Making a better Internet
Alexa could not exist without the participation of the Alexa Toolbar community. Each member of the community, in addition to getting a useful tool, gives back. Simply by using the Alexa toolbar, every member contributes valuable information about the web, how it's used, what's important and what isn't. Alexa returns this information to the community as Traffic Ranks, Related Links, and more.
