What makes a "friendly url"?

@mike 

A "friendly URL" is a web address that is easy to read, remember, and type, and accurately describes the content it points to. It typically includes keywords relevant to the content and is structured in a logical and organized manner. Friendly URLs are typically short, avoiding the use of numbers and special characters, and can be easily shared and understood by both humans and search engines. They are also often lowercase and use hyphens to separate words.
