This document discusses how conversion rate optimization (CRO) is being replaced by customer journey optimization (CJO). It provides a 5-step plan to implement CJO, which includes mapping customer journeys, scoring interactions, identifying key "moments of truth", and optimizing those moments. An example of optimizing a customer's journey on an e-commerce site is shown. The key takeaways are that better customer journeys will lead to more conversions, and the 5-step plan can help companies map and prioritize touchpoints to improve journeys.
