Website accessibility is a critical aspect of modern web development. In 2025, ensuring that your website is accessible means not only complying with guidelines but also providing an inclusive user experience. Recent trends show that over 70% of digital experiences now integrate accessibility checks into their development lifecycle, with websites demonstrating improved user engagement by up to 50% when accessibility features are well implemented.
Understanding Website Accessibility
Accessibility in websites means designing and developing your site so that everyone—including people with disabilities—can navigate, understand, and interact with your content. It’s about removing barriers and ensuring equal access to information.
Is Your Infrastructure Ready for Global Traffic Spikes?
Unexpected load surges can disrupt your services. With LoadFocus’s cutting-edge Load Testing solutions, simulate real-world traffic from multiple global locations in a single test. Our advanced engine dynamically upscales and downscales virtual users in real time, delivering comprehensive reports that empower you to identify and resolve performance bottlenecks before they affect your users.
What is Website Accessibility?
Website accessibility involves designing web content that can be easily used by people with visual, auditory, cognitive, and motor disabilities. This ensures that no user is excluded from accessing your site’s information.
The 4 Principles of Web Accessibility
The core principles, often remembered by the acronym POUR, include:
- Perceivable: Information and user interface components must be presented in ways users can perceive.
- Operable: User interface components and navigation must be operable.
- Understandable: Information and the operation of the user interface must be understandable.
- Robust: Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.
The 4 Guidelines of WCAG
WCAG (Web Content Accessibility Guidelines) is organized under the same four principles:

Fair enough, but why leave it to chance? Uncover your website’s true limits with LoadFocus’s cloud-based Load Testing for Web Apps, Websites, and APIs. Avoid the risk of costly downtimes and missed opportunities—find out before your users do!
- Perceivable
- Operable
- Understandable
- Robust
The 20% Rule for Accessibility
The 20% rule suggests that if 20% or more of your audience has disabilities, your website should be designed with accessibility in mind. This benchmark serves as a practical guide for inclusive design strategies.
