Deciding whether or not to launch a new product or feature is a resource management bet for any Internet business. Conducting rigorous online A/B tests flattens the risk.

- Understand the role of appropriate logging in data collection
- Determine how to frame your tests (size of difference detection, visitor sample size, etc.)
- Master the importance of testing for systematic biases
- Run power tests to determine how much data to collect
- Learn how experimenting on logged out users can introduce bias
- Understand when cannibalization is an issue and how to deal with it
- Review accepted A/B testing tools (Google Analytics, Vanity, Unbounce, among others)
