What makes a site better?

Sometimes I wonder what is that we look for when we visit a site.
I know what I look for. I look for easy information retrieval process and where can I find the accurate information.

Thinking of the first part of my answer, I thought a great number of users depend on searching and navigation basically to retrieve the information from a website.

This led me to a new question. How to make the navigation a searching easier for the users?

My answer is making the navigation and search method intuitive. If the user can predict how the system will work then it becomes a lot easier to make the system user friendly. And obviously the method of information retrieval becomes easier.
