The Web is an increasingly important resource in many aspects of life: education, employment, government, commerce, health care, recreation, and more. It is essential that the Web be accessible to provide equal access and equal opportunity to people with diverse abilities. The Web offers the possibility of unprecedented access to information and interaction for many people with disabilities. The accessibility barriers to print, audio, and visual media can be much more easily overcome through web technologies.
There is also a strong business case for accessibility. Accessibility overlaps with other best practices such as mobile web design, device independence, usability, design for older users, and search engine optimization. Accessible websites can have better search results, reduced maintenance costs, increased audience reach, and demonstrate corporate social responsibility.
