Which question needs to be answered to determine a website's authority?

what is the depth and breadth of the information?
who created the website, and what are the author's credentials?
when was the site created, and when was it last updated?
does the site include links, and do all of the links work?

Who created the website, and what are the author's credentials?

Explanation:

The date that the site was created, the links that it includes, or even the depth of the information do not prove authenticity of content. In fact, the credentials of the author do not either, but at least if the other works of the author do have prove of authenticity and are considered trustworthy, you can trust the website a little more than if you don't know who is behind it.
