The document discusses conversion rate optimization using big data and data science. It describes 3 opportunities for optimization: 1) user path analysis to understand customer journeys, 2) A/B testing using big data to experiment with variations, and 3) applying data science techniques. The solution framework involves collecting data from the web server, logs, tags and storing it in a big data framework. Real-time, customized recommendations can then be generated based on properties, users, sessions, clicks and login identity.
