In a nutshell: The quality of a link on a page can be estimated by the likelihood of a user clicking it. Links in the main content of a page are more likely to click than a footer, for example.

Other factors that affect the probability are, for example, the font size of the link, the order in the list of links the link is in, the type of link (tex, image), the destination of the link, and more.
