Internet for all: Improving accessibility for consumers with disability

The Web and the Internet in whole is an increasingly important resource 
in many aspects of our life which includes: education, employment, 
government, commerce, health care, recreation, and more. It is important 
that the Web be accessible to everyone in order to provide equal access and 
equal opportunity to people with disabilities. An accessible Web can help
 people with disabilities participate more actively in society.

Also, an accessible website is often one of the easiest ways to do business
 with many people with disabilities, for instance, people who cannot read 
print material, people who have difficulty going to a physical store or mall,
 and others. Furthermore, what you do for accessibility overlaps with other
 best practices such as mobile Web design, usability, and search engine optimization (SEO)

An accessible website gives access to information and interaction for many
 people with disabilities. That is, the accessibility barriers to print, audio,
 and visual media can be much more easily overcome through Web 
technologies. Accessibility testing is challenging for testers as they are 
unfamiliar with disabilities so there are different ways of testing.
