We just posted a new video on the Website Optimizer YouTube channel that shows the power of website testing. Last month, we held our annual Google Partner Summit where we hosted all of the Google Analytics, Website Optimizer, and Urchin Software Authorized Consultants. One of the keynote speakers was Dan Siroker, Director of Analytics for the Obama Presidential campaign.

In his 50 minute talk, Dan explained how they used data to win the election. He shows how they used tools like Google Analytics and Website Optimizer to get more engagement and more donations. He also describes the lessons that they learned throughout the campaign. With the successful election behind him, Dan is now focused on his startup, CarrotSticks , and he explains how he's using the same principles within his own company.
