As some web designers think, web design is not just a collection and alignment of pretty pictures and some text. Instead it is a process which creates a very important and effective communication and marketing tool, which is what we call a website. With so much information and interaction to be effected on a website, it is critical that it should have it all in a very usable manner. Usability is fundamental to an effective website.
Adherence to Web Standards
Usability in a web design cannot be achieved without adherence to web standards. Adherence to web standards is not only important for achieving usability but it also helps in making a website Search Engine friendly, which enhances the prospects of a website to be more successful on the web.
