A Pew Research survey found that just 62% of adults with disabilities owned a desktop or laptop, compared to 81% of those without disabilities. Additionally, only 72% of people with disabilities had smartphones, while 88% of people without disabilities did. People with disabilities were also three times more likely to report never going online and were less likely to use the internet daily.
In 2021, the non-profit organization WebAIM (Web Accessibility in Mind) conducted a review of the homepages of the top one million websites. They found that 97.4% of these pages didn’t meet one or more criteria from the Web Content Accessibility Guidelines (WCAG) 2.0 Level AA, the widely recognized standard for accessibility. On average, each page contained 51.4 accessibility errors.
Despite increased awareness of UX, many websites are still not fully tailored to meet the needs of users with disabilities. Most developers tend to create content for “ideal” or “typical” users, often overlooking the challenges faced by people with permanent, temporary, or situational disabilities.
If you want your website to be fully functional and UX-friendly, you need to make it accessible and truly inclusive. This article is here to guide you on how to make your website accessible for people with disabilities. The first step is to understand who they are and how they use the internet.
For instance, blind users often rely on desktop browsers like Webbie, which read site code aloud. Some browsers, like Firefox, also provide tools that make navigating the web easier for them.
It’s worth noting that blind users face difficulties when content is embedded in graphics, sliders, or scripts that their browsers cannot interpret. People with low vision, including those with color blindness, protanopia, tritanopia, and other visual impairments, often encounter challenges such as low contrast, cluttered visuals, or layouts that are hard to navigate.
And this is just scratching the surface. Many of us don’t fully grasp the challenges others face. Our communities also include neurodivergent individuals, people with cognitive impairments, epilepsy, and those with heightened sensitivity to sound. Designing your page with these users in mind is essential. And if you’re wondering – yes, it’s absolutely possible to create accessible websites that look amazing and perform even better.
Organizations like the World Wide Web Consortium (W3C) are leading the charge in accessibility and have published the Web Content Accessibility Guidelines (WCAG) to make the task easier.
So, what can developers and SEO specialists do to make websites more accessible and inclusive?
The WCAG 2.2, or Web Content Accessibility Guidelines, offer detailed guidance on how to make websites accessible to everyone, including users with disabilities. These guidelines were created by the Web Accessibility Initiative, a W3C project, and hold the status of an international ISO standard. They outline the key considerations that need to be addressed when building a website, setting the foundation for specific optimizations. Let’s explore some practical examples of these optimizations below.
The four core principles of accessibility under WCAG are summarized by the acronym POUR: Perceivable, Operable, Understandable, and Robust.
To fulfill the Perceivable principle, information and interface elements must be presented in ways that users can perceive. Operable means that interface and navigation elements must be functional – each element should have a defined role and purpose, triggering specific actions or serving a particular function. Understandable is straightforward: content should be easy to grasp, and the interface should be intuitive to use. Finally, for a website or app to be truly robust, it must be accurately, substantively, and technically prepared to ensure it’s properly interpreted by both users and assistive technologies.
In a nutshell, WCAG 2.2 principles push designers and developers to take deliberate, practical steps to create websites and applications with clear functions, simple and effective solutions, and purposeful designs that meet the needs of all users.
WCAG 2.2 is a more comprehensive and up-to-date set of guidelines for web accessibility compared to WCAG 2.0.
WCAG 2.2 introduces nine additional success criteria, including:
WCAG 2.2 introduces three levels of compliance: A, AA, and AAA. These levels indicate the extent to which a website meets the success criteria of WCAG.
Adapting a website to WCAG 2.2 will ensure it’s accessible to a broader audience, including individuals with disabilities.
Below, we’ll discuss five key aspects to enhance your website, making it more accessible for individuals with disabilities, especially those who are blind or visually impaired. Each aspect includes several elements that play a vital role in achieving optimal accessibility.
It turns out that maintaining clear and correct source code is essential not only for search engine crawlers but also for assistive technologies used by individuals who are blind, as these technologies read the code in a linear fashion. What elements should you focus on in this context?
Ensure that the order of elements on the page is logical and accurately reflects the sequence as recorded in the code.
Above is an example of how to structure a table correctly in the code. A browser designed for individuals who are blind will read the value immediately after the label. In a flawed version, the code would describe the label column first, followed by the values, while the visual layout would be adjusted using CSS.
Additionally, it’s essential to build the website so that users can navigate it using only the keyboard. This requires that all links be functional without the need for a mouse. Each <a> tag must include an href attribute, which is often overlooked when onclick events are used for links. To ensure the site is accessible, it’s important to present the links in the following way:

You can find an example of the correct way to structure a table in the code above. A browser designed for individuals who are blind will read the value right after the label. In an incorrect version, the code would first describe the label column, followed by the values, while the visual layout would be altered using CSS.
A well-structured website includes elements like a title, meta description, H1 header, H2 and H3 headers, and semantic text formatting – these elements are well-known to SEO specialists and are regularly optimized.
A readable layout is crucial for ensuring a positive user experience, especially for individuals with visual impairments.
To help users with disabilities navigate the site effectively, ensure it features a clear, organized menu with a well-defined category structure. Although using ALL CAPS might seem like a good way to make category names stand out, it actually doesn’t improve visibility. Words formatted like sentences are read faster because they have more distinguishing elements. For this reason, it’s better to avoid all-caps in the menu. Also, ensure there’s enough spacing between menu items, a strong contrast between the text and background, and a balanced font weight – not too light, but not too heavy.

You can make it easier for users to navigate your site by keeping a few key points in mind:
When optimizing web pages, we often focus on keyword-rich alt attributes to improve search engine visibility. However, for individuals with visual impairments, alternative descriptions are crucial for understanding the content of images. It’s important to remember that these descriptions should include not only keywords but also relevant context and details about the image.
Of course, it’s not always possible to meet all the graphic requirements mentioned above. In such cases, it’s helpful to offer buttons on the page that let users customize the design to their needs, e.g., adjust font size or contrast (e.g., black-and-white or black-and-yellow).

You can check your website’s accessibility in several ways:
Many of the optimizations that improve a website’s accessibility for individuals with disabilities also enhance its overall search engine performance. Key areas to focus on include clean code, a well-structured site hierarchy, clear layout, and intuitive navigation. By refining these aspects, you’ll not only make your site more accessible for blind and visually impaired users but also improve its visibility in general.
