Why is it necessary to make web pages free standing? How do you make web pages free standing?

Free standing information's rationale is this: visitors do not always come through the front page. The site needs some sort of credibility. That is, how do visitors know that the site's information is relevant? Things that count as free standing information are the who, what, where, and when. For example, to make this midterm website credible, I have put my name on the site.
