The alexa pagerank is calculated from data collected from surfers that have the Alexa toolbar installed in their browser. Basically it is a measure of your popularity relative to the other sites. You can drop in the rankings and still get the same amount of traffic that you always did. The alexa pagerank of your website is affected by the traffic that visits your website and the traffic that all of the other websites receive. So you can have your page rank go up or down even if you get exactly the same amount of traffic every day. The change in your page rank would then be caused by the traffic the other sites on the internet get.
