I was just doing some research into a new project and stumbled across Alexa’s “by country” rankings. Alexa is one of the world’s top Web traffic monitoring firms, with a database of statistics on hundreds of thousands of Web sites. Their numbers aren’t perfect, of course. Alexa tracks search and traffic data only from its own community. But that community is mostly representative of the larger Web, and the Alexa numbers are invaluable not only for the insight they offer, but because this kind of traffic information is not publicly available anywhere else on the Web.
