2. What Is Web Accessibility
Some organisations may consider their websites to be "accessible" when the websites are easily found by search engines. However, the core principle of web accessibility is not about whether people "can find you", it is about designing sites for everyone, no matter who they are or how they access the Internet. It specifically addresses the needs of persons with disabilities, and ensures acceptable ease of use for all levels of ability.
The question you need to ask is:
"Can ALL people, including persons with disabilities, access the information that your website provides?"
By adopting relevant guidelines when designing websites to cater for the needs of persons with disabilities, you are making your website more user-friendly, maximising your customer base and showing that you are an organisation that cares.
