To say that Web Analytics is hot is an understatement. Web analytics has, of course, been around almost since the beginning of the move to e-commerce and companies launching their first static websites. And though many software companies flocked to the marketplace, they probably moved too quickly. Organizations were not ready to leverage the vast amounts of information pouring out of their web applications. Many of these vendors did not survive more than a few years.
But the pursuit of web analytics has turned out to be more than tracking the number of visits, and the marketplace has seen a huge variety of open source technologies to help with the challenge of analyzing behavior on the web.
