Web Accessibility
Web accessibility is a term that describes the accessibility of a website to navigation challenged people, such as disabled individuals. It refers to the practice of making websites usable by people of all abilities and disabilities. When sites are properly planned, designed, developed and optimised, all users (regardless of background or ability) can have equal access to information and functionality. This is really a representation of egalitarianism on cyberspace. For example, a site written with semantically meaningful mark-up, including textual descriptions provided for images and links named meaningfully, would help blind users utilising text-to-speech software or text-to-Braille hardware.
SEO Consult offers Web accessibility services that enable a website to conform with the UK's Disability Rights Commissions PAS 78 Specification.
If content is written in plain language and illustrated with instructional diagrams and animations, users with dyslexia and learning difficulties are better able to cope with it. People with poor eyesight can read website content more easily if it offers a font enlargement capability. Underlining or colour-differentiating hyperlinks will ensure that colour blind users can identify them appropriately. When navigation is made simpler so that a keyboard is all that is needed to navigate with, it would help people who have difficulty using a mouse. Creating large clickable areas and links helps users who cannot control a mouse with precision. Furthermore, featuring closed captioned videos or a sign language version enables users who are deaf or hard of hearing to understand video. When sites are correctly built and maintained, all of these users can be accommodated while not impacting on the usability of the site for non-disabled users.
The needs that SEO Consult Web accessibility aims to address include:
