Where do Alexa’s Top Sites by Category come from?

The Top Sites by Category is a directory on Alexa.com that was created with a copy of the Open Directory Project, previously located at http://www.dmoz.org. The Open Directory Project contained over 4 million sites in over 590,000 categories. The directory was maintained by over 73,000 volunteer editors around the world.

You can access all of Alexa’s helpful site information just by clicking on the title of any site.
