I think that the Alexa toolbar is a great way to increase your Alexa ratings. I have been reading up on this and it has been said that you can increase your alexa ratings dramatically. So why not give that a try right. And while you are at alexa.com you mind as well get their alexa widget and put it on your site. This all takes a total of 2 minutes to do and supposedly you will see a jump in your ratings. So, I say why not give it a try!
