Title: Accessibility Author: Kriko Published: Feb 12, 2021 Last modified: Jul 14, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. A Letter # Accessibility **Accessibility** refers to the ability of individuals to access physical, digital, social, cultural and public spaces, products, services and information as independently, safely and equally as possible. This concept is especially critical for people with disabilities, older adults and different disadvantaged groups; however, it is not limited only to these groups. Users with temporary injuries, people browsing with a slow internet connection, users on small screens, people watching videos in noisy environments or users with different language and literacy levels can also benefit from accessible design. **Web accessibility** or **digital accessibility** means designing websites, mobile applications, electronic documents and digital interfaces so that they can be perceived, used, understood and technically accessed by the widest possible range of users. It is not enough for a website to look visually appealing. Users should be able to read content, navigate the page, complete forms, use buttons, understand videos and perform key actions without needing unnecessary assistance. Digital accessibility also includes building structures that are compatible with assistive technologies. Screen readers, keyboard navigation tools, voice command systems, magnification software, captions, transcripts and high-contrast settings are examples of these technologies. When websites and applications are developed to work with these tools, users with visual, hearing, motor or cognitive differences can interact with digital content more comfortably. For this reason, accessibility is not only a design issue; it is also a matter of software, content, UX and technical infrastructure. At the core of web accessibility is the ability of users to perceive content, operate the interface, understand information and access it through technology. For example, adding descriptive alternative text to images helps screen readers interpret the page correctly for blind users. Captions or transcripts should be added to videos for users with hearing difficulties. For users with color blindness, warnings should not rely only on color; additional indicators such as text, icons or patterns should also be used. Keyboard usability is also important for an accessible web experience. Some users may not be able to use a mouse or may have difficulty using a touchscreen. Therefore, menus, forms, buttons and links should be navigable with a keyboard. Focus indicators should be visible so that users can understand which element they are currently on. In addition, form error messages should be written clearly, errors should not be shown only through color changes and users should be told exactly what needs to be corrected. Content language is another important part of accessibility. Instead of long, complex and heavy sentences, content should use simple, clear and understandable language. Heading structure should be logical, paragraphs should be readable in length and users should be able to find the information they need easily. Especially in areas such as public services, healthcare, finance, education and e-commerce, users must clearly understand the steps they need to take. Accessibility is not only about technical compliance; it is also about clear communication. Mobile accessibility is also an important area of digital accessibility. Users access websites and applications from different screen sizes, devices and connection qualities. Therefore, text sizes should be readable, tappable areas should be large enough, the page should not require horizontal scrolling and the interface should work properly across different screens. In mobile applications, design should also be compatible with the accessibility features offered by iOS and Android. Accessibility tools available on platforms such as YouTube, Android and iOS provide good examples in this area. For example, TalkBack on Android helps blind or low- vision users interact with their devices through spoken feedback. On video platforms, features such as captions, automatic descriptions, keyboard shortcuts and audio descriptions can support a more accessible experience. However, to get the full benefit from these platform features, content creators and developers need to configure their content correctly. From an SEO perspective, accessibility can provide an indirect but important contribution. Proper heading hierarchy, meaningful link text, descriptive alt text for images, fast-loading pages, mobile compatibility and a user-friendly structure can support both accessibility and search engines' ability to understand the page better. However, accessibility should not be implemented only for SEO benefits. The main purpose should be to ensure that all users can participate equally in the digital experience. For brands, accessibility is important from ethical, legal, operational and commercial perspectives. An inaccessible website can prevent some users from accessing information, buying products, completing forms or receiving services. This weakens user experience and can damage the brand's perception of inclusiveness. In contrast, accessible design can help reach a wider audience, increase user satisfaction and strengthen brand trust. Accessibility should not be treated as a small feature added later. It should be planned from the beginning of the website, mobile application or digital product development process. Accessibility criteria should be considered during design, development, content creation, testing and post-launch maintenance. User testing, screen reader checks, keyboard navigation tests, contrast measurements and form usability analyses should be performed regularly. In summary, **accessibility** is a fundamental design and development approach that enables digital products and services to be used more easily, independently and equally by everyone. Web accessibility includes many elements such as alternative text, captions, keyboard compatibility, proper heading structure, sufficient contrast, clear language, mobile compatibility and compatibility with assistive technologies. A successful accessibility approach does not only support specific user groups; it creates a clearer, more usable and more reliable digital experience for all users. ## Discover it in the dictionary ### Search Volume Search volume is an SEO and digital marketing metric that shows how many times a specific keyword or phrase is searched within a given… ### Click Through Rate (CTR) Click Through Rate, commonly abbreviated as CTR, is a digital marketing metric that shows the percentage of users who click an ad or link… ### Frequency Capping Frequency is a media metric that shows how many times, on average, an advertisement is shown to a specific user or target audience.
