Ok, so here is my first question since I am extremely new to this whole side of the industry. What are the various website ranking systems? I know PR so far, and I have briefly heard of Alexa (although still unsure what that means). I know this seems a little rudimentary to ask, but I need to learn this stuff somehow or another; I figured I would start with the pro's and go from there.
Website ranking depends on various factors like traffic, revenue etc., Alexa is one of the traffic ranking systems. Look at that site to see how websites are ranked.
