Simply put, usability is making your website easy for your visitors to find the information they need when they need it. A common misconception about usability amongst web companies is that usability is expensive. Yes, there are multi-national companies that spend thousands of dollars on usability tests and research, but for an everyday company usability is achievable without the knowledge of usability experts or without expensive equipment for testing. Web designers have an even easier job to do, just by reading usability articles they can accumulate a fairly good knowledge about usability basics and how to implement them on a website.
