Popularity

In common terms, Popularity is how many people like you and how much (remember your school days and the very cool guys everyone knew).

Well, that is pretty the same for websites. Here, we assume that if people (ie websites) like you, then they link to you. Very basically, the more you are linked to, the more you are liked, and the higher you are likely to appear in rankings.

This is a very basic overview. Next entry should be more detailed...
