4. Accessibility Issues
The Web has become a very graphical medium, but not everyone can see it this way. Some people switch off graphics, others use machines that can only show text and other people have disabilities that make access to the Web difficult. You should design your site with accessibility issues top of your priorities. A well designed, accessible site has been shown to benefit all users and can increase the traffic your site receives.
There are legal requirements on site providers to make their sites as accessible as possible. The UK's Disability Discrimination Act (DDA), makes it illegal for you to include information on your site which is inaccessible to certain users. There are also legal regulations for web accessibility in other jurisdictions e.g.European Union, US and Australia set out requirements for accessible design.
