I have a question. I am assuming that it helps your site to have google tool bar and alexa tool bar installed. But not sure exactly if this is true. Is this so? i went and download and install the alexa tool bar, but don't have google's yet.
another think i wonder about google PR ranking and Alexa ranking is that does it count all of the traffic that comes to that site or only traffic from those individuals that have their tool bars? If this is the case, then for sure their rankings will be very biased!?
