But in addition to offering approximated analytics, Alexa offers a unique feature its competitors don't. It is perhaps the key to your business's success: The ability to see where your competitors get their traffic.

This takes competitor research to a whole new level. I was astounded when I found out about this feature about a month ago to date.

By looking at your competitor, or competitors' traffic sources, you can get a better idea of the types of websites you should link on as well. Whether they are simply on thirty shopping directories, or use link exchanges. Whether they advertise on Facebook, or advertise on Myspace. Whether they advertise using banners, or text ads. All of this, and more, can be found with help from Alexa's great tool.

But don't just take my word for it, try it out for yourself, at www.Alexa.com/
