meets accessibility requirements, commonly referred to as an accessibility statement. According to Annex V of the EAA, this should include a general description of the service in accessible formats, explanations necessary to understand its operation, and a description of how the relevant accessibility requirements are met.

If your service is not compliant, you are obligated to take corrective measures and inform the competent national authorities about the non-compliance and the corrective measures taken.

Yes, the EAA requires service providers to include information about how their service meets accessibility requirements. This typically takes the form of an accessibility statement that includes a description of the service, how it operates, and how it meets relevant accessibility requirements.

🌎 Other International Regulations

Many countries have enacted their own accessibility laws, often aligning with WCAG guidelines:

  • Canada: The Accessible Canada Act (ACA) requires digital accessibility compliance for federally regulated industries.
  • United Kingdom: The Equality Act 2010 includes web accessibility as part of its anti-discrimination mandates.
  • Australia: The Disability Discrimination Act (DDA) enforces digital accessibility requirements.

Benefits of accessibility for users and businesses

Besides legal compliance and ethics, accessibility is good for business. By making your website, app, and content accessible, you could reap rewards such as:

  • A strong user experience: Enhancing accessibility leads to greater engagement and user satisfaction, benefiting everyone.
  • More customers: Over 100 million people in the EU live with disabilities, making accessibility a significant market opportunity for your business. 
  • Keeping your customers for longer: Making digital services accessible helps retain users with disabilities as well as an aging population experiencing sensory and cognitive changes.
  • Less legal liability: Meeting accessibility regulations minimizes the risk of lawsuits, penalties, and costly remediation efforts.
  • SEO advantages: Search engines prioritize accessible websites, improving search rankings and online visibility.
  • Boosted brand image: A strong commitment to accessibility enhances your brand’s reputation and aligns with ethical business practices, resulting in more loyal customers.

Tools and resources for testing accessibility

Now you know you need to make your website and content accessible. But how do you find out how accessible your website is? Where do you even start?

The great news is that there are several tools that can help your business evaluate and enhance accessibility:

  • WAVE (Web Accessibility Evaluation Tool): Identifies accessibility issues on web pages.
  • Axe Accessibility Checker: Carries out a full accessibility audit of your website, detecting WCAG violations in digital products.
